Recycling glass. Glass recycling - save nature and make money

A family of several people purchases about 10 units of glass containers monthly, along with juices, drinks and pickles. And if cans are considered a necessary household item, then most bottles are most often sent to the trash bin. But recycling glass allows you to make many new useful things from waste.

Cans and bottles can be used endlessly, because glass is a material that is 100% suitable for reuse. In our country, the mechanism for collecting used packaging has been established in almost all populated areas, but the majority of ordinary citizens still send it to a landfill. Isn't it better to be more conscious and recycle the glass? Moreover, although such disposal costs money, it prevents the creation of many tons of garbage waste.

Features of waste processing in Russia

Glass recycling in Russia is ongoing. According to research data, the annual collection of such waste is about 3.5 million tons. The collected containers are used in two ways:

Whole cans and bottles are washed, disinfected and reused;
- substandard items are broken down and sent for further processing.

Just 5 years ago, 97% of all collected containers in Russia were reused and only 3% were cullet. But since 2012, technical regulations have banned reuse of all glass packaging that came into contact with baby food, which significantly increased the share of such waste in the total mass of collected containers.

Recycling of broken glass is carried out in several stages:

Automatic sorting and grinding of recyclable materials;
- removal of metal inclusions (stoppers, caps) using a magnet;
- adding raw materials (sand, soda and limestone) to glass chips to improve the properties of the finished product;
- glass melting in a special furnace at a temperature of 1200–1500°C. It is worth noting that broken glass melts at a lower temperature than the original raw material, which significantly reduces energy costs;
- molding of new products;
- annealing of finished cans and bottles to increase the strength of the packaging;
- visual and technical quality control of glass containers.

It is worth noting that in Russia the recycling process is not limited to the production of new bottles and cans. In our country, decorative and heat-resistant tableware is produced from recycled materials, as well as ceramic sanitary ware, water filters, construction, insulating, abrasive and other materials.

What are the benefits of recycling used glass bottles?

Everyone knows that continued use of waste is good. But let's move away from general formulations and look at the specific benefits of recycling glass waste.

• Preservation environment. Glass production requires sand, which is mined in quarries. To do this, huge holes are dug on the surface of the earth, and sometimes forests are cut down to clear the work site. After developing one quarry, people begin to destroy nature in another place. Many of us feel regret at the sight of cut down trees and abandoned quarries, but... we continue to throw bottles in the trash.
• Preservation natural resources. The main components of glass are sand, limestone and soda ash. On this moment people do not lack these types of raw materials, but everything has an end. If we talk about specific figures, one ton of recycled glass saves at least 500 kg of sand, 200 kg of limestone and 150 kg of soda.
• Conservation of energy resources. Primary glass production itself involves high energy costs. But in addition to this, energy is spent on mining and recycling of already used containers. Scientists have calculated that just 2 recycled bottles release enough energy to boil 1 kettle of water.
• Reducing the area of ​​solid waste landfills. The decomposition time of glass is about 1000 years, which means that each existing landfill will be inherited by another 12–15 generations of people. But this is half the problem, because after some landfills are filled and closed, more and more landfills have to be opened. Meanwhile recycling glass significantly reduces waste volumes and saves about 10,000 hectares of land annually.

Problems of glass container recycling

Most Russian citizens are in no hurry to hand over cans and bottles. Some consider this activity shameful, because most often they are rented out by tramps and the poor. Others don't even think about the problem of environmental pollution and throw away bottles along with other household waste.

Be conscious and at least organize separate waste collection in your home, because glass is a fairly profitable resource: for one standard bottle at the collection point you will receive about two rubles, for a non-standard product - from 20 to 80 kopecks. You may not get rich, but you will contribute to the preservation of the main wealth - pristine nature!

Glass recycling is an important industry in waste management, necessary to protect the environment and conserve natural resources. However, in Russia this area is poorly developed and large quantity glass is not recycled. This article is about why it is necessary to recycle glass waste and how this processing is done.

