"We remain open to other technologies, but we prioritize those that have been proven to work well in many countries," he said during a press conference in Jakarta on Tuesday.
Speaking alongside Environment Minister Hanif Faisol Nurofiq, he said the government has identified 20 agglomeration areas across 47 districts and cities as priority investment targets for WtE projects.
President Prabowo Subianto has instructed that cities and agglomeration areas generating more than 1,000 tons of waste per day be prioritized.
The 20 areas have met initial requirements and received official approval from the Environment Ministry.
Cities generating 500–1,000 tons of waste per day do not meet the main criteria under the presidential regulation, which prioritizes areas producing more than 1,000 tons daily.
Based on monitoring and evaluation, seven agglomeration areas across 26 districts and cities fall within this category.
"What matters is that the projects are implemented properly, quickly, and accepted by the public, especially in areas where waste facilities will be developed," Rosan said.
He added that equipment could be sourced from countries such as Japan, South Korea, the Netherlands, and China, while some will be developed domestically.
Beyond waste reduction, the WtE initiative is also aimed at developing sustainable alternative energy sources.
President Prabowo expects WtE technology to help clear accumulated waste and convert it into electricity, delivering both environmental and economic benefits.
