Waste Management in Accordance with Environmental Protection

The production of machinery, the conversion of solid waste into secondary raw materials as well as the transformation of organic waste into ecological fertilizers, and production of RDF fuel from waste residues are part of the main tasks Croatian-based company Tehnix performs. In order to obtain an overview of the company’s technology in the service of preserving the environment the president of the company Đuro Horvat answered the following questions from GLOBAL RECYCLING.

Tehnix exists more than 25 years, and the company’s main focus is on the production of environmental protection machinery and equipment. In what way do your machines contribute to the protection of the environment?

The company Tehnix has explored and developed the best technologies that allow complete recycling of pre-sorted and/or mixed municipal waste according to use values. A large theoretical and practical knowledge in the development of new machinery and equipment that create the technological manufacturing unit allows a selection of waste into three utility segments for the reuse in the industry. Using factory recycling, we get eight types of clean raw materials that could be sold and returned to the industry. The raw materials obtained from industrial recycling are clean, fast-operated, baled and cheap. In the company, we have developed new machines and equipment that make the core value of the industrial recycling capability that can be implemented everywhere. By applying new technologies, the world can continue industrial development without a negative impact on the environment.

In which sectors do your machines and equipment enable major benefits in achieving the goals of circular economy?

Our machines enable major benefits in the sector of sustainable municipal waste management. The value of the MBO-Te technology is the permanent sustainable management of mixed municipal waste in standard waste processing plants, creating ecological, economic, energy and social resources. With the MBO-Te technology, we can significantly improve, simplify and reduce waste management, and thus do not pollute space in the city or underground drinking water, reduce harmful emissions, and contribute to stopping climate changes. In conclusion our machines, equipment and technologies significantly contribute to the environmental protection sector, the production of eco compost in bio-agriculture for the production of healthy food, and finally the use of combustible waste residues RDF as a major energy resource in cement production or hot-water heating and in the future of electricity generation.

Tehnix builds “modern standard factories for the treatment of mixed municipal waste”. Do you provide the customers with a complete and fully functional system?

To be exact, we give clients everything they need to build a factory of the highest quality with the highest degree of recycling. Modern standard industrial waste recycling plants provide three segments of mixed municipal waste treatment that recycle waste 100 percent and return it to the industry as quality raw material for the production of new products. A reuse center is placed within the factory.MO = an industrial mechanical treatment in factory plant enables extraction of eight types of raw materials – plastic, cardboard, paper, PET, MET, glass, textile and metal. BO = a biological aerob treatment of organic waste enables the production of eco compost within two months. Biofertilizer contains phosphate which is very important for the production of healthy food. Te = with thermal treatment the combustible waste residues are dried, shredded and baled as RDF fuel ideal for cement production. We manufacture equipment for the usage of RDF fuel in cement plants.

How does the treatment of mixed municipal waste look like in your factories?

This is a technological innovation, a patented technological unit where collected mixed municipal waste is recycled – sorted by use values and returned to the industry as a quality clean raw material: plastic, cardboard, paper, PET, MET, textile, glass and metal from which new products of contemporary design are produced. The high-quality raw materials are baled and packed for sale on the market or in the raw stock. At the beginning of the recycling process, organic waste is discharged from the delivered waste. It is screened, cleaned, dedusted and dried. In this way, recycled waste can be easily sorted by type. To organic waste prepared green waste is added and collected waste wood from the recycling yards and others. We produce eco compost in controlled conditions over a period of two months, enrich it with minerals to obtain a high-quality organic fertilizer with phosphate. All the rest of the various packaging waste and waste, that cannot be recycled and has energy value, is shredded, magnetically purified, baled as RDF fuel and is not disposed at the landfill.

According to Tehnix, the “MBO-Te” is “an innovative technology in waste management”. Which features does the technology offer?

The technology offers simpler disposal in one container, bin or sack, faster and cheaper collection, fewer downtime, higher recyclable rates, and lower dumping rate on landfills. As part of our standard plant, all ecological protection is carried out without a negative impact on environment. The whole plant is prefabricated, mobile and can completely be recycled from ecological site. Our industrial recycling plants are ideal for tourism, cities or states. Furthermore, small space is needed; it is suitable to be built near existing landfills due to their recovery. The longevity of our factories is at least 50 years and the entire investment is payable within five years. It is a technological breakthrough for citizens to pay less, the state is spending less money, there are no missed investments, it is easier to control by state institutions as well as European Union experts. Sustainable development can be achieved faster and cheaper. So far we have built nearly 48 different capacity plants, and received great interest from all over the world. The standard projects are already prepared, and we can give the user a complete offer within the same day. It is extremely important to create a high quality conceptual technological and construction project of permanent functionality. By applying the MO-BO-Te we get more raw materials, more energy, more jobs, satisfied citizens, clean environment and a richer society.

