Cost of recycling passenger and studded tires

You pay to transport the old tires to the recycling plant. Worn studded tires are a separate case. Technologically, it is more difficult to recycle it, so factories treat such tires with caution, to say the least. And the cost of disposal is more expensive, since manual labor is also partially used here.

The problem of recycling used tires is acute in many countries. In this matter, not only the environmental aspect is important, but also the economic one, because the material obtained during processing is a good raw material for the chemical industry. Let's find out what processing methods are currently used in the world, how effective and safe they are.

Types of recycling of used tires can be divided into two groups:

• electromechanical grinding;
• processing that changes the chemical structure.

Tire processing using these methods differs in the principle of operation and the resulting raw materials. Each of them has its own advantages and disadvantages, which are worth talking about in more detail.

Mechanical tire shredding

This method is considered relatively safe from an environmental point of view and is widely used throughout the world. Tires are subjected to the following processing:

1. Old tires are washed, the beads are removed and cut into large pieces.
2. Raw materials are cleaned from steel cord using magnetic separation.
3. The pieces are then heated (for elevated temperature processing) or cooled (for cryogenic processing).
4. Rubber is crushed by cutting, impact, explosion, compression or abrasion.
5. The resulting raw material is ground to obtain crumbs of the desired size.

The disadvantage of this method is the high cost of the final product, since tire shredding requires special equipment and is considered an expensive processing method. Electricity costs are also high - up to 1000 kWh per 1 ton of processed raw materials.

At the same time, shredding has significant advantages over chemical methods of tire processing: technical simplicity, lack of toxic emissions (unlike combustion or pyrolysis). Rubber processing by grinding preserves the technological parameters of the material.

Crumb rubber obtained by grinding is widely used in industry and construction: for the manufacture of household products, additives in mortar, and for laying roads.

The following video shows how tires are processed into crumb rubber and what equipment is used.

Other Tire Shredding Methods

There are other methods for shredding old tires, but for various reasons many of them are not widely used. The most well-known processing methods:

• using a rotary disperser;
• ozone knife method;
• barodestruction method;
• shock wave grinding (explosive circular).

For the rotary disperser, the tire is crushed into small pieces. The rubber is then compressed in the sleeve and passed through a hole with a diameter of about 1 mm. The result is fine rubber dust with a highly developed surface that can effectively react with other components of the mixtures. Such dust is used for the manufacture of sorbents, new tires, roofing materials, etc.

Tire recycling using the ozone knife method involves exposing worn rubber to ozone in a special chamber and subsequent mechanical grinding. Ozone promotes the destruction of the rubber structure, facilitating further grinding of the tire by mechanical methods. As a result, pure rubber crumb and metal are obtained from the old tire, and there is no need for separation, since the metal and rubber themselves separate from each other when exposed to ozone.

When treated with the barodestruction method, tires are first cut and crushed, and then in a special chamber, under the influence of high pressure and temperature, the rubber is brought to fluidity, separating it from the metal cord. The result is fine rubber crumbs with a granule size of about 0.8 cm.

Processing methods that change the chemical structure

Recycling of car tires, which changes the structure, is also not very profitable. The rubber component disappears after processing, and the resulting product has a lower cost than in the case of mechanical processing. At the same time, the cost of final raw materials is quite high.

Among the chemical methods for recycling tires, the most common are the following:

• pyrolysis;
• thermal destruction (combustion);
• dissolution.

Pyrolysis is a thermal decomposition that occurs in a special chamber without air access. This method is most often used to obtain thermal energy. Rubber processing by combustion and pyrolysis has a number of limitations; they are associated with the release of carbon dioxide and toxic substances. This method requires more attention from an environmental point of view.

When burned in cement kilns, tires replace combustible materials such as coal and fuel oil. This method is used in the cement industry and to generate heat.

Many experts consider the dissolution of old tires to be a promising and very effective method, although it has not yet been widely used. Under the influence of the solvent, raw materials are obtained that can be successfully used in metallurgy and the chemical industry.

It is expected that this technology will help to effectively recycle tires of all types and sizes in the future.

Tire recycling in Russia and Europe

European countries boast recycling rates of old tires reaching 90%. About 20% of them are recovered and reused, 40% is used to generate heat, and more than 30% turns into crumbs.

Unfortunately, the global average is not that high - less than 40% of tires are recycled, and 60% of unrecycled rubber goes to landfill.

