Biogas is considered a renewable energy source, as it is generated by the composting and decaying of organic matter. It can also be a potent greenhouse gas if it is allowed to escape into the atmosphere. The number of commercial projects utilizing biogas to generate power is growing. Hydrogen sulphide (H2S) exists in biogas at concentrations of up to 0.5%. Even at low concentrations, it is toxic and corrosive. CHAR Technologies has a patented process, which produces biochar that removes H2S from biogas through adsorption filtration.

沼气被认为是一种可再生能源，因为它是由有机物质的堆肥和腐烂产生的。如果允许它逃逸到大气中，它也可能是一种强大的温室气体。利用沼气发电的商业项目越来越多。硫化氢（H2S）在沼气中的浓度高达0.5%。即使在低浓度下，它也是有毒和腐蚀性的。CHAR技术公司拥有一项专利工艺，该工艺生产的生物炭通过吸附过滤从沼气中去除H2S。