It is necessary to hand over glass bottles and cullet to collection points for further processing for a number of reasons:

1. Glass is not biodegradable. A simple glass soda bottle has a decomposition time of 1,000 years or more. It is clear that without the disposal and recycling of glass, our entire planet would be completely filled with glass waste in a short period of time.
2. Glass products are fragile; broken glass released into the environment poses a threat to both animals and people.
3. Glass-contaminated soil is unfavorable for vegetation growth.
4. Reusing glass containers and cullet allows you to save natural (exhaustible and non-renewable) resources. So, for example, using 10% broken glass helps save gas by 3%. If a person engaged in the production of glass products uses only broken glass in his enterprise, he will thereby reduce gas consumption by 30%.
5. In Russia, a relatively small proportion of glass waste is recycled. But even this amount of recycled waste ensures the conservation of about 10,000 hectares of land that could turn into huge landfills.
6. Glass containers and cullet are completely recyclable materials, that is, glass recycling is waste-free, which is extremely important for protecting the environment from the negative influence of industrial and other enterprises.
7. Besides natural gas, reuse of this type of waste allows saving more than 1 ton of materials used in production such as limestone, soda, sand.
8. People who hand over glass containers to collection points receive money for it.

Important! Glass recycling is necessary, first of all, to protect our environment, to save natural resources and to produce glass products and materials cheaper.

Which glass is recyclable?

The main types of recycled glass waste include:

1. Glass containers: glass jars and bottles. Usually people collect bottles and hand them over to specialized points that accept glass. The glass containers are then recycled for reuse. At the same time, it is washed and treated with disinfectant solutions, after which the glass container can again be used as a container for drinks.
2. Cullet - broken glass containers.

Broken glass is classified depending on its color. For example, green cullet (GC), colorless cullet (BS), brown cullet (KS), etc.

Note! All glass materials for different products are made on the basis of the same substances (as mentioned earlier, sand, soda, and lime are used). However, various impurities are added to a number of glass products (for example, windows, light bulbs), and the surface of many products is also treated with various special coatings. For this reason, only glass bottles and jars can be recycled.

Glass recycling at home

Recycling glass at home is possible, but it requires some time and effort. Such recycling primarily involves processing entire glass containers for reuse. To do this, it is necessary to thoroughly rinse glass containers, treat them with disinfectants available at home or specially purchased in a store, and then rinse the treated containers with special care with clean running water. After these steps, cans and bottles can be used again without any harm to health.

An interesting question is how to recycle glass at home.

Cullet can be recycled independently. However, this will require much more time. Let's give an example.

At home, glass can be recycled into tiles (if there is enough glass material). To make tiles, you only need three components: glass, dyes and binders. The glass (cullet) must be crushed, then dyes must be added to the glass mass to obtain the desired color of the tile and a binding compound, then the mixture must be poured into the desired form and left to harden for a while, after which the tile will be ready for use. These tiles are better suited for bathroom and kitchen walls.

How to recycle glass

Disposal and recycling of cullet is a step-by-step process consisting of the following main stages:

• collection of glass waste;
• transportation of collected waste to a glass recycling plant;
• separation, purification from various impurities, waste washing;
• crushing glass using special equipment, grinding small pieces into powder;
• packaging of produced glass powder for subsequent use.

Recycling glass bottles (or rather, defective and broken bottles) directly at the glass container production plant itself is a competent and rational waste disposal. Let's look at how this process is carried out.

1. Stage one. Separation of all non-glass components from the cullet. Grinding the culls and separating the remaining metal parts using magnets. Separation of plastic and paper components from the crushed mixture in vacuum processes.
2. Stage two. Sending the resulting mixture for secondary production of containers. The waste is added to the feedstock (lime, soda, etc.), then the mixture is mixed and converted (at 1500 o C) into a glass fraction.
3. Stage three. Pouring glass mass into molding containers, blowing new bottles.

The quality of such a bottle, produced by recycling glass, corresponds to the quality of a bottle made from 100% fresh raw materials. The use of cullet in the production of glass containers significantly saves energy.

Large glass processing plants in Russia: RSK company (in St. Petersburg, Yaroslavl and other cities), Utilita, etc.

Glass processing equipment

Modern fairly wealthy enterprises use such basic equipment for glass processing as:

• automatic systems that sort cullet by color and shade;
• containers for sorted waste;
• sinks for dirty fights with paper residues;
• different types of filter sieves;
• electromagnetic and vacuum equipment;
• crushers;
• belt conveyor;
• packaging systems.

Who accepts glass for recycling?

Glass containers and broken glass are usually accepted at collection points located in most Russian cities. Such points are organized by individual entrepreneurs, since glass is a recyclable material that can be profitably sold to factories for the production of glass products. Also, containers and scraps are accepted by companies involved in glass processing and/or production of glass products.

