如何減少飲料容器對環境的影響


2

我想幫助一家酒吧(位於意大利米蘭)的所有者減少其產生的廢物對環境的影響。

我的目的是通過選擇包裝最可持續的產品,使他們購買相同的食品(尤其是飲料)。

他們給了我他們所購買產品的清單,以及每種食品含量類型的替代品。

packaging   content         recycling symbol    volume (l)
bottle      tonic water     triangle PETE 1     1.0
bottle      lemon soda      triangle PETE 1     1.0
bottle      coca cola       triangle PETE 1     2.0
bottle      coca cola       triangle PETE 1     1.5
tin         fanta           exagon ALU          0.33
tin         coca cola       triangle ALU 41     0.33
tin         lemon soda      exagon ALU          0.33
tin         chinotto        circle ALU          0.33

基於這些數據,如何設置分析?

估算包裝對我鎮的回收系統和環境的影響的最佳方法是什麼?

我應該使用openLCA還是可以使用一種更快捷但又不是太多的接近方式進行分析。

Have they considered post-mix soda/coke served in a glass? There's a significant up-front investment but in the long term it should pay for itself, but only if they sell a fair bit. I don't know how common this is in Italy, but it's the norm for pubs here in the UK. Pubs here do stock cans/bottles of less common soft drinks, as well as juices, but this would save a lot of packaging and disposal.

Dispensed premix is another option for smaller volumes, but I'm not familiar with it.
