I would like to help the owners of a pub (based in Milan, Italy) to decrease the environmental impact of the waste they produce.
My intent is to make them buy the same food content (especially drinks) by choosing the products with the most sustainable packaging.
They gave me the list of products they buy, with some alternatives for each food content type.
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
Based on this data, how could I set up the analysis?
What's the best way to estimate what is the impact of a packaging on the recycling system of my town, and on the environment?
Should I use openLCA or is there a quicker and yet not too much proximate way to do the analysis.
