Presentation Title : Carbon Footprint of Recycled Solvents: Sustainability in Practice & Action

Abstract : This presentation will cover a carbon footprinting study that was commissioned by the European Solvent Recycler Group (ESRG) to assess the carbon footprint of recycled solvents produced by some of its members. The recycled solvents featured include mixed solvents, acetone, tetrahydrofuran (THF), methyl ethyl, ketone (MEK), triethylamine (TEA) and perchloroethylene (PERC). Life Cycle Assessment (LCA) has been used to estimate the carbon footprint, following the ISO 14044 methodology. CCaLC V3.0 has been used to model the system and estimate the carbon footprint. The study concluded that recycling of these solvents leads to significant savings of greenhouse gas emissions (ranging from 46-92%) compared to the virgin solvents. In addition, we will see how this methodology has been applied to support a substantial investment for the development of a solvent recycling processing chemical plant for one of the world’s largest chemical manufacturer.
