General Introduction

Increasing global concern about a lack of food, depletion of natural resources such as fossil fuels and minerals, environmental issues related to human activities, etc. has led to a growing interest in sustainable food production in harmony with the environment. In recent years, in many industrial fields, an increasing number of companies have been working on so-called zero emissions, such as reducing the amount of waste generated and recycling the waste as much as possible to reduce the environmental load.
