On September 20, 2026, the pre-acceptance meeting of the Key Technology Project for Clean Utilization of Multi-source Low-cost Organic Solid Waste under the Joint Research Program for Ecological Protection and High-quality Development of the Yellow River Basin (Phase I) was held in Qingdao. Zhucheng Holy Shield Environmental Technology Co., Ltd. participated in the meeting as a project participant and developer of relevant supporting equipment.

Professor Zhang Jian, the project leader, and the project team members attended the meeting. The expert panel for pre-acceptance included Professor Sun Dezhi from Beijing Forestry University, Professor Chen Lvjun from Tsinghua University, Professor Liu Yangsheng from Peking University, Professor Li Fengmin from Ocean University of China, Researcher Zhu Ying from Qilu University of Technology (Shandong Academy of Sciences), Professor Bi Xuejun from Qingdao University of Technology, and General Manager Sun Qi from Qingdao Hi-tech Investment Management Co., Ltd.

Participants reviewed the completion of research tasks, development of key technologies and equipment, operation of demonstration projects, and achievement outputs. The expert panel listened to the project report and put forward suggestions on technical maturity, demonstration operation data, supporting documents of achievements, and follow-up promotion and application.

Meeting the Demand for Clean Utilization of Decentralized Organic Solid Waste

The Yellow River Basin covers a vast area. In some counties, towns and rural areas, domestic waste is generated in scattered sites with small volume at each point, long collection and transportation distance, leading to high costs for centralized disposal. Meanwhile, organic solid waste comes from various sources including domestic garbage, livestock manure, sludge, kitchen waste and agricultural residues, featuring diverse material properties and different treatment requirements. Balancing waste reduction, pollution control, energy recovery and stable operation is a practical challenge for decentralized organic solid waste treatment.

Led by Shandong University of Science and Technology, this project carries out systematic research on decentralized and small-scale clean thermal treatment of domestic waste and resource utilization of multi-source organic solid waste. Holy Shield is responsible for R&D, manufacturing and engineering implementation of related equipment, promoting the transformation of key technologies from laboratory research into complete sets of equipment and demonstration applications.

Operation of Demonstration Project in Ta'erhu Town

In Ta'erhu Town, Wuyuan County, Bayannur City, Inner Mongolia, Shandong University of Science and Technology and Holy Shield jointly built a 10 tons per day domestic waste gasification and heating demonstration project.

Targeting the small output and scattered distribution of domestic waste in county towns and villages, the project adopts small-scale gasification and heating equipment. It converts domestic waste into combustible gas for heating, realizing waste reduction while recovering energy.

Holy Shield participated in the manufacturing, installation, commissioning and engineering construction of demonstration equipment. During operation, both parties accumulated field data on material adaptability, equipment stability, gas quality, pollution control and heat utilization, providing practical support for equipment optimization and future project promotion.

Joint R&D Result Granted National Invention Patent

In terms of technological research, the integrated forming domestic waste gasification and energy supply device jointly developed by Shandong University of Science and Technology and Holy Shield has obtained a national invention patent, Patent No. ZL 2024 1 1656090.X. The patent owners are Shandong University of Science and Technology and Zhucheng Holy Shield Environmental Technology Co., Ltd.

The device optimizes structural design for key processes including domestic waste heating gasification, material stirring and gas export. It enables stable extraction of combustible gas for subsequent energy utilization, marking a phased achievement in the R&D of domestic waste gasification and energy supply equipment by the two parties.

University-Enterprise Collaboration to Promote Engineering Application of Technical Achievements

In 2023, Shandong University of Science and Technology established university-enterprise cooperation with Holy Shield and built a joint industry-university-research base. Since then, the two sides have continuously conducted joint research on resource utilization of solid waste, gradually forming an innovation chain covering technical research, patent layout, equipment manufacturing and demonstration application.

This pre-acceptance serves as a systematic inspection of project research tasks, technical achievements and demonstration applications, as well as a phased assessment of the effects of university-enterprise joint R&D and engineering transformation.

Next, in accordance with experts’ suggestions, Holy Shield will cooperate with the project team to further improve acceptance documents, demonstration operation data and achievement summaries. The company will continuously enhance equipment adaptability and operational stability for different materials, treatment capacities and regional conditions, get fully prepared for official project acceptance, and promote the engineering application of relevant technologies in clean disposal of organic solid waste in counties, towns and rural areas across the Yellow River Basin.
