“Supercritical water gasification of palm oil mill effluent”

Palm oil is the foremost industry in Indonesia with severe waste byproducts that are harmful to the environment; however, it has excellent potential as biomass resource. Palm oil mill effluent (POME) is the most problematic waste generated from palm oil production process. It is made up of water, oil, solids, suspended solids, and many valuable nutrients such as phosphorus. Supercritical water gasification (SCWG) is a promising method for thermochemical conversion of biowaste into valuable gas. The recovery of valuable nutrients in parallel with energy production could make this process becomes more economically beneficial. There are no comprehensive studies on gas and phosphorus production from POME by SCWG. Thereby, evaluation of the products, reaction mechanism, and reaction kinetics are essential to optimize the process. Furthermore, study of the effect of heating rate on POME conversion could help to guide the optimization of the POME recycling process. Besides the POME conversi
on, the kinetic study of model compound (glyceraldehyde) will give the key point for the detailed mechanism of lignocellulosic biomass conversion in hydrothermal gasification. This study will also be discussed in this research.

“Diversity in the nature and agriculture”

Life of healthy people relied on two activities: Agriculture and Industry. Sustainable environment always stays as promised background of these two human activities. Now, however, this legend was lost. We must build sustainable environment and reliable nature through Agriculture and Industry for our further survival with quality of life (QOL). In this presentation, I would like to introduce the diversity in the nature and agro-ecosystem, and would like to discuss about the way to handle it.
