Implementation of a new composting technology, serial self-turning reactor system, for municipal solid waste management in a small community in Thailand

“Serial Self-turning Reactors” (STR) is an innovative technology, which was developed to be an alternative organicwaste treatment for small communities in Thailand. It is a vertical-flow composting system which consists of a set of aerobicreactors sandwiched with a set of self-turning units. Combination of those components results to a high performance compostingwith capacity flexible. The pilot-scaled prototype of the new technology has been tested to ensure its effectiveness.This paper focuses on the implementation of STR technology. The study consisted of four parts: 1) selection of a targetcommunity and investigation of its current MSW practice, 2) preparation of a proposal which STR incorporated would andsubmit to the university’s administration for approval, 3) establishment of a demonstration plant and trial on actual practice,and 4) discussion and evaluation of the new technology in general and economical aspects. Thammasat University Rangsitcampus was selected to be the target community to approach the new technology. An improvement program, namely“Recycling and Composting Pretreatment Program” (RCPP) was proposed and implemented. Trial operation on plant-scaleperformed effectively with low running costs. An economic evaluation of STR was carried out to generalize the system

Material flows analysis of plastic in Thailand

A study of the plastics materials flow analysis in Thailand was aim to show the flow of plastic materials through production, consumption, and waste management based on the year 2013 and projection to the year 2020. This paper finds the plastic waste generation increasing steadily in line with population growth and increasing consumption. In addition, the simulation under waste management three scenarios includes the following: the business as usual, increasing recycled rate set on the National Solid Waste Management Master Plan (2016-2021) and increasing in rate of energy recovery by the Alternative Energy Development Plan 2015-2036. The plastic material flow analysis has shown that the implementation of the National Solid Waste Management Master Plan (2016-2021) or the Alternative Energy Development Plan 2015-2036 can reduce uncollected waste and improper waste disposal. Moreover, there is benefit by adding value from recycled materials and energy recovery
