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.

Plant seagrass meadows with Posidonia volunteers

Help Mediterranean seagrass meadows recover Posidonia oceanica meadows shelter fish nurseries, calm waves, and store carbon along Spanish and Italian coasts. Volunteer planting and monitoring programmes invite residents to restore underwater meadows bay by bay. What you can do - Join GreenLife4Seas citizen science and restoration calls along the Catalan and Apulian coasts - Learn safe planting techniques with local diving clubs and marine biologists - Map meadow edges and report anchor damage to harbour managers How it works Teams coordinate seasonal planting windows when water is clear. Volunteers with snorkel or dive certification plant shoots in marked plots and return to photograph recovery. Why it matters Seagrass meadows are living breakwaters: they protect beaches, feed fisheries, and keep water clear for everyone who swims nearby.

What you can do - Browse MedPAN member reserves near you and ask about volunteer roles - Lead snorkel briefings that teach respectful wildlife watching - Help translate visitor guides so local fishers and tourists share the same rules How it works Reserves train stewards on seasonal tasks: nesting season rope lines, invasive species pulls, and underwater photo transects. Why it matters Protected coves recover fast when residents feel ownership: compliance rises and fish spill over into neighbouring waters.

Spain: Barcelona Energy Advice Points

One-stop shops for efficiency and energy poverty relief Since 2017, Barcelona has run 11 Energy Advice Points integrated into municipal housing offices.

Barcelona school food surplus: recovering canteen leftovers for the community

Less food waste: more community benefit from school kitchens Rezero, working with the Barcelona City Council and the La Noguera City Council, developed a programme that channels surplus food from school canteens to community benefit rather than the bin.

Viladecans Plastic Prevention Plan: binding measures already running

A ZW candidate city taking plastic seriously Viladecans, a municipality of 70,000 on the southern edge of Barcelona, is a Zero Waste candidate city and a participant in the EU ERIC (Elevating Reuse In Cities) project alongside Torrelles de Llobregat. In 2024, Viladecans became one of the first Catalan cities to approve and begin implementing a binding Plastic Prevention Plan: a document that commits the municipality to specific, measurable plastic reduction measures already underway. What the plan includes - Reduction of single-use plastics in municipal events and public spaces - Promotion of reusable alternatives for takeaway containers in local hospitality - Procurement criteria requiring plastic-free options for city contracts - Monitoring and annual public reporting on plastic reduction outcomes How to participate - Attend Viladecans municipal events: they are piloting reusable tableware and cup systems - Ask local restaurants and bars about takeaway reuse options promoted under the plan - Follow Rezero for the ERIC project updates on reuse infrastructure in Viladecans Why it matters Binding plans with implementation already started are rare: most cities stop at commitments. Viladecans's plan, combined with its ERIC project participation, makes it one of the most concretely active zero waste cities in Spain right now.

Torrelles de Llobregat: certified and plastic-free by plan

A certified Zero Waste city with a binding plastic prevention plan Torrelles de Llobregat, a small ZWE-certified Zero Waste municipality in Catalonia, took its commitments further in 2024 by approving and starting to implement a binding Plastic Prevention Plan: following the same model as candidate city Viladecans. Torrelles also participates in the ERIC project alongside Viladecans, creating a productive pair of municipalities that share tools, funding, and lessons. What Torrelles shows - Small certified municipalities can lead on plastic prevention without large budgets - Certification and plastic prevention planning are complementary: not sequential - The ERIC project provided both the methodology and funding that made the plan viable What you can do - Visit Torrelles as a case study if you are working on Zero Waste strategies in your own municipality - Contact Rezero to access the Torrelles and Viladecans plastic prevention planning tools - Follow the ERIC project for replicable reuse infrastructure models applicable to any small city Why it matters Certified cities that continue innovating: instead of resting on certification: keep the Zero Waste movement credible and dynamic. Torrelles's plan shows that even very small municipalities can set binding plastic reduction targets.