Cost of glass as recycled material

Perhaps everyone has at one time or another thought about how much crushed glass costs as recyclables.

Glass containers and cullet are purchased by many companies for further use as secondary raw materials. Prices for glass in our country are low. So, for 1 bottle you can get from 10 kopecks to 2 rubles. Fight can be sold on average for 3000 - 4000 rubles per 1 ton, depending on the type.

Glass recycling as a business

You can build a great business out of glass waste. Such waste can be used by entrepreneurs in the production of sanitary ware from ceramics, bricks, glass powders, fine-grained concrete, heat insulators, etc. At the same time, it is not necessary to create a large enterprise; you can open a mini-factory for the production of products from cullet. A current business idea is to produce tiles from glass waste.

The following video explains how to properly organize a glass waste recycling business and how this processing should be carried out.

Relevance of glass recycling in Russia

Glass recycling in Russia is a very pressing problem today. The amount of waste is constantly increasing, and the development of glass processing industries is poor. Therefore, a glass waste recycling business can be a solution to this difficult environmental and economic challenge.

Thus, recycling glass containers and cullet is not only an activity aimed at protecting our environment, but also a promising business, the development of which requires, among other things, government support. As a business, glass recycling is profitable and sustainable when properly managed.

Entrepreneurs who are looking for a profitable niche in business should pay attention to underdeveloped sector economic activity – recycling of industrial and household waste.

This type of activity involves the collection and processing of a variety of garbage, production waste and used packaging into new products.

Among all types of recyclable materials, used glass containers occupy not last place in terms of the volume of waste that can be reused and make good money from it, since competition in this sector of the Russian economy is minimal.

Recycling glass waste as a business, subject to a competent approach to the entire technological cycle, from the collection of raw materials to the production and sale of finished products, will bring good profits.

The main thing in this matter is a properly developed and implemented business project, which allows you to plan activities and optimize costs and income.

In addition, any enterprise engaged in waste recycling can count on government support and subsidies, since this type of activity improves the ecology of the environment and conserve non-renewable natural resources.

In most regions Russian Federation There are targeted programs to support entrepreneurs involved in waste recycling.

They consist of issuing grants and subsidies to repay part of the interest on loan rates and reduce the tax burden.

Unlike previous years, recycling of usable glass containers has practically disappeared. Most enterprises in Russia package their products in new bottles, cans and other containers.

Therefore, there are no problems with the raw materials. In addition, industry and the construction industry produces large volumes of glass waste that can be recycled.

In such conditions, it would be a sin not to take advantage of the situation and open a profitable business for the production of products from broken glass or simply for subsequent resale.

We will consider the prospects for such a business and the types of products that can be produced from glass waste.

Glass waste is a practically non-degradable material. It takes nature hundreds of years to turn this waste into environmentally friendly silica dust.

Let's consider positive sides processing of glass recyclables into new products.

1. Recycling broken glass is very useful technological process from the point of view of environmental safety. In addition, a reduction in the area occupied by landfills and landfills where glass waste is disposed leads to an increase in the area for the placement of necessary infrastructure facilities.
2. Inorganic mineral glass is made from a mixture of quartz sand (silica), soda (sodium oxide), lime (calcium oxide) and other necessary impurities. Recycling glass waste can dramatically reduce the use of these non-renewable natural resources.
3. Production of finished products from glass fight requires less energy resources and initial mineral raw materials, which leads to savings in natural gas and electricity, and consequently to a reduction in production costs. This increases the competitiveness of finished products.

All these advantages of glass waste recycling allow us to confidently say that this type of activity not only brings good income, but also is a socially useful matter, preserving the environment.

Below we will look at the types of products that can be obtained by processing broken glass.

List of products made from recycled glass

From glass waste you can obtain a huge number of different materials and products that are in demand in the world. modern stage development of industry, construction and other areas of human economic activity.

Below we will briefly look at some types of these products, the production of which can be used to build your own highly profitable business.

