Abstract

As the demand of oil palm outputs in the world market and Thailand has increased, it results in the oil palm‘s residues which need to be utilized. The study aimed to investigate the utilization of oil palm’s residues and analyze the greenhouse gas emission from the utilization of oil palm’s residues. The study reviewed related literature to obtain concepts, theories, research works, policies, and measures related to the utilization of oil palm’s residues and interviewed to relevant scholars and agencies. The greenhouse gas emission on the utilization of oil palm’s residues were calculated and then compared.

The study findings revealed the utilization of the residues and the emission of greenhouse gas as follows: cultivation of straw mushroom from empty palm bunch emitted greenhouse gas 323.1264 KgCO₂eq /year; use of oil palm fronds as animal feed emitted greenhouse gas 109.674 KgCO₂eq /year; use of empty palm bunch to cover soil emitted greenhouse gas in total 109.674 KgCO₂eq /year; composting from residues from palm oil extracting plants emitted greenhouse gas 210.346 KgCO₂eq /year, compilation of oil palm fronds in heaps revealed no greenhouse gas emission, and composting from palm bunch emitted greenhouse gas 210.346 KgCO₂eq /year.
