Jiangsu TENESUN Electrical Appliance Co.,Ltd. announces remarkable results from its overseas project in South Korea. The waste heat closed belt-type sludge drying unit delivered to the Korean purchaser at the end of 2025 has operated smoothly for more than half years. All operation indicators stay within standard ranges, fully verifying the outstanding craftsmanship and cross-border adaptability of Tenesun’s sludge drying equipment. This project marks a landmark success of our energy-saving sludge disposal solutions in South Korea’s environmental protection industry.
The Korean client generates 65 tons of organic activated sludge every single day, with raw wet sludge holding 85% moisture. Traditional sludge disposal brought heavy troubles: high transportation fees, fast landfill space consumption and severe secondary pollution risks. Our technical team customized a closed belt drying system to make full use of the factory’s surplus industrial waste heat. After commissioning, the machine reduces sludge moisture from 85% to around 10%, cutting sludge volume by over 75% and greatly easing downstream transport and disposal burdens.
Adopting closed-loop circulation design, the dryer avoids random exhaust emissions and maximizes waste heat recovery. Compared with electric-only drying machines, it slashes energy consumption costs and perfectly complies with South Korea’s carbon neutrality and waste reduction policies. During 24-hour non-stop automatic operation for more than half years, all sub-systems including temperature control, transmission, sealed deodorization and waste heat recovery work in perfect coordination. The client’s on-site maintenance team highly approves our complete sludge drying solution for its simple operation, low failure rate and consistent drying performance.
This flagship sludge dryer is independently developed based on Tenesun’s proprietary heat pump energy-saving technology, specially designed for factories with available waste heat resources. It serves a wide range of industrial and municipal scenarios: municipal wastewater plants, printing & dyeing mills, paper factories, electroplating, chemical, leather and pharmaceutical workshops, as well as kitchen waste treatment facilities.
Strong waste heat compatibility: It recovers steam, flue gas and hot process water waste heat to lower electricity and gas bills effectively.
Safe fully-closed design: Negative-pressure sealed low-temperature drying prevents dust and odor leakage, eliminating flammability risks and meeting strict global emission regulations.
Broad sludge adaptability: Handles municipal sludge, printing sludge, chemical residues, pharmaceutical waste and kitchen waste digestate stably.
Standardized fast delivery: The minimum order quantity is 1 set. Modular manufacturing shortens lead time to 30-45 days, simplifying sea freight and on-site installation for overseas partners.
This stable-running South Korean benchmark project is a critical milestone for Tenesun to explore the Northeast Asian environmental market. In recent years, all countries worldwide have tightened sludge disposal and carbon emission standards, making waste heat recovery closed sludge dryers an essential industrial demand.
Leveraging self-developed heat pump drying core technology, Tenesun optimizes customized drying packages that adapt to local working conditions and environmental laws across different nations. Our products have been exported to South Korea, Southeast Asia, Europe and other regions. Taking this Korean demonstration project as a foundation, the company will further tap municipal and industrial sludge treatment demands in Northeast Asia, supplying cost-effective, high-efficiency and low-carbon sludge reduction solutions manufactured in China.
In the future, Tenesun will boost R&D investment in energy-saving drying technology and enrich our product portfolio covering waste heat, heat pump and low-temperature closed dryers. We aim to provide one-stop integrated solutions for sludge volume reduction, stabilization and harmless treatment for global manufacturers with waste heat resources, empowering the upgrading of worldwide solid waste recycling industries with reliable Chinese environmental equipment.
Tenesun’s waste heat closed belt sludge dryer exported to South Korea in late 2025 has completed of stable trial run. It processes 65 tons of organic sludge daily and lowers sludge moisture from 85% to 10%. Featuring waste heat recycling and fully closed structure, it fits municipal, printing, chemical and pharmaceutical sectors. MOQ: 1 set, lead time: 30-45 days. This overseas benchmark proves global recognition of our Chinese low-carbon sludge drying equipment.
