Resources obtained with REVALUO system
Which can be used for transport as a gasoline oxygenator, reducing emissions, for the generation of other types of motor or electrical energy, or the generation of heat.
The water used in the Hydrolysis process is recovered as distilled water. This water can be reused in another subsequent hydrolysis process or, if there is a market for it, bottled and sold at a higher price.
Also called synthetic gas or syntegas, it is a mixture of hydrogen, nitrogen, methane and other gases.
It is a gas that has approximately 55% of the calorific value of natural gas. It is only obtained when treating organic matter, MSW, biomass waste, algae, animal excrement and leachate sludge. It is also obtained from the treatment of industrial waste, oils, ship’s ballast, etc. by means of an alternative process.
It is stored in special tanks with aerators that homogenize all the gases produced during the Thermolysis process.
Charcoal and Biochar
Each ton of waste treated in the Thermolysis plant generates a surplus of decomposed material, free of gases and harmless. The amount of this material will depend on factors such as temperature or morphology of the treated product.
In the case of having treated organic material, animal excrements, biomass residues, algae or any non inorganic element, that surplus produced will be Biochar or vegetable coal.
In the case of treatment of MSW, plastics, tyres and other rubbers, leached sludge or any other type of waste containing an inorganic part, the surplus generated will be charcoal.
Both charcoal and biochar are mainly the same product but with different applications.
The Thermolysis plant can be adapted to treat all types of plastics (except PVC and others containing chlorine in their composition) to obtain a synthetic fuel with a low sulphur content (approximately 1%). The amount will depend very much on the density of the plastic treated.
This product is also obtained by treating rubbers in general and those contained in tyres in particular once the metal and fibre they contain have been removed. In the case of car tyres, between 500 and 600kg of bunker can be obtained from each ton of pure rubber.
The plants dedicated to this use are those that generate the greatest profitability.
In the treatment of pellets from MSW, heat is generated within the Thermolysis plant itself, which varies depending on the composition of the waste, but ranges from 0,4 to 0,6MWh. This heat is not uniform during the whole process but it is usable. Moreover, through a cogeneration engine, with the gas produced when treating a ton of pellets, between 1 and 1,2MWh of heat per ton is obtained, which can be used for many purposes.
From treatment of leachate sludge of class A, B and C depending on the permits and licences held. Due to the high temperature that can be reached in the process, pathogens and toxins are destroyed, and gases are obtained from their decomposition that will be treated by the plant’s gasifier to be able to produce energy through a cogeneration engine. The final waste is presented as a coal smoke, free of harmful gases that can be used as fertilizer in the field, providing nutrients and natural minerals.
Thanks to the important process of separation and classification necessary in the waste treatment plant by the Thermolysis process, a whole series of materials are recovered that can be used for subsequent recycling or transformation contributing to a circular economy; products that would otherwise be buried and forgotten.
Just to mention a few: Paper, cardboard and glass for later recycling. Ferrous metals for smelting or non-ferrous but with a high value on the market, as is the case of aluminium or copper.
Green hydrogen is expected to dominate traditional energy resources in the very near future. The issue of storage of renewable energy cannot be ignored for much longer. Another reason to convert MSW into hydrogen is that landfill waste is a major source of methane — a greenhouse gas that is 84 times more harmful to the climate than CO2 over a 20-year period. Also, it is much cheaper to produce green hydrogen from waste using Thermolysis than by using Electrolysis.
REVALUO system does not need huge amounts of water nor consumption of electricity to generate the H2.
