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.

RewildingStuttgartSit in a Mobiles Grünes ZimmerRest in a rolling green room on the plaza Helix's Mobiles Grünes Zimmer is a freestanding green wall and kiwi trellis on a roll-off container: shade, edible herbs, seating, and a climate-adaptation demo that cities, schools, and citizen groups can host. Since 2016 the rooms tour public squares, stations, and events across Germany. What you can do - Sit and cool off when a room is deployed near you (Stuttgart-Feuerbach station plaza has hosted one) - Ask your school, Ortsbeirat, or Bürgerinitiative to host a room for a festival, heat day, or neighbourhood pop-up - Use the side panels as a meeting point for climate and greening talks How it works A truck drops the pre-grown room; Helix handles most care. Local organisers top up the water tank. Residents get an instant cool oasis without digging the square. Why it matters Heat islands become places to linger. Neighbours feel what green infrastructure can do before permanent plantings arrive. Source & repost Shared here so you can get inspired or find action already happening near you.

RewildingStuttgartPark a Klimakiste for bees and neighboursRoll native planters onto a paved square The Helix Klimakiste is a pre-grown wooden box (about 120 × 100 × 80 cm) with a solitary shrub and flowering underplanting. Citizen initiatives, schools, and cities can move boxes in for events or trials, then move them again. Plant for wild bees from day one. What you can do - Propose Klimakisten for a schoolyard, market, or temporary greening ask via Helix Klimakiste - Help water and tend boxes when your group hosts them - Choose native perennials so insects find food on sealed ground How it works Boxes arrive cultivated and move with a pallet jack. They buy time: prove that plants change how a place feels before you unseal asphalt for good. Why it matters Paved plazas can still feed bees and invite conversation. Temporary green is a rehearsal for lasting canopy. Source & repost Shared here so you can get inspired or find action already happening near you. Solarpunker does not own or organise it.

CommunityStuttgartTrial traffic calming with mobile greenTest a greener curb before permanent rebuild Mobiles Grün lets neighbourhoods try converting a parking or traffic strip into stay-space with planters and seating. After a successful trial, cities can lock in lasting greening. Fast, reversible, and cheaper than guessing. What you can do - Ask your Ortsbeirat or district office for a timed parking-bay greening pilot - Partner with schools or Bürgerinitiativen to staff watering and weekend presence - Document who uses the space, then push for permanent unsealing if it works How it works Mobile containers and parklet-style kits occupy curb space for a set period. Neighbours live with the change, then decide together whether to keep it. Why it matters Streets learn in public. A temporary green bay is how communities prove cooler, quieter blocks without waiting for a full rebuild.

RewildingStuttgartGreen shade routes & unsealing for urban coolingMore green, less grey, cooler streets by design Heat and sealed surfaces go together: asphalt stores warmth, while trees and unsealed soil cool the block. Cities are extending Schattenwege (shade routes), depaving yards, and co-designing green corners with residents. What you can do - Walk a municipal Schattenweg route and suggest the next link (Esslingen extends its shade path each summer) - Join participation formats for new neighbourhood green (for example FairFuture co-design in Hamburg-Veddel) - Support local Flächenentsiegelung projects that swap paving for planting (Recklinghausen Hitzeschutzbündnis model) Why it matters Every square metre unsealed is a small air conditioner the whole Kiez shares, biodiversity and comfort in one intervention.
