On January 31, 2025, the research results of Chairman Lin Shuguang of Qingdao Zhonghai Environment and Professor Huang Guangqun of China Agricultural University and their team were published online in Bioresource Technology, an academic journal ranked first in the field of international agricultural engineering. The thesis is entitled "Membrane - covered aerobic composting mitigated nitrous oxide emission through improved micro - aerobic state and so on. enhanced carbon source utilization ", this research result successfully revealed the nitrous oxide emission reduction mechanism in the mulched aerobic composting process, providing an important theoretical basis and practical guidance for the green development of agriculture.
Scientific research breakthrough
In-depth analysis of emission reduction mechanism
As a potent greenhouse gas, nitrous oxide emission in agricultural production, especially in composting, has attracted much attention. Covering selective transfunctional membrane (MCAC) reduced nitrous oxide production by more than 20% in aerobic composting process, and increased the aerobic layer by 24%-27% to increase the utilization of carbon sources by microorganisms. This means that when we deal with aquaculture waste, we can not only achieve effective use of resources, but also greatly reduce the negative impact on the environment, and take a solid step toward the goal of green and low-carbon.
Industry-university-research cooperation
Strong backing helps scientific research take off
Behind this outstanding achievement, it is inseparable from the strong support of close cooperation between industry, university and research. The professor workstation jointly built by Qingdao Zhonghai Environmental Engineering Co., Ltd. and China Agricultural University provides a high-quality platform for scientific researchers to exchange and cooperate. The combination of practice and theory makes the successful application of laminating aerobic composting technology, which provides an efficient and environmentally friendly solution for the treatment and utilization of aquaculture manure. It is believed that in the future, with the continuous promotion and improvement of this technology, more farms will be able to achieve green and low-carbon transformation, contributing to the protection of our ecological environment and promoting the sustainable development of agriculture.
