Abstract

The invention relates to a method for treating waste products in particular animal manure slurries to produce methane. In the method of the invention acidification and methanogenesis is carried out in two separate stages and in separate containers. The slurry is first held in a holding tank to allow acidification to occur and a liquid fraction comprising the volatile acids produced is separated from a solids fraction. The liquid fraction is then passed to an anaerobic digester in which the methane bacteria is supported by a holding matrix. The invention also includes apparatus for use in the method comprising a holding tank in which acidification of the slurry occurs, means for separating the liquid and solids fractions of the slurry, means for feeding the liquid fraction to the digester which contains the holding matrix, and means for removing methane and residual effluent from the digester.
