The issues addressed in this research are closely linked to the concepts of environmental and ecological sustainability and Reduction, Reuse and Recycling, words that have for some time been on the political agenda of most countries.

If the hierarchy of the "4 Rs" (Reduce, Reuse, Recycle and Recover), the order of priorities recognized in Europe, can be considered the starting point, a significant contribution has come from economist Serge Latouche, who has dealt with these concepts in his writings on "society of degrowth", introducing more interdependent goals to strive for, other "Rs", to reach a total of 8, which is shown below.

1. Re-evaluate
Review the values ​​in which we believe and by which we organize our lives.

2. Re-conceptualize
Modify the conceptual and emotional context of a situation in doing so completely change its meaning.

3. Re-structure
Adapt the economic-production structures according to changing values, consumption patterns, social relationships, lifestyles, so to guide them towards a society of degrowth.

4. Re-localize
Essentially consume local products produced by companies supported the local economy. Consequently, any decision of an economic nature can be taken on a local scale, for local needs. In addition, if the ideas must ignore borders, the movement of goods and capital are required to be reduced to a minimum.

5. Re-distribute
Guarantee to all inhabitants of the planet access to natural resources and equitable distribution of wealth, ensuring a satisfactory job and decent living conditions for all.

6. Reduce
Both the impact of the way we produce and consume on the biosphere and our working hours. Resource consumption is reduced up to until it goes back to an ecological footprint equal to a planet.

7. Reuse
Repair equipment and goods for use instead of throwing them in a landfill, thus overcoming the obsession of the obsolescence of objects and the continued "strain toward the new", functional to the society of consumption.

8. Recycle
Retrieve all non-decomposable waste arising from our activities.

The European Directive 2008/98 of the EU has integrated this hierarchy further, deepening the concept of reuse and introducing the definition of preparation for reuse.

 Reuse means any operation by which products or components that are not waste are used again for the same purpose for which they were conceived.

Preparation for re-use: control operations, cleaning, disassembly and repair by which products or components of products that have become waste are prepared so that they can be re-used without any other pretreatment.
Preparation for re-use and re-use processes are configured so as to "repair" old products or components thereof (and differentiate from each other what constitutes waste or non waste): the object produced, in both cases, is characterized by having the same function as the original product.

From these two practices instead the so-called Creative Reuse is differentiated, which is the object of the present research, and that we propose as a sort of "ninth R".
Creative reuse is essentially an artistic-artisan practice used to indicate the manipulation of waste, and byproducts in general, in order to create new objects of common use.
Creative reuse differs from reuse because the first is a commonly understood action, which has its roots in the famous Dadaist gesture of the ready-made (or found object) by Marcel Duchamp, the "resuscitation" of objects that acquire a new function, becoming in effect new products.
Creative reuse, therefore, appears to be tied to an artistic concept and is widely used in design as a virtuous practice.
The need that designers and artists today perceive as urgent is that creative reuse, like reuse and preparation for reuse, is to be understood, defined and regulated in the regulatory framework so that it falls into the category of recovery, thus enhancing its utility.

In our opinion, a starting point to build a definition of creative reuse may be this:
"A recovery operation by which products, components, waste and by-products are handcrafted, also on a large scale, in order to obtain products or materials to be used with a different purpose than that for which the original product had been conceived. As a rule, the distinctive character of this operation will be the recognition of the original object as being a part of the new product. "
In light of the definition of Preparation reuse, it should be noted that if the products, components, waste and by-products have already been classified as waste, it becomes necessary that they be subjected to some type of control operation, cleaning, removal or repair, before be reused in a context of creative reuse.
