Waste less,
grow more.

As students at NUCB International College in Nisshin, we noticed a growing concern in our school community: food waste. Rather than simply accepting it, we decided to take action.

The UN goals we work towards

2
Zero hunger
11
Sustainable cities and communities
12
Responsible consumption and production
13
Climate action

Every single day, the average person in Japan throws away a full bowl of rice.

It's not just the food that gets wasted. Growing it used up water and land, and when it rots in a landfill it gives off methane, which is bad for the climate. These are the numbers that got us started.

4.64M
tonnes of food wasted in Japan every year
102g
wasted per person each day, about one bowl of rice
8-10%
of the world's greenhouse gas emissions
783M
people around the world still face hunger
