The waste is an ecological and economic resource

 

Invest in the future with us!

We have created the entire vertical of waste processing.

 

Recycling waste is a safe business venture, there is more and more waste, more and more people live on our planet, and we produce more and more waste. Energy from waste is a growing business, the money is in the streets, you just have to bend for it. Your business can get bigger and bigger with a small investmen. We goal is the local utilization of the waste generated in the community, with local labor, local job creation, to supply local people,  because well as those in the Latin and Tribal regions of the Western Hemisphere, are not adequately served in terms of efficiently utilizing community and agricultural waste or in accessing reliable power sources.

 

  

 

Renewable energy production is a very good business opportunity for businesses,

Extra profit, because we don't have to pay for the waste and we also get money for its collection

 

What can we do to utilize the increasing amount of waste in its material?

 

The conversion of plastic and tire waste into an energy carrier has become relevant, because the production of electricity from waste is slowly being replaced by solar and wind energy, because their operating costs are almost zero.

Electric energy from organic waste

 

Our syngas generator® that produces fuel for the gas engine power generator. A very important aspect at gasification, only pyrolyzed carbon (from RDF / plastic / tire / etc.) can be gasified to a quality suitable for a gas engine. Filter out the tar from the synthesis gas with the resulting pyrolytic carbon, then gasify the tarry pyrolytic coal. The tar produced during the refining of pyrolytic oil can be gasified to produce electricit, very importante because it is very important to know that the tar left over from the refining is 60% of the pyrolytic oil, this is a big loss of energy, so this must also be used for electricity!

 

Syngas calorific value option selection

 

  • From air oxygen, when the calorific value of the produced syngas is 5-6 MJ/Nm3 (since the nitrogen content of the air is 78%, which reduces the calorific value of syngas)
  • With a water vapor plasma torch, when the heating value of the produced syngas is 25-30 MJ/Nm3 (water vapor plasma consists exclusively of hydrogen and oxygen; both components are active reagents that participate in oxidation-reduction reactions. There is no ballast, such as air plasma nitrogen, where its percentage is 78%)

 

New design / built gas generator that produces synthesis gas,

 

from RDF (Refuse Derived Fuel ) and waste tire, waste plastic, etc. pyrolytic coke with oxygen and hydrogen from water vapor plasma for GENSET There is no need for a gas tank in the system, the gas quantity is regulated by the gas quantity demand of the gas engine (engine suction). Gas production stops when the gas engine stops. Syngas production starts when the gas engine is started, continuous electricity production takes place after 15 minutes

 

 

  

 

 

Our carbonization and distillation technology…

 

The breakdown of the heat in the material (components) of our organic waste takes place in an oxygen-free atmosphere, which is environmentally friendly technology, because it is not incineration, but dry distillation in an oxygen-free vacuum space at temperature. 200℃ to 700℃. With our process, the status of waste ceases, and the material of is transformed into many products, such as e.g. diesel, gasoline, heating oil, clean coal, etc.

 

The resulting product gas and the diesel separated in the fractionated condensate can be used directly as fuel in electricity production. The vapors are also condensed into diesel oil suitable for diesel engine fuel, while the resulting gases are used as gas engine fuel and electricity is generated by the electric generators they drive.

 

It can be produced from waste by pyrolysis in an oxygen-free space

 

a)      pure coal (grill coke) for baking and cooking,

b)     oil for the heating and diesel for the car engine

c)      diesel or syngas fuel for electricity generation

 

 

MSW, RDF, plastic, tire, etc. distillation and gasification in water vapor microwave plasma

 

Water vapor plasma consists exclusively of hydrogen and oxygen; both components are active reagents that participate in oxidation-reduction reactions. There is no ballast, such as air plasma nitrogen, where its percentage is 78%. When reacting with chlorine-containing substances, water vapor plasma does not produce dioxin, which is one of the most toxic substances. The flue gases produced during the gasification of the steam plasma do not contain nitrogen oxides.

