Waste is an ecological and economic resource!

The sad reality is also in the video below

 

     

 

Our revolutionary gasification process for tires and plastics represents a significant advance in the industry.

The microwave steam plasma process we use does not emit NOx, CO, CO2, SO2 and is odorless.

 

 

The transformation from waste into an energy carrier

 

Waste-to-energy plant a great alternative to reduce the area for waste treatment and disposal, in addition to generating energy for all small cities in the region. Many small cities do not have available land for large landfills. A good alternative is to create an intermunicipal cooperative between small cities to share costs, revenues, energy generated and technological knowledge.

 

The conversion of plastic and tire waste into an energy carrier - heating oil, diesel, grill coke, syngas - 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. It is a social advantage if small villages are supplied with locally produced energy, thus creating local jobs for the local energy-using population from waste collected locally, small equipment for micro power plants can also be manufactured locally

 

 

  

 

Disposal and energetic utilization of hazardous medical waste

 

The primary benefit of microwave vapor plasma reactors lies in the absence of nitrogen from the air in the microwave vapor plasma, resulting in only hydrogen and oxygen production from water vapor. This leads to no nitrogen oxide emissions, minimal carbon dioxide, and no odors. These reactors are adept at processing solid materials, toxic gases, and liquids, significantly reducing the volume of hazardous waste by up to 99%. Additionally, microwave technology is effective for neutralizing and disposing of hospital hazardous waste, contributing to hospitals achieving a "no waste" certification.

 

 

 

Wind turbine blades

 

Wind turbine blades can be repurposed in a non-thermal microwave plasma field, where the electron temperature significantly exceeds the temperature of the generated gas, including the vibrational and rotational temperatures of the molecules. Within this plasma environment, complex compounds like resins, aromatic molecules, and tars are efficiently broken down and detached from the inorganic glass fiber reinforcement.

 

 

 

 

Our waste recovery's environmental protection innovation incorporates microwave technology

 

Microwave reactors are remarkable for their ability to achieve average operating temperatures around 2500 ℃, with material heating rates ranging from 100-1000 °C/s. The high temperatures, coupled with the strong ionizing effect of microwave plasma, result in the complete breakdown of complex carbon-containing molecules into simpler molecules and ions. The microwave in reactor space it creates a high-temperature field (1500-4000 °C) that efficiently disintegrates all complex compounds, such as resins, aromatic molecules, tars, etc. This technology leverages the intrinsic properties of microwave plasma for the effective decomposition of gaseous components. High temperatures in plasma jets can disintegrate organic or biological materials, neutralize potent toxins, and melt or vaporize stubborn inorganic substances, thus reducing waste significantly.

 

 

About the microwave vapor plasma torch

 

  • A plasma torch serves as an autonomous heat source, facilitating controlled gasification even when waste composition varies. Utilizing water vapor as a carrier gas for non-thermal plasma at atmospheric pressure enables the reduction and oxidation of free radicals like H, OH, and O, enhancing the treatment of hydrogen-rich compounds such as methane, natural gas, ethanol, and coal.

 

  • Steam 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) nitrogen oxides (NOx) and minimum carbon dioxid (CO2)  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. In microwave steam plasma torches, synthesis gas serves as the plasma-forming agent. Once ionized, it creates a high-temperature field (1500-4000 °C) that efficiently disintegrates all complex compounds, such as resins, aromatic molecules, tars, etc.

 

1400℃ temperature without fossil fuels

„zero carbon dioxide – zero nitrogen oxide”

 

 

A high-power pure steam torch plasma is operated by a microwave ranging from 915 MHz to 2.45 GHz, along with temperature measurements. Steam from a generator enters the discharge tube as a swirl gas at approximately 140 °C. This steam then becomes a plasma-forming gas, creating a stable steam torch plasma. The volume of the torch is almost linearly proportional to the microwave power. The temperature of the torch flame was measured using optical spectroscopy, which analyzed the optical emissions of hydroxyl molecules at approximately 309 nm. The maximum temperature within the microwave-driven region was recorded to be around 6720 °K.

 

New design / built gas generator that produces almost tar-free (5-10 mg/Nm3) synthesis gas,

 

Our syngas generator® that produces fuel for the gas engine power generator. A very important aspect at gasification, only pyrolyzed coal (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. 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

 

Syngas calorific value option selection: a) 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) b) with a microwave vapor plasma torch, when the heating calorific value of the produced syngas is 20-30 MJ/Nm3 (microwave vapor plasma consists exclusively of hydrogen and oxygen; both components are active reagents that participate in oxidation-reduction reactions

 

 

  

 

 

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)

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.

Heat pipes are superconductors of heat conduction

Their thermal conductivity is 1000 times higher than e.g. for solid copper conductors of the same size.

 

Characteristics of the "superconducting heat exchanger"

 

  • Its operation does not require electricity, so no connection
  • Its unclaimed, heat-transmitting metal surface was kept metal clean by ionic separation
  • Its lifespan is endless, as there are no aging plastic, moving or wearing parts

 

 

 

Vacuum distillation of wastewater at ambient temperature

 

The traditional distillation process consumes a significant amount of energy due to the high latent heat of water (620 kWh/ton). Distillation involves evaporation and condensation within a vacuum. The heat energy necessary for continuous distillation is reclaimed from the outgoing distilled water at the start of the process in a closed system using our highly conductive heat exchanger. Both evaporation and condensation occur in the same vacuum space, necessitating only the compensation for vacuum loss caused by non-condensable gases escaping from the wastewater during evaporation and any leaks in the tank-pipe system. This is achieved by maintaining the vacuum pump at an absolute pressure of 7-25 mbar. The energy needed for water evaporation is sustainably sourced from the wastewater, with the system's sole external energy requirement being the electricity to power the vacuum pump.

 

Key economic and environmental features of thermal vacuum distillation at ambient temperature include:

 

  • A lifespan of 50 years for the equipment, barring the replacement of bearings in vacuum and water pumps
  • Automatic operation of the device, which starts and stops based on temperature
  • Maintenance limited to weekly cleaning of mechanical pre-filters
  • No need for wastewater pre-treatment
  • A chemical-free technology that causes no environmental pollution
  • Disinfection of water using chlorine-free O3 ozone and UV-C light emitters
  • The ability to release distilled water back into natural watercourses

 

Economical and eco-friendly uses of thermal vacuum distillation:

 

  • Dehydrating wastewater and sewage sludge, such as heavy metal galvanic sludges
  • Concentrating grape must, fruit, and vegetable juices while retaining their natural flavors and vitamins
  • Distilling alcohol at room temperature without the need for heating, followed by dehydrating the mash
  • Evaporating leachate from municipal waste landfills

 

 

 

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

It’s like spreading kindness and positivity, which can make a big difference in the world.

 

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.

 

Sample plots for comparative measurement of yield

 

  

 

The recommended amount is 4t/ha on hard soil, 8t/ha on sandy desert areas

 

   

 

Biochar "green coal" is the "result" of soil power in pictures

 

 

 

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.

 

Drinking water is the basis of our biological existence, without water there is no life.

 

·       The extraction of fresh water from air and seawater is a given technology, which can be utilized from our renewable energy source, our solar radiation.Water pumps require solar energy (solar panels) to produce fresh water, and thermal energy (solar collectors) is required for vacuum distillation In addition to electricity from solar panels and thermal energy from solar collectors, desalination also takes place from the difference between the temperature of the seawater.
