• Abstract:

  Globally, the production of synthetic polymers doubled from 2000 to 2019, reaching 460 million tons, which represents 3.4% of global greenhouse gas emissions. This is why we seek to replace synthetic polymers with biopolymers, made from organic solid waste that lead to sustainability and sustainability in processes at an industrial level. This work aimed to study the mechanical and economic advantages of producing biopolymers from orange peel modified with graphene. With respect to properties such as: tensile strength, water vapor permeability and water solubility, there were no significant differences with and without graphene. The percentage of elongation in biopolymers with graphene was favored 2.3 times and the Young's Modulus was 2.1 times higher in biopolymers without graphene. In the economic study, it was determined that the sales price of biopolymers without and With graphene was 12 and 1000 times higher than the sales price of synthetic polymers, however, when considering the cost of the environmental impact that is reflected for a government In the disposal and storage of waste, the cost of synthetic polymers rose from a thousand to a billion times more depending on the time it takes for the polymer to degrade, resulting in an opportunity cost for biopolymers that takes up to 5 years. in degrading.
