Waste Management
This old saying rings so true today
- as global leaders and local communities alike increasingly call for a fix for the so-called “throwaway culture.” But beyond individuals and households, waste also represents a broader challenge that affects human health and livelihoods, the environment, and prosperity.
- Poorly managed waste is contaminating the world’s oceans, clogging drains and causing flooding, transmitting diseases, increasing respiratory problems from burning, harming animals that consume waste unknowingly, and affecting economic development, such as through tourism
- Plasma waste treatment has over the past decade become a more prominent technology because of the increasing problems with waste disposal and because of the realization of opportunities to generate valuable co-products. Plasma vitrification of hazardous slags has been a commercial technology for several years, and volume reduction of hazardous wastes using plasma processes is increasingly being used. Plasma gasification of wastes with low negative values has attracted interest as a source of energy and spawned process developments for treatment of even municipal solid wastes. Numerous technologies and approaches exist for plasma treatment of wastes.
What is plasma gasification
- Plasma gasification is a process by which the organic portion of any input material is converted to synthesis gas. The synthesis gas is similar to the gas produced by gasification of coal used before the sale of natural gas. There is no burning in this process and therefore no flue gases that emit emissions and thus lead to air pollution.
- In the gasification process, the carbonaceous compounds or organic portion of any material is converted into gas by the high temperatures, which is further useful as a base material.
- To achieve gasification conditions, we supply the process of gasification with the help of plasmatrons and then by partial oxidation, bringing a small amount of oxygen into the process, which is not enough to burn the input material and to produce enough energy for the gasification process.
- HZS Group & CBRN Protection TCT with its partners perform a complete cycle of design and engineering, develops industrial process designs, manufactures units for plasma gasification of carbon-containing wastes with significantly reduce it volume and hazards, obtaining heat and electrical energy, plasma melting units for various non-organic feedstock, units for disposal of biomedical and hazardous chemical wastes.
Unlimited potential use
Municipal Waste
- We most often use plasma gasification for municipal waste. Large cities as well as small towns produce an enormous amount of waste that is mostly sent to landfills or goes through complicated processing to be used as alternative fuel for conven-
tional incinerators. - However, if municipal waste is properly prepared, it is an energy source comparable to coal and with our plasma gasification technology you can effectively convert it into environmentally-friendly green energy.
- This will not only solve your waste storage problems, but will help your town or city district to become energy self-sufficient.
Industrial Waste
- Companies must pay to dispose of their industrial waste. The more complicated the manufacturing technology, the more expensive waste disposal tends to be.
- But with our plasma gasification technology you will transform waste into an excellent source of fuel or raw material. Right at the plant where the waste is created you can generate clean energy that is sent straight back into production.
- Instead of paying for expensive disposal, your waste can help you fundamentally cut costs.
Hazardous waste and hospital waste
- Hazardous waste and hospital waste are becoming increasingly expensive for waste producers. Environmental regulations are becoming stricter and the processing facilities capable of neutralizing hazardous waste are becoming hopelessly overloaded.
- But for plasma gasification, hazardous waste is basically just like any other waste. At a temperature of 5,000°C it doesn’t matter what you burn.
- So if you produce hazardous waste, plasma gasification will not only safely and ecologically dispose of your waste, it will help you cut costs.
- The only difference compared to standard municipal waste is that you must be more careful when storing the feedstock and more thorough when purifying the synthesis gas.
Sewage Sludge
- Sewage sludge was previously taken out to fields as fertilizer. Today this is being done less frequently and in the future will be banned entirely. That’s because sludge contains hazardous substances such as hormones, antibiotics and heavy metals. And when used as fertilizer these substances pass right into our food.
- Thanks to plasma gasification technology, sludge can easily be used to create synthesis gas, which can then be used as fuel in cogeneration units. Cogeneration units produce more electricity than they use, and they also produce heat that you can use to dry the sludge before it is gasified in the plasma reactor.
- So if you are figuring out what to do with the sludge from your sewage treatment plant, plasma gasification is the perfect solution for you. It’s clean, safe, environmentally sound, and makes sludge an asset, not a problem.
Environmental Remediation
- Since combustion at such high temperatures is perfectly clean, plasma gasification can easily be used for environmental remediation. And you don’t have to build your own reactor to do it. We will supply a mobile gasification unit right on the site where the accident occurred.
- The mobile container unit is ideal for cleaning up sites where pesticides or hazardous substances have seeped into the ground. It can handle all waste that is hazardous or impractical to transport elsewhere.
- The mobile unit is naturally also useful in cases where waste is generated once and is logistically difficult to transport elsewhere. For example, military missions or exercises.
HZS Group
- The Consortium has long been focusing on the use of secondary energy sources and advanced gasification technologies, especially high temperature plasma utilization.
- The Consortium implemented the first installation of energy use of landfill gas. To date, the project uses gas from the landfills, produces electricity in cogeneration units and heats over two thousand flats in the housing estate.
- The Consortium has been dedicated to plasma gasification technology, holds several patents in this area and manufactures its own plasmatrons (plasma generators).
- The Consortium has a team of top experts and managers with expertise in plasma, gasification, cleaning and power generation and experience in managing and implementing complex technology projects.
- The company’s research and development activities take place in its own Science and Technology Park.

Equipment we produce
waste water sludge gasification
- The Consortium offers sludge treatment solutions for sewage plant operators employing technologies of high temperature plasma gasification.
- The plasma gasification process consists of the following steps:
- Pressed or skimmed sludge with a water content between 65% and 75% is dried in the first step with a belt dryer. The result is a dry granulate with a residual water content of about 9.5%.
- The dried sludge is carried to the plasma reactor by a spiral conveyor, where the organic substances are converted to synthesis gas at high temperatures. The inorganic part of the sludge melts and forms a lava which, after cooling in a water bath, no longer constitutes waste and can be certified, for example, as a building material.
- The synthesis gas produced is subsequently cooled and removed from the impurities so that it can be used as fuel in the next step. The purified synthesis gas is used in co-generator units to produce electric and thermal energy.
Distinctive features of the technology
- At a time when the end of landfilling is approaching, it is becoming a matter of current concern to find a technology that would not only be economically efficient but also environmentally friendly to handle this waste.
- The technology is environmentally friendly and there are no secondary waste materials to be disposed of. The only by-product is slag. This material is not leachable and it filters with its crystalline lattice unwanted heavy metals.
- The technology produces more electrical and thermal energy than it consumes, so it is not necessary to buy any other fuel for its operation, and excess energy can be used or sold in other customer operations. Waste plastics or biomass can be mixed into the dried sewage sludge to boost electricity and heat production.
- The technology does not need a chimney and does not produce emissions like combustion technologies. Hence, its implementation is easier in terms of the licensing procedure. Another advantage over combustion is the smaller footprint of the technology.
