Abstract

This paper shows the possibility of moving in a matter of weeks from mesophilic (37°C) to thermophilic (55°C) conditions in the anaerobic digestion of the organic fraction of municipal solid waste (MSW) at high levels of solids (20%). After the temperature increases, a first pseudo steady-state condition can be reached after a month and a final steady-state condition after 2 months. No particular evidence of digester instability was observed using this approach in changing temperature range. The higher yields obtained in the latter condition (110% larger in terms of specific production) are shown. © 1993, Sage Publications. All rights reserved.
