A CONCISE OVERVIEW OF THE SOLVENT AIDED SEPARATION AND EXTRACTION BASED ON THE PLASTICS WASTE

Abstract

Although technological advancement has been a boon to modern science, somehow it has also been the necessary evil in terms of scientific developments. A research conducted by Barba and Guitierrez in the year 2008 highlighted that most of the waste plastics are landfills or incinerations [1]. Furthermore, 87.6% of the same is contributing to the number of toxic pollutants generated from plastic waste [1]. The average global plastic recycling rate is only about 18% which is much below the standardized numerical figure of around 73.2%1. Since the advent of the first synthetic plastic, the usage of plastic has grown dramatically and is containing to increase. This primarily results in overconsumption, disposal, and littering of plastics which ultimately causes in pollution, thus causing serious environmental hazards. Despite there are several plastic recycling technologies that have been proposed over decades, the recycling sector stills face the challenge because of several technical difficulties involved within the recycling method and relatively insufficient profits, especially in mixed plastics [2].
