Plastic pollution is one of the biggest environmental challenges of the 21st century, causing potential damage to ecosystems and human health, with an increasing need to find solutions to minimize these impacts. Solvent-based dissolution and precipitation is a promising approach for plastic waste recycling, and the need to find green solvents is emerging. In this sense, this study was conducted to identify suitable solvents for a dissolution/precipitation process aimed at recycling a mixture of plastic waste, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), and polystyrene (PS). The selection of solvents considered their dissolution properties, low environmental impact and absence of harmful effects on health, as well as their origin from bio renewable sources. Based on these criteria, nine solvents were selected to validate the dissolution conditions of plastic waste, namely, temperatures and dissolution/precipitation time. The solvents tested in the laboratory were: Cyrene™ for PVC; Dimethyl isosorbide (DMI) for PET and PVC; Anisole for PET; d-Limonene for PE and PS; 2-Methyltetrahydrofuran for PS; Eucalyptol for PE and PS; Cumene (Isopropyl Benzene) for PE, PS, and PP; 1, 2, 3, 4-Tetrahydronaphthalene for PS; and p-cymene for PE and PS. The results enable us to propose a dissolution/precipitation treatment sequence for separating a plastic mixture in the following sequence: addition of p-cymene to dissolve the HDPE/LDPE and PP, addition of 2-Methyltetrahydrofuran to dissolve the PS, and addition of Cyrene to dissolve the PVC. In this proposed method, the PET remains isolated and can be recovered without adding solvent.
