What makes Biogreen® unique. Overview & keypoints

Thermochemical conversion processes of biomass and waste

Biogreen® is an innovative and patented process for thermochemical conversion of biomass, plastic and waste. It includes an exclusive and patented pyrolysis system that extracts useful substances to be used as a source of energy or a renewable product for green chemical applications.

Wood, straw, cereal waste, plastic waste or tires, sewage sludge or methanation sludge… all can be converted into oil, char or coke and gas.

What makes Biogreen® unique ?

    • Continuous & fully automatic
    • No labour and computerized
    • On your own site
    • Simple: Small footprint; lean & mean
    • Money: Change waste into money; Low risk investment

A real industrial innovation

Protected by international patents, Biogreen® is an extremely versatile system that offers a wide range of possibilities for thermochemical conversion of biomass and waste into materials and energy.

Biogreen is one of the leading processes in Europe, which has demonstrated reliability and performance over 8 years of operation. Its extreme simplicity guarantees high reliability combined with low maintenance costs and operating costs.

Biogreen guarantees energy efficiency ratio up to 91%.

Biogreen is perfectly suited for the following applications

    • Production of solid fuel, heat and electricity from forestry and crop biomass
    • Production of liquid fuels and electricity from plastic waste
    • Production of carbon black and fuel from waste tires
    • Energy optimization and biochar production from sewage and sludge
    • Production of soil enhancers and fertilizers (Biochar) from biomass

Application processes

Biogreen can be used for biomass torrefaction. Torrefaction is one of the possibilities to create denser energy. Treatment is achieved within a few minutes in a temperature range between 200°C to 300°C in an anaerobic environment. Biomass will lose weight (around 30%), and become crumbly. This prepares it to be crushed or gasified. Torrefaction also produces a homogeneous product, which can be easily compacted to produce TOP (torrefied wood pellet).
Pyrolysis operates between 400°C and 900°C. The char can be used as fuel, carbon black, or a soil enhancer . The oil can be used as fuel for renewable chemical industries. It can also be refined. Gas can be used as fuel for burner or gas engines or turbines. High temperature pyrolysis also produces high quantity of high calorific value with CH4 concentration up to 50% depending on feedstock quality.
Biogreen® allows gasification (with small amount of air injection) or high temperature pyrolysis (800°C to 900°C). Calorific value of the gas can be in the range between 10 to 30 MJ/m3. After a gas clean up process, gas can be used as fuel for electricity production or syngas production.


Biogreen® module is designed to process up to 2,5 m3/h
