From an environmental and public health point of view, proper waste management in the stages that follow its generation allows mitigating the negative impacts on the environment, health and reducing pressure on natural resources. Reuse and recycling of materials are essential to reduce pressure on ecosystems and other sources of resources from which they are extracted. In parallel, the use of energy and water necessary for its extraction and processing is reduced, as is the need for space to finally dispose of waste.
Recycling aims to convert some of the materials that make up the waste (among the most important are paper and cardboard, glass, some metals and plastic) into reusable materials in production processes. From the point of view of waste management, recycling has the advantage of reducing the volume of materials that need to be collected, transported and disposed of at appropriate sites. The revaluation of waste also decreases the consumption of raw materials, electricity and water, among other inputs, which would be necessary for the extraction and processing of new materials.
