More than 80 billion tons of solid waste has accumulated in Russia.

Waste is money, not a problem

We are accustomed to living, thoughtlessly believing that the air will always be clean, and the water in the tap can always be drunk without harm to health. We take out garbage in containers or just throw it on the sidewalks (and sometimes on lawns), naively believing that all this plastic, glass, paper, metals, rags - all this will disappear somewhere by itself.

Indeed, many household waste - wood, textiles, grass, leaves - are utilized by microorganisms. However, in the process of his development, man has created many synthetic chemicals that do not occur in nature and, therefore, are not capable of undergoing natural decomposition. Plastic, for example, currently accounts for up to 8% of the weight and 30% of the volume of packaging materials. At the same time, the absolute amount of plastic waste in developed countries doubles every ten years. In addition to plastic, more than 10 thousand new chemicals are synthesized every year in the world, and most of them, after they become unnecessary, can have an adverse effect on nature for many years. Unfortunately, manufacturers, having created a new product, are not responsible for what will become of it after it has served its term (V. Bylinsky. Garbage disaster / World of news. - January, 2005. No. 2 (576)).

If we talk about Russia as a whole, then every year about 7 billion tons of all types of waste are generated on the territory of the country. By now, only about 80 billion tons of solid household waste have been accumulated. And according to experts, in 2.5 years the volume of garbage generated in large cities may double.

Of the total waste mass, about 9 million tons of waste paper, 1.5 million tons of ferrous and non-ferrous metals, 2 million tons of polymeric materials, 10 million tons of food waste, 0.5 million tons of glass are buried annually in the country ... In other words, waste is destroyed , which are potential secondary raw materials (paper, glass, metal, polymers, textiles, etc.) In this sense, the garbage heap can and should be regarded as a kind of "gold mine", because waste is a unique resource in its multicomponent composition, in terms of continuity and stability of reproduction ... The owners of this resource (megalopolises, cities with a small population, urban-type settlements, etc.) have the right to dispose of it at their discretion: either, if possible, make a profit, or incur losses from inept management.

And you can use this resource in different ways. For example, the zealous Japanese not only recycle up to 80% of the generated waste, but the "tailings" remaining after processing (the non-utilized part of the waste) also find useful use. To reclaim areas of land that it needs so much from the ocean, Japan uses compacted debris to build dams. So, Odaiba is actually a "garbage" island. The second (less famous, but no less beautiful) of the "garbage" islands is Tennozu. By the way, if Odaiba is known in Japan as a place of romantic dates, then Tennozu is the residence of the wealthy metropolitan public.

In Russia, against the background of the generally undeveloped systemic waste management, the Moscow waste management system is perhaps one of the best today. It is difficult to name any technology for working with solid waste known in the world that would not be used in one form or another in the capital. But it is especially gratifying that today the city government is confidently heading for systemic industrial processing of municipal waste.

However, there is a tendency for a forced sharp decrease in the resource of landfill waste disposal. In this regard, technologies are of particular relevance, as a result of which it becomes possible to significantly reduce the load on landfills, and moreover, to make them environmentally friendly. Modern technical solutions can also solve this problem.

Technological principles of waste management

All used modern integrated systems for municipal waste management traditionally consist of the following main blocks that carry out the following main functions:

  • waste collection (mainly container sites);
  • transportation of waste to sorting sites (traditional garbage trucks);
  • sorting with the release of useful fractions (secondary material resources) and their subsequent direction for industrial processing;
  • neutralization of useless residues ("tailings") and their burial in landfills or incineration in incineration plants with subsequent burial of slag and ash.

In accordance with the waste management concept, implemented, for example, in Moscow, in principle, only that which cannot (or is currently unprofitable) to be recycled is subject to incineration. Only what cannot be burnt should be buried in landfills.

The proposed integrated municipal waste management system (see MSW No. 9, 10, 2007, No. 1, 2008) involves the use of investment-attractive technological and organizational solutions. At the same time, the use of effective technologies makes it possible to really organize the selective collection of household waste, adapted to Russian conditions. The sampling of secondary resources reaches 50% of the volume of all solid waste generated in the serviced area, the volume of "tailings" taken out for disposal is significantly reduced.

