Propuesta de actualización a los programas del PGIRS de Chía, Cundinamarca

Abstract

This work presents a proposal for updating the Integrated Solid Waste Management Plan (PGIRS) of the municipality of Chía, Cundinamarca. It is based on the methodological framework established in Resolution 0754 of 2014 for the formulation, implementation,evaluation, monitoring, control, and updating of PGIRS. The update proposal was structured in three phases: (1) Updating the baseline, which allowed for a characterization of the municipality's current situation regarding solid waste management, using economic, social, environmental, technical, and operational parameters, based on secondary information obtained from local entities. (2) Identifying key issues in integrated solid waste management through a cause-and-effect analysis (represented in a problem tree), followed by the prioritization of these issues. Objective trees were also developed as a basis for resolving the identified problems. (3) Updating the PGIRS programs, taking into account the regulatory framework, diagnostic changes identified in the baseline, the identified problems, and the defined objectives. This also considered the existing programs and projects in the current PGIRS of Chía, including verification methods and risk identification for each project within the thirteen programs established by Resolution 0754 of 2014. The proposal also includes a timeline and financial plan. Despite institutional efforts, recovery levels remain low, and a high proportion of waste (78% of total generated) continues to be disposed of in the sanitary landfill. Structural causes were identified, such as lack of inter-institutional coordination, insufficient planning, weak public awareness, and limited coverage of educational campaigns. The operational instability of recycler associations was also noted, along with the need to strengthen their sustainability and inclusion. A total of 13 programs and 17 projects were developed, including three programs that were not included in the currently valid PGIRS of the municipality, prepared in 2015. This update proposal responds to changes in population, economic, and environmental dynamics experienced by the municipality, thus reinforcing integrated solid waste management in all aspects defined by current regulations. It emphasizes the importance of expanding service coverage in various areas of waste management and structurally strengthening the waste recovery system.
