A new composting technology of waste with high fat content was developed in JSC Biocentras. The composting technology of fat-contaminated waste is based on the use of fat-oxidizing microorganisms. Developed technology is commended for cleaner production/pollution prevention approach as well as meets strict environmental and hygiene requirements. The composting process was investigated for the process optimization by applying the response surface methodology. Values of parameters of composting process were monitored in lab-scale composters. The optimal composition of the composing mixture was determined: the initial fat content - 5%, the concentration of bacterial preparation cells - 10(9) CFU/g, the quantity of structural materials - 9.5%. Fat degradation rate slowed down 3 times if the initial fatty concentration increased from 5% to 20%. Concentrated fatty-waste disposal site prototype was designed. Composting process duration lasted 1 to 1.5 year.
