Core Viewpoint - The article highlights the innovative "three-component separation" technology developed by Shenzhen Zhongnong Qimei Technology Co., Ltd., which transforms agricultural straw from a waste product into high-value industrial products, thereby addressing economic and environmental challenges in straw utilization in China [1][3][5]. Group 1: Technology and Innovation - The "three-component separation" technology allows for the complete decomposition of straw waste from nine major crops, converting it into high-value products such as pulp fibers and soluble humic acid, achieving zero waste and low energy consumption [5][9]. - Compared to traditional chemical methods for straw pulp production, this technology reduces energy consumption by 70% and water usage by 80%, with a straw utilization rate approaching 100% [5][10]. - The technology has been recognized as being at the international leading level, providing a viable "Chinese solution" for biomass refining [14][15]. Group 2: Market Potential - The bio-based fibers produced can replace pulp, with China's pulp consumption projected to reach 12.415 million tons in 2024, indicating a significant supply-demand gap [7][9]. - The soluble humic acid product serves as an organic fertilizer, offering a green and cost-effective alternative to existing mineral and biochemical humic acids [9][10]. Group 3: Industrial Development and Strategy - Zhongnong Qimei plans to establish multiple straw enzymatic hydrolysis industrial bases across China, aiming to process nearly 10 million tons of straw annually during the 14th Five-Year Plan period [17][19]. - The company advocates for innovation in mechanisms and the establishment of an industrial ecological alliance to enhance China's agricultural technology competitiveness on a global scale [19][20]. - The company envisions a dual-circulation resource pattern, integrating domestic networks with overseas production capabilities to lead a transformation in agricultural ecology [17][19].
金明杰教授:非粮生物炼制如何实现全链条创新?
Core Viewpoint - The article emphasizes the economic feasibility of converting non-grain biomass waste, such as straw, into high-value products through comprehensive innovation across the entire supply chain [2][4]. Group 1: Research and Development - Professor Jin Mingjie’s team at Nanjing University of Science and Technology has addressed key challenges in the biorefining process of lignocellulosic biomass, including high raw material collection and transportation costs, stringent pretreatment conditions, toxic byproducts, low bioconversion efficiency, and difficulties in lignin degradation [2]. - A novel pretreatment technology and biorefining system have been developed to solve critical issues in the biorefining process [2]. - The team has developed a high-solid enzymatic hydrolysis technology that achieves a fermentable sugar concentration exceeding 200 g/L, allowing for efficient fermentation of hydrolysate into products like cellulose ethanol, lactic acid, succinic acid, citric acid, and lipids without the need for washing or detoxification [2]. Group 2: Lignin Utilization - The research includes the analysis of lignin biodegradation pathways and the discovery of new lignin-degrading enzymes, employing a "biological funnel" strategy to construct multiple engineered strains for the efficient conversion of lignin into high-value products such as muconic acid and gallic acid [2]. Group 3: Company Formation and Impact - In 2024, Professor Jin Mingjie founded Suzhou Limi Biotechnology Co., Ltd. in Suzhou High-tech Zone, which has developed globally leading complete technologies with independent intellectual property rights, breaking through the industrialization bottleneck of converting non-grain biomass waste into high-value biochemical products [4]. - The establishment of this company is considered epoch-making in the field of biomass utilization [4]. Group 4: Industry Engagement - Professor Jin Mingjie is scheduled to present a report titled "Biorefining of Lignocellulosic Biomass Based on 'Sugar' Platform" at the 2025 Non-Grain Biomass High-Value Utilization Forum (NFUCon 2025) in Hangzhou, Zhejiang, from January 27 to 29, 2025, inviting industry participation for exchange [5].
