Abstract
This paper focuses mainly on two topics: principles to be implemented for utilizing more renewable resources and measures for preventing waste generation based on a 3R approach. For the sustainable use of renewable resources, it is important to maintain a situation whereby the utilization rate for renewable resources never exceeds the rate of their production. In addition, the waste generation rate must stay within the natural ecosystem’s capacity to receive it. From a long-term perspective, the use of exhaustible resources must be controlled by tight waste prevention measures, while a societal shift centered upon greater use of renewable resources needs to take place. We must create a society that can sustain itself through a product lifecycle flow that cuts out all avoidable waste generation. The importance of waste prevention has now been widely recognized, and in particular food waste prevention has become a specific point of discussion. It is said that 1.3 billion tons of food is lost or wasted every year around the world. On the other hand, it is reported that most of this is avoidable. This amount of food waste is the cause of higher GHG emissions. Research now shows that approximately 1 ton of GHG emissions can be lowered with each equal 1 ton of food waste reduction.