The use of the principle of sorting waste in close proximity to the source of their generation also makes it possible to receive and send, including for incineration, waste with a given morphological composition. This will optimize the operation of incinerators.

An additional effect can be provided by the use of a new technology for processing the remaining "tailings" into environmentally friendly (for example, construction) materials. A similar technology and technical means for its implementation were developed by City Waste Technology (Germany) and are used in the city of Manila (Philippines).

To implement this process in the traditional scheme of a waste sorting plant, instead of the final section of “tailings” compaction, three new blocks should be used for burial at landfills. These blocks provide their mechanical processing (grinding), chemical processing and the production of final products.

In the block of mechanical processing there is a preliminary and secondary crushing of "tails" of solid waste, KGM and construction waste.

Providing such a technological process at a waste sorting plant with a capacity of, for example, 100 tons per day, the preliminary crushing of waste occurs using a low-speed shredder with a rotation speed of 23 rpm with a throughput of about 12.5 t / h. At the exit, materials are obtained with a size of about 250 mm. Subsequent secondary grinding makes it possible to obtain fractions of 15-20 mm in size. For this, a high-speed shredder with a rotation speed of 240 rpm is used. with a throughput of about 6.5 t / h. Shredding of construction waste is carried out by a crusher with a capacity of 100-350 t / h. The fine organic fraction is separated using a drum sieve (throughput approx. 6.5 t / h).

Photo 2. Treatment of shredded waste in the reactor

Chemical processing of the resulting material allows for its neutralization, disinfection (destruction of bacteria, fungi, etc.), neutralization and immobilization of heavy metals. The process itself takes place in a special step-type reactor (capacity - 3000 l / step) using a planetary vortex mixer. In the reactor, the crushed material to be processed is mixed with special chemical ingredients, as a result of which it is chemically treated. The chemical ingredients are supplied to the reactor from a compact unit in which the reagents are mixed, stored and dispensed.

The material completely neutralized in this way, already as a raw material for the production of building materials, enters the production unit, where it is mixed with cement and various inert additives. A loading unit with a bucket lift, radial and planetary mixers can be used as the main units of the block. After molding, building materials are obtained.

Photo 4. The production process of "garbage concrete"

This technology makes it possible to obtain up to 800 tons of building materials from 1,000 tons of waste, the range of which can include up to 200 items (building blocks, panels, paving slabs, bricks, concrete pipes, tiles, etc.).

The type and quality of concrete products depends on:

  • morphological composition of waste (in this case - "tailings");
  • the type and amount of inert additives (sand, gravel, recycled building materials);
  • the type of cement, its quantity and quality;
  • cement additives (plasticizers, accelerators, hardeners);
  • used production technology, machinery and equipment.

Photo 5. Building materials obtained as a result of MSW processing

At present, the first samples of building materials made according to the above technology have been received and tested in Moscow. The technical specifications for solid waste-fillers and specific types of products with their use, as well as technological regulations for the manufacture of building materials and products with the use of solid waste-fillers have been developed and are being developed.

The Federal Service for Supervision of Consumer Rights Protection and Human Welfare issued positive sanitary and epidemiological conclusions (No. 77.01.03.571.P.016782.04.06 dated April 3, 2006 and No. 77.01.03.574.P.016764.04.06 dated April 3, 2006 d) for compliance with state sanitary and epidemiological rules and regulations of the following design documentation and products:

  • TU 5712-072-00369171-06 "Solid waste aggregates for concrete";
  • TU 5742-073-00369171-06 "Concrete based on solid waste aggregates";
  • aggregates from solid household waste for concretes manufactured according to TU 5712-072-00369171-06;
  • concrete based on solid waste aggregate manufactured according to TU 5742-073-00369171-06.

As a result of the implementation of the entire technological complex under consideration, almost 100% processing of the flow of all waste generated in the serviced area is ensured into secondary raw materials and building materials - environmentally friendly liquid goods.

