Dear all,
I have studied household food waste at univesity. We found that prevention of food losses led to a significant reduction in GHG emissions. Although composting and biogasification of food waste are good treatment methods, food losses prevention has higher GHG reduction potential.

Additionally, we found that "food waste separate collection program" could reduce the amount of waste. It suggest that the "visualization" is effective approach to reduce the household food waste.
So we need appropriate monitoring method. It will make possible to identify hotspots, measure the program achievement and visualize the information.
