Furthermore, this research project successfully developed for the first time an industrial-scale production line for the three-component separation of 10,000 tons of straw material per year, achieving a breakthrough from laboratory research to an original technology at an industrial level – a \"0 to 1\" advancement. It holds complete independent intellectual property rights for the innovative enzymes used in the decomposition of lignocellulosic straws as well as for the enzyme-catalyzed reactors. Compared with traditional chemical production processes, this industrialization pilot line reduces energy consumption (steam, electricity) by over 70%, saves more than 80% in water usage, and achieves a raw material utilization rate of nearly 100%. The experts of the evaluation committee unanimously agreed that this research project achieved core innovations in three areas: the development of new lignocellulose-degrading enzymes, the creation of new sets of enzymatic hydrolysis equipment, and the industrial-scale verification of enzymatic hydrolysis processes and equipment at a capacity of 10,000 tons. Through innovation across the entire \"enzyme-equipment-process\" chain, this research project has addressed the industry challenges associated with insufficient breakdown of components in straw utilization and low added value of the resulting products. The China National Light Industry Council stated that the achievements of this project \"provide a Chinese solution for biomass refining and hold strategic significance for achieving the ‘dual carbon’ goals.\" Chen Jian, chairman of the evaluation committee, an academician of the Chinese Academy of Engineering, and former president of Jiangnan University, spoke highly of this project: \"This project addresses the major needs of development by tackling the ‘bottleneck’ issues related to resources and industries. It promotes green, low-carbon, circular development and enables the recycling of resources; it is of great significance for fostering new forms of productive capacity. It serves as a model with demonstrative and leading effects.\" From an industrial perspective, to achieve high levels of autonomy and self-reliance in science and technology, it is first necessary to ensure control over industries. The significance of this project lies in its ability to replace imported foreign wood pulp and reduce pollution, carrying substantial economic and social value. ”
“Technological innovation and cross-sector collaboration are key to overcoming the cost issues associated with enzymes. ”Chen Jian pointed out that with the advancement of biologics and enzyme engineering technologies, it is now possible to develop more and better enzymes. Through cross-sectoral collaboration, including joint efforts by equipment manufacturing companies, industrial chains, capital chains, and value chains are established. Equipment is a crucial element in enzymatic hydrolysis technology; to integrate it effectively and drive overall technological progress, it is necessary to apply engineering thinking to refine the conceptual framework for project advancement, thereby creating **model solutions. Chen Jian said that the project needs to further expand its application areas, integrate into larger industrial clusters that are part of **development strategies and ecosystems**, focus on solving problems in industrial production, and establish a complete ecological industrial chain that includes both equipment and manufacturing processes. Sun Jibin, deputy director of the Tianjin Institute of Industrial Biotechnology at the Chinese Academy of Sciences, said: “If high-quality wood pulp substitutes can be developed, it will not only enable better utilization of straw but also reduce dependence on imports.” All the raw materials are utilized to the fullest, with no waste – everything is valuable, making commercialization highly promising. Tianshilí and Guotai Digital Wine Industry, leveraging their own advantages, will play a key role in facilitating the large-scale production of this technology as well as the intelligent transformation of the entire industry chain. ” Shenzhen Zhongnong Jiemei Technology Co., Ltd. has developed a high-activity biological enzyme technology for the efficient enzymatic breakdown of crop straws, utilizing synthetic biology to address this global technical challenge related to the scientific utilization of crop straws. It provides new technologies for the green and high-quality utilization of agricultural crop straws, opens up new pathways for the advanced development of such straws in Chinese agriculture, and offers the market a complete set of solutions with independent intellectual property rights.
