Resumen

This work presents a study on the reduction of single-use plastics in a neighborhood delicatessen, based on the application of sustainable accounting principles and Sustainable Development Goal (SDG) No. 12: Responsible Consumption and Production. Using an experimental and mixed-methods approach, direct observations, interviews, and surveys were conducted with owners, employees, and customers. Additionally, intervention strategies were implemented, such as charging for plastic bags, placing informative posters, and promoting reusable bags and returnable containers. The results demonstrated that the combined measures, especially charging for plastic bags and visual awareness, significantly reduced the use of disposable materials and fostered habit changes in consumers. Furthermore, limitations related to the low acceptance of returnable containers due to hygiene concerns were identified. In conclusion, the project confirms the feasibility of applying sustainable practices in micro-enterprises, showing that environmental responsibility and economic profitability can coexist in a complementary way, contributing to the transformation of consumption patterns and the fulfillment of global sustainability goals.
