Currently, nearly a third (31.7%) of the waste generated ends up in one of the 25 landfills available in the country. However, according to the targets set by the European Union, these controlled landfills should only be the final destination for a maximum of 10% of municipal waste. Although government sources have positive assessments of waste collection and treatment in recent years, the data show that Catalonia is still far from meeting European targets. Given this scenario, one of the measures the government is proposing to close the gap involves closing half of its landfills.
