The research aimed to study the acceptance level of an innovative briquette system for producing high-efficiency solid fuels from municipal solid waste and to examine the factors affecting the acceptance of this system at the Tha Wung Subdistrict Administrative Organization in Lopburi Province, Thailand. The study involved 400 community members aged 18 and over, using multi-stage random sampling. Data analysis was conducted using percentages, means, and standard deviations, with hypotheses tested using Pearson's correlation coefficients and regression correlation values. The results indicated that the acceptance of the innovative briquette system was at a high level, with the following aspects being highly rated: attitude towards use, perceived ease of using the system, perceived usefulness of the system, and intention to use the system. The perceived ease of using the system had a significant effect on the attitude towards use (β = 0.176), while the perceived usefulness of the system had a significant effect on both the attitude towards use (β = 0.716) and the intention to use (β = 0.343). The attitude towards use also had a significant effect on the intention to use (β = 0.503), and the intention to use had a significant effect on satisfaction with using the briquette system (β = .343). Keywords: innovation acceptance, briquette systems for producing high-efficiency solid fuels, municipal waste management The study highlights the importance of sustainable energy solutions to address global energy demand and environmental challenges, particularly in the context of Thailand's energy policies and the need to reduce greenhouse gas emissions. The development of an automated briquette production system from municipal waste is seen as a promising approach to manage waste more effectively and promote sustainable development.The research aimed to study the acceptance level of an innovative briquette system for producing high-efficiency solid fuels from municipal solid waste and to examine the factors affecting the acceptance of this system at the Tha Wung Subdistrict Administrative Organization in Lopburi Province, Thailand.
