NOVELTY - Degrading food and/or organic waste to compost comprise reducing particle size of the waste, dewatering the reduced waste, introducing the dry or semi-dry pulp to a reactor preloaded with a biomaterial including a solid support inoculated with a pre-selected combination of micro-organisms, and treating the pulp in the presence of the biomaterial to degrade the pulp to compost. The treatment of pulp is conducted at 35-50 degrees C and includes agitation phases during which the pulp is mixed with the biomaterial and non-agitation phases during which the pulp is allowed to stand.    USE - For degrading food and/or organic waste to compost.    ADVANTAGE - The process may decompose food and organic waste in a short time frame and results in minimal increase in solid volume within the reactor. Conducting treatment with agitation phases and non-agitation phases results in homogeneous mixing of the pulp with the biomaterial while facilitating rapid growth of the micro-organisms present. The viability and quantity of the biomaterial may be maintained over an extended period of time compared with prior art methods. The biomaterial may be left in the reactor without having to remove compost produced and without replenishment of the biomaterial for at least six months.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) an in-line waste treatment assembly for degrading food and/or organic waste to compost; and    (2) a process for the preparation of a biomaterial including adding a culture medium (2.5 l/kg) to a solid support in a reactor, adding cultures of a pre-selected combination of micro-organisms to the solid support, and allowing the micro-organisms to grow in the reactor.    The pre-selected combination of micro-organisms includes Brevibacillus brevis, yeast Candida krusei, Brevibacillus laterosporus, Bacillus coagulans, Bacillus pumilis, Bacillus licheniformis, Streptomyces avermitilis, Bacillus mycoides, Bacillus firmus, and/or Pseudomonas alcaligenes.
