Knowledge Transfer on Value-Added Production from Household Waste to the Grassroots Economy: A Case Study of the Coastal Community in Saensuk Municipality, Mueang District, Chonburi Province

Abstract

This research aimed to study the process of producing value-added products from household waste and the transfer of knowledge regarding the production process using household waste materials. The goal was to develop effective approaches for creating added value and promoting grassroots economic development in Saensuk Municipality, Mueang District, Chonburi Province. The findings revealed that the process of producing products from marine waste materials involved several key steps. The initial step was the separation of household waste, which served as a crucial starting point. Waste intended for transformation into raw materials was sorted. Then, in the transformation process, the sorted waste was crushed using a shredder and mixed with Portland cement at a 1:4 ratio. A removable mold was created using 15-mm thick wood, into which the mixed material was poured while still unset. The mold was left for 40 minutes before being removed, and the resulting product was polished and finished. This process was used in a knowledge transfer activity involving 33 participants. A comparison of scores before and after the knowledge transfer, analyzed using a T-test, showed statistically significant improvements (p-value < 0.05) in participants’ engagement, understanding, and production skills. These results highlight the effectiveness of the training and the relevance of the content, which can be practically applied within the local community context.