Important! Every year, about 10 million tons of new waste from old car tires appear in the world, which makes the environmental situation simply catastrophic. It is very important to pay close attention to this problem and introduce recycling methods in countries where it is not developed.

In Russia the situation is completely sad, although it is gradually improving year by year. Tire recycling currently accounts for about 10%, and has grown by a quarter over the past few years. Tire recycling organizations in Russia are not yet very active; in our country, people are not used to investing money in secondary production, disposal and recycling.

One of the additional problems is that it is more difficult to recycle domestically produced tires, common in Russia, Belarus and other neighboring countries, than European ones. Our old tires are additionally reinforced with radial synthetic cord, and a large admixture of textiles creates great difficulties for processing. As a result, processing domestic tires is much more expensive and more difficult than Western-made tires with an all-metal cord type.

Additional Information! The most common processing methods in Russia are crushing and pyrolysis. It should be noted that pyrolysis is prohibited in some developed countries due to its harmful effects on the environment. However, domestic entrepreneurs consider more expensive processing methods to be too expensive, so they use them much less frequently.

We hand over rubber for recycling

However, there is still reason for optimism - over the past few years, new environmentally friendly and safe complexes for the production of crumb rubber have appeared in Russia. In particular, such complexes operate in Samara, Kursk, Tver, and Vyazma. A processing center was built in Primorye, and a franchise helped many enterprises operating in this industry launch production.

Almost every major automobile service center in Russia accepts old tires from car enthusiasts. You often have to pay extra to return tires, although some services accept them for free. Companies are increasingly entering into contracts with recycling companies, handing over significant volumes of old rubber for recycling.

You can hand over tires for recycling at factories and complexes that produce secondary raw materials, as well as at car service stations. It is worth considering that large enterprises usually do not accept tires from the population due to the small volume of the product being handed over, so citizens have to monitor promotions at car service stations in order to get rid of one or two sets of tires.

Economics and ecology

The economic benefits of recycling tires are undeniable. In a number of countries, flammable gas, which is released during the heat treatment of tires, is used to heat rooms, and it is also used to generate electricity. Liquid pyrolysis products are used in the production of plastic, and crushed rubber particles are an excellent raw material for asphalt bitumen.

Note! The decomposition of tires in the ground continues for more than 100 years, all this time dangerous and toxic compounds, such as phenanthrene, diphenylamine and many others, are constantly being washed out of old tires. All of them remain in the soil and are then washed away by groundwater and rainfall, ending up in drinking water sources and agricultural facilities.

Thus, in the coming years, tire recycling methods will be improved, and the volume of rubber recycling will grow. This is especially true for developed countries, where environmental issues and recycling of materials have long been under the close attention of both citizens and authorities.

The situation in Russia is still reminiscent of the situation in African countries, but the principles of responsible consumption are gradually penetrating the consciousness of our citizens. In a few decades, both car enthusiasts themselves and business representatives will know exactly what and how to do with old tires in order to get the maximum benefit from them for themselves and the environment.

There are more than 1.1 billion passenger cars in the world. The number of registered cars in Russia is about 46 million. This means that if we add trucks, then there are about 5 billion tires running on the roads of the world. The number of tires in landfills around the world is unknown. In Russia, according to various estimates, from 30 to 45 million tires are thrown away per year. There is no need to talk about the harm that such waste causes to the environment.

The issue of recycling and disposal of car tires is acute throughout the world.

There is not a single country in which this problem is considered solved. In our country, according to various sources, from 8 to 12% of old tires and conveyor belts are recycled. These figures indicate that tire recycling as a business has good prospects.

However, having decided to run a rubber processing business, you must carefully choose the processing method and imagine all the pitfalls of such a business. Choosing a processing method, and therefore the direction of your investment, is a very complex task. Enterprises that produce equipment for one or another processing method naturally praise their method and carefully hide its shortcomings. In this article we will try to make the task of choosing a processing method easier. Remember that there is no perfect method. Everyone has flaws. Here are the main ways to recycle car tires:

• reuse by applying a new tread (in this case, after reuse, the tire still needs to be recycled);
• combustion to produce thermal energy;
• heating without air access or with limited air access (pyrolysis);
• grinding to produce crumb rubber, recycled metal and textile threads;
• burial and use for strengthening the coastline, installing fences, etc. This method is prohibited in most countries, including Russia. We will not consider it.

