Anaerobic Pyrolysis of Municipal Solid Waste

Anaerobic pyrolysis technology for sorted organic components of Municipal Solid Waste (MSW), commonly referred to as pyrolysis gasification technology, is an advanced thermal treatment method for solid waste. Its core principle involves heating pre-sorted and enriched organic waste (such as food waste, waste paper, plastics, rubber, straw, wood, textiles, etc.) to a specific temperature range (typically between 350°C and 800°C) under oxygen-free or strictly oxygen-deficient (oxygen-lean) conditions. Through thermochemical reactions, the large organic molecules undergo a series of complex processes including cracking, dehydrogenation, and polycondensation.

Physical Recycling Equipment for Positive Electrode Sheets

Henan Jufeng Technology Co., Ltd. has formed a powerful partnership with the Institute of Process Engineering, Chinese Academy of Sciences, and after ten years of dedicated research, they have successfully developed a physical dry-process repair and regeneration technology for lithium‑battery cathode sheets. This technology abandons traditional, low‑end crushing processes and instead addresses the industry’s long‑standing pain points—such as low recovery rates, structural damage, difficulty in direct reuse, and poor economic viability—through repair and regeneration.

Negative Electrode Sheet Recycling Graphite Regeneration Equipment

Against the backdrop of the “Dual Carbon” goals, Henan Jufeng Technology has addressed the industry’s longstanding pain points—namely, the “high‑temperature carbonization, structural damage, and difficulty in direct reuse” of spent lithium‑ion battery anode graphite powder—by abandoning low‑end pulverization processes. Under the leadership of Zhang Haitao, a member of Academician Zhang Suojiang’s team and doctoral supervisor at the Institute of Process Engineering, Chinese Academy of Sciences, Jufeng has joined forces with this team to develop advanced graphite regeneration technology.

Negative Electrode Graphite Repair and Regeneration

Jufeng Company, in collaboration with the Institute of Process Engineering, Chinese Academy of Sciences, has jointly developed a repair and regeneration technology for negative electrode sheets sourced from production scrap and batteries removed before electrolyte filling (unformed batteries). This technology achieves regeneration through a four-step process: anaerobic pyrolysis -> secondary graphite, acid washing purification -> primary graphite, carbon coating -> regenerated graphite, and microwave repair -> high-performance graphite. The performance of the graphite repaired and regenerated via this technology is close to, or even surpasses, that of virgin graphite.

Superheated Steam Decomposition of Municipal Solid Waste

As a core technical unit for the "Harmless Disposal of Municipal Solid Waste" project under the Ministry of Science and Technology's "13th Five-Year Plan" Key R&D Program, Henan Jufeng has conducted technical upgrades and improvements based on its subcritical water hydrolysis technology. The company successfully developed organic waste superheated steam decomposition technology. This technology can convert various organic wastes (such as food waste, animal manure, sludge, rural straw, industrial organic waste, municipal solid waste, garden waste, wet market waste, and other organic wastes) into organic fuel coal and combustible gas via superheated steam decomposition, achieving the goals of "zero pollution, harmlessness, and complete utilization."

Subcritical Water Decomposition of Municipal Solid Waste

Garbage Subcritical Water Hydrolysis Technology (Garbage Subcritical Water Pyrolysis) As a core technical unit for the "Harmless Disposal of Municipal Solid Waste" project under the Ministry of Science and Technology's "13th Five-Year Plan" Key R&D Program, Henan Jufeng was invited to collaborate with Huazhong University of Science and Technology to complete this project. Concurrently, after three years of iterative experiments, the company successfully developed the garbage subcritical water hydrolysis technology in 2021.
