Food & GardenCologneGet a Biotonne: close the compost loopThe simplest “zero waste” win in Cologne About 40% of what lands in the grey residual bin is compostable organic waste. In Niehl it is burned: costing money, CO₂, and fertile matter that could return to parks and gardens as torffreier Kölner Kompost. What you can do - Ask your landlord for the free brown Biotonne (tenants can use Zero Waste Köln’s postcard template on their project page). - Line the bin with newspaper, keep it in the shade, and skip “compostable” plastic bags: they need industrial conditions Cologne’s plants do not offer. - Buy Kölner Kompost or Blumenerde from AWB/AVG outlets (the Verein advocates more neighbourhood pick-up points). Why it matters Separate bio collection has been mandatory in Germany since 2015, but Cologne households still need to request the bin. Less bio in residual waste can mean a smaller (cheaper) grey bin. Source & repost Shared here so you can get inspired or find action already happening near you.

CommunityFlorenceCapannori: one of Europe's first certified Zero Waste citiesThe pioneer that showed it could be done Capannori, a municipality of about 45,000 people near Lucca in Tuscany, is one of Europe's first cities to achieve Zero Waste certification. It set out decades ago to prove that a community could dramatically reduce the waste it sends to landfill and incineration: not through technology fixes, but through source separation, reuse, and community involvement. What Capannori built - Door-to-door separate collection as the default for every household - A Zero Waste Research Centre (Centro Capannori Rifiuti Zero) studying product design flaws and advocating for producer responsibility - Composting and textile collection integrated alongside paper, glass, metal, and plastics - Waste reduction targets embedded in municipal planning Why it matters Capannori's model is not a product of wealth or special geography. It is a replicable template: start with ambitious separate collection targets, involve residents early, and redirect waste budget away from disposal toward prevention. The ZWE-certified result inspired dozens of Italian municipalities to follow. How to engage - Visit or contact Zero Waste Italy to learn how Capannori's model can be adapted for your municipality - Follow Capannori's zero waste research centre for publications and advocacy tools Source & repost Shared here so you can get inspired or find action already happening near you.

CommunityZagrebKrk Island: Europe's first certified Zero Waste island clusterSeven municipalities: one shared model Krk Island became Europe's first certified Zero Waste island when all seven of its municipalities: Krk, Baška, Dobrinj, Malinska-Dubašnica, Omišalj, Punat, and Vrbnik: achieved Zero Waste certification together through the waste company PONIKVE. The result: 60 % average separate collection and only 73 kg of residual waste per resident per year, compared to the Croatian national average of 247 kg. What makes Krk replicable - Door-to-door sorting integrated with the existing island waste system - Joint certification across multiple small municipalities sharing one operator - Farmers and hotels participate in the same collection circuits as households - Ongoing focus on waste prevention and reuse: not just better sorting How to get involved - If your municipality partners with PONIKVE, ask about volunteering in collection or composting - Visit or follow Zelena Akcija to support national Zero Waste certification advocacy Why it matters Krk shows that tourist islands: where seasonal waste peaks are hardest to manage: can still hit Zero Waste targets. The model is already inspiring other coastal communities across Croatia and beyond. Source & repost Shared here so you can get inspired or find action already happening near you.

Repair & ReuseStuttgartChoose recycled urban-mined gold for new piecesCommission jewellery from metal that already exists C. Hafner in Wimsheim near Pforzheim refines gold exclusively from secondary sources — scrap jewellery and e-waste urban mining — with published life-cycle results showing far lower CO₂ than primary mine gold. Ask jewellers for verified recycled content; route broken electronics through municipal collection so metals can re-enter refiners like this. What you can do - Ask your jeweller for 100% recycled / secondary gold before ordering a new piece - Read C. Hafner’s secondary-gold footprint note - Drop e-waste at your city’s collection point so boards can feed certified urban-mining streams How it works Refiners melt and refine post-consumer metal. Independent studies (INEC / Hochschule Pforzheim) compare secondary routes to mine gold; jewellery scrap recycling beats both e-waste and primary routes on CO₂. Why it matters Beauty that already exists can be remade — urban mining turns yesterday’s gadgets and heirlooms into tomorrow’s tools of care.

Repair & ReuseBrusselsSTICT: replicating textile waste prevention in BrusselsA city learning from the best textile programmes in Europe Brussels is participating in the STICT project (Sustainable Textile Innovation and Circular Transition), which compiles best-practice models for textile waste prevention and management and works with cities to implement and replicate them. Zero Waste Belgium leads the Brussels partnership, bringing evidence-based strategies to local authorities and businesses. What the project does - Documents the most effective textile collection, repair, and resale models from across Europe - Works with Brussels authorities to implement scalable textile waste prevention measures - Provides a replication toolkit so other cities can adopt proven approaches without starting from scratch - Connects local repair workshops, clothing swaps, and upcycling organisations into the city's circular textile network How to engage - Brussels residents: find local textile repair workshops and clothing swap events through Zero Waste Belgium - Textile businesses and retailers in Brussels: contact Zero Waste Belgium about participating in the STICT circular model - Other municipalities: request the STICT replication toolkit to adapt the Brussels approach to your context Why it matters Textiles are among the fastest-growing waste streams in Europe. Brussels joining STICT means a dense, fashion-forward city is building infrastructure for repair and reuse: sending a signal to the industry and giving residents real alternatives to disposal.

CommunityWarsawBaltic Sea coastal waste standards: building a replication model from UstkaTurning a Baltic port town's waste practices into a national template The Polish Zero Waste Association works with the gmina (municipality) of Ustka on the Baltic Sea coast, focusing on waste management standards suited to coastal environments: fishing debris, tourist-season surges, and marine plastic. The project aims to develop replicable standards for Baltic Sea coastal municipalities that other towns along the coast can adopt without having to start from scratch. What the project involves - Developing waste management standards specifically suited to coastal contexts - Collaboration with Ustka on ghost net management (see linked initiative below) - Knowledge sharing with the Pomeranian Region, which invited the Association to support circular economy models for residents - Documenting what works so that Darłowo, Kołobrzeg, Władysławowo, and other Baltic towns have a ready-made framework How to engage - Ustka and Baltic coast municipalities: contact Polish Zero Waste Association for the coastal waste standards framework - Coastal residents: support local waste sorting programmes, especially for marine debris: separate waste correctly and report illegal dump sites near the shore - Fishing communities: engage with the ghost net collection programme to ensure nets that are no longer in service enter the right waste stream Why it matters Coastal towns face waste spikes tourists never see on the map, fishing debris, ghost nets, and summer-season surges. Ustka's standards give every Baltic municipality a head start instead of reinventing the playbook port by port.
