This study aimed to 1) examine the level of acceptance of the innovative briquette system for producing high-efficiency solid fuels from municipal solid waste at Tha Wung Subdistrict Administrative Organization, Tha Wung District, Lopburi Province, and 2) identify factors affecting the acceptance of this innovative system. The research sample consisted of 400 people aged 18 or older living in Tha Wung Subdistrict Administrative Organization, Tha Wung District, Lopburi Province, selected using multi-stage random sampling. Data analysis used percentages, means, and standard deviations, with hypotheses tested using Pearson's correlation and regression coefficients. Results showed that the acceptance level of the innovative briquette system was high, with high levels in all aspects: attitude towards use, perceived ease of use, perceived usefulness, and intention to use. Hypothesis testing revealed that perceived usefulness of the system significantly influenced attitude towards use (β = 0.716) and intention to use (β = 0.343). Intention to use also significantly influenced satisfaction with the briquette system (β = 0.343). Keywords: innovation acceptance, briquette systems for producing high-efficiency solid fuels, municipal waste management. The study aimed to address the growing problem of municipal solid waste and its environmental impact. The innovative briquette system, which uses plastic waste and agricultural by-products, can convert waste into solid fuel, reducing environmental pollution and providing an alternative energy source. The research also aimed to understand community acceptance of this technology, considering factors such as perceived usefulness, ease of use, and intention to use. The findings suggest that the community has a high level of acceptance of the innovative briquette system, which can help reduce waste and improve environmental quality. The study provides insights into the factors influencing community acceptance of the technology, which can guide future implementation and management of waste in the area.This study aimed to 1) examine the level of acceptance of the innovative briquette system for producing high-efficiency solid fuels from municipal solid waste at Tha Wung Subdistrict Administrative Organization, Tha Wung District, Lopburi Province, and 2) identify factors affecting the acceptance of this innovative system.