We do not consider in this article applying new tread to worn tires (“welding”). This is a method of extending the life of tires rather than recycling them. But let's look at other methods in more detail. When evaluating recycling options, you should have a basic knowledge of the tire material composition.

Tire material composition

The main components of tires are cord (metal, textile or mixed), rubber, filler (soot), auxiliary materials (thermal stabilizers, anti-ozonators, etc.), adhesives (contain polychlorinated hydrocarbons and some other materials in small quantities. If we do not consider metal cord (which is a steel wire coated with brass - an alloy of copper and zinc), then the composition of the tires includes: hydrocarbons (rubber, etc.), carbon (soot), silicon dioxide, sulfur (vulcanizing agent in rubber and other components), polychlorides (in adhesives) and some other components in small quantities. Contrary to popular belief about the presence of arsenic in tires, it is not there. Heavy metals are also absent (except for a small amount of copper and zinc on the surface of the steel cord). Lead is also not used in modern tires. All these components undergo changes during tire processing and form new substances, many of which are more dangerous than the original ones. Now let's look at the advantages and disadvantages of various tire recycling methods.

Burning tires to produce thermal energy

The method seems attractive. Therefore, it is worth talking about it in more detail.

Burning one ton of tires produces approximately the same amount of thermal energy as one ton of thermal coal.

What is the problem? Firstly, tires cannot be burned in conventional thermal power plants. You need special equipment and preparation of raw materials. Secondly, when sulfur is burned, it produces large amounts of sulfur dioxide (sulfur dioxide). This requires a special cleaning installation. The problem is being solved, but the equipment is very expensive. Thirdly, polychlorides at insufficient combustion temperatures form one of the most dangerous substances - dioxin. Available international experience indicates that this method has the right to life only when processing very large quantities (more than 100 tons) per day, requires huge capital investments and is profitable only in the case of subsidies (financial support) from the state.

Tire pyrolysis

The process involves heating the material to 400–500 degrees without access to oxygen (air). This produces pyrolysis gas, a liquid hydrocarbon fraction, soot and steel cord waste. You can find excellent product costing. For example, from 1 ton of tires you can get 500 kg of liquid hydrocarbon fraction (fuel and even gasoline!), 200 kg of gas (used to heat the reactor and save fuel), 200 kg of carbon black and 100 kg of metal. What's the problem? Ask yourself a question: where does sulfur disappear if it contains up to 10% silicon dioxide? Very simple. Most of the sulfur turns into hydrogen sulfide (the strongest poison, a substance of hazard class 1), which is contained in pyrolysis gases. The other part of the sulfur forms carbon disulfide and other compounds, which go into the liquid fraction. And finally, the residue, which is bashfully called carbon black, contains metal sulfides (mainly sodium and calcium). Where did the silicon dioxide disappear - into the residue. The fate of polychlorides is even more complex. Some of them go into the residue, some form hydrogen chloride (not a gift!), and some form dioxins, which can be found in all products. This “carbon black” will not be used by any responsible consumer. You can't bury it either. By recycling tires in this way, we will create a bunch of new problems. These problems can be solved, but require large capital investments, which calls into question the profitability of this method without government assistance.

Grinding tires to obtain rubber crumbs

The essence of the method is very simple. Tires are shredded. In this case, three products are formed - metal, crumb rubber (we will consider the directions of its use below) and textile cord waste.

With such processing, virtually no chemical changes occur (no new toxic waste is generated).

This is the main advantage of the method. What are the problems? It is very difficult to separate textile threads from crumb rubber and the textile material thus obtained is practically a new waste. We will further show how this problem can be solved. But at the initial stages it is better to start processing purely steel-cord tires. This will significantly reduce capital costs. The key problems when constructing a mini-tire recycling plant are the following problems.

1. Choosing a location for production. Construction or use of existing structures.
2. Selection, purchase and installation of equipment.
3. Obtaining a processing license.
4. Formation of reliable channels for obtaining raw materials and marketing finished products.

Let's look at everything in order.

Production site and buildings

Even a mini-tire recycling plant requires a fairly large site. Most of the production site will be occupied by a warehouse for raw materials (tires) and finished products. The tire recycling line occupies a fairly large area - 150–300 m2. It is better to clarify this after choosing the equipment. The height of the building (or hangar) is 5–6 meters. The production site must be sufficiently remote from residential buildings. Minimum distance 200-500 m. The best place is an industrial zone. When recycling tires, the material heats up quite strongly and releases volatile substances with a specific odor. Local ventilation is required. It is necessary to provide special absorption cartridges as part of the ventilation equipment. They are produced industrially.

