Based on the "Prevention is the best cure" principle, the triptych / motto "Reduce, Reuse, Recycle" has been created. How can we talk about waste management if first we do not care to reduce their production? The first step is therefore to reduce the use of any resources, then try to reuse them wherever possible, and finally to reject them for recycling. Along with the ecological benefit, this triptych / motto also brings economic benefits to industries where operating costs are anyway big. With a careful planning, they can be reduced if there is a proper and not irrational use of existing resources.
