Xue Yuwei, Chief Economist of the China Urban Construction Research Institute, was invited to deliver a keynote speech titled &#8220;Food Waste Management and Case Studies,&#8221; offering a comprehensive presentation of China&#8217;s policies, technologies, and practical experiences in food waste management. This provided a &#8220;Chinese Solution&#8221; for organic waste management across Asia.<\/p>\n\n\n\n<p>Xue Yuwei highlighted that in 2023, the annual generation of food waste in major Chinese cities exceeded 82 million tonnes, accounting for 20\u201337% of total municipal solid waste. Improper disposal can lead to environmental pollution and public safety risks, such as the production of &#8220;gutter oil.&#8221; Advancing the segregation, resource utilisation, and safe treatment of food waste has therefore become a critical measure for achieving China&#8217;s &#8220;Dual Carbon Neutrality&#8221; goals and building an ecologically sustainable &#8220;Beautiful China.&#8221;.<\/p>\n\n\n\n<p><strong>I. Policy Guidance: Transitioning from &#8220;Safe Disposal&#8221; to &#8220;Resource Recovery&#8221;<\/strong><\/p>\n\n\n\n<p>China\u2019s food waste management policy has evolved from initial efforts to curb &#8220;gutter oil&#8221; and reliance on landfilling towards an emphasis on resource recovery. In recent years, the national &#8220;Dual Carbon&#8221; strategy has accelerated the introduction of supportive policies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The &#8220;14th Five-Year Plan for the Development of Municipal Solid Waste Classification and Treatment Facilities&#8221; sets a target for national daily food waste treatment capacity of 70,000 tonnes by 2025, with anaerobic digestion technology accounting for over 60%.<\/li>\n\n\n\n<li>The Ministry of Agriculture and Rural Affairs has banned the direct use of food waste as animal feed to prevent homologous contamination.<\/li>\n\n\n\n<li>The State Council\u2019s &#8220;Opinions on Comprehensively Promoting the Construction of a Beautiful China&#8221; emphasises establishing a fully integrated, closed-loop system encompassing &#8220;segregation\u2013collection and transport\u2013treatment\u2013resource utilisation.&#8221;<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>II. Technological Pathways: Diversified and Locally Adapted Approaches<\/strong><\/p>\n\n\n\n<p>China has established a diversified technological framework,&nbsp;<strong>dominated by anaerobic digestion<\/strong>, and supplemented by aerobic composting, biotransformation, and co-processing in waste-to-energy plants:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Anaerobic digestion<\/strong> accounts for over 80% of treatment capacity, converting organic matter into biogas for electricity generation or upgrading to bio-compressed natural gas (Bio-CNG), offering high energy recovery efficiency.<\/li>\n\n\n\n<li><strong>Aerobic composting<\/strong> is suitable for small and medium-sized towns, though it faces challenges such as low market uptake of the resulting compost.<\/li>\n\n\n\n<li><strong>Biotransformation technologies<\/strong> (e.g., using black soldier fly or housefly larvae) are well-suited for small-scale, distributed treatment systems, producing high-protein animal feed and organic fertiliser with high added value.<\/li>\n\n\n\n<li><strong>Compact, decentralised treatment systems<\/strong> are being rapidly deployed at county-level, reducing transportation costs and increasing operational flexibility.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>III. Benchmark Cases: Integrated Technology and Synergistic Park Models<\/strong><\/p>\n\n\n\n<p>Xue Yuwei presented several major projects designed or supported by the China Urban Construction Research Institute:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fuzhou Food Waste Project<\/strong>: Processes 500 tonnes per day using advanced systems including &#8220;pneumatic conveying, thermal hydrolysis, and impurity removal.&#8221; It enables biogas power generation, co-treatment of wastewater, and incineration of residues, achieving full-chain resource recovery. The project received the &#8220;First Price in 2023 Beijing Excellent Engineering Survey and Design.&#8221;<\/li>\n\n\n\n<li><strong>Beijing Gao&#8217;antun Food Waste Plant (2025)<\/strong>: Beijing&#8217;s largest dedicated food waste treatment facility, achieving over 90% grease recovery and generating 80\u2013100 m\u00b3 of biogas per tonne of waste. Integrated with photovoltaic panels, the plant reduces carbon emissions by approximately 38,000 tonnes of CO\u2082 equivalent annually, forming a multi-energy complementary system.<\/li>\n\n\n\n<li><strong>Yichang Food Waste Project<\/strong>: Employs an advanced process chain of &#8220;wet anaerobic digestion + MBR + nanofiltration + advanced oxidation,&#8221; achieving zero liquid discharge and reducing operational costs.<\/li>\n\n\n\n<li><strong>Suzhou Jingmi and Xi&#8217;an Jiemu Projects<\/strong>: Utilise &#8220;fly larvae engineering&#8221; and &#8220;black soldier fly&#8221; bioconversion technologies, respectively, to achieve high-value products. The Xi&#8217;an facility processes 100 tonnes per day, generating an annual revenue of \u00a521.9 million, demonstrating significant economic benefits.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>IV. Future Outlook: Advancing Towards High-Quality Development<\/strong><\/p>\n\n\n\n<p>Xue Yuwei outlined four key trends for the future of food waste management:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Technological Innovation<\/strong>: Scaling up biochar production for carbon sequestration, raising quality standards for digestate and biogas slurry, and promoting higher-value products.<\/li>\n\n\n\n<li><strong>Intelligent Management<\/strong>: Leveraging IoT and big data platforms (e.g. Chengdu&#8217;s GalileoOS, Terra Phoenix Group of Companies\u2019 Internet of Waste Things) for smart, real-time monitoring of the entire waste management process.<\/li>\n\n\n\n<li><strong>Policy Coordination<\/strong>: Improving cost-covering charging mechanisms and green finance instruments to strengthen incentives for resource-oriented projects.<\/li>\n\n\n\n<li><strong>Public Participation<\/strong>: Enhancing public awareness campaigns to improve waste segregation at source and promote green lifestyles.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"554\" height=\"311\" src=\"https:\/\/icycle-global.com\/wp-content\/uploads\/2025\/11\/ee724cb3a3a38d6f45144e78cf79e8e.png\" alt=\"\" class=\"wp-image-7156\" style=\"width:661px;height:auto\" srcset=\"https:\/\/icycle-global.com\/wp-content\/uploads\/2025\/11\/ee724cb3a3a38d6f45144e78cf79e8e.png 554w, https:\/\/icycle-global.com\/wp-content\/uploads\/2025\/11\/ee724cb3a3a38d6f45144e78cf79e8e-300x168.png 300w, https:\/\/icycle-global.com\/wp-content\/uploads\/2025\/11\/ee724cb3a3a38d6f45144e78cf79e8e-18x10.png 18w\" sizes=\"(max-width: 554px) 100vw, 554px\" \/><\/figure><\/div><\/div>\n<\/div>\n\n\n\n<p>The presentation, noted for its substantive content and illustrative case studies, was highly commended by attendees.