Equipment for processing tires into crumbs

For processing tires into crumbs, the price of equipment is not prohibitive. However, the cost of a set of equipment of 10–15 million rubles should be considered minimal. The choice of equipment for processing tires into crumbs is quite wide. There are Russian-made and imported lines. When choosing equipment, don’t pay too much attention to brands.

Tire recycling line

If possible, visit an existing production facility and listen to all about the problems of this production. When purchasing equipment, it is better to focus on complete lines, but some components can be used or purchased separately. Here is the minimum list of equipment:

• shredders (shredder, hydraulic shears, tape cutter);
• separators (air and magnetic);
• conveyors;
• vibrating screens

Has anyone ever thought about what to do with old tires that are no longer needed and have nowhere to be used? Today, the environmental issue is very acute, and materials such as rubber take several hundred years to decompose, which causes irreparable harm to our planet. So what to do with old wheels and how to solve this problem?

Where to put old tires?

Before answering the main question of this article, it is worth understanding what rubber is, why you need to think about how it can be recycled, and how it can harm.

In order for a car to move and drive on the road, it needs wheels, the main element of which is car tires, consisting of several parts:

• sidewall;
• tread;
• cushion layer;
• side part;
• frame.

The main materials used for wheels are rubber and cord (special fabric or metal consisting of strong longitudinal and transverse threads).

Every year, car enthusiasts, car repair shops and service stations are faced with the problem of where to return old tires for money or free of charge, so as not to harm the environment. After all, everyone knows that rubber takes more than 100 years to decompose, and tire landfills occupy huge areas. If you burn rubber, then during combustion it releases toxic substances that enter the air that people breathe, creating a vicious circle.

Not so long ago, people began to wonder whether tires could be given a second life and what could be made from them. After all, there are factories for recycling paper, metal, old unwanted clothes and plastic.

Reception of old tires

Every major city today has collection points for car tires, which are then transported to a specially created landfill or for recycling.

For example, in Moscow there are no more than 10 such places, since this area of ​​recycling is just developing. You can take them to the address: Beregovoy Proezd, 3 to the company "Auto Legion" or to Yuzhnoportovaya Street, 7 to the company "Shinservice". There are also several points in other millionaire cities.

If in Europe you can bring car tires and they will pay you, then in Russia you will not be able to find the answer to the question of where to sell old tires for money, or you will receive a minimum amount of 100 rubles. for one wheel.

The innovation of recycling began to be introduced not so long ago, and the state has not yet established a rule at the legislative level that every motorist must hand over tires after using them, and rubber collection centers do not operate on a permanent basis.

Disposal methods

How can you use old wheels in the future, if not to create a flower bed out of them? There are several ways to recycle old tires, and the most popular of them is crushing the rubber and turning it into crumbs. The transformation can be carried out in two ways: the first using high temperature, the second - using cryotechnology, the essence of which is to create a fine-grained powder while maintaining the chemical composition of the material.

Once the raw material is processed, it can be used, for example, in roofing materials or car mats. There are a lot of options, but many have not yet been implemented, which has a bad impact on the environment.

What to do next

After old tires are recycled, crumb rubber is obtained, which is used in several types of production:

• rubberized asphalt;
• flooring, for example in gyms or playgrounds;
• running and walking areas;
• building materials.

Options for use on the farm

Probably everyone can imagine what flower beds made from old tires look like. This is a creative way to decorate your garden, and you can get the wheels completely free.

But if you don’t use them to create a beautiful garden, then there are other options for using them on the farm:

• for example, you can make a mini-pool from rubber for children or even for adults, depending on the size of the wheel. Or use it as a barrel where water will be stored, because rubber is a durable and flexible material that lasts for many years;
• the second option is to create an unusual swing, many have seen such examples more than once;
• someone even creates an unusual chair and does not ask the question of where to put the old tires, but simply uses imagination, thereby protecting nature.

The list of options for using car tires can go on for a long time: flower beds, a small table, swings, ottomans, an armchair, interior decoration and much more.

Is it possible to create a processing plant?

