Abstract

A methodology is proposed for taking recycling, an essential activityof the developed economies, into account within LCA tools. Thereasoning for choosing the methodology is exposed step by step.The final proposal is centered on the multiple-recycling model, whichbest describes the practical way that materials are actually recycledin the economy.
From a practical standpoint, the results obtained are attributed tosteel on the basis of a specific value (e.g. t of CO2 per t of steel),which amounts to averaging the impact over the various steps of therecycling process on a weighted average basis, depending on theamount of material recycled at each step.
