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.

As the world’s fifth-largest emitter of greenhouse gases, Japan has set goals of cutting emissions by 46% by 2030 and becoming fully carbon neutral by 2050. Tackling food wastewill have to be a part of those efforts, Takahashi says.

    How many categories of trash/bag are there?

    Two, basically. Green one is for normal, yellow one is for food waste. Grey one is for recyclable stuff which I’ve never seen for myself which I assume is because there’s almost always a different company that handles them. There are some special bags for something like glass, dirt…etc which I have no personal experience with. But that’s just a bit fancier normal bag so only two it is: normal and food waste bag.

    Those kind of machines I’ve showed earlier are very common but only in big apartment complexes, which is, still, one of the most common housing in South Korea. If there’s no such machine near you, you’ll just have to buy bags for food waste.

    Trash collectors don’t really take a hard look at the contents but when it’s so obvious that there’s food waste in a normal bag, it’s about $100 fine for you and the garbage won’t get collected.

    But in reality, quite a lot of people do throw out food waste in a normal bag, not specifically because food waste bag is significantly more expensive(I’m not sure if it actually is more expensive or not. It’s such an insignificant amount of money for me to track) but because convenience.

    If you go shopping in South Korea, there’s a pretty good chance you’ll get plastic bag like this. This works as both shopping bag and normal waste bag. Pretty neat(although they tear easier than any other bags ☹)