The company’s mission is to help its customers to “achieve better results in Municipal Solid Waste Management”. How does Tehnix pursue this goal?

From day to day we have more and more users of our technology. We have developed standard waste recycling projects, and we produce complete standard equipment of various capacities. Moreover, we help our customers in defining the bidding documentation, detailing the technology and costs. Tenders are being conducted quickly because everything is clearly defined. In this way, we protect the investor and the technology. Until now the money has been invested in buildings and landfills. The entire technological process is technologically connected and it is IT- and business-controlled. We run projects with a “turnkey“ system. We provide a month training to the contractor for achieving the maximum functionality. Moreover, we train the plant operators, maintain the system, provide expert consulting for location and capacity selection.

Our projects are funded by commercial banks, the World Bank and the EU. By applying our technology, waste is becoming an economic resource through which we achieve the goals of the circular economy all over the world. They will produce raw materials and send them to European countries for the manufacturing of new products. New tourism trends and large migration seek new approaches and technologies in collecting and recycling of mixed municipal waste. The Tehnix MBO-Te technology is the technology of the future.This is a global circular economy.

Your company offers facilities for industrial composting for the controlled production of eco compost. How does the daily run look like in those facilities?

We have developed the ideal eco-compost production equipment. Yes, we are designing eco-composting plants of various capacities, mainly near sorting plants or recycling plants for mixed municipal waste, because waste contains organic waste that needs to be separated by a special plant and supplied and formed to windrows for the production of eco-compost. It is very important to mechanically prepare organic and green waste. We have developed the ideal bioreactor composting technology, which means producing high-quality compost within a two-month period. Daily work in these eco composting plants has been technologically defined for all operations, ranging from preparation to the packing of compost for the market. High-quality compost always has a market for healthy food production. Daily work in composting plants is dynamic with good working conditions and without any intense smell. Furthermore, for our invention of bioreactor composting plants, we received a grant of 1.5 million Euros.

Which aspects have to be considered most when building a facility for the controlled production of eco compost?

The size of a composting space and a capacity of the plant are the aspects that have to be considered most. Industrial composting must take place under controlled conditions. This means that the entire technological process of producing eco-compost is supervised. The most important part is to determine the spatial capacity of windrow composting. The dimensions of the covered hall are determined by the number of users and the environment. The composting hall must be provided with water, electricity, compost equipment and a rainwater pool. The height of the hall is aligned with the object of recycling and sorting of municipal waste.

Composting falls into the technological recycling process, which means the separation of organic and biodegradable material which turns into quality fertilizer. It is important to determine the optimum space capacity for bioreactor composting. The roof of a hall can be made of concrete, panels or metal sheets covered with a coat. It is most economical to build a composting hall just next to the sorting plant. The building itself must satisfy the conditions that there is no rain, bora, snow nor leaking of liquids in the space around the composting nor in underground waters. The building itself must be enclosed by a wall of three meters in height to avoid the overcooling by bora and the rinsing of the furrows in rainy conditions. The composting hall substrate should be impermeable reinforced-concrete, the door should enable the material to be fed and transport of compost. The project must meet spatial and ecological conditions. The daily amount of biodegradable waste is approximately 0.2 kg/capita. The amount of green biodegradable waste, leaves, branches, grass, waste wood from recycling yards, old furniture is 0.3 kg/capita.

Apart from providing customers with machinery, equipment and facilities, you offer your own range of utility vehicles called “EKOMUNAL”. What are the main features of your utility vehicles?

We manufacture, service and maintain special utility vehicles EKOMUAL with various capacities of 5, 7.5, 10, 14, 16, 18, 20, 22 m³. Our utility vehicles and upgrades have long-lasting functionality, are cost-effective due to low cost and low fuel consumption, and are ecological because they do not pollute the environment. Upgrade EKOMUNAL is a Croatian product. Today‘s communal companies have to take care of citizens, of smaller environmental protection costs. We use Mercedes chassis on which we install a high-quality upgrade for waste collection. In Tehnix, we want to make a vital contribution to the sustainability of the planet, we want to improve the existing model for separating waste in a home, apartment or factory. It was till now insufficient to use all the economic potentials that municipal waste has. The new MBO-Te technology enables complete industrial recycling of collected mixed municipal waste, achieving the goals of sustainable development and circular economy.
