The development of five - level trays type biodryer reactor for processing of organic waste and vinasse mixture into solid recovered fuel

At Malang city, municipal solid waste (MSW) composition is mostly an organic waste that can utilize for Solid Recovered Fuel (SRF). Vinasse is a side product of the bioethanol industry, that mixed with MSW and dried by biodrying technique for solid fuel. The purpose of this research is to evaluate SRF characteristics of organic waste and vinasse mixture generate from biodrying. Research performed by drying the mixture of organic waste and vinasse at (0, 10, 20, 30, 40%) b/b ratio using biodrying reactor with five-level trays. This mixture inserted into the reactor tray, aerated at aeration flow rate 2 L/min from the compressor for nine days. The resulting SRF performed then characterized its moisture content, burning rate, and calorific value. The results showed that the biodryer reactor was successfully made with dimensions of 165 x 50 x 70 cm, consisting of five-level tray with a size of each level tray biodryer of 60 x 45 x 5 cm. The best SFR which has the highest heating value obtained from organic waste with vinasse 10%. It has a moisture content of 11.56%, the burning rate of 0.0135 g/sec, and calorific value of 3912.56 cal/g.
