Determining A Model for Municipal Solid Waste Treatment using Mixture Design

The purpose of the study is to propose an optimum combination of waste management to reduce GHG emissions while ensuring feasible economic benefits through the calculation of BCR value using the MD technique of A Simplex Centroid Design consisting of three possible waste treatments, which are composting, reuse, and recycling. The recovery factor of each waste treatment component was analyzed to calculate the GHG emission. The result showed that the MD approach to formulating the possible mixture components of MSW treatment is feasible. Referring to the objective of each response variable, which is to produce the least GHG emission and achieve the highest BCR value, the best value of each mixture component is 95.36 m3/day for composting, 322.29 m3/day for recycling, and 2.35 m3/day for reuse. Therefore, this proposed combination could produce the most negligible GHG emission by 0.029 Gg CO2eq /day while achieving the feasible BCR value of 1.36.
