  • Opportunities and challenges for food waste treatment enterprises

    In China, the sources of waste oil and fat are scattered, the procurement channels are complex, and the industry concentration is low, mainly for personal operation. According to the prospectus of Excellence New Energy, the company purchased more than 80% of waste oil from individual suppliers in 2016-2019; However, the price of waste oil purchased overseas is relatively low, but it can not enjoy the relevant tax rebate and subsidy policy. Therefore, domestic biodiesel enterprises do not take the overseas market as the main source of procurement.

    It can be seen that more and more kitchen waste treatment enterprises have begun to focus on the collection, treatment and sales of waste oil. For example, in addition to Shangao Huaneng, Wangneng Environment also proposed for the first time in its 2021 business plan to deepen the layout around waste oil collection and cooking waste oil extraction rate: on the one hand, it should do a good job in strengthening franchise rights, promote the construction of oil collection and waste collection systems, and explore the output of oil and fat operation services; On the other hand, we should continue to promote the improvement of the oil recovery process in food waste.

    Oily waste separated from catering can generally be divided into two types: one is general kitchen waste mixed with waste edible oil and kitchen waste, which can be separated by kitchen waste treatment enterprises through oil extraction; The other is the waste oil such as swill oil, frying waste oil and gutter oil, which are directly separated. After a series of processing, this part can form the terminal product "crude oil", which is often not the same as the general kitchen waste oil extraction line. In the past, food waste treatment enterprises not only faced the problems of low amount of oily waste and insufficient waste oil, but also faced the problem of low oil extraction rate.

    Focusing on the two key links of food waste collection and transportation and oil extraction, Shangaohuan can invest a lot of resources to carry out technological innovation and digital transformation. As of June 2022, the company has 122 patented technologies and more than 30 software copyrights, such as efficient pretreatment, new anaerobic treatment and high-value utilization of energy. For example, the digital solution for the collection and transportation of kitchen waste put into use in 2022, covering various scenarios such as collection and transportation point management, service platform, personnel management, vehicle management, data statistics, and so on, ensuring the full collection of kitchen waste and waste oil.