The materials obtained are suitable not only for construction work, but also for the reclamation of old landfills. Reduces the release of leachate entering wastewater, the emission of greenhouse gases. When the resulting concrete blocks are removed (with the maximum use of household waste as fillers) to new landfills, the release of landfill gas is generally reduced to zero. Accordingly, the use of all recycled "tailings" in construction, the area of ​​landfills can generally be reduced to zero, which will lead to a significant improvement in the environmental situation in our country.

The project is characterized by financial efficiency and a relatively low (in comparison with other waste treatment technologies) level of required investments.

In recent years, large industrial enterprises have often been accused of damaging the environment. Apparently, therefore, now more and more business ideas began to appear, in which mass production is combined with benefits for the ecological situation on the planet. One of these business ideas can be called the production of building materials from waste from other industries, or, simply put, from waste.

Let's look at one of the existing types of production of similar building materials - bricks and blocks from recycled materials.

How you can use "trash" to make bricks

I would like to note right away that all examples of the production of bricks and blocks from waste from various industrial industries are at the level of startups. But all these are more than promising projects, each of which can grow into a highly profitable business.

And immediately I want to consider why such a business has great prospects:

  • Cheap raw materials. What will become raw materials for the manufacture of your products is considered by other manufacturers as waste that must be disposed of, spending their own resources. Offer waste disposal services to such businessmen or municipal organizations, and you will provide yourself with cheap raw materials.
  • Opportunity to win tenders. If you have to participate in tenders to start a business, then you will be on your side that with your production you will improve the environmental situation in the region and provide the market with affordable building materials.
  • Wide target audience. The building materials you produce will be interesting for low-rise construction, the creation of sewerage systems, the construction of workshops and production facilities, etc. The demand will be supported by an affordable price, which is 10-15% lower in comparison with traditional building materials.

The prospects are great. Now let's look at how they are already being implemented in practice.

Examples of brick production from recycled waste

Now let's consider several options for using waste for brick production:

Boiler ash bricks

This technology was developed at the University of Massachusetts, proved to be successful, and is now being implemented in construction works in the Indian city of Muzaffarnagar. Ash from the boiler house (70%) is used as raw material, to which clay and lime are added. Before that, boiler ash was simply buried in the ground. And now it is possible to build comfortable housing from it.

Building waste blocks

The next example is about making wall blocks, not bricks. The production was organized in Vladivostok, where a plant was created for the production of building materials from construction and industrial waste. All this waste is fed into a shredder, crushed, converted into a homogeneous mass, after which blocks are formed from them for the construction of buildings.

Paper bricks.

The last example is still under development. From paper waste and clay, a mass is created, from which bricks are formed, then fired in a furnace. The technology was developed at the University of Jaen, and according to the reports of their researchers, this material can be used to create reliable low-rise energy-efficient houses. True, such bricks have a lower strength than traditional ones, which requires additional solutions in reinforcing the walls of the future building.

The business idea of ​​making bricks from rubbish is an industry that requires exploratory courage, technical savvy and entrepreneurial genius. But if you manage to implement such a project, then you can take a dominant position in an emerging market. And if you prefer a fully developed production of building materials, then it makes sense to do

production of foam concrete blocks and other traditional wall materials. If you liked this material, then share it with your friends - perhaps it will be useful to them too.

Levi "s jacket from military parachute

Levi's Parachute Windbreaker is the classic Tucker inspired by a truck driver's jacket, but made from retired military parachutes that have been cut and sewn into a khaki windbreaker.

The Levi "s brand has already created, using more than 10,000,000 PET bottles in the production of its clothes. In 2012, the company launched the Levi" s Wasteless line, each item of which contained at least 20% recycled material, which corresponds to about eight plastic bottles.

Fuel from plastic bags

Scientists at the Illinois Center for Sustainable Technologies have developed a method by which plastic bags can be processed into high-quality fuel, gas and other useful hydrocarbon products. At the same time, much less energy is spent on transforming plastic than it is produced from.

The resulting gasoline can be blended with biofuel, which will significantly improve its environmental performance. Bags can also be used as raw materials for making solvents, waxes, and lubricating oils. The technology for making fuel, invented by American scientists, involves heating bags in an oxygen-free chamber.

