A material that has already done its job or fulfilled its mission is disposed of as waste. Therefore, waste becomes useless and of no economic value to most people. These wastes can be disposed of, going to landfills or burial, or recycled for reuse.
In this Green Ecologist article we speak specifically about one type of waste: solid waste. Keep reading and discover what is solid waste and how is it classified to remove them properly.
The waste can be liquid, gaseous or solid. Under the name of solid waste is grouped only waste that is in solid state, leaving out those that are in liquid and gaseous state. The term is used urban solid waste to refer to those that occur specifically within urban centers and their areas of influence. These wastes are usually produced in private homes (houses, apartments, etc.), offices or shops.
Examples of solid waste they are a used paper, a plastic or glass bottle or a cardboard container. On the other hand, waste such as oil from a vehicle or smoke from a chimney are not classified as solid waste.
Solid waste can be classified into two large groups, hazardous and non-hazardous solid waste. Hazardous, as its name indicates, group those wastes that may pose a danger to citizens or the environment, due to their corrosive, explosive or toxic properties. While non-hazardous waste does not pose a danger to the citizen or the environment. These, in turn, can be subdivided into:
In addition to this classification, solid waste can also be grouped into organic and inorganic:
The urban solid waste management It is carried out in several stages: a first stage prior to collection (including separation and storage), the collection itself, the transport from the collection point and, finally, its disposal or transformation.
Once collected, the destinations of solid waste for disposal They may be:
The sanitary landfill is a method of eliminating solid waste that consists of depositing it on the ground, in a scattered and compacted way. This is mostly done with hazardous waste.
A waste incinerator is a system for treating garbage consisting of burning this waste at high temperatures, which reduces its volume by up to 90% and its weight by 75%. The disadvantage of this system is that it generates ashes, inert waste and gases that can be toxic to people.
This system classifies solid waste in the place where it is produced in order to later recover it. To recover them, processes, techniques and operations are applied that manage to give these materials the possibility of reusing them in their original or similar function.

The mismanagement of solid waste can have consequences, which we can consider really serious, such as:
