It is possible to modify the general public's perception in favour of prevention and reuse, by using communication strategies based on both their inherent social and environmental values, just like the most traditional economic and commercial attractions.
Exchanging, reusing, second-hand markets and making good use of left-over food, for example, are actions geared towards prevention and reduction at source; a good way to make progress in minimising waste.
In the city, there are various events where people can exchange items that they no longer use but which are in a good state of repair. Other people may be able to give these items a new lease of life. This is the case with the municipal programmes "Renew your wardrobe" and "Revamp your toys", among others.
A significant part of the waste we generate can be given a new lease of life. In this area, it is worth noting the work done by the Barcelona Metropolitan Area's Environmental Body, with its "Better than new, 100% old" and "Repaired, better than new" campaigns.
Responsible consumption takes into account social, economic and environmental consequences of the product or service to be purchased. Consumers should be aware of the environmental and social impact generated by the consumption and act accordingly to try to reduce it.
