It is understood by trash that heterogeneous set of wastes, generally solid, that arises as waste material from different human or animal activities.
It is important to highlight the collective aspect of garbage, since we produce garbage together. Within this vast category, two types of garbage are known:
- Inorganic trash. It is the set of wastes that are not of biological origin. These are undoubtedly the ones that most pollute the environment, since having a synthetic composition, either total or partial, are difficult for microorganisms to degrade, so that they remain unchanged for much longer than other waste. Although households produce a certain amount of inorganic waste, it is industries that generate this kind of waste on a larger scale. For instance: glass, plastics, batteries.
- Organic trash. It derives mainly from the processing of food at home or at food venues. These wastes are more unpleasant but tend to be less problematic for societies, since being biodegradable, they decompose without major difficulties. They are even often used as organic fertilizers or in composting. For instance: paper, wood, dry leaves.
Classification of inorganic waste
Inorganic garbage is subdivided into two types:
- Recyclable. it can lead to a reuse process, which by the way is the most desirable.
- Non recyclable. the only way to address it and to avoid its negative impact on the ecosystem is by confinement in suitable containers, to avoid its indiscriminate dispersion by the environment. It is important to have adequate containers for the disposal of garbage in general and inorganic garbage in particular.
