Denera's vision — "Sustainable Waste Management Towards a Clean and Prosperous Indonesia" — is built on four strategic pillars: Waste-to-Energy Development, Waste Management Transformation, Sustainable Waste Infrastructure, and Waste Technology Leadership. Together, these pillars form the foundation for Denera's integrated, scalable approach to Indonesia's waste challenge, extending progressively across the entire value chain.
Pengelolaan Sampah menjadi Energi Listrik or PSEL as Part of the Solution Chain means that Waste-to-Energy is one part of an integrated waste management system—not a replacement for waste reduction, source separation, or recycling. PSEL complements these efforts by processing residual waste that cannot be recovered through other methods. As part of an integrated waste management system — spanning source reduction and sorting, recycling, energy recovery, and PSEL — each Denera facility plays its role in a full-cycle approach to municipal waste.
- Indonesia generates approximately 140,000 tonnes of waste per day nationally
- PSEL targets 20–25% of national waste volume as part of the integrated system
The technology that PSEL uses is Moving Grate Incinerator technology — the global standard used in 75–80% of Waste-to-Energy facilities worldwide. Incoming mixed waste is dried for 5–7 days, then combusted at >850°C. At this temperature, hazardous compounds are fully decomposed, not vaporized. The heat generated produces steam that powers turbines to generate electricity, which is supplied directly to PLN's national grid.
Proven at Global Scale with more than 3,100 facilities operating across over 50 countries and processing approximately 640 million tonnes of waste each year. As adoption continues to grow, the global market is projected to reach USD 68.7 billion by 2034. Countries including Japan, China, Singapore, Sweden, Denmark, and Germany demonstrate how Waste-to-Energy can be successfully integrated into national waste management systems.
