Environmental Impact of Biochar Systems
Biochar systems play a vital role in managing biomass waste, tars, gases, and other materials to reduce environmental stressors. This includes biomass use, pyrolysis processes, end-of-life scenarios, and product manufacturing. The system involves various activities such as biomass production, supply of materials, waste handling, product use, and industrial consumption. Biochar is utilized in different applications like soil substrate mixing, urban greening, and tree planting. The Stockholm Biochar Project exemplifies the comprehensive approach to using biochar for heat generation, waste treatment, and urban landscaping.
