Njirimara chemical nke achara
Dị ka ihe biomass, bamboo nwere ihe atọ bụ isi kemịkalụ: cellulose, hemicellulose, na lignin, na mgbakwunye na obere pectin, starch, polysaccharides, na wax. Site n'ịtụle ihe mejupụtara kemịkalụ na njirimara achara, anyị nwere ike ịghọta uru na ọghọm dị n'achara dị ka pulp na akwụkwọ.
