On September 26, 2025, the inspection team of the WIPO GREEN City Acceleration Project visited the CNOOC Building in Chaoyangmen, Beijing, to conduct an on-site inspection of the kitchen waste treatment project. This project was introduced by the NOOC Enterprises Co., Ltd. Headquarters Comprehensive Service Branch (hereinafter referred to as the "Headquarters Comprehensive Service Branch") in collaboration with Beijing Zhongyuan Chuangneng Engineering Technology Co., Ltd. (hereinafter referred to as "Zhongyuan Chuangneng"). Members of the inspection team included Peter Oksen (Head of Green Technology and Research at WIPO GREEN), Deng Yuhua (Counselor of the WIPO China Office), Xie Hongxing (Director of the Bluetech Clean Air Alliance), and Zhou Yuguang (Chairman of the Supervisory Board of the Bluetech Clean Air Alliance). Xiao Zheng (General Manager of Zhongyuan Chuangneng) and relevant persons in charge of the Headquarters Comprehensive Service Branch provided on-site briefings on the project.
On March 6, 2023, the "Carbon-Neutral" Building of the CNOOC Building in Chaoyangmen was officially unveiled, becoming the first central enterprise headquarters "carbon-neutral" building certified by the Beijing Green Exchange. The CNOOC Building in Chaoyangmen has approximately 1,500 permanent staff and generates around 1,200 kilograms of kitchen waste daily. The Headquarters Comprehensive Service Branch actively participated in the Beijing Pilot of the WIPO GREEN City Acceleration Project. With the recommendation of the Bluetech Clean Air Alliance, it conducted green technology matchmaking with Zhongyuan Chuangneng and finally procured an aerobic fermentation treatment equipment with a daily processing capacity of 2 tons. Since the equipment was officially put into use in 2024, all kitchen waste generated by the CNOOC Building has been effectively treated by this equipment.
This project has an annual kitchen waste treatment capacity of 310 tons. Compared with incineration treatment technology, the adoption of aerobic fermentation technology can achieve a carbon emission reduction of 60 tons per year. It is estimated that the project can produce 43.8 tons of organic fertilizer annually, which can be used for the cultivation of 73,000 potted flowers and green plants. The annual carbon sequestration of the project reaches 57.4 tons, equivalent to planting 3,190 trees. Currently, part of the produced fertilizer is used for the maintenance of green plants in the park; part is distributed to customers for flower cultivation during waste classification activities; and another part is transported to the park’s vegetable planting base in Future Science and Technology City. The vegetables grown there not only return to the staff canteen but are also sold to employees, truly realizing the closed-loop utilization of kitchen waste—turning "waste into treasure".
In April 2020, Beijing revised the Beijing Municipal Domestic Waste Management Regulation, putting forward more systematic requirements for waste classification, collection, and disposal. In September 2021, Beijing further issued the Notice on Adjusting Matters Related to Non-Residential Kitchen Waste Treatment Fees in This Municipality, which set new requirements for kitchen waste treatment in large-scale catering establishments and encouraged on-site treatment. If on-site disposal is not feasible, the waste must be entrusted to qualified institutions for special collection and treatment. This not only increases the cost of off-site disposal but may also lead to delayed waste removal due to the limited number of qualified institutions, resulting in environmental sanitation issues. Against this background, the Headquarters Comprehensive Service Branch actively sought effective on-site kitchen waste treatment technology solutions.
In 2021, the Bluetech Clean Air Alliance, in cooperation with the World Intellectual Property Organization (WIPO) and the Beijing Municipal Intellectual Property Office, launched the Beijing Pilot of the WIPO GREEN City Acceleration Project, which built an important platform for finding solutions to Beijing’s green challenges. With the facilitation of the pilot working group, staff from the Headquarters Comprehensive Service Branch participated in the acceleration activities of the City Acceleration Project, learned about Zhongyuan Chuangneng’s outstanding application cases in the field of kitchen waste management, and conducted discussions with the Zhongyuan Chuangneng team, eventually reaching a cooperation intention. The successful implementation of this project also marks the fourth project landed under the Beijing Pilot of the WIPO GREEN City Acceleration Project.
As China’s capital and a science and technology innovation center, Beijing has become the first WIPO GREEN City Acceleration Pilot launched by WIPO globally. Centered on Beijing’s green challenges, the pilot conducts demand research and collection of green technologies, and recruits green technologies from around the world based on these demands to promote the on-site application of technologies in the city and accelerate urban green development. The Bluetech Clean Air Alliance is the implementing agency of the Beijing Pilot. After 4 years of operation, the Beijing Pilot has achieved fruitful results: a number of demand-technology matchmaking successes have been realized, four projects have been landed, and a series of acceleration activities have been carried out, including green technology intellectual property training, the China Green Technology IP Strategy Acceleration Camp, financing matchmaking, and green technology achievement transformation.
