Reducing Carbon Footprint of PET Films for Food Packaging Products Through Minimizing Solvent Consumptions

Abstract

Since solvents are used during the printing process of polyethylene terephthalate film, there are substantial environmental risks associated with this process. Solvents significantly increase the manufacturing process's carbon footprint. This abstract explains a comprehensive strategy to reduce solvent emissions in the production of PET films, in response to the industry's urgent demand for sustainable practices. The energy used in each unit to compute and convert carbon emissions into direct emissions is known as the "solvent usage" calculation; the electric carbon emission factor was used to calculate indirect emissions. Emission factor per day: 12 kg; direct solvent usage per day: 52.08 kg. It is not appropriate to use the Carbon Footprint as a means of making comparisons between various sectors, as various approaches and system limitations could be used. Solvents consumed during printing of PET films calculated because VOC compounds effects environment with high emission factor. Each colour’s volatile organic compounds were computed and converted to direct carbon emissions. The overall amount of greenhouse gases, mostly carbon dioxide and other pollutants, is referred to as a carbon footprint. The electric carbon emission factor and the unit usage of 2400 kg/kw on the press were used to determine the indirect carbon emissions. Carbon footprint calculations will help industries towards more sustainable and ecofriendly environment and green earth.
