I have just seen the “recycling bottle” in the courtyard of pavilion D at our university. It is an excellent initiative to make us reflect on the environmental benefits of so-called recycling, i.e. the collection of waste materials that can be reused again, after technical or technological procedures.

That is why we must practice – with the so-called garbage (or solid waste) – the 4 R’s: reduce, reuse, recycle and recover. Recycling, as UNEP (United Nations Environment Program) says, is an effort that works and protects our environment.

What is recycling recovery

An alternative “R’s” could be, in addition to Reduce, Recover, and Repair, Recirculate; that is, donate to others who can use it, all this, before recycling the material, since it implies generating an expense and energy consumption.

Recovery occurs after recycling. Just as recycling consists of separating the “garbage” so that it can be used, recovery involves obtaining energy from the “garbage” that cannot be used. The example of the bicycle refers to the concept of reuse, since a second use is given to an object whose basic function has ended.
