The development of the concept of prevention includes the zero waste strategy and the circular economy. It is based on the reduction of waste products, reuse (exchange + repair of appliances), recycling and co-responsibility.
Barcelona City Council is promoting the prevention of waste in different fractions, including: organic matter, lightweight packaging, paper-cardboard, glass, bulky waste and waste electrical and electronic equipment (WEEE).
In 2011, with the aim of including prevention in Barcelona's waste-management model, in line with the most recent European strategies, Barcelona City Council developed its 2012-2020 Waste Management Plan.
The general public's co-responsibility in waste prevention is all about small actions that can be incorporated into people's daily lives.