Elephant dung stationery

Bali's Taman Park and Indonesian Safari Park produce paper from elephant dung. The resulting products are environmentally friendly and have all the necessary quality certificates.

Every day, both parks accumulate up to 2.5 tons of elephant dung, part of which is used for fertilization, and the rest for paper production. Elephants can only partially digest grass, and therefore their fibrous manure is suitable for processing. Each individual eats about 180 kg of greens per day, and gives out about 110 kg of potential material.

Cathode ray tube decorative tiles

With the development of high technology, the screens of computers and televisions with cathode ray tubes have been replaced by flat-panel LCD monitors. Moreover, it is the cathode ray tubes that are one of the most dangerous and difficult to recycle waste in the world. In the United States of America alone, about 390 million kilograms of CRTs have accumulated.

The American company Fireclay Tile, which manufactures decorative tiles from recycled materials, came up with the idea of ​​using cathode ray tubes in the manufacture of its products. The tiles are incredibly strong, durable and environmentally friendly.

Fishing net skateboard

American skateboard company Bureo will release the world's first skateboard made from recycled fishing nets. The production of one skateboard will take about 30 square meters of old nets assembled on the Chilean coast.

It looks like a fish in design with a "tail" and a scaly pattern. The wheels of the board will be made of 100% recyclable material. It consists of 30% vegetable oil.

Jellyfish towels and diapers

The Israeli company Cine'al has created a natural material called hydromash from jellyfish, which can be used in the production of baby diapers, towels and nappies. Jellyfish contain up to 90% moisture in their body, making them the most watery creatures in the world. Their body stores fluid in tissues, absorbing water like a sponge.

The creators of the project have calculated that about 70 kilograms of diaper waste is consumed per child per year. Unlike the synthetic materials from which they are made, the hydromash is completely environmentally friendly. It decomposes naturally within 30 days. Cine'al promises that their invention will be inexpensive.

Smog ring

Dutch designer Daan Roosegaarde created costume jewelry out of smog. To do this, he developed a special vacuum system that sucks the city soot directly from the air, and placed the collected particles in artificial crystals for rings.

The jewelry created is designed to remind people of environmental pollution. They clearly show the composition of the air we breathe. All the smog for the rings was collected in Beijing, where the problem reached a critical level.

Eco-friendly cement from toilet bowls

From Brazil, Spain and England, she learned how to make sustainable cement from old toilet bowls and other ceramic waste. The resulting solution is stronger and more durable than the cement that is used in construction today.

It is made by grinding ceramic waste, which turns into dust and mixes with water. Then an activator is added - a mixture of sodium hydroxide and sodium silicate. The resulting mass is poured into a mold and subjected to intense heating.

Bamboo toilet paper

The American company Nimbus Eco has developed an environmentally friendly paper made from bamboo and sugarcane. It is suitable for the production of toilet paper, napkins and disposable towels. Bamboo makes products durable, while sugarcane fibers give the paper the softness it needs for leather.

According to research, the average American uses over 23 rolls of toilet paper every year. If every resident of the United States replaces at least one roll of ordinary toilet paper with bamboo paper, it will help save about 470,000 trees a year.

Brick has always been and is, perhaps, one of the most demanded building materials, from 3-2 millennia BC to the present day. And this is not surprising if you take into account its combination of qualities - versatility, reliability, excellent performance, a pleasant price.

There is a stable demand for this material at any time of the year, so a brick production line is quite a profitable business. In addition, despite decent competition, the current growth in construction enables entrepreneurs to successfully create and develop their businesses. Why not take a chance then and give it a try? Especially for those who have decided, within the framework of our article we will discuss the main points that you need to know before starting to deal with organizational issues.

Brick making methods or future range of your production

By definition, a brick is a stone of artificial origin, made from mineral components and having a rectangular shape. However, external indicators, performance properties and the method of manufacturing products may vary.

Execution method:

  • Silicate brick. The main components are water, quartz sand and air lime.
  • Ceramic brick. Made from clay.
  • ... Waste from the asbestos, metallurgical, cement and mining industries are used as raw materials.

