The effect of the origin of MSWI bottom ash on the HS elimination from landfill biogas.

Municipal Solid Waste Incineration (MSWI) Bottom Ash (BA) is a potential alternative adsorbent for biogas treatment due to its reactivity with hydrogen sulfide (HS). The quality of BA depends however on the nature of the waste and the process technology of the waste incineration facility. To determine whether the origin of the BA could have an influence on its HS elimination efficiency, comparative experimental tests were conducted in a landfill site with six bottom ashes from different MSW incinerators.