 

The main advantage of steam plasma reactors is that there is no nitrogen in the steam plasma, the plasma reactor, the gasifier and the plasma afterburner chamber, so there is no nitrogen dioxide (NO2) and nitrogen oxides (NOx). The hydrogen introduced into the reaction space with the steam plasma slows down the reactions of gaseous sulphur, phosphorus and free chlorine formation, i.e. gases that are difficult to remove in the gas purification unit.

Microwave plasma for ionization and thermal decomposition of product gases and flue gases

 

A "plasma filter" is a special reactor in which the plasma-forming gas is actually synthesis gas, which, when ionized, forms a high-temperature field (1500-4000 °C) that effectively breaks down all complex compounds (resins, aromatic molecules, tars, etc.). Our technology is based on the basic properties of microwave plasma, which enable the very effective effect of breaking down their gaseous components. The use of microwave plasma makes it possible to reach an average operating temperature of around 2500 0C. In this case, the heating rate of the various materials in the reactor is 100-1000 °C/s. Parallel to the effect of high temperature, the powerful ionizing effect of the microwave plasma in the reactor volume leads to the complete decomposition of the complex molecules of carbon-containing substances into the simplest molecules and ions.

 

Plasma chemistry

 

When an electromagnetic wave propagates in the plasma, certain reactions occur between the particles.

 

The main types of reactions are:

 

  1. Elastic collision and inelastic collision: such reactions lead to an exchange of energy between particles; the difference between them is that the elastic collision only leads to the transfer of kinetic energy between the colliding particles, but does not change the internal energy
  2.  Excitation and ionization: such reactions result in an increase in the number of free electrons or a change in the energy level of the atom.
  3. Charge transfer: this type of reaction results in an equivalent charge transfer between the particles. This kind of reaction mainly takes place in the collision process of ions and neutral particles.
  4. Charge recombination: it has two forms - diffusion and recombination. Diffusion is the process by which a charged particle reaches the wall and electrode to disappear. Recombination is a process in which positive ions capture a free electron and combine with electrons or negative ions to form new neutral atoms.

Decomposition of flue gas in the microwave irradiated space

 

 

Microwave water steam plasma torch

 

High-power pure steam torch plasma operated by a 915 MHz microwave and its temperature measurements. Steam from a steam generator enters the discharge tube as a swirl gas at a temperature of ~140 °C. This steam becomes a plasma forming gas and produces a stable steam torch plasma. The torch volume is almost linearly proportional to the microwave power. The temperature of the torch flame was measured with an optical spectroscopy, analyzing the optical emissions of hydroxyl molecules ~309 nm.  The maximum temperature in a microwave-driven region was measured to be ~6720 °K

Microwave in the carbonisation – gasification in the non-thermal plasma

 

  • The non-thermal plasma its fundamental nature is that the temperature of the electrons is much higher than the temperature of the gas, including the vibrational and rotational temperature of the molecules. MW alone can reduce the amount of NOx and SOx in the flue gas by 99% and 85%, respectively. Plasmas contain reactive substances, especially ions, radicals or other oxidizing compounds, which can break down polluting molecules, organic particles or soot.

 

  • The electron consumes energy in ionization, excitation and dissociation of molecules and finally in the formation of active free radicals such as OH, O, N and H. These radicals oxidize SO2 and NO to SO3 and NO2, which then react with the water vapor H2SO4 and HNO3 present in the flue gas, and break the VOC bonds, promoting their formation and conversion to CO and CO2

 

  • The atmospheric plasma source is based on a specially designed microwave cavity. Microwaves at a frequency of 1 GHz - 5 GHz are fed into the plasma source, resulting in a high field concentration in the center of the cavity. It is excellent for the removal of highly polluted air pollutants such as volatile organic compounds (VOCs) and their fluorine-containing derivatives (FOCs), the synthesis of special gases and the production of nanoparticles. Microwave radiation is not generated by electrons, but by magnetrons.

 

  • When this radiation comes in contact with carbonic material it unleashes such large quantity of energy that a plasma field is generated. Due to this reaction, the incoming solid material and saturated steam go through a phase transformation that forces the carbon, oxygen and hydrogen molecules to break loose. Once these molecules leave the plasma field they attach to each other forming a new molecular structure, called syngas. 