Scope of application:

  • Building bricks (solid and hollow) are indispensable for laying wall structures, stoves and other structures.
  • It is a smooth block with many voids in the "body", which makes it very lightweight and is successfully used for finishing and decorating buildings.
  • Clinker - used for covering roads and decorating the exterior of buildings.

Main characteristics:

  • By the appearance of the surface, the brick can be - smooth, embossed, with a chipped texture.
  • In color - white (silicate), red (clay) and yellow.
  • By size - single, one and a half, double (for example, double sand-lime brick M 150), non-standard.
  • Based on, there are the following brands of bricks - F15, F20, F30, F50, F100.
  • Based on water absorption - the range of this indicator can be in the range from 6 to 16%.

Ceramic bricks - a traditional way of making

The clay brick making business is perhaps the most expensive in all plans (free space, equipment, fuel, electricity, raw materials, number of employees, etc.). However, it is also the most profitable - the high production capacity makes it possible to quickly recoup all the funds spent.

The main component for ceramic bricks is clay, which, depending on the deposit, can be of different quality. It is the proportion of clay in the composition of the brick that determines the quality of the products themselves.

For example, air-dried adobe brick usually consists of clay and straw and therefore has a low content (less than 30%) of the main component. Understandably, the properties and durability of such a brick will be much less than that of terracotta products, 75% clay.

Ceramic bricks are made by plastic forming. For a better understanding, we will consider this technology in stages:

  • First of all, raw materials are prepared- the clay is moistened with steam and carefully processed until a plastic mass is obtained, without large stony particles (this procedure replaces the traditional aging process).
  • Then the formation of the raw brick is carried out. The prepared clay strip is cut by an automatic extruder. At this stage, the size of the bricks is slightly larger than the standard size, as subsequent processing (drying and firing) will shrink them.

  • Drying is perhaps the most difficult and important manufacturing stage. After all, you need to dry slowly, make sure that the evaporation rate does not exceed the rate of its migration from the inner layers. And if this instruction is not followed, the brick will simply spread. As soon as the moisture content of the product is 6-8%, it can be sent for firing.
  • The final stage is firing. For this purpose, ovens of various designs are used: these are old ring ovens, in which bricks are stacked and removed with our own hands, and modern tunnel units, where products are fired as they move through the oven. The firing temperature depends entirely on the composition of the raw material (usually it varies in the range from 950 to 1000ºC).

After firing, the structure of the brick completely changes: now it is a stone-like artificial building material, durable, resistant to temperature extremes, moisture and has other irreplaceable properties.

It should be noted that ceramic bricks can be solid and hollow. What is the difference? The presence of voids not only improves the quality of the product (in particular, the reduction in mass and the coefficient of thermal conductivity), but also facilitates the production process. The bricks go through the drying process much faster, since the voids make it possible to increase the uniformity of the heating of the product. As a result - lower fuel consumption, not at the expense of, but even for the sake of quality.

Silicate brick - technological nuances

As mentioned above, silicate products consist of air lime and quartz sand. In this case, the production of bricks is carried out using the autoclave synthesis method:

Components are taken in the following proportions: 9 parts of quartz sand, 1 part of air lime and various additives. Then all this is mixed and subjected to dry pressing, as a result of which the future brick is given a standard rectangular shape. Further, the workpiece undergoes autoclaving under the influence of water vapor at a temperature of 170-200ºC and at a pressure of 8-12 atmospheres.

What is an autoclave? This is a steel unit with a horizontally cylindrical shape. In diameter, it reaches more than two meters, and in length - from twenty to thirty meters. The autoclave is closed from the ends with lids, in its lower part there are rails along which loaded trolleys with finished products move.

For information! Bricks made exclusively from basic components (lime and sand) are white in color. To achieve other color solutions, all kinds of alkali resistant pigments are added to the two components.

The uniqueness of the autoclave method of brick production is that it is possible to obtain products of various densities and strengths, using the same components and their processing processes. It all depends on temperature and pressure.

The quality of the finished product is assessed by its technical characteristics:

  • The ultimate strength of the product in compression should not be less than 15-20 MPa.
  • Average density - not less than 1300 kg / m³.
  • Frost resistance (i.e. the number of freeze-thaw cycles that a brick can withstand).
  • Allowable application temperature - no more than 550ºC.