1. . This type of heat insulator, produced in blocks and sheets, is in high demand among consumers. The production technology of this material is quite simple and relatively inexpensive. It is based on foaming molten glass followed by cooling in special molds. Initial investments in the production of foam glass from cullet with mineral additives start at 3 million rubles.
2. . The most popular thermal insulation material in the modern building products market. In its production, up to 80% of cullet can be used. The glass wool production technology is based on spraying molten glass in a centrifuge with a jet of steam. A carpet is formed from glass fibers, which is cut into mats, sheets or rolled into rolls. Start-up investments in glass wool production range from 4 million rubles.
3. . The material is intended for waterproofing various construction projects, sealing joints, improving the quality of concrete and other technological operations. In everyday life it is known as silicate glue. The process of producing liquid glass from cullet is based on grinding the waste with alkali metal hydroxide in an autoclave. Read here about the production and applications of this material. The initial investment in organizing a small production will be at least 2 million rubles.
4. Glass container. The secondary production of glass containers from broken glass is a complex technological process. In addition to smelting furnaces and various equipment To prepare the charge, you need to purchase an automatic molding line with equipment. The amount of broken glass in the feedstock can reach 100%. Read about making glass containers from recycled materials in this article. To implement the project for the production of glass containers from waste, it is necessary to spend at least 100 million rubles.
5. . High-quality and beautiful finishing material. Glass tiles are made from a mixture of finely crushed broken glass, dyes and special polyester resins, which is poured into molds to harden. The maximum amount required to open a small artisanal workshop for the production of tiles from broken glass is unlikely to exceed 500 thousand rubles. Investments in such a business are minimal, and you can get good profits. Here you will find more information about making glass tiles.
6. . Used in the production of fiberglass and other popular materials. fiberglass is based on pressing molten glass through special platinum dies, followed by cooling and winding an endless thread onto receiving drums. Up to 45% broken glass can be used in the production of the product. A small fiberglass production enterprise will cost at least 6 million rubles.

Production of all of the above products from glass waste requires a large initial investment for the purchase of equipment, rental of premises, organization of the purchase of recyclable materials and other technological needs.

But there is also a simpler type of glass business - this is the opening of a collection point for glass containers and broken glass from the population and organizations.

Below we will look at the stages of creating such an enterprise and its profitability.

How to open a glass collection point?

Opening a collection point for glass containers and broken glass is the first step in mastering the glass waste recycling business, of course, if you intend to develop your activity to deep recycling of this recyclable material to obtain final marketable products.

Otherwise, you can stop at the first stage - collection and primary sorting of waste and make a good profit from the sale of bottles, cans and waste.

But for this it is necessary to open a collection point for glass recyclables and containers.

The procedure for opening such a business is quite simple and it is performed according to the following scheme:

• Initially, a business plan for opening a collection point is worked out in detail, determining the optimal location, possibilities for selling glass containers and broken glass, as well as the approximate profitability of the enterprise;
• at the next stage, it is necessary to open an individual entrepreneur or LLC for this type of activity with the preparation of all the necessary documentation and registration with the territorial tax authorities;
• subsequently rented and repaired in accordance with general requirements premises for a collection point, the necessary equipment is purchased (boxes, containers, etc.) and you can start working.

Economic activities for the reception of glass containers and broken glass not subject to licensing. It is only necessary to obtain permission to use the rented premises for this type of business from the SES and the fire inspectorate.

As mentioned above, currently only a small amount of bottles are reused.

Basically, all accepted glass containers are sold to large wholesalers at the price of broken glass, with the exception of jars that are purchased for subsequent recycling.

But even with such seeming business failure you can get a good profit of 30%, because bottles are purchased at prices ranging from 50 k. to 1 r. per piece, and broken glass is sold at a price of up to 2.5 thousand rubles per ton!

Video on the topic

This video explains why glass recycling is necessary and how it is done.

Conclusion

For the Russian Federation, the level of competition in the business of collecting and processing waste glass is extremely low, so if you open an enterprise only for receiving, crushing, sorting and selling raw materials to interested manufacturers, You can achieve profitability of up to 80%.

Recycled glass can be purchased through a network of collection points, stored at landfills and landfills, and also purchased from glass factories for manufacturing defects at an affordable price.

Increase profitability own business processing of scrap glass is possible by expanding production to deep processing of glass into finished products. We have given a list of such products, the most promising in terms of demand and price, above.

Of course, complete recycling of broken glass into building materials and other products will require a large initial investment, but this approach to developing your own business will provide you with a constant and high income for a long time.

There are quite a few half-liter glass jars accumulated at home. Firstly, it’s a shame to throw them away, and secondly, it’s dangerous and harmful to the environment. Therefore, an interesting idea came to my mind - to try to somehow melt glass and play with glassblowing. As I understand it, the glass in jars is SiO2, which needs a non-acidic temperature to melt. But at home it is unlikely that you will be able to heat anything by more than 300 - 400.
In general, I think in this direction and am ready to hear your thoughts.

