Join NABU SiWi nature nights in Siegen

Join NABU SiWi nature nights in Siegen NABU Kreisverband Siegen-Wittgenstein keeps an open monthly nature night at the Heimathaus in Siegen-Bürbach. Fourth Wednesday, 19:00. In summer the same circle often swaps the room for a nature walk in and around Siegen. There is no separate named Sieg-river work day on the mitmachen page. What you can do - Come to a fourth-Wednesday night via NABU SiWi Mitmachen - Ask about the next outdoor excursion if you prefer boots to chairs - Call 02753 599001 or email if the meeting point has shifted How it works Indoor nature nights are the regular door. Summer walks replace some evenings. Solarpunker does not keep the key to the Heimathaus. Why it matters A monthly table in Bürbach is an easy way to meet people who already know Siegerland heath, owls, and weekend habitats.

Join a NABU SiWi summer nature walk

Join a NABU SiWi summer nature walk In summer the fourth-Wednesday circle often leaves the Heimathaus for a nature walk in and around Siegen. Same friendly group, outdoor meeting point. What you can do - Ask on Mitmachen or by phone whether the next fourth Wednesday is a walk - Wear outdoor shoes; the exact trail is announced with the date - First-timers are welcome; this is not a closed members hike How it works Seasonal outdoor swap, not a separate named river work day. Confirm the meeting point. When & where Seasonal summer pattern on or around the fourth Wednesday. Default pin remains the Heimathaus (Obere Dorfstraße 32, 57074 Siegen-Bürbach): 50.8755, 8.0475, unless the organiser names another trailhead. Why it matters A dusk walk is how indoor nature nights grow roots in actual Siegerland habitat. Source & repost Shared here so you can get inspired or find action already happening near you.

Get a Biotonne: close the compost loop in Cologne

Get a Biotonne: close the compost loop 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.

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.

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.
