Ebino City, Miyazaki Prefecture Eco-Feed Development Late 2000s
In the late 2000s, the reuse of food by-products and increasing feed self-sufficiency became important issues in Japan. This was against the backdrop of increasing food waste, the environmental impact of incineration, and the feed crisis caused by soaring grain prices in 2007-2008. Domestic livestock production, which is highly dependent on imported feed, was severely affected, and the development of domestic alternative feeds became an urgent task. The Ministry of the Environment and the Ministry of Agriculture, Forestry and Fisheries promoted the policy promotion of eco-feed, which utilizes food by-products.
Under these circumstances, a feed manufacturer in Ebino City, Miyazaki Prefecture, developed a fermented feed that combines fish waste with a lactic acid bacteria fermentation substrate. Fish waste has been treated as industrial waste because it is highly nutritious but easily decomposes, but the company has succeeded in improving safety and preservation by using fermentation technology to suppress odor and decay. The organic acid produced by fermentation lowers pH and contributes to improved hygiene and stabilization of feed ingredients.
In Ebino City, where the livestock industry is thriving, this technology was recognized as an environmentally friendly approach that supports farmers struggling with rising feed prices and promotes local recycling of marine processing by-products. With the Food Recycling Law and the development of safety guidelines requiring that eco-feed be safe, the development of local companies was also linked to national policy. The Yofurt Feed trial was a pioneering example of valorization of unused resources and regional circulation.