I once played at the dacha, temperatures needed to reach 1000 and above.
In addition, glass is amorphous, it will not become liquid :) (at the temperatures and additives available to you, certainly). It smoothly softens and becomes like thick resin/gummy - viscous, sticky, and terribly out of control :)
It was funny to wet a stick and pull a long 2-meter “snot”, which quickly cooled, cracked and crumbled from internal stress.

In general, it’s fun to play around, but you won’t get anything useful.

Find where these banks are accepted and return them, receiving 3 kopecks and a feeling of moral satisfaction for your contribution to the preservation of nature.

I melted in a stove, but in this stove I melted zinc, aluminum, and burned copper. but it was impossible to pour out anything (except for zinc, it is relatively fusible) it is very difficult to make a crucible that will withstand this, and when the aluminum was taken out of the furnace it began to boil strangely, it probably burned in the air, it was not poured into the mold but it made drops.
I melted a brown glass vitamin jar, it stretched into snot and then fell into the oven. I couldn’t get it back, I think it’s not realistic to pour it into a mold, it needs to be more liquid, unless pressed. I haven’t tried to blow, I have nothing.
I think the melting point (although it’s more likely not melting but softening) is somewhere around 500-600 degrees

How to make money from broken glass

Today, not many people know that the old glass container collection points brought considerable income to their owners. But new times dictate new conditions for doing business. Today, each manufacturer's glass containers are original, and therefore there is no point in collecting whole bottles, but broken ones are available. The thing is that the technology for producing glass for bottles does not change and remains quite expensive. But if you melt ready-made glass (shards of broken glassware), you can significantly reduce the cost of producing the final product at glass factories. So how? make money from broken glass individual entrepreneurs?

The fact that you can make good money in the niche of broken glass was proven by Nizhny Novgorod resident Andrey Shamaev. He took out a loan and purchased the necessary equipment - several machines for removing broken glass and equipment for processing and cleaning such waste. Two hundred thousand dollars borrowed from Sberbank was enough for storage space and recycling of cullet. A few years later, the profit of the company organized by the young entrepreneur.

The entire glass recycling process: recycling as a way to preserve nature and earn money

covered the invested amount seven times. Which, however, is not surprising - after all, money is literally lying under your feet.

So, how can you make money from cullet (broken glass)

First of all, it is necessary to find a suitable area for a warehouse, where not only the storage of collected cullet will be carried out, but also the preliminary sorting and processing of broken glassware. If you can find such a warehouse close to transport routes, then you can also locate it here. cullet collection point.

Where can I get broken glass and who can act as distributors or suppliers of this recyclable material? In addition to the completely predictable contingent such as homeless people and other socially disadvantaged groups, there is another group of collectors - janitors, who can also collect broken glass well. As the glass accumulates, they will inform you and you will only have to load and remove the broken glass.

In addition, you should definitely negotiate with window installation companies. For a small fee, they will give you glass from dismantled old frames. Not everyone keeps them; in most cases, old window frames have only one way - to the trash heap.

Another promising way is to try to negotiate with the authorities of your city to install additional special containers intended for glass only. ABOUT separate collection Everyone talks about garbage now, but, unfortunately, few people do anything about it. Even Andrei Shamaev failed to come to an agreement with the authorities of his city. But trying is not torture.

There are also restaurants and other catering establishments. In addition, you can go to different parts of the city once a week and collect broken glass. The main thing is to advertise. Soon you will be collecting fragments and waiting for you to pick them up.

In general, collecting broken glass is not a problem. In this business, the most important thing is to find sales for recyclable materials. The situation here is also quite good. Almost all factories that work with glass will be willing to take it from you. True, they accept such raw materials in opened and pure form, therefore, after receiving cullet, you need to wash and sort the broken glass. There is specialized equipment for this.

Summing up, I would like to say that this is a really good, promising business. Factories that produce glass containers will be happy to accept your broken glass. This niche is not even half filled.

Recycling or recycling glass at home.

Recently, food manufacturers have been striving to make packaging design more vibrant and attractive, the same applies to glass containers. Naturally, unusual and bizarre shapes of glass bottles are not in demand at glass collection points. Therefore, more than 90% of glass bottles end up in landfills.

