The application of biodrying method for organic waste treatment in Universitas Trisakti, Jakarta

Abstract

Universitas Trisakti has been attributed with many activities and has not been equipped with a proper solid waste management to recover the waste that may contaminate the environment. Biodrying becomes an approach of drying technique utilizing the heat generated by biological activities to degrade the organic waste and also acknowledged to be the proper technique to provide the raw material for Refuse Derived Fuel (RDF). This study aims to conduct the process of biodrying technique carried out in an acrylic chamber with the capacity of 18000 cm3. The source of municipal solid waste supplied by the transfer waste facility in the area of Universitas Trisakti. Only organic waste was used during the biodrying process. Aeration rate was 3 l/min. The biodrying process was observed for 8 (eight) days which the activities of microorganisms were identified at the third days, shown by the condensation of the evaporated water released on the top and side walls of the biodrying reactor. Due to this condition, the designed reactor needs further innovation to avoid the condensation of evaporated water to raise the reduction rate of moisture content. This pretreatment study showed the absence of leachate which proves that the biodrying method has the potential to reduce the negative impact of unmanaged solid waste generation.
