pyrolysis and gasification process transform wastes into valuable products for soil upgrade, plastic composite, substituting fossil carbon/gas in processes
About
Gasification and pyrolysis processes are thermochemical processes, which are capable of converting different kind of carbonaceous wastes into valuable products. In a regional/decentral context such robust technologies can be applied to convert local available residues and waste streams in local applications: e.g. agriculture, construction, manufacturing, product design (batteries and plastic composites), substitute of fossil based carbon/gas applications. BEST is capable of scanning different feedstocks in order to allow deployment of optimal technology configurations and product qualities for the regional and highly individual application.
Key Benefits
- the upcycling of wastes is integrated and contributes to the cascadic utilisation of residues. By using end-of-pipe residual streams, or wastes from microbiological treatment (e.g. biogas residues, fermenting processes,...) or hard to classify carbonaceous wastes, upcycling of feedstock can be used to bring a certain share back into the cycle. - The products of this upcycling allow the substitution of fossil energy carriers also in energy intense branches like cement or steel production - By deploying robust and highly versatile technologies, in particular the locally and regionally different needs can be addressed.
Applications
- agriculture: utilization of (own) agricultural residues for the production of biochar and renewable energy. Via biochar nutrients can be recycled in line with the principle of the circular economy. Moreover, biochar application can improve the capacity of nutrient storage and water conservation in the soil, creates good growth conditions for a healthy soil microbiome and contributes to the build-up of humus. Self-sufficiency with biochar avoids monetary expenses for purchasing coal and can increase the added value by utilization of residual materials. - construction: biochar and crudes may act as additive in street construction but also in concrete, strongly enhancing the stability. Besides that material benefits, additional carbon sequestration acts as long-lasting sink for carbon. - plastic composites: biochar is adding electrical and mechanical properties to the composites - batteries: uniform and high electric conductivity is necessary for collectors in battery design. - gas for high temperature furnace applications substituting natural gas sources e.g. in aluminum melting, glas melting,...
