Process scheme

esquema-en-05

Our patented sorozno pyrolysis system (SPS) transforms waste into energy and usable products. Pyrolysis is thermo-chemical decomposition of carbon based materials with absence of oxigen. Lack of oxigen during the process guarantees very low emisions, in compliance with the strictest air quality rules.

Waste processing

SPS can process a wide range of materials including:
• Commercial & Industrial Waste
• Municipal Waste (MSW)
• Refuse Derive Fuel (RDF)
• Wood
• Green Waste
• Plastics
• Tyres
• Hazardous Waste
• Sewage Sludge

Ideally the waste should have a moisture content of less than 20% before being fed to the SPS. Wet wastes can be dried using heat from the process.The SPS reduces waste quantities by up to 90% producing large savings in disposal costs to landfill.

Sustainable energy

Depending on the feedstock the SPS module will produce between 1MW and 2MW of electrical energy. Roughly twice as much energy is produced in the form of heat which can be used directly for applications such as drying or heating of buildings or greenhouses.

Carbon by-products

The SPS produces a char material that can be used in a wide range of applications. It can be sold as carbon black or as a fuel for around 55€ per tonne.

Charcoal is an internationally traded commodity currently being sold for around 220€ per tonne.

When produced from clean wood or green waste the product is known as “biochar”. The market for biochar as a soil amendment material is growing rapidly around the world, particularly when it is enhanced by minerals and other fertilisers. Biochar has been shown to reduce water and fertilizer requirements by at least 50%.

Further processing of the char using heat from the SPS converts the material to activated carbon – a valuable filtration material used in water purification and food applications. Activated carbon is internationally traded, currently for around 1100€ per tonne.

Solid waste is initially sorted to remove recyclable materials. The residual waste is shredded before being fed into the SPS through an airlock to ensure an oxygen deficient environment in the retort chamber. The SPS then heats the waste materials to temperatures of up to 1000ºC producing syngas which is then cleaned and fed to a gas engine or turbine generator.
