A newly designed and built fermentation bed utilized plant wastes to receive and mechanically mix with pig excrement for microbial fermentation to result in an organic fertilizer. The facility consisted of a steel framed structure, a pool and a fermentation tank with accessories such as aerator, sprayer and others. The economical, ecological and social advantages with superior effluent control of the new design over the conventional settings for pig farm operations were illustrated.