 

 

Environmental protection in flue gas treatment

 

Our method of filtering flue gas for quality according to EU 2000/76 / EC directives

 

By means of flue gas filtering, the small power plant is inexhaustible for the renewable - with more and more raw materials annually. For the production of electrical and thermal energy from wastes, it is necessary to filter the flue gas produced during the combustion process from the combustion, which is ensured by the ceramic filters and by injecting the adsorbents in front of the filters to the pollutant content according to the EU 2000/76 / EC directives, to the air quality. Emissions from flue gas are below the permissible air emission limits provided by the ceramic filter. The flue gas is filtered with ceramic filters by adding adsorbents. The emitted flue gas component is continuously monitored by the analyzer, the measurement results are documented by continuous data recording.

 

 

 

 

Description of the catalytic conversion of foam ceramic filter elements by calcination

 

Raschig foam ceramic, which Ni, Cu, Mn, Pt, etc. can be made catalytic with metals, e.g. with the following procedure for Ni

 

We use nickel nitrate hexahydrate (Ni [NO3 ]2, 6H2O), AR - grade and calcium nitrate (Ca [NO3 ]2, 4H2 O), AR - grade. Precursors for the preparation of solutions in three different mass ratios 1: 5, 2: 5 and 4: 5. Then, the large-surface ceramic ring carriers are soaked in precursor solutions in a hot pool at 70 °C, and then the gel solution is dried. The wet impregnated and then dried Raschig ceramics were heated in the oven at 110 °C for 24 hours and then calcined at 950 °C for 6 hours. The calcined Raschig catalyzed finished ceramic is stored at room temperature in a closed container next to silica gel.

 

 

 

We offer technology to waste managers

 

Extraction of non-ferrous metals and precious metals from electronic waste

 

  • Electronic waste, PCB, plastic waste with metal, etc. which it is only possible to safely smelt the non-ferrous metal - precious metal content after carburizing. The resulting non-ferrous metal - precious metal alloy can be decomposed into its highly pure 99.99% alloying metals (gold, palladium, silver, copper, aluminium, tin, lead, etc.) in a self-sustaining way in terms of electricity and heat (gas, coke and the so-called pyrolytic oil obtained from energy carriers) in emissions within the limits of environmental protection.

 

 

  • Carbonization prior to smelting facilitates environmental approval in terms of emission limits, because during carbonization, we filter out the polluting components in the organic and inorganic condensate / condensate that would have gone out the smelter's chimney without carbonization. (filtering with condensate is used as a pre-filter for the flue gas)

 

  

 

 

Climate protection with green coal (biochar)

 

"Biochar" is an excellent substitute for soil strength, it is more than a fertilizer

E.g. the corn stalks grown on 1 ha, when charred and plowed, extract 6 tons of CO2 from our atmosphere

 

Biochar is an excellent substitute for soil strength, more than a fertilizer, it can be used for soil improvement, especially in fields with poor productivity. e.g. just mixing 1kg of biochar on 1m2 of soil can increase the crop yield. Biochar makes the micro-flora of infertile soil fertile, and regulates the water balance and water-holding capacity of agricultural land. It forms a good base for the microorganisms necessary for plant growth. Biochar composition: C 77.58%, Volatile matter 12.92%, SiO2 3.5%, Al2O3 1.9%, CaO 1.9%, K2O 0.1%, Na2O 0.5%, Fe2O3 0.75%, MgO 1.3% , P2O5 0.17%)

 

Biochar is a stable material that can be produced from biomass or organic waste of plant and/or animal origin, and which has many applications in environmentally friendly agriculture. Biochar is used to improve the physical and/or chemical and/or biological properties of the soil, and to strengthen the activity of the soil, it is suitable for restoring the natural balance of the soil, it can make crop cultivation economically profitable by improving the drought tolerance of plants, the soil productivity and crop production characteristics.

