Abstract
AbstractThe main purpose of this study is to assess the environmental impacts of polyethylene terephthalate (PET) bottle-to-bottle recycling using life cycle assessment (LCA) methodology. Analysis was initially carried out using the material and energy flow analysis (MEFA), to assess material and energy efficiency of a PET recycling plant in Egypt using Umberto efficiency + software; followed by LCA using Umberto LCA software to assess cradle-to- factory gate of recycling post-consumer beverage bottles. The study has been conducted according to the ISO 14040/14044 standard. The functional unit is defined as 1 ton of recycled food-grade PET pellets. Depending on the cut-off approach it was discovered that the production of 1 Ton food-grade PET pellets results in 274 kg CO2 equivalent which achieves greenhouse gas emission of nearly 84%. Based on the study it can be said that PET recycling offers significant environmental benefits in-relation to virgin PET pellets production.KeywordsLife cycle assessmentCommodity plasticsPETRecyclingEnergy efficiency
