Against the backdrop of Indonesia's escalating municipal solid waste (MSW) challenge, Guoxin Group, a leading Chinese provider of integrated waste treatment solutions, is set to deploy its advanced household waste treatment production line and supporting equipment across the country. This initiative aligns with Indonesia's National Strategy for Waste Management 2025 and the newly enacted Presidential Regulation No. 109/2025, aiming to transform waste disposal from a burden into a valuable resource while mitigating environmental risks.
Indonesia is grappling with a severe waste crisis, with an annual MSW generation of 43 million tons in 2023, a 56% surge since 2019 . Over 40% of this waste remains untreated, ending up in unregulated landfills or open dumps that emit massive amounts of methane—accounting for 26 million metric tons of CO₂ equivalent annually . With landfills projected to reach full capacity by 2028-2030 and plastic waste plaguing its oceans, Indonesia is in urgent need of sustainable, scalable waste management technologies . Guoxin Group's tailor-made solutions are poised to address these challenges head-on, leveraging decades of expertise in waste sorting, recycling, and energy recovery.
At the core of Guoxin's offering is its “household waste treatment production line”, engineered to adhere to the principles of reduction, harmlessness, recycling, and energy recovery. The process begins with a “chain plate feeder”, a corrosion-resistant, frequency-controlled device that ensures a steady, uniform supply of waste to downstream processes. This feeder is critical for optimizing the efficiency of subsequent stages, even in the high-moisture, high-organic-content waste typical of Indonesian cities.
Following feeding, the waste is processed by Guoxin's high-performance “shredder”, equipped with twin rotating shafts and high-strength alloy blades. This robust machine efficiently reduces bulky items such as discarded furniture, plastic containers, and organic waste into uniform particles, enhancing sorting accuracy and downstream processing efficiency. Its intelligent control system features automatic start-stop functionality and overload protection, minimizing maintenance costs and ensuring 24/7 operational.
The shredded waste then enters a multi-stage sorting system, combining mechanical precision with manual refinement. The “shaftless drum screening machine”—constructed from 16M steel plate with thick-walled rolling rings—operates at low noise (≤85dB) to separate inert materials like stones, ceramics, and glass from organic and recyclable fractions. Next, the “integrated air separator” (drum density separator) uses aerodynamic principles to sort light materials (plastic films, paper) from heavier components, achieving high precision with a fully sealed negative-pressure design that eliminates dust leakage—critical for complying with Indonesia's strict environmental standards.
A key highlight of the system is its “magnetic separator”, which extracts ferromagnetic metals (iron wires, cans) for recycling, creating additional revenue streams for local operators. For materials requiring manual sorting—such as large debris or hazardous items—Guoxin's “manual sorting table” provides a ergonomic, efficient workspace, with conveyor belts and collection bins.
The most transformative aspect of Guoxin's solution is its ability to convert combustible waste into “Refuse-Derived Fuel (RDF)” using its specialized “RDF forming machine”. This technology compresses organic waste, plastic, and paper into high-density pellets with a calorific value of up to 3,000 -4000 kcal/kg—ideal for use in waste-to-energy plants, industrial boilers, or cement kilns.
"Indonesia's waste crisis is a pressing challenge, but it also represents a tremendous opportunity to build a circular economy," said a spokesperson for Guoxin Group. "Our technologies have been proven in over 130 countries, and we are proud to partner with Indonesian stakeholders to turn waste into a resource—creating jobs, reducing emissions, and supporting the nation's sustainable development goals."
