600 kW pyrolysis gas output. 90 kW usable heat output from exhaust gas heat exchanger. 250 kWth heat output*. 220 kWel power output*. 450 t biochar / year. 1,400 t of permanently removed CO2 per year.

The Autarkize biomass pyrolysis system offers an innovative approach to converting organic residues into energy-rich pyrolysis gas and biochar. Utilizing a pyrolysis process, the system carbonizes and gasifies various carbonaceous materials, such as residual and waste wood, pomace, sewage sludge, green waste, and fermentation residues. The resultant pyrolysis gas is composed of approximately 25% hydrogen, 30% carbon monoxide, 15% methane, and 25% carbon dioxide, with specific ratios dependent on process control and water content. This gas can be used to generate electricity and heat on-site with standard technologies, producing significant revenue and reducing CO2 emissions by up to 6,000 tons annually. The biochar generated serves a multitude of purposes, including soil enhancement and permanent CO2 sequestration, contributing to the global effort to combat climate change. The system is designed for high economic efficiency and flexibility, permitting the use of diverse biomass inputs and ensuring rapid amortization within 2-5 years. Its compact and maintenance-friendly construction further reduces operational costs and downtime. Available in three sizes, the Autarkize system can cater to various needs, offering multiple revenue streams including renewable energy production, biochar trade, CO2 removal certificates, and avoided disposal costs.

The Autarkize biomass conversion system is engineered to maximize efficiency by utilizing a variety of biomasses with a dry mass of approximately 80% and a grain size under 45 mm. It operates in two reactor stages: in the first stage, the biomass is heated and high-quality pyrolysis gas is purified. In the second stage, biomass undergoes carbonization in the absence of air at 400-700°C, yielding high-purity biochar. The energy-rich gas produced is further purified in the first reactor and partly redirected to heat the process, making it highly self-sustaining. These systems provide a thermal output between 200-1200 kW, suitable for generating electricity, steam, and heat. With advanced gas purification technology and energy density comparable to biogas, our solutions are capable of handling both base and peak load requirements. The process is efficient at reducing CO2 emissions, turning organic residues into valuable biochar and heat. Join us in pioneering sustainable energy solutions with the Autarkize system.
