On the 12th, a supermarket in Seodaemun-gu, Seoul. There was a food processor of regarding 200 liters in the corner of the kitchen in the fresh food corner such as fish and meat. From time to time, staff open the lid and put in food waste. The waste that has entered the processing machine is dried and decomposed, and is discharged into the sewer in a liquid state.

Not only the waste generated while processing meat, but also vegetables and fish, which are sold on the day, are thrown away if they cannot be sold. But I don’t know how much will be thrown away in a day. “I don’t know exactly what the emissions are. I’m recycling plastic packaging, but I’m not trying to reduce food waste,” said a Mart official.
There is a flood of food to be thrown away. The Food and Agriculture Organization (FAO) estimates that more than 30% of the $ 940 billion (regarding 1120 trillion won, regarding 107 trillion yen) food produced worldwide is wasted each year.

The amount of food-related waste discharged in Korea per day exceeds 20,000 tons. It weighs eight cups of water in the Olympic pool (2,500 cubic meters). However, the food waste problem has not received much attention since the pay-as-you-go emission system arrived safely regarding 10 years ago.

It means that all the people are throwing away the weight of a few Samgyeopsal every day.
In particular, a quarter of domestic food waste is thrown away before eating. Food waste from homes and restaurants decreased from 14,669 tons in 2016 to 14,548 tons in 2019.
