牛乳パックリサイクルの環境負荷評価

抄録

Environmental impact by recycling paper package for milk products (milk pack) was estimated using environmental I/O table in Japan. Present state of recycling technology and materials flow was also investigated. Production of 7.66×10⁵ton toilette paper (1997 in Japan) was considered using recycled 2.001×10⁵ton of milk pack (1997 in Japan) in function of recycle rate. In case of using PE coating film on milk packs for thermal energy in recycle process the impact becomes reduced with increasing recycle rate of milk packages.
