(NL9100063-A)      Solid organic waste material is successively treated by biological hydrolysis (2) and an anaerobic fermentation (4) with at least part of the material issuing from the hydrolysis treatment treated (5) with at least a microorganism belonging to the rumen flora of ruminants.    Pref. prior to hydrolysis the waste is mechanically reduced in size, sieved and diluted with liq. derived from the anaerobic fermentation; the solid material from the hydrolysis is treated with the rumen flora microorganisms (5) after dilution with liq. from the anaerobic fermentation.    USE/ADVANTAGE -   In the treatment of fruit, vegetable, garden and catering waste etc. in the prodn. of compost or soil conditioner, or for a redn. in bulk. Process produces a higher yield of biogas, a lower yield of residual solids, and has a higher degree of degradation of the waste in a shorter time than in prior processes    (JP6504202-W)      Solid organic waste material is successively treated by biological hydrolysis (2) and an anaerobic fermentation (4) with at least part of the material issuing from the hydrolysis treatment treated (5) with at least a microorganism belonging to the rumen flora of ruminants.

(US5431819-A)      3-Stage process for the biological treatment of solid organic material comprises successive biological hydrolysis then anaerobic fermentation. Hydrolysis comprises acidifying and hydrolysing using bacteria at pH 4.5-7.5, then anaerobically treating at least part of the solid material obtd. with rumen flora obtd. from ruminants (and other opt. microorganisms). Liq. material obtd. from hydrolysis is anaerobically treated with the liq. material obtd. after the other anaerobic treated, using CH4-forming bacteria.    USE -   Used for the treatment of fruit, vegetable and garden waste, opt. after mechanical pretreatment is a destruction.
