A unique fermentation method being piloted in Japan transforms edible leftovers and scraps into sustainable feed for pigs.

Japan's small size and mountainous terrain present challenges for food self-sufficiency. The country imports almost two-thirds of its food and three-quarters of its livestock feed. Yet each year, Japan throws out 28.4 million tonnes of food – much of it edible.
This comes with steep environmental and economic costs. Compared to many countries, consumers in Japan pay higher prices for food because so much of it is imported. And they also pay taxes to cover the majority of the 800bn yen (£4.2bn/$5.4bn) the country spends each year on waste incineration. Food makes up about 40% of the rubbish that Japan incinerates, and incineration produces significant air pollution and greenhouse gas emissions.
I mean, I think the poster's point was that they had no leftovers because their parents forced them to eat it all with the given excuse. I had the same thing growing up.
If watching youtubers who raise hogs is any indication, anywhere between not caring at all to being enthused. Hogs are really not picky about their food for the most part and it's not uncommon to add liquid to the feed in general.
They've been doing this in Korea for more than a decade. It's a bit annoying being mandated to throw your food scraps out separately, but it's good to know the refuse is reused.
