It is known as organic waste to waste originally from some living being. It is all the matter that has come from nature, and that no longer fulfills a defined function for people, but due to the characteristics that it has as natural it is very common that a reusable function is found. The most common is that organic waste are oriented to agriculture or to feeding and fattening animals.
The origin of organic waste can be domestic, commercial or industrial, and together they make up a very important portion of the totality of waste generated by societies, especially after the social processes of recent centuries, where industrial production and consumption multiplied on a planet that has constant physical limitations.
In this sense, reuse of organic waste It is very positive for the care of the earth, based on the double function of replacing a new product that should not be produced, and at the same time not generating the known trash, and with it the usual very large contamination that occurs in its accumulation. There are defined techniques for treating organic waste, and poor treatment can be very harmful to the environment: proof of this are hundreds of rivers and lakes contaminated around the world by natural waste.
The most common way to take advantage of organic waste is through the production of compost for the land, a supplement rich in nutrients that ensures and enhances the fertility of the soil: it is a simple task that can be carried out in the home itself, where the waste uses almost its potential for nutrients. Another treatment, somewhat more complex and delicate, is the production of gas with organic waste: decomposition under certain circumstances generates a particular class of gas, known as marsh gas.
The use of this waste is due to a strong discipline in consumers, who in the case of not practicing recycling on their own they must be educated to learn to classify waste between organic and inorganic. As many times recycling is not a profitable activity for companies, education in this sense is usually the task of public bodies.
