Abstract

Solid waste management on Nusa Penida Island is one of the problems in tourism in Bali Province. To deal with this issue, the government has implemented various policies, where the policy that becomes an essential issue is the processing of energy waste. To support this, it is necessary to study the potential of waste characteristics on the island of Nusa Penida. This study aims to analyse the characteristics of waste on the island of Nusa Penida as an energy source based on the generation and composition of waste. Solid waste generation and composition were measured based on land and marine debris data. The total waste generation on land and marine debris can reach 6364.4 kg/day and 762.8 kg/day, respectively. The waste composition materials consist of masks, plastics, metals, and biodegradable organics with a value of 4.12%, 32.77%, 19.54%, and 43.57%, respectively. Therefore, the potential use of organic biodegradable as solid fuel can reach 51,933.8 MJ/day or 14,426 kWh/day. However, in the thermogravimetric analysis (TGA) test, the residue was 18.6%.

Abstract

This study critically evaluated the potential of Refuse Derived Fuel (RDF) as a sustainable substitute for coal in the cement manufacturing process. Using Emplacement Pluit's waste as a primary source, three distinct RDF variations were analyzed: RDF A (comprised purely of PET Charcoal), RDF B (a 50-50 combination of PET Charcoal and organic waste), and RDF C (solely organic waste). Among the parameters evaluated were moisture content, ash content, and calorific value. The results indicated RDF A's superior quality, with a moisture content of 2.6%, ash content of 0.7%, and a calorific value of 25.1 MJ/kg. In stark contrast, RDF C exhibited a high waste reduction potential at 80.5%, but its calorific value fell short of Korean standards. RDF B, balancing quality and reduction potential, achieved a 98.9% waste reduction and met Korean RDF standards, making it the most viable alternative to coal in cement production. The study underscores the significant potential of integrating RDF in industrial practices, particularly cement kilns. It offers insight into optimizing waste management strategies in line with the 'zero-waste' vision.
