Abstract

Composting is a biochemical process converting organic components into stable compost with release of heat, water, CO₂ and NH₃. The objective of this work was to determine the amount of CO₂ and NH₃ in the exhaust gases during composting of tobacco waste (TW) and mixture of tobacco and grape waste (TGW). The cumulative evolved CO₂ during 21 days of composting of TW and TGW, per mass of volatile matter, was 94.01 g kg–1 and 208.18 g kg–1, respectively, and cumulative evolved NH₃ during composting of TW and TGW, per mass of volatile matter, was 504.81 mg kg–1 and 122.45 mg kg–1, respectively.
