A unique fermentation method being piloted in Japan transforms edible leftovers and scraps into sustainable feed for pigs.
Rachel Nuwer gets a firsthand look at a unique fermentation method being piloted in Japan to transform edible leftovers and scraps into sustainable feed for pigs while saving money, reducing waste and curtailing emissions.
Takahashi, who was then a practicing veterinarian, sensed an opportunity to put his farm animal expertise to use – and to simultaneously fulfill his desire to help the planet. As he learned more, though, he found there were no quick fixes, as simply sending raw food waste to farms was difficult.
Like the fermentation researchers who came before him, Takahashi was looking for a way, as Lee puts it, "to take what might otherwise simply be waste and transform it into something useful, in the process creating new industries."product for pigs. The team had to engage in lengthy troubleshooting. "When we fed the early test feed to the pigs, they grew slower and their meat was too fatty," Takahashi recalls.
The centre is located in Sagamihara, a city in Kanagawa prefecture that's about two hours by train from Tokyo. Sagamihara itself is unremarkable, but every year some 1,500 visitors from around Japan – from elementary students to retirees – visit the centre to learn firsthand about food recycling.
