Top ideas in Cologne
Walk Cologne with the Zero Waste Schweif
Walk Cologne with the Zero Waste Schweif Grab the Schweif booklet and one to four friends, then wander your Kiez with small tasks that help you spot waste, reuse, and resources in everyday streets. No tour guide: you set the pace. How it works - Pick up a booklet at partner cafés, unverpackt shops, or Zero Waste Köln info stands (hours vary by location). - Work through quizzes and observation prompts designed in Cologne, usable in any urban neighbourhood. - Optional deep-dive facts on the project page after you have tried the riddles yourself. Why it matters Cologne burns roughly 2,000 tonnes of waste every day; the Schweif turns that abstract number into curiosity about what we throw away and what could stay in the loop.
Swap clothes with Team Tausch in Cologne
Swap clothes with Team Tausch in Cologne Team Tausch runs small and large Kleidertausch events across Cologne. An estimated quarter of wardrobe pieces never get worn; locally, thousands of tonnes of still-wearable textiles are incinerated each year. Swapping keeps joy in fashion without the waste. What happens at a swap - Bring clean, good-condition clothes you no longer wear; take home something new-to-you. - Volunteers help with setup, guest welcome, sorting on racks, and (at larger events) a textile repair corner. - Many evenings end with music and drinks at partner venues such as the Wohngemeinschaft. Join in - Drop in as a visitor: dates are on the event calendar. - Volunteer for a 4-hour shift (no fixed commitment); cafés and community spaces can host new locations. Why it matters Swapping keeps wearable textiles out of incineration and builds neighbourhood joy around fashion without new purchases.
Bring Zero Waste into schools in Cologne
Bring Zero Waste into schools in Cologne Zero Waste Köln works in schools and out-of-school settings so young people learn separation, avoidance, and circular thinking: not guilt, but practical habits. Current offers - Bildungskoffer (in development with Universität Köln): a lending kit on waste, avoidance, and sorting for primary schools. - Schulausstellung “Zero Waste Parcours”: travelling exhibition formats (see project pages for availability). - Public talks and VHS evenings listed on the calendar. For teachers and parents Reach Team Schule/Bildung via bildung@zerowastekoeln.de for visits, materials, and volunteering (pedagogy helpful, not required). Why it matters Young people who learn separation and avoidance early carry those habits into adulthood, multiplying impact across households.
Greener carnival: sustainable Veedelszüge in Cologne
Greener carnival: sustainable Veedelszüge in Cologne The AG Nachhaltige Veedelzüge brings together BKB Verlag, Cradle to Cradle NGO Köln, Scientists for Future Köln/Bonn, and Zero Waste Köln. The aim: carnival tradition that respects materials: costumes, floats, Kamelle: without preaching from the sidelines. What the AG offers - Growing guide “Zoch ohne Driss” with tips for costumes, throws, and parade logistics. - A shared database of ideas and field reports (filter “Idee Karneval”): submit your best practice with photo rights. - Second-hand costume markets and swaps across Cologne in January/February (dates on their page). - Mini booklet giveaway “Pänz feiern Jeck - ganz ohne Dreck” for participating parades. Get involved Ideas, photos, and questions: AG-Nachhaltige-Veedelszuege@posteo.de Why it matters Karneval draws huge crowds; lighter throws and reused costumes cut parade-day waste without dampening the festivity.
Join Klima-Taler city teams across Germany in Cologne
Join Klima-Taler city teams across Germany in Cologne More than 50 municipalities use Klima-Taler. Beyond Frankfurt and Munich, residents in Cologne, Aachen, Darmstadt, Königstein im Taunus, Hamm, Kempen, Leer, and many smaller towns join a city team, race friendly CO₂ rankings, and redeem tokens with 500+ partners, including municipal pools. Tokens work across the network, not only in your home town. What you can do - Download the app from klima-taler.com and join your city's team (no name required) - Cycle, walk, or ride transit; link meters if you want energy Taler - Redeem at local partners shown in the app (pools, museums, shops, clubs) - Schools, clubs, and workplaces can start their own teams - Municipal staff: ask via the cities form if your town is not listed yet How it works Blacksquared GmbH (Berlin) runs the software. Cities pay a licence so residents and local traders join free. Treat the in-app marketplace as the current redeem list: we do not copy shop directories here. Why it matters A shared climate currency makes quiet daily trips count in public, and it keeps spend local.
Refill your bottle free at Refill Köln stations
Refill your bottle free at Refill Köln stations Refill Köln is a Zero Waste Köln project turning willing shops, cafés, cultural venues, and restaurants across Cologne into free drinking-water stops for anyone with an empty bottle. What you can do - Look for the round blue "Refill Station" sticker in a window, then ask to fill your bottle with tap water: free in shops, restaurants may add a small service charge - Respect that every station joins voluntarily and unpaid, so a full till, a grubby bottle, or a big canister can mean a polite no - Ask your favourite café, shop, or workplace to become a station by emailing refill@zerowastekoeln.de: all it needs is regular opening hours and a way to fill bottles How it works Refill Köln plugs into the nationwide Refill Deutschland network under the Zero Waste Germany umbrella, so the blue sticker means the same thing wherever you spot it across the country. Why it matters Cologne's tap water is closely tested and costs well under a cent a litre, yet plastic bottles still pile up citywide. Choosing a refill over a new bottle is a small swap that could spare Germany billions of plastic bottles a year if the habit catches on.
Rescue deposit glass at street festivals in Cologne
Rescue deposit glass at street festivals in Cologne At parades and mega-events, returnable glass often misses the deposit system. Zero Waste Köln volunteers collect bottles so they reach supermarkets and breweries instead of residual waste or incineration. What you can do - Join parade and festival glass collections, email aktionen@zerowastekoeln.de - Bring gloves and sturdy bags; many collectors focus on plastic, glass needs extra hands Recent impact (from their project stories) - Sülzer Veedelszug 2025: 600 bottles with KG Grüne Rheinfunken (logistics: Gaffel). - Cologne Pride 2025: 6,500 bottles with Rheinfunken, Cradle2Cradle, Zukunft feiern, Grüngürtelrosen, Veedelperlen. - gamescom festival: 120 beer crates of empties with Feiermacher. Why it matters Every bottle returned to Pfand keeps glass in the brewery loop instead of residual waste or street litter after mega-events.Initiatives in Cologne