Every year, scientists estimate that more than 3 billion tires are thrown away as used goods. Based on this, we can conclude that a tire recycling plant is a very promising business, which will also help save the environment.

In Russia today there are only two factories, their operating capacity is 40 thousand tons per year, and of course, this is not at all enough.

The main advantage of such a business is that the material can be obtained completely free of charge, and the resulting crumb rubber can be resold for further production. The niche of this business is free, and there are almost no competitors. But why doesn’t anyone strive to make money in this direction?

Disadvantages of business:

• large initial investment;
• it is necessary to select raw materials with the same chemical composition.

Difficulties arise not only with this, but also with the fact that you need to find a large room that will be removed from the living area. You need to officially register your activities and collect the necessary package of documents, including obtaining an opinion from the sanitary and epidemiological service. The next stage is the purchase of equipment and personnel selection, and according to the preliminary business plan, this activity can pay for itself in 8 months.

But what risks might there be:

• interruptions in the supply of raw materials;
• problems with the sale of material;
• breakdown of technical equipment.

It has been said several times that rubber is a material that takes decades to decompose and is harmful to the environment. But not everyone knows that to get one tire you need to spend more than 30 liters of gasoline.

What other facts are there about this product?

• Every year, more than 5 tons of tires become unusable and only 20% are recycled.
• But if you recycle one ton of tires, you can get half a ton of material, from which you can then make new wheels.
• The Russian authorities do not yet care about creating many collection points and building recycling plants, as a result of which tires end up in a regular landfill, which leads to environmental pollution.

After reading the material, perhaps many will no longer have the question of what to do with old tires. Everyone will think about how to save nature and our planet from environmental disaster, and will take used wheels to delivery points where car tires can get a second life.

DEAR COMPATRIOTS!!!

Due to numerous requests, we inform you that in the Central region of Russia, NOBODY is yet paying Customers for used tires handed over for RECYCLING, including our company!!! If you consider them suitable for further use, then do not apply the term recycling to them!

Tire recycling in Moscow. Recycling of tires.

The Inter Green group of companies provides a range of services for the collection, transportation, processing and sale of products obtained from waste tires.

Our financial conditions for the acceptance and disposal of tires:

The location of the waste tire collection point at a considerable distance from the processing complex, as well as the imperfection of the legislative framework, makes it impossible to compensate for their disposal. You can calculate the cost of recycling tires based on their total quantity. It is about 2000-3000 rubles per ton. You can make payment by bank transfer.

Where to donate old car tires?

Waste disposal occurs with the provision of all necessary documents - environmental acts, financial ones.

Disposal of tires is carried out on the basis of the Federal Law “On Production and Consumption Waste”. This protects enterprises from possible sanctions and exorbitant fines from government executive bodies for their unauthorized placement.

The tire collection point is open on weekdays. Disposal of tires is accompanied by determination of the quantity, as well as the exact weight. Reception of waste tires is carried out according to the weight table. The diameter of the tires themselves determines their weight. We accept used car tires on weekdays. Also, control weighing is always carried out in the presence of the Client.

We accept old tires using the technologies we use for storing tires before disposal (see photo), which have been tested by many years of practice. We will be happy to tell your specialists how to use them. This will significantly reduce the space used for the accumulation of waste tires at the enterprise.

Contact our company to get all the answers to the question - rubber recycling.

The growing vehicle fleet in the modern world entails an increase in the number of used tires. Disposal of car tires always requires regularity, for these reasons:

Waste tires are a strong source of long-term environmental pollution; their untimely disposal leads to a decrease in the standard of living of us. Tire piles are often home to countless hordes of rodents. For these reasons, the use of car tires is becoming very relevant today.

There are many methods, the use of which can be successfully described as recycling tires or recycling rubber goods. For example, they are used to make:

• Sports surfaces - parts of a football field, tennis courts or playgrounds;
• New car tires by partially adding crumb rubber,
• Rubber products with partial use of a processed product,
• Specialized roof coverings directly from crumb rubber,
• Railway sleepers and rail pads made of compressed rubber,
• Construction of road surfaces by adding the resulting rubber to asphalt;
• Decorative tiles made from rubber crumbs using vulcanization.
• Production of crumb rubber (a very valuable raw material for making rubber coatings)
• Fuel oil produced by pyrolysis serves as an excellent source of heating.

You can hand over your tires to our waste tire collection point by simply calling our company.
