RezerolabDades: check your Catalan municipality's zero waste progress

30+ indicators for 300 municipalities, updated every year

RezerolabDades is a free public data tool built by Rezero that analyses over 30 waste-related indicators for approximately 300 Catalan municipalities each year. Indicators include separate collection rates, residual waste per capita, composting volumes, and proximity to Zero Waste targets. The tool is used by municipalities, researchers, journalists, and residents to track whether their area is moving toward or away from zero waste.

What you can do with it

• Look up your municipality's separate collection rate and compare it to Catalan neighbours
• Share results with your local council as evidence for improving collection infrastructure
• Use the data to write letters, reports, or media pieces about waste performance in your area
• Identify which municipalities are models worth visiting or learning from

How to access it

• Visit Rezero's data page for the latest RezerolabDades release
• Rezero publishes an annual summary report alongside the raw indicators

Why it matters

Accountability needs data. RezerolabDades makes it impossible for municipalities to hide poor performance behind vague statements: and equally easy to celebrate genuine progress. It is one of the most sophisticated municipal waste monitoring tools in Europe at a regional scale.
