Carbon dioxide emission associated with the production of plastics - A comparison of production from crude oil and recycling for the dutch case
Environmental Engineering and Management JournalVol. 8Nr. 4
Abstract Literature data show that in general, plastics produced through the mechanical recycling route involve less carbon dioxide emission than when produced from crude oil. A review of readily available data shows that road transport of untreated waste plastics account for a significant portion of the carbon dioxide emission generated during recycling. Therefore, much carbon dioxide emission can be saved by optimizing the logistics in the recycling of plastics. On the example of polyolefi...
