Bio-drying technology is a solid waste treatment with a decentralized system, in which solid waste will undergo biological-mechanical bioconversion. The heat generated from the aerobic decomposition process of organic compounds combined with excess air serves to drain solid waste. The bio-drying process will emit VOCs and other gases that potentially cause global warmings such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) gases. The research method used variation of airflow from 0, 2, 3, 4, 5, and 6 l/m. N2O gases were analyzed using Chromatography gas. The results showed that the bio-drying process was able to reduce the water content from 69% to 40% by the thirtieth day. N2O concentration difference between control (no aeration) and waste with bio-drying processing is 534.69 ppb and 175.48 ppb respectively at 1st day. N2O concentration are known when the bio drying process uses a 4 l / m discharge.
Key words: bio-drying / N2O / global warming / greenhouse gas / solid waste
