    Consulting report - Municipality of Surco: enhancing recycling through improved waste management system in the District of Surco, Perú
    (Pontificia Universidad Católica del Perú, 2024-10-09) Franco Quispe, Daelí Sonia; Hughes, Lisa Caroline; Pöltl, Stefan; Sánchez Paredes, Sandro Alberto
    Lima faces a significant waste management challenge, as large volumes of waste remain unsorted and improperly disposed of, resulting in environmental pollution, health risks to citizens and a general decline in public well-being leading to reduced trust in the actions of the municipality. The root cause is an inadequate waste management infrastructure that has not been properly adjusted to the growing population of the city which is further challenged by a restrictive regulatory framework that hinders the modernization of the entire system. The situation is further exacerbated by limited recycling efforts and a lack of public awareness on behalf of citizens and producers. This is partly due to the lack of education on waste separation and recycling practices. In other words, these frustrations result from a lack of cooperation between key stakeholders whose actions are not coordinated. The proposed solution is designed to be compact, affordable and easy to use. On the one hand, it offers a comprehensive waste separation system for households that can be easily inserted into the commonly used round waste bins to simplify recycling efforts. On the other hand, the proposed extension of producer responsibility based on a legislative change would force manufacturers to label their products with a sticker in a specific color (e.g., red star). In addition, matching colored waste bags which are specifically designed for the invented waste separation system will be produced and distributed to households by the municipality. As a result, the proposed solution requires actions from all key stakeholders (citizens, producers, and municipality), thus creating a collaborative ecosystem where waste management responsibilities are shared. In addition, the solution's intuitiveness eliminates the need for further instructions, thereby closing the critical gap in public education on waste separation practices and making waste separation a simple, everyday activity for citizens, thus tackling the problem directly at its source. Based on the designed projections, the expected impacts are twofold. The solution provides clear social and environmental benefits by improving public health and environmental conditions through the reduction of waste on the streets and in illegal dumpsites, consequently addressing SDGs 3, 6, 14 and 15. In addition, it allows to increase the low recycling rate of 10%, not only by extending producer responsibility, thus addressing SDGs 8 and 12, but also by educating citizens, thereby targeting SDG 4. Financially, the operations are projected to be economically viable based on the sales of the waste separation systems and the colored waste bags. With an estimated IRR of 42.10% and a positive NPV of PEN 165,728.14, the solution not only addresses a critical social issue and improves the quality of life for the citizens of Surco, but also promises strong financial returns which could even increase further thanks to the high potential of scalability by introducing the designed products in other cities with similar waste management problems.
