Although waste and garbage are perceived as the same thing among the people, the two terms are different from each other. According to the waste management regulation published by the Ministry of Environment and Urbanization, waste is defined as "any substance or material that has to be disposed or discarded or left to the environment by the producer or the real or legal person who actually owns it". Garbage is called substances and materials that cannot be recycled in any way.
Waste Management is carried out according to the steps called "Waste Hierarchy". The first and most important step is Prevention / Mitigation. Other steps are the steps of creating recovery, recycling and reuse methods, respectively. For wastes that do not fall into any of these steps, the last step is energy recovery and disposal steps.
Prevention / Mitigation / Reuse:
In order to protect natural resources, to provide energy and financial savings, the necessary steps are taken to extend the life of supplies and materials in the manufacturing processes and to ensure that they are suitable for reuse.
At this stage, the products are processed and used as other products, materials for different purposes. Thus, the need for new raw materials is reduced.
In this step, which is similar to the recycling step, it is aimed to obtain energy from waste in addition to new products.
It is the transformation of non-recyclable waste materials into heat, electricity or fuel through different processes.
In the last step, it is aimed to eliminate the wastes that cannot be passed through the above steps. The sending of wastes to landfills is one of the most common disposal methods.