 

Biochar produced from animal bone is a high-calcium phosphate and low-carbon apatite mineral product, which is a macroporous and slow-dissolving natural organic P-fertilizer. For the most part, hydroxylapatite with a high phosphorus content consists of an inorganic mineral and a carbon component. It has a low carbon content, but can contain up to 30% P2O5, from which phosphorus can be gradually utilized, it has a macroporous structure, which makes it suitable for increasing microbiological activity in the soil, and it also has good moisture binding and macromolecular organic nutrient retention capacity.

 

Plant-based biochar is a soil improvement product with a high stable carbon content, micro- and mesoporous structure, which has a relatively high moisture and nutrient retention and carbon binding capacity. Plant-based biochar is primarily used for soil improvement, and biochar produced from bone meal is used as an organic phosphorus nutrient and also for soil improvement.

Biochar retorts

 

 

  • This can be a mutually beneficial relationship; Biochar can improve the composting process and improve itself at the same time. Reducing nitrogen loss during composting is a notable benefit when compost is supplemented with biochar. The highly absorbent surface of biochar, on the other hand, is "charged" with humic acids, plant nutrients and living microorganisms.

 

  • Nutrient conservation. Plant nutrients are released into the ground water through leaching and into the air through evaporation. This means a decrease in the economy's efficiency and, beyond the fence, an environmental problem. Nutrient pollution is one of the most widespread, costly and challenging environmental problems caused by excess nitrogen and phosphorus in air and water.

 

  • The efficiency of the fertilizer improved significantly after the application of biochar. This was primarily observed as a reduction in the loss of plant nutrients. Like charcoal used for filtration, biochar (a type of charcoal) can help trap plant nutrients in the soil. However, it is important to note that most of the nutrients stored in the biochar are still available to the plant – it resists loss, yet can be used. Mixing biochar directly into compost for a single co-product application maximizes the nutrient retention benefits of biochar.

 

  • Water retention. Where biochar has been applied, soils show higher water holding capacity, better water retention, increased plant available water, increased plant resilience in drought conditions, and increased productivity per unit of water. The yield benefits of adding biochar to agricultural practices in the case of irrigation, the expected result is a reduction in the amount of water needed

 

How it is made biochar and electricity from sewage sludge?

 

 

Our process is a sewage sludge dehumidifier and gasification device, which allows us to use the phosphorus and potassium-containing phosphorus and potassium to dry the wastewater treatment plant (20% dry matter content) in a continuous operation without using an external energy source. and micro elements (Fe, Mn, Ca, Zn and Cu). During the process, starting the system requires only thermal energy, the heating of the radiators, and then the heating value of the dried sludge produces more heat and electricity than the need for heat and electricity in the drying process. The biochar obtained during gasification can be used as an inorganic fertilizer that can be considered as renewable and can be used at any time of the vegetation, due to the lack of nitrogen content.

Biochar does not contain any biohazard component. Because we use controlled sludge from a given wastewater treatment plant, it can be traced well to contain no toxic inorganic components. Summarizing business profits: An essential element of our system is the direct connection of the wastewater treatment plant with our energy recovery system, which eliminates the energy costs of the sewage sludge transport and the pollution of the environment, and from an environmental point of view it is a fact that the drying of the sludge necessary for the energetic utilization of sewage sludge does not have wastewater discharges, as the 80% sludge is vacuum-dried at 80% water. the resulting distillate after condensation of the water vapor is of drinking water quality.

 

Electricity from waste heat

Our machine resource for electric power generation…

 

  • The centrepiece of a waste heat power plant is the swing piston-driven vapour expansion engine (the swing piston expander), which was developed by ourselves, and is manufactured. The swing piston-driven expansion engines achieve an exceptionally high pressure difference, resulting in a much steeper enthalpy gradient and consequently much more electricity is generated compared to related technologies.

 

  • Another considerable advantage of the swing piston-driven expansion engines lies in its impressive partial load capability. The novelty of our system is the use of a motorized "hot air engine" driving the electric generator as a resource expander. The external combustion heat engine is an external heat engine with reciprocating crankshaft mechanism.

 

  • Operating temperature 100°C –  600°C  on  10 bar – 60bar  amd expansion ratio 1:10 → 1:40