For the manufacture of sand-lime bricks, the following equipment is required:

  • dispenser and sand bin;
  • batcher and bin for binders;
  • twin-shaft mixer;
  • rod mixer;
  • silo reactor;
  • Press;
  • autoclave;
  • automatic stacker;
  • transfer cart for loading trolleys;
  • transporters.

The production capacity of such a line is 20 million tons of products per year. However, for its normal operation, more than twenty employees must be hired (at the rate of 10 people per shift).

Attention! In addition to working hands, you cannot do without a driver, sales manager, accountant, storekeeper and cleaner. Obviously, one person will not be able to follow all the processes related to production.

In addition, it is necessary to take care of the supply of fuel (more than 700 tons per year), a separate building for a brick factory and a truck with a crane for loading, transporting and unloading construction material.

In general, in order to organize silicate brick production in Russia, less area is required than, for example, for the construction of a ceramic factory. In addition, it consumes 2 times less fuel and 3 times less electricity, and the manufacturing process itself is 2.5 times less laborious and time-consuming. Thus, in comparison with ceramic bricks, the cost of silicate products is reduced by about 25-30%.

Hyper-pressed brick as an alternative

If at the moment you do not have sufficient capital to build a ceramic or silicate brick factory, then there is the most budgetary option for organizing a business - the production of hyper-pressed bricks.

In this case, you will need the following equipment:

  • concrete mixer;
  • cement batcher;
  • installation for forming;
  • stove with two sleeves;
  • feeder dispenser;
  • compression installation;
  • receiving and supply bunkers;
  • conveyors;
  • crusher;
  • lifts.

The minimum cost of the above equipment is approximately 10 million rubles. The production capacity of the line is about 4 million items per year.

Important! Better not to skimp on technology. Supported equipment is much cheaper, but regular repairs and, as a result, downtime will make production unprofitable.

For placement of all equipment, as well as for storing finished brick products, at least 400 m2 of free space is required, where the ceiling height will be 5-6 meters or more.

At such a mini-plant, raw materials, as a rule, are taken from the asbestos, metallurgical, cement and mining industries. All costs are recouped in about two years, and the benefit of producing bricks using the hyper-pressed method is about 20%. Nevertheless, the profit from such an enterprise will, of course, be less than from a large ceramic or silicate plant.

So, regardless of which manufacturing method you choose, and what products you will create (for example, the production of facing bricks) - in any case, you will need to consider the following points:

  • The organization of any business begins with the preparation of project documentation. This also includes a business plan for production, during the preparation of which the prospects for the future enterprise, potential profits, and possible pitfalls will be determined. Also, it should clearly describe the production process and technical and economic calculations.
  • Finding a suitable room with an area of ​​at least 500m² and a ceiling of at least 5 meters for a comfortable location of the production line. The most rational solution for the first time is to rent an abandoned workshop, plant, factory, suburban warehouse, and so on.

Note! A room for brick production should ideally be divided into three zones: a warehouse for raw materials, a workshop for production, a warehouse for finished products.

  • Search for a supplier of the necessary equipment, depending on which production method is chosen. Today, there are no difficulties in this, since such equipment is sold in almost every region of the country. However, remember that it is better to purchase it from trusted suppliers located near you. Thus, you simplify the delivery and further maintenance of the units.

  • Hiring workers, even though brick production is semi-automated. We have already mentioned the number of workers and managers.
  • Immediately before the start of production, it will be necessary to conduct laboratory research and testing of raw materials, and then, on their basis, develop the appropriate regulations.
  • Another important question - what to do with the waste of brick production? Perhaps the most rational solution is to take them out to secondary PET. For example, broken bricks make excellent roof tiles. Regular small profits in the "piggy bank" of your budget.

Output

Brick production is a great idea for starting your own business in the construction industry. The main thing is to analyze, plan and organize everything well. Then the demand for products will quickly increase, and the investment will pay off in a matter of time, and the regular profit will grow.

We wish you success in your promising endeavors! And in the video presented in this article, you will find additional information on this topic.
