Thermochemical conversion processes of biomass and waste
Biogreen® is an innovative, patented by ETIA process for continuous thermochemical conversion of biomass and waste residue that allows torrefaction, pyrolysis and high temperature pyrolysis treatment of various bulk materials.
Technology is based on electrically heated screw conveyor (Spirajoule®) designed for advanced thermal treatment. Processed product temperature is precisely controlled basing on the temperature settings. The dwell time of material inside Biogreen® reactor is regulated by screw rotation speed. Thermal conversion is performed in oxygen-free atmosphere in unique construction of pyrolysis chamber which guarantees constant quality of product obtained from the treatment.
What makes Biogreen® unique ?
- Continuous and fully automatic process
- Reliable system for full control of treatment conditions
- Compact, local scale solution for residue treatment
- Small footprint; « lean & mean » equipment
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 high added value materials and energy.
Biogreen is one of the leading processes in Europe, which demonstrated reliability and performance for over a decade of operation. Its great simplicity guarantees high reliability combined with low maintenance and operating costs.
Efficient and precisely controlled conversion of variety of organic materials makes Biogreen® a perfect solution for turning waste into products.
Since years, system supports the industry in management of bulk products, including:
- biomass solid fuels production (torrefaction process)
- municipal waste, industrial waste (RDF / SRF) conversion into electricity
- biochar (soil nutrients and enhancers) production
- conversion of sludge and industrial sludge into heat and electricity
Biogreen® module is designed to process up to 2,5 m3/h. The mass capacity depends on bulk density of material and residence time applied in the process.
