**5. Conclusions**

Waste-free design, accordingly to circular principles, can help ensure that we secure enough resources for our society's development. This need to combine environmental, social, and economic vectors of sustainability may be considered from different perspectives, but the literature shows some common grounds.

Circular value creation is recommendations at a business model level that suggest the use of one or more strategies to close, slow, or narrow resource loops. Several strategies were identified, such as recycling, repairing, remanufacturing, and reusing.

From a social perspective, it is expected that the new retailer options will be characterized by a better environmental profile than its contemporaneous, ones in order

for the same service — making goods available — to be made accessible with a smaller environmental burden.

Design solutions that drastically optimize the resources involved in the products, by simplifying the role played by manufacturers, distributors, retailers, and users, promote an increase in the number of cycles of use of the plastic product, as well as increasing the percentage of recovery for recycling.

Ultimately, from general design parameters, innovation in products has to emerge, taking into consideration human aspirations and worries, characteristics from the design process.
