摘要: Abstract Landfilling the organic fraction of municipal solid waste (OFMSW) leads to greenhouse gas emissions and loss valuable resources. Sustainable cost efficient solutions need be developed solve this problem. This study evaluates feasibility using dark fermentation (DF) convert OFMSW volatile fatty acids (VFAs), fertilizer H2. The VFAs in DF effluent can used directly as substrate for subsequent bioprocesses or purified from industrial use. Abu Dhabi will economically sustainable once VFA purification accomplished on large scale less than 15 USD/m3effluent. With a minimum selling price 330 USD/tCOD, provides competitive carbon source sugar. Furthermore, is likely use energy conventional processes that produce VFAs, makes promising treatment technology biorefinery platform.
