In a landmark achievement for Chinese industrial innovation, Sichuan Chuanguo Boiler Co., Ltd. (SCBC), a key subsidiary of Jianlong Group, has received international acclaim from the United Nations Industrial Development Organization (UNIDO) for its cutting-edge “High-Temperature Solid Bulk Material Direct Waste Heat Recovery Technology.” The technology has been officially included in the Global Environment Facility (GEF) “Industrial Heating Systems and High-Energy-Consumption Equipment Energy Efficiency Promotion Project” and awarded the “Energy-Saving Technology Product” Demonstration Certification.
This milestone marks the first time a Chinese-developed industrial waste heat recovery solution has been systemically endorsed by the GEF platform for global deployment—signaling that SCBC's innovation has reached internationally advanced standards, with its core solid-to-solid heat exchange technology recognized as world-leading.
Traditional waste heat recovery methods for high-temperature solid materials—such as blast furnace slag, steel slag, and boiler ash—often rely on intermediate gaseous media or complex multi-stage processes, resulting in low efficiency, high energy consumption, and secondary pollution. SCBC's breakthrough eliminates these limitations through an elegantly engineered, gravity-driven system：
| Direct heat exchange | Unprecedented efficiency |
| Hot solid particles flow slowly by gravity through a moving packed bed, transferring heat directly to boiler water tubes—producing high-quality steam for power generation without any intermediate heat-transfer fluid. | The system achieves over 80% waste heat recovery efficiency, double that of conventional technologies. |
| Ultra-low self-consumption | Integrated cooling & recovery |
| Power usage is reduced to just one-third of traditional systems thanks to passive gravity flow and minimal mechanical intervention. | Combines material cooling and energy capture in a single unit, slashing footprint, maintenance costs, and operational complexity. |
| Zero secondary emissions | Fully automated & intelligent |
| Operates in an oxygen-free environment, preserving material properties while ensuring no air or water pollution. | End-to-end digital control ensures safe, stable, and labor-efficient operation. |
| Driving Decarbonization at Scale
Deployable across heavy industries—including steel, power generation, petrochemicals, and non-ferrous metallurgy—SCBC’s technology offers a mature, scalable pathway to deep decarbonization. When widely implemented, it is projected to |

| Save millions of tons of standard coal annually | Reduce CO₂ emissions by over 10 million tons per year | Deliver significant cost savings through energy recovery and process optimization |
| “This isn't just an engineering upgrade—it's a strategic enabler for global industrial net-zero transitions,” said a senior SCBC R&D executive. “We've turned waste heat from a disposal problem into a clean energy asset.” | ||
Opening Doors to Global Green Markets
The UNIDO/GEF certification serves as a “green passport” for SCBC, facilitating access to international climate finance mechanisms, carbon markets, and sustainability-focused procurement programs. Critically, the technology's quantifiable energy savings can now be monetized through verified carbon credits, enhancing ROI for adopters worldwide.
As part of Jianlong Group's broader commitment to the “Dual Carbon” goals (peak carbon by 2030, carbon neutrality by 2060), SCBC will continue to refine and expand this platform—adapting it to new materials and industrial contexts while exporting Chinese green innovation to the world.
