Barcelona's Hidden Recyclers: How Informal Waste Pickers Keep the City Clean

Informal waste pickers (IWPs) are a big part of how cities handle trash, yet their work is often overlooked. While this practice has long been studied in developing nations, it is only recently gaining attention in places like Barcelona, Spain. Researchers decided to take a close look at how these workers fit into the city's recycling system. They gathered information through on-the-ground observations, surveys, talks with community members, and data from other sources. The numbers they uncovered were striking. Between 1,640 and 1,940 people work as informal waste pickers in Barcelona, putting in nearly 60 hours each week for roughly €2 per hour — far below the country's minimum wage. These workers handle a massive share of the city's meta

l waste, collecting between 33% and 39% of it. Their efforts also prevent the release of at least 36,000 to 41,000 tonnes of CO2 every year and save between 42,000 and 69,000 cubic metres of water annually. Despite this enormous contribution, the workers face very harsh conditions. They are essentially providing free or very cheap labour to the recycling industry while the financial benefits stay with private companies and public authorities. The study argues that cities like Barcelona need to recognize and support these workers through new policies that guarantee fair treatment, better pay, and genuine inclusion in urban planning. Without such changes, the current system keeps exploiting a workforce that keeps the city's environment clean.