Multiple benefits: Make the most of straw – in agricultural products, half comes from the seeds and half from the straw. However, even though they are the same resources, seeds are regarded as treasures, while straw is often discarded. At present, China’s theoretical straw resource amount is 977 million tons, while the collectible resource amount is 737 million tons, indicating abundant straw resources. Currently, straw is mainly utilized through methods such as returning it to the soil, generating electricity from it, using it to make boards, and converting it into organic fertilizer. However, these methods present issues such as low economic efficiency, severe pollution resulting from its use as an industrial raw material, high energy consumption, and high water usage. Therefore, replacing traditional chemical and physical treatment methods with enzyme-catalyzed techniques has become an important approach to achieving the green utilization of straw and efficient, clean production. How can straw be utilized more effectively? Some experts say that lignocellulose is the main component of agricultural and forestry waste such as straw, and the key to its value-added utilization lies in the efficient separation of cellulose, hemicellulose, and lignin (the three components). However, traditional processes suffer from severe resource waste due to issues such as low efficiency in component separation and the tendency of lignin to condense; therefore, the methods of utilizing straw must undergo a green transformation. Through a series of enzyme-catalyzed reactions, this research project can ultimately convert straw into fiber products, humic acid, and other products. Humic acid is an organic substance; when applied to fields, it can suppress the growth of weeds while promoting the growth of crops, thereby increasing yields. And fiber products—wood pulp—have always been important raw materials for industrial production. Some industry experts say that the papermaking industry is an important sector that relies on basic raw materials, yet China’s papermaking industry is facing a severe shortage of wood pulp. Due to limited domestic forest resources, China’s self-sufficiency rate in pulp production is low, resulting in a high dependence on imports; overseas giants hold the power to set prices. Therefore, in the field of pulp production, the utilization of agricultural residues is an important direction. Through enzyme-catalyzed reactions, this research project can ultimately convert straw into fiber products, which not only helps to address issues such as the low economic value of straw and environmental pollution, but also holds significant and far-reaching importance for **economic security and technological self-reliance**.
Therefore, in the field of pulp production, the utilization of agricultural residues is an important direction. Through enzyme-catalyzed reactions, this research project can ultimately convert straw into fiber products, which not only helps to address issues such as the low economic value of straw and environmental pollution, but also holds significant and far-reaching importance for **economic security and technological self-reliance**. Through years of technical research and development, Shenzhen Zhongnong Jiemei Technology Co., Ltd. has achieved significant breakthroughs in the utilization of straw. A responsible official from the company said that the three components of plant straws such as wheat straw, rice straw, cotton, and corn—fibers, hemicellulose sugars, and lignin—can be separated efficiently. The entire processing process relies on biological enzymatic hydrolysis; no chemicals are used, resulting in no chemical residues in the product. The production process employs clean manufacturing techniques; it represents **a green biomanufacturing technology that is actively promoted, generates no black liquor, and meets** environmental regulations. From an environmental benefit perspective, the first is reducing pollution caused by the use of straw. The outcomes of this project can effectively improve the utilization rate of straw, reduce the amount of straw burned, decrease the use of chemical reagents, and lower pollutant emissions. Secondly, it is to promote the recycling of resources. The lignocellulose-separated products from straw can be used to produce downstream products of bio-based fibers, enabling the recycling of resources and promoting sustainable development. At the same time, the separated enzymatic hydrolysate can be used as an organic fertilizer substitute to boost agricultural production and income, achieving a win-win situation in terms of ecological and economic benefits. From the perspective of social development benefits, on the one hand, the implementation of these projects fosters the development of industries such as rural straw collection and transportation, thereby promoting rural economic growth and rural revitalization as well as sustainable development in rural areas. On the other hand, the outcomes of these projects contribute to the technological advancement of the industry related to the comprehensive utilization of biomass resources, thereby enhancing the overall competitiveness of this industry. They provide strong support for achieving the **\"dual carbon\" goals and the strategy of sustainable development, holding significant social importance and strategic value. It is understood that it took over a decade of rigorous experiments for this technology to progress from an academic idea to its final industrialization. Among them, as strategic partners of Shenzhen Zhongnong Jiemei Technology Company, Tianshilu Group and Guotai Digital Intelligence Wine Industry Group played a vital role in helping to move these research projects from the laboratory stage to a production scale of tens of thousands of tons, assisting the research teams in refining the industrialization plans.
This is great news for the development of agriculture!
