In the wave of agricultural green transformation, the feed industry is facing dual challenges of raw material shortage and environmental pressure. By using green synthesis and conversion technology, plant lipid biomass can be transformed into high protein feed, which not only solves industry pain points but also opens up a sustainable development path for resource recycling.
Traditional production has high energy consumption and prominent carbon emissions. At the same time, plant lipid biomass such as soybean oil and rapeseed oil by-products generated by the oil processing industry have been mostly incinerated or landfilled in the past, which not only wastes resources but also pollutes the environment. The emergence of green synthesis conversion technology has brought a turning point to this contradiction.
This technology uses glycerol and fatty acids from plant lipid biomass as the core raw materials, and achieves directional conversion through a coupled process of microbial fermentation and enzymatic hydrolysis. Unlike traditional high-temperature and high-pressure production modes, the entire process adopts biocatalytic technology, which directly reduces energy consumption by more than 40%. The R&D team has increased the protein conversion rate of plant lipid biomass to 85% by accurately regulating fermentation temperature, pH value and other parameters. The final output of the feed has a crude protein content of 55% -60%, and is also rich in nutrients such as amino acids and vitamins, with nutritional value comparable to imported fish meal.
In a large oil and fat enterprise, this technology has demonstrated significant dual benefits of environmental protection and economy. The enterprise generates over 50000 tons of plant fat biomass waste annually, which can be converted into 30000 tons of high protein feed per year, reducing the amount of waste landfill by about 48000 tons and reducing carbon emissions by 12000 tons annually. More noteworthy is that the wastewater generated during the conversion process can be recycled after treatment, achieving "zero wastewater discharge" and completely reversing the traditional image of "high pollution" in oil processing.
Applied to the feed application end, a pilot feed factory has reported that using plant-based biomass protein feed reduces production costs by 15% and improves the survival rate and growth rate of farmed animals. In the past, we relied on imported fish meal, which had large price fluctuations and unstable supply. Now, we use local raw materials for production, with controllable costs and in line with the concept of green farming. Our products are more popular among farmers, "said the person in charge of the factory.
With the advancement of the "dual carbon" target, the demand for plant lipid biomass protein feed continues to grow. Industry analysis shows that the compound annual growth rate of its market size is expected to reach 12% in the next few years, and it is expected to account for more than 15% of the protein feed market in a few years, which can reduce the dependence on imported soybean meal by about 8 million tons.
The green synthesis and transformation of plant lipid biomass from "waste" to "high protein feed" not only provides a sustainable raw material solution for the feed industry, but also connects the circular chain of oil processing and aquaculture industry. In the future, with the continuous optimization of technology, more agricultural waste is expected to be transformed into high-value resources, injecting lasting momentum into the green and high-quality development of agriculture.
