Abstract
In order to determine optimal conditions for maintaining biomass quality during storage, an analysis was conducted to investigate the changes in biomass characteristics in Bangkok, Thailand. The study focused on three types of biomass: Corncob, woodchip, and bagasse, which are valuable renewable energy resources in the region. Each type of biomass was divided into two separate piles: One covered with a plastic sheet and the other left uncovered. Over a storage period of seven months (February-September), various characteristics of the biomass piles were evaluated, including pile temperature, moisture content, ash content, heating value, and dry matter loss. The findings indicate that the utilization of plastic sheets significantly enhanced the quality of corncob and woodchip biomass. This improvement was attributed to reduced moisture content, leading to higher heating values, lower ash content, and decreased dry matter loss in the covered piles compared to the uncovered ones. However, such improvements were not observed in the case of bagasse, as its quality exhibited fluctuations throughout the study period. ? 2023 The Authors. Published by IASE.
