Alpa Corral, in the South of Córdoba Mountains, is moving forward with a circular economy project that aims to turn the locality into a regional model of responsible waste management. The proposal, called “Alpa Corral Verde,” is promoted by the National University of Río Cuarto (UNRC) and aims to produce 10 tons of worm humus annually, as well as reduce solid urban waste generation by 30%.
The initiative includes a comprehensive system for waste management, with source separation, recycling, and proper disposal to minimize environmental impact. The Municipality and the IPEM 119 Néstor Zarazaga are involved in the plan, with a focus on environmental education as the driving force for change.
With around 2,000 inhabitants, the locality faces common challenges of small populations: limited infrastructure, scarce resources, and ingrained habits in a linear management model based on generating, discarding, and forgetting. This scheme is unsustainable in the face of population growth and pressure on landfills.
The project will be developed in three stages: diagnosis of the current situation, implementation of strategies —including workshops, technical talks, and composting with vermiculture— and finally control mechanisms to ensure the quality of the process and the produced humus.

Humus: a Natural Ally of the Environment
Worm humus is an organic fertilizer resulting from vermicomposting, a process in which worms transform organic waste into a nutrient-rich product. This material improves soil structure, increases its water retention capacity, and promotes the development of beneficial microorganisms for plants.
In orchards, gardens, and nurseries, humus allows cultivation with less dependence on chemical fertilizers, thus reducing water and soil pollution. Additionally, by reintegrating organic matter into the production cycle, it prevents large volumes of waste from ending up in landfills, where they would generate greenhouse gases.
Its commercialization can also represent an additional economic income for the community, promoting the local economy. Thus, humus is not only an environmental solution but also a tool for sustainable development.

Education and Community Commitment
It is estimated that 50% of the waste generated in Alpa Corral is organic, while the rest consists of recyclable materials such as plastics, glass, metals, and paper. The key to the project lies in training both the educational community and the treatment plant personnel, so that source separation is effective and the composting process maintains high-quality standards.
The UNRC, with extensive experience in waste and effluent treatment technologies, provides the necessary technical support to implement vermiculture on a community scale. Collaboration between institutions and residents is essential for the plan to be sustainable over time.
Beyond its environmental impact, “Alpa Corral Verde” aims to change the perception of waste, seeing it as a resource capable of regenerating soils, boosting local production, and strengthening ecological awareness. If citizen commitment is achieved, the locality could become a benchmark for sustainable development in the region and a replicable example for other communities.