Main stages of organizing glass processing

First, used glass containers are collected from landfills or collection points for any glass are set up. Also, special bins for glass containers are often organized. After collecting used glass, it is cleared of labels. The last step in this process is to crush the glass using crushing equipment.

Products made from recycled glass can be reused and are in no way inferior to traditional glass, as recycling does not change the structural properties.

Benefits of glass recycling

Another advantage of glass recycling is waste-free production. Nowadays, a modern promising entrepreneur strives for environmentally friendly production and cost savings. Therefore, glass recycling can be a good idea for business development. In Russia, this niche of entrepreneurship is still practically unoccupied, but in Europe there is already high competition between firms, and they, in turn, bring high incomes to their owners.

Applications of recycled glass

Recycled glass has a fairly large market. The following companies are usually interested in it:

• manufacturers of building materials, namely glass structures;
• manufacturers of ceramic sanitary ware, water filters, insulating and abrasive materials;
• brick manufacturers.

Today there is a large number of modern and powerful crushing equipment for glass processing. They differ in power, performance and other technical parameters. Depending on the volume of production, you can complete the glass processing line yourself.

LLC Tula Machines for glass grinding with simultaneous drying with hot gases offers airborne mills.

The first products from this material began to be made in Egypt 5 thousand years ago - we are talking about the most ancient faience jewelry and figurines. The Berlin Museum still houses a green glass bead, the diameter of which is about 9 millimeters - this is one of the most ancient monuments of glassmaking. Scientists suggest that its age is more than five and a half thousand years.

Glass is one of the most ancient and universal materials, without which it is difficult to imagine modern life person.

Mikhail Lomonosov began a scientific approach to the study of glass: the scientist actively experimented with glass melting technology. It is important to note that the methods used by Lomonosov are not much different from modern classical approaches to the study of this material.

Properties and chemical composition of glass

The chemical resistance of a material depends on its composition: glass containing a small amount of alkali oxides exhibits greater resistance.

Basic physical properties glass:

• strength - compressive strength is 500-2000 MPa;
• fragility - refers to ideally fragile materials;
• Density varies and depends on the composition of the material.

  Recycling glass bottles and jars into new ones

  The density of quartz glass is 2200 kg/m3;

• hardness - depends on the amount of impurities. The hardest is quartz glass, the least hard is lead glass;
• melting temperature - for silicate glass it is approximately 425-600°C. With more high temperature glass turns into liquid.

Today, glass is the best packaging material not only for food, but also for medicines, reagents, various drinks, sauces, etc. However, the negative side of this material is that it takes a very long time to decompose.

What is the danger of glass for the environment if it is simply thrown into a landfill?

1. The decay period of an ordinary glass bottle is 1,000,000 years. Just imagine: our descendants will be able to find an entire bottle of lemonade preserved over such a long period of time.
2. One of the characteristics of this material is fragility - this makes glass dangerous for both animals and humans - everyone knows how dangerous broken glass scattered in the coastal zone or in water bodies can be.
3. Glass located in the soil layer or on the surface is an obstacle to the growth of plants, as well as for small animals.
4. Every 10% of cullet reduces gas consumption by 3%. That is, if a glazier uses only broken glass to produce his products, then the gas consumption for the manufacture of products will decrease by 30%.
5. In our country, glass recycling annually saves more than 10,000 hectares of land that could otherwise become landfills.

That is why the problem of large-scale and timely processing of this material does not lose its relevance to this day.

Let's talk about the benefits of glass recycling

• glass is a 100% recyclable material - thus, after its processing there are no by-products left that negatively affect the environment;
• Every 1000 kg of recycled waste saves more than 1000 kg natural materials, including 200 kg of limestone, about 180 kg of soda and more than 600 kg of sand;
• You can earn additional money by delivering material to glass container collection points.

Main types of waste

1. Glass containers: glass bottles and jars. Many people, wanting to recycle glass, collect it and take it to collection points, for which they receive small money. Next, the glass containers are thoroughly washed and disinfected, and they can again be used for food packaging.

2. Glass breaker - as the name implies, we are talking about broken glass. There is hardly a person who has never broken a glass product. However, cullet, just like glass containers, can and even should be recycled.

Cullet is usually classified by color:

• PST - semi-white container glass;
• ZS - green;
• BS - colorless;
• PSL - semi-white sheet;
• KS - brown;
• SS - mixed.

