Abstract: Since the wastes discharged by food manufacturing industries are characteristically harmless and easy to recycle, they are commonly recycled into fodders and fertilizers. Because of this, food manufacturing industries in Japan are actively promoting zero-emission activities. This study aims at describing the characteristics of some of the leading examples of zero-emission activities in the food manufacturing industries in Japan. Based on a survey of the literature and of the information disclosed on corporate websites, we investigate the nationwide trend of zero-emission activities in food manufacturing industries, as well as the current state of recycling in beer manufacturing, seasoning manufacturing, and grain milling and flour manufacturing.
The findings of this study can be summarized into the following three points: (1) the number of enterprises achieving zero emissions has increased greatly in the food manufacturing industries after the Basic Law for Establishing the Recycling-Based Society was enacted in 2000; (2) in seasoning manufacturing and grain milling and flour manufacturing, there are some enterprises that have not yet achieved zero emissions; and (3) it was possible to survey the state of classifying and recycling wastes in each manufacturing process of these three types of food manufacturing industry and to show the differences among them.

Abstract: The purpose of this study is to describe the characteristics of community participation in non-industrial waste management (reduction, reuse and recycling) by local governments, residents and businesses in the cities of Nagoya and Osaka, based on statistical data and a questionnaire survey covering all municipalities in Japan.
The major findings of this study are as follows.
(1) In Nagoya, the volume of non-industrial waste has gradually decreased. Especially at the reduction stage, businesses participate in many local government projects to reduce non-industrial wastes and play the most important role in them. At the recycling stage, compared with the reduction and reuse stages, community participation is carried out by a variety of other entities.
(2) In Osaka, the volume of non-industrial waste has not decreased as much, and the ratio of non-industrial office waste has been extremely high. Moreover, there are very few local government projects to reduce non-industrial wastes in which businesses participate and cooperate at all stages.
(3) In Nagoya, as compared with Osaka, there are many local government projects to reduce non-industrial wastes and community participation is actively engaged in by various entities. Therefore, we can conclude that the reduction of non-industrial waste in Nagoya has been the result of community participation.
