Abstract

All Utilization of municipal solid waste into fuel requires a pre-treatment process to decrease the moisture content in the solid waste. Bio-drying is a drying method that utilizes microbiological activity of aerobic bacteria to increase the calorific value by decreasing the moisture content in municipal solid waste. The temperature formed in the bio-drying reactor maintained so that the drying process runs effectively by using good insulation. In this research use of nonwoven geotextile as insulation with 600 gsm based polyethylene terephthalate (PET). PET became from a recyclable plastic bottle waste that has low conductivity properties so it is expected to maintain the temperature conditions inside the bio-drying reactor. The results showed that this insulation can reduce moisture content was 51% to 18% and volatile solid loss 86% to 78% for 25 days drying process. Application of nonwoven geotextile insulation is expected to be a solution in the development of bio-drying so that the utilization of bio-drying as solid waste pre-treatment to refuse derived fuel (RDF) can be developed in Indonesia.