In our country, separate waste collection is almost never practiced; no more than 35-40% of cullet is recycled. Enterprises specializing in its production need recycled glass. Today, there are more than 120 manufacturers of products made from this material in our country.

One of the main areas in which cullet is used is the production of containers (bottles and cans). In this case, minimally stringent requirements are put forward for the composition of the glass melt, which allows the use of materials of different composition and color. Also, cullet is often used for the production of various foam materials, for example, foam glass, which is an indispensable material in modern construction.

Products made from glass are powerful heat insulators, so they are often used for insulating pipelines, producing modern sandwich panels, as well as for insulating roofs, external walls, ceilings, etc.

Due to their performance properties, glass-crystalline materials are in great demand in the construction industry. During their production, cullet and glass waste are often used. Unlike other materials, which are also used in the finishing of buildings, glass-crystalline materials are characterized by durability, almost zero water absorption, high strength and abrasion resistance.

How is cullet collected?

Recently, glass packaging for various drinks has become increasingly popular; the amount of cullet in Russia has increased significantly. Domestic ecologists cite the following facts:

• Every year about 150,000 tons of glass waste are generated in our country;
• The volume of glass waste collection is about 57,000 tons per year (38% of the total waste volume).

Foreign countries have accumulated extensive experience in collecting cullet, which Russian specialists are gradually adopting. In the West, specialized enterprises collect glass waste. In America, glass companies set up special collection points where people bring broken glass and glass containers and where primary waste processing takes place.

In our country, special containers are installed on the streets to collect cullet, into which people throw waste. Also, along with stationary collection of glass waste, mobile collection is also used - it includes regular visits to houses, private and public enterprises.

In Europe, one of the most popular and budget ways is to organize mobile units reception, where glass waste is collected, sorted and subsequently crushed.

How much can you earn from recycling?

Today in Russia there is an opportunity to make good money by disposing of glass waste. On average, the cost of a ton of cullet is approximately 40-45 US dollars at the current exchange rate, about 2500-3000 rubles.

Unlike cullet, which can only be sold in large quantities, glass containers can be returned even in the amount of one bottle at any collection point. Behind glass bottle you will receive from 50 kopecks to several rubles - depending on its volume, neck and glass color.

How is cullet processed?

The glass processing technology is carried out as follows: first, the glass cullet is sorted by color, garbage and various mechanical impurities are removed, the waste is thoroughly washed and crushed.

Most often, sorting is done manually, but sometimes special equipment is used. The MikroSort installation, manufactured by the German company Mogensen GmbH, is popular.

Mechanical impurities are removed in the following way:

• a magnetic separator is used to extract metal inclusions;
• ceramics, various metals, etc. are separated from the total mass using screening installations.

Metal and color separators are also used - they separate impurities containing certain metals, as well as inclusions of a certain color. An example of such an installation is S+S Separation and Sorting Technology GMBH (German production).

The use of glass recycling equipment depends on what is needed after the job is completed. To produce recyclable materials, there is no need to use crushing plants, and specialists carry out the destruction of glass waste manually. In order to crush cullet into fractions of the required size, it is necessary to use special crushing equipment - on the modern market you can choose from a variety of both foreign installations and Russian-made equipment.

The service life of the equipment used for processing waste glass depends on the size of the debris supplied to the input, as well as on the size that should be obtained at the output. If a fraction of about 300 millimeters in size is supplied to the input, and the result should be a piece of 50 millimeters, then the crushing process consists of several steps. Experts say that 7-8-fold crushing is optimal.

When recycling glass waste, it is preferable to use those technologies that do not negatively affect the state of our nature and also do not require large energy costs. This is why modern processing systems based on filtration and subsequent melting of glass using innovative “gas” technology have gained popularity.

The resulting glass mass is used to produce materials used in construction, double-glazed windows, glass for windows, glass blocks, insulating materials and other types of products.

Proper disposal of glass waste helps keep our planet clean, and reusing glass containers is the most optimal way of recycling. Unlike plastic containers, glass packaging can be washed, thoroughly disinfected and reused. However, due to the fact that one of the properties of glass is fragility, it is the cullet that turns into waste, which requires not only timely, but also competent disposal.

Our history is moving in a spiral: if a few decades ago people were forced to fashion everything disposable, now this approach has proven its failure. Now we understand that in order to save our planet, we need to reuse household items.

Let's save nature together! Take glass containers to a collection point and help improve the environmental situation on Earth!
