Biomass Ash Value-Added Project

Biomass ash is a byproduct of the energy production process at biomass power plants. It is alkaline and contains essential nutrients that plants need, making it suitable for agricultural use as a soil amendment material.

Biomass ash is a byproduct of the energy production process at biomass power plants. It is alkaline and contains essential nutrients that plants need, making it suitable for agricultural use as a soil amendment material. There is significant interest among farmers in utilizing biomass ash to increase agricultural productivity, particularly among bamboo growers, rice farmers, longan orchard operators, and sugarcane farmers, among others. Additionally, biomass ash is also suitable for use in the production of construction materials, such as lightweight bricks or concrete blocks. Since 2013, the company has been collaborating with local educational institutions to study and continuously develop the use of biomass ash.

Utilization of Biomass Ash

The company has applied the results of research studies to further develop and disseminate knowledge on the utilization of biomass ash to farmers and interested parties. This is done through community-based enterprises, training programs, and study tours in surrounding areas. Examples include the promotion of agricultural materials, soil improvement, and planting materials using biomass ash, the "Public-Private Partnership Project: Teaching Kids to Grow Vegetables," and the "Sustainable Kra Prai Project," among others.
