Dear all,
I am doing an LCA of packaging systems in SimaPro using ecoinvent 3 (mainly consequential library). I am struggling to find a waste treatment process for cardboard, for which the desired process is recycling. What process would you recommend?
Thank you in advance,
Dear, be aware that the results of an LCA are very inaccurate and are depending of a lot of assumptions. The recyclingschemes vary from situation to situation and from country to country. I suggest that you make your calculations for the different types of processes and than you also have an impression of the accurrancy of the calcullation method. It is so important to give the standard deviation of the results. As a designer we use qualitative tools based on ecodesign rules of thump which are related to the principles of the circular economy. Paper is worse than pure PE. Cutting trees take away the carbon sink. A small tree that is planted in place of the big tree does not have the same CO2 up take. Paper might have the impression of being more sustainable than plastic but it is not. Good luck

Start with the resourcing of raw materials for cardboard along with fuel usage and energy consumption. I would like to recommend you the B-Sat tool which has simple interface for data input such as life expectancy, vehicle type and distance of transport etc.
