The "4R" Rule

1

Restore

Waste is valued economically and becomes a secondary material (a process widely used in industry where one producer's waste becomes raw material for another.

2

Reduce

Reducing at the source is the primary choice in waste management, in the context of eco-sustainable production and consumption policies. Using fewer materials for a product is equivalent to reducing the extraction and processing of raw materials and, at the same time, the need for disposal.

Manufacturers are called upon to prevent or reduce the production of waste through the use of clean technologies and the design of clean products, i.e. products that are long-lasting, easily recyclable or reusable and can be disposed of without risk to the environment. Furthermore, initiatives for the reduction of packaging with the elimination of those that are superfluous also fall within the sphere of prevention.

The recyclability of a product arises even before the product itself and requires significant changes in design, choice of materials, production and distribution.

3

Reuse

Waste is reused without undergoing any transformation. Reusing the same product means increasing the use value of the asset and avoiding producing others to perform the same function.

4

Recycle

Waste is transformed into similar materials after special processing treatments.
