    Over the past decade, PM 2.5 pollution has become an increasingly serious environmental concern in Thailand, with one of its primary sources being the open burning of agricultural residues, particularly sugarcane residues. To mitigate this issue, it is essential to develop alternative applications for sugarcane leaves that eliminate the need for burning. This study investigates a sustainable approach by incorporating sugarcane leaves into producing noise insulation mortar boards. The research aims to assess these boards' acoustic performance through a combination of laboratory experiments and field testing. Employing the Design of Experiments (DOE) methodology, mortar samples were prepared with sugarcane leaf content at 2%, 4%, 6%, 8%, and 10% by cement weight to identify the optimal mixture. Analysis of variance (ANOVA) indicated that the sugarcane leaf content had a statistically significant effect on sound pressure level reduction at a 95% confidence level. Both laboratory and field results demonstrated that the 4% sugarcane leaf mixture yielded the highest performance, achieving noise reductions of 20.6 dBA and 23 dBA, respectively. These findings confirm that mortar boards reinforced with sugarcane leaves effectively reduce noise and offer a viable solution for repurposing agricultural residues. This approach contributes to noise pollution mitigation and addresses environmental concerns related to the open burning of biomass.

    In Thailand, the use of biomass for electricity generation has been implemented with incineration technology for many years. However, recent reports indicate that electricity demand is still high and biomass power plant is one of the key factors for electricity management. The major purpose of this research paper is to analyze the energy, economic and environmental features of biomass power plant for the national sustainable development strategy. An existing 9.9 MW biomass power plant located in Suphanburi is selected as the case study to assess thermal combustion for electricity generation. The in-house operations of biomass-based power plant and the process flow of energy in terms of electricity generation using agricultural wastes and forestry residues are provided. Different expenses like capital cost, processing cost, and transportation cost and the major revenue from the sale of electricity are taken into consideration. Five environmental factors (air, sound, water, ash, and transportation) of biomass power plant for sustainability are investigated. Findings from this research project indicate that incineration is a suitable technology for biomass-based electricity generation with considerable profit for all stakeholders.
