According to surveys of our clients, urban tree trimmings (branches and trunks removed during the maintenance of green areas) are a valuable and practically free feedstock for biochar production. Many municipal organizations are themselves interested in ensuring that this material is not sent to landfills but instead finds a useful application. As a result, the feedstock is available at zero cost, which makes it particularly attractive for processing.

When tree trimmings are carbonized in SPSC equipment, the resulting biochar has stable physical and chemical properties. This product can be used for soil improvement, long‑term carbon sequestration and as a raw material for sorbents. This approach makes it possible to achieve several goals at once: the recycling of urban biomass, the reduction of landfill volumes, the decrease of CO₂ emissions and the production of a valuable carbon‑rich material.

According to SPSC research, biochar produced from miscanthus stands out for its unique structure. During carbonization of this grass in SPSC equipment, a material with a highly developed internal surface — more than 200 m²/g — is formed. This porosity provides a high sorption capacity. Therefore, miscanthus biochar is often of interest as a product for filtration, soil improvement and carbon sequestration.

Miscanthus feedstock yields stable and uniform biochar with low ash and impurity content. This plant is fast-growing and renewable, which ensures predictable product quality in every processing cycle and makes it suitable for industrial and environmental applications.
