Abstract

Volatile Solid (VS) parameters are used to study kinetic changes in compost materials. The Michaelis-Menten model is used in determining the volatile kinetics of the process. The composting materials used only are shredded empty fruit bunches (EFB) and palm oil mill effluent (POME) sludges obtained from the palm oil mill plantation. All the composting processes carried out in this study were performed in the rotary drum reactor. This experiment is conducted with 4 different runs. Run A used 10 kg EFB ratio: 1 kg sludge: 5 kg recycle compost, Run B with 5 kg EFB: 0.5 kg sludge: 2.5 kg recycle compost and Run C at 5 kg ratio EFB: 2.0 kg sludge: 0.5 kg recycle compost. The highest temperature achieved is 55°C (Run A), 43 C (Run B) and 53.3°C (Run C). For the final C/N ratios for Run A, B, C and D are 20.61, 17.54, 13.06 and 14.51 respectively. Based on the results of the four Runs that have been done, it is found that the kinetic change in Run has the best mathematical expression y=103.31-0.015x with R-square value of 0.9097 and derived K1 value of this study is 106.0117 and K2 is 0.012.
