The concept of solid waste is the one that is applied to all types of waste or waste that humans generate from their daily life and that have a solid form or state unlike liquid or gaseous waste. Solid waste is the one that occupies a greater percentage of the total waste or waste that humans generate because a large part of what is consumed or used in daily life leaves waste of this type. In addition, solid waste is also the one that occupies the most space as it is not assimilated to the rest of nature and many of it remain for years and even centuries on the ground.
The current lifestyle of most of the world's population is based on the consumption of products and goods of all kinds that generate a significant percentage of solid waste due to having different types of containers, packaging and forms of presentation. Thus, from groceries to cleaning products, technological elements, clothing and many others are always presented and sold in packages normally made of materials such as plastic, glass or polystyrene, all elements that can be recovered but that take a long time to disappear. promoting then the constant collection of waste of all kinds. At the same time, many of these solid waste, such as batteries, metals or the same plastic, are extremely polluting for the soil, water and air.
The current problem of waste or solid waste is of great magnitude since this lifestyle mentioned, which is based on consumption, does not take into account the generation of new and more sustainable ways that make it possible to access the same elements. but without so many packaging. Many countries and localities have systems for the differentiation and recycling of solid waste in order to reuse it as far as possible and thus reduce the generation of waste of all kinds.
