CIRCULAR ECONOMY SOLUTIONS
For Landfill biogas purification from siloxanes and VOC - Applies on-site regenerable adsorption and catalytic combustion of the regeneration off-gas
Siloxanes are responsible for the major maintenance costs of cogeneration engines, while VOC are an issue for CH4 biogas up-grading. Applying our technology, more than 50% of savings is expected on engine maintenance costs and savings up to 10-15 €/1000 Nmc biogas for up-grading units.
For Fermentation biogas purification - Applies on-site regenerable adsorption and catalytic combustion of the regeneration off-gas
VOC are an issue for CH4 biogas up-grading. Unlike activated carbon, that cannot be regenerated with air, our technology applies special adsorbent materials that can be regenerated in-place with hot air. Up to 100k €/y saving for a 1000 Nmc/h biogas up-grading units.
REcat METHANE SLIP
For biomethane off-gas postcombustion – Applies catalytical thermal oxidation with heat recovery
Post combustion of biomethane off-gas is necessary when methan slip is > 1%. Normally, post-combustion applies to combustion off-gases, while biomethane off-gas is 98% CO2, thus requiring huge air dilution in order to provide sufficient oxygen for the reaction. Thermal post-combustion is therefore extremely energy demanding, while catalytic post-combustors are rapidly poisoned and out of use; our technology makes use of non-poisonable catalysts, thus with long life, high efficiency.
For Odour treatment – Applies on-site regenerable adsorbtion and catalytic combustion of the regeneration off-gas
Odour treatment with biofilters is space demanding and not efficient, depending on atmospheric conditions, VOC concentration and biological activity of the filter; our solution is very compact and efficient, performing like a chemical plant, but at very much lower operating costs and with no use of chemicals.
For Fly Ashes recovery- Applies a patented process for complete recovery of precious metals and rare earth, as well as geopolymers production
Acid and basic leaching is supported by electrolytical and fuel cells for complete recovery of precious metals and rare earth; carbonatation allows to recover high quality geopolymers for use in construction.
For Bottom Ashes recovery- applies accelerated carbonatation process
Bottom Ashes are mostly recovered as raw material for road substrates and cement production after washing the high salt content; our technology allows to recover valuable second raw material, such as Al, Ga, Ge, REE, granites for composites (tiles, bricks, synthetic rocks).
For municipal and industrial sludge, primary and secondary steel slags recovery- applies accelerated carbonatation process
Our special carbonatation process allows to recover alkaline sludge and slags into high quality geopolymers for use in construction. Nowadays, materials recovered with existing technology have a low-value market. Our technology allows to obtain valuable second raw material, avoiding waste disposal, capturing CO2 and purifying air and water from pollutants such as NOx and nitrates, sulfates, phosphates.
For CO2 capture from concentrated streams- applies accelerated carbonatation process
Carbon capture form concentrated streams like furnaces, combustion off-gas, chimneys trough chemical reaction of carbonatation with alkaline sludge/steel slags.
