Resumen
In this thesis, the sustainability of the recovery process of expanded polystyrene in Sibaté-Cundinamarca was evaluated. For this purpose, unit operations were established in the laboratory, with the purpose of projecting the pilot plant and estimating the financiery viability of the expanded polystyrene recovery process with the green solvent d-limonene, which comes from the orange peel. Next, the ACV Life Cycle Analysis methodology was applied to the two processes with and without recovery treatments, for this purpose the respective mass and energy balances were elaborated by unit processes of the system and the model was run with the help of databases data of the Open LCA software and finally the indicator IPCC 2013 and the Ecoindicator 99 were estimated as an ecological performance evaluation. It was found that the unit operations that generate the most negative ecological impacts are the final disposition in the sanitary landfill as it is currently done and the EPS production by the use of toxic reagents such as benzene, emissions and use of petroleum derivatives. In economic terms, there is a recovery of the investment in the first month and profits from the second. In the stakeholder analysis, which assessed the social dimension through the establishment of powers and interests and concluded that plastic recycling is more sustainable than its final disposition in the sanitary landfill, the actors involved in the process are the producers, consumers and sellers of plastic.
