| Over the past 40 years of reform and opening up,the scale of China’s pig farming industry has been continuously increasing,and the contradiction between the economy,environment,and resources has also become increasingly severe.According to data released by the National Bureau of Statistics,the average annual output of fecal pollution in China’s pig breeding industry is about 1.8 billion tons,accounting for 47% of the total fecal pollution output of livestock and poultry farming;The comprehensive utilization rate of pig manure is less than 60%,far lower than that of developed countries.This high emission,high pollution,and high energy consumption pig farming model does not conform to the concept of sustainable development.The current pig farming industry chain urgently needs an energy-saving,environmentally friendly,and green and efficient development model.For China’s pig farming industry,it requires not only modernization,high efficiency,high quality,and industrial integration,but also low-carbon,environmentally friendly,recyclable,and sustainable.Therefore,it is necessary to achieve both industrial prosperity and ecological livability.With the proposal of "carbon peak" and "carbon neutrality" goals,as well as the development concept of "green production,green life,green development" deeply rooted in the hearts of the people,the concept of low-carbon pig breeding and recycling pig breeding has gradually attracted people’s attention and attention.In recent years,Inner Mongolia Zhengda Co.,Ltd.has developed a pig farming model throughout the entire industry chain,opening up a new channel for the resource utilization of pig waste through a combination of breeding and breeding,and strictly controlling product quality in accordance with international food safety and quality standards.This paper conducts research on the pig farming project of Inner Mongolia Zhengda Co.,Ltd.from a low-carbon perspective.Through on-site research,it fully understands the low-carbon development status of the enterprise’s pig farming project,collects key environmental information of the enterprise’s pig farming industry,and conducts in-depth analysis from the aspects of economic development level,environmental protection level,energy utilization efficiency,resource effective utilization level A comprehensive evaluation was conducted on the low-carbon development level of pig breeding projects from five aspects of waste utilization level.The expert scoring method and linear weighted sum method were used to determine the low-carbon development level of the project.It was found that the project has not yet fully achieved low-carbon development,with high levels of low-carbon in the economic development of the breeding industry and waste utilization,and low levels of low-carbon in energy utilization efficiency and effective resource utilization,The degree of low carbonization in terms of environmental protection is in the middle position.Summarize the shortcomings of low-carbon development in Inner Mongolia Zhengda pig breeding projects,such as the mismatch between the amount of manure returned to the field and the scale of crops,ineffective control of fertilizer and pesticide application,limited types of feed,low energy utilization efficiency,low resource utilization level,narrow application range of biogas,low low-carbon degree downstream of the industrial chain,limited independent innovation ability,and weak low-carbon awareness among workers.Targetedly propose to carry out in-depth actions to save medicine and fertilizer Suggestions for promoting low-carbon development of pig farming include upgrading feed,improving land resource utilization and efficiency,improving energy utilization efficiency,expanding the application of biogas,improving the low-carbon farming industry chain,and enhancing employees’ low-carbon awareness.Planning and constructing modern low-carbon pig farming projects with more prominent ecological benefits,significant economic benefits,and social benefits can help other regions and pig farming enterprises in China develop low-carbon Provide reference cases for environmentally friendly and sustainable aquaculture industries. |
