“…Organic waste is the largest waste component contained in MSW that is landfilled, with a mass fraction of 50.86%. This is followed by plastic waste at 25.79%, consisting of 11.74% recyclable plastic waste, dominated by HDPE plastics waste, 13.72% non-recycled plastic waste dominated by colored plastic packaging (10.09%), and laminated aluminum plastic (1.98%) [9]. As stated before, organic wastes are the largest component of MSW, at about 50.86%.…”

“…Previous research using a laboratory scale reactor with 2.5 liter volume showed that the holding time parameter did not have a significant effect; a holding time of 30 minutes was enough to decompose an organic sample [21]. The feedstock materials studied are the most prevalent organic waste components according to the result of a previous field survey for Indonesian MSW: leaf litter (41.50%), food waste (27.97%), vegetable waste (17.32%) and fruit waste (13.21%) [9]. Mahoney leaves were used as representative of leaf litter.…”

“…The previous researches were done at temporary landfills (TPS), where the condition of organic waste is fresher. Further field survey has showed that Indonesian non-recycled MSW consists of leaf litter (34.67%), food waste (23.33%), vegetable waste (14.33%), fruit waste (11.00%), and non-recycled plastic (16.67%) [9].…”

“…A preliminary study on utilization of Indonesian non-recycled MSW has already been done by investigating proximate and calorific values, providing data on water content, physical properties, and calorific value for each waste component, as shown in Table 2 [9]. In addition, there are also some calculations to predict organic and mixed characteristics of a solid fuel from MSW.…”

Municipal solid waste (MSW) is a complex problem in major cities in Indonesia that has not been resolved. MSW is currently only collected and disposed to final landfill. On the other hand, national energy security is also an issue to be solved. Utilization of MSW, which is dominated by organic waste, as solid fuel can be a solution for both problems. This paper discusses an experimental study on utilization of organic waste as renewable solid fuel using a wet torrefaction process. Four types of samples were chosen to represent the four types of organic waste in MSW with the highest mass fraction found in a field survey: leaf litter, food waste, vegetable waste and fruit waste. Each sample was treated with wet torrefaction under four conditions: 150, 175, 200 and 225 ºC with holding time 30 minutes. The experimental results showed that the optimum wet torrefaction temperature for mixed organic waste is between 200 and 225 °C, which is predicted to produce a solid product with a heating value (db) of 23.22-24.44 MJ/kg, volatile matter content of 61.18-66.00%, fixed carbon content of 26.04-31.35%, ash content of 7.47-7.96%, and energy yield equal to 58%. A higher operating temperature will increase the calorific value, followed by a decrease in mass yield as a consequence of the process severity degree. However, food waste torrefaction showed different characterisics: the increase in calorific value was followed by an increase in mass yield. This is unique and different from the results of wet torrefaction on other organic wastes.

Mobilization and population growth caused waste generation and energy supply increments. It requires more efficient waste management and treatment methods. On the other side, the availability of fossil fuel resources decreased, it urges alternative energy sources to take place. One of the waste-to-energy implementations is using domestic waste into briquettes as refuse-derived fuel (RDF) for gasification fuel as the solutions to overcome this problem. Bali Province is one of the targets of the government’s acceleration program for the construction of waste processing plants into electric energy based on Presidential Regulation 35/2018. Waste- to-energy can be applied as co-firing in power plant. This study aims to determine the potential utilization of refuse-derived-fuel as power plant at Suwung Sarbagita Landfill and Bali Province as study case. Wastes are produced into briquette as refuse-derived-fuel. The proximate test results of briquette characteristics were analyzed in laboratory. Potential utilization calculation using data of waste generation in Bali Province, briquette characteristics especially calorific value, and optimal coal and briquette ratio of co-firing process. From the calculation with assuming using Integrated Gasification Combined Cycle (IGGC) system technology with efficiency of 45%, waste in Suwung Sarbagita Landfill, Bali Province has the potential to generate electricity of 101.6 MW.
