平成13年に食品リサイクル法が施行され, 今年が再生利用などを義務付けた目標年度にあたることを踏まえて, 食品廃棄物リサイクルの動向を検証する。<BR>現在, 食品産業全体から排出される食品廃棄物の約50%が再生利用され, その多くが肥料・堆肥あるいは飼料へ転換されている。その反面, 肥料・堆肥の利用先である農地は減少を続けているため, 今後堆肥・肥料の供給過剰が予想される。<BR>資源循環のコンセプトはリサイクルではなく, 持続可能性にあることから, 食品廃棄物も再生利用の向上ばかりではなく, 発生抑制を最優先に進ある必要がある。そのためには, われわれの食生活やライフスタイルを見直すことが今後一層重要になる。
With 2006 marking the target date for recycling obligations adopted under the Food Recycling Law of 2001, we are looking into trends in the recycling of food waste products.<BR>Currently, around 50% of waste products from the entire food products industry get recycled ; with most food waste being converted into fertilizer, compost, or material for animal feed. In addition to food waste, a growing amount of other kinds of organic waste, such as livestock manure and wastewater sludge, are also being recycled into fertilizer and composting material. In spite of this however, as the area of agricultural land to use such recycled material shrinks, oversupplies of compost and fertilizer can be expected in the future.<BR>Despite the use of recycled material gaining traction, efforts to restrict and reduce waste during production processes are generally lagging behind. The concept of resource recycling is not just about recycling; rather, the idea of sustainability holds that waste products need to be first reduced at the source, without solely relying on improvements in how food waste is recycled.<BR>In the end, it is our very own eating habits and lifestyles that have a huge impact on the origins of food recycling issues. Here in Japan, there is an approximately 30% oversupply of food in terms of the calorie base of the country, which means our eating habits are inevitably structured to produce massive amounts of food waste. Consequently, dealing with food recycling issues requires not only recycling of the waste, but also making improvements to our eating habits and lifestyles based on the keywords and concepts of "food safety" and "local production for local consumption."
