CommunityHamburgBuild a Fab City local node and open learning dayPrototype solutions your city can actually produce Fab City invites territories to commit to making more of what they consume. The How to Become a Fab City guide walks groups through stakeholder maps, pilot projects, and open learning days that welcome first-time makers. What you can do - Read the Fab City Hubs Toolkit with a small founding team - Host a monthly open lab afternoon: one taught skill, one shared tool, one neighbourhood challenge - Submit your hub story to the Fab City Learning Hub resource library How it works A local node partners with schools, libraries, or cooperatives for space and outreach. Pilots test circular products (repair, textiles, food processing) before scaling. The global network reviews and spreads what works. Why it matters Cities that learn to make together depend less on fragile supply chains. Open learning days lower the threshold for anyone curious about fabrication.

Repair & ReuseHamburgReturn scrap jewellery to a ScheideanstaltKeep old gold in the loop instead of a drawer Norddeutsche Edelmetall Scheideanstalt in Norderstedt (with Hamburg and Buxtehude desks) buys and refines scrap jewellery, dental gold, and silverware. Consumers book a drop-off; the plant recovers gold, silver, platinum, and palladium for new craft and industry — classic urban mining without a landfill detour. What you can do - Book a drop-off via Terminbuchung (appointment required) - Bring old jewellery or dental scrap; read Goldschmuck Ankauf first - Ask whether you want cash or refined metal returned for a remake with a local goldsmith How it works The Scheideanstalt assays and separates metals in closed processes using secondary feedstock only. Recycled fine metal re-enters jewellery and industry supply. Why it matters Every gram recovered at home is a gram that need not leave a new scar on a distant hillside.

Food & GardenHamburgCo-found a community-supported agriculture (CSA) farm shareStart a Solawi collective with neighbours The Solawi start guide walks groups through finding land, drafting a fair contract, and recruiting founding members before the first sowing season. What you can do - Read the gründen (start) resources and download the checklist for your region - Host an info evening in Hamburg with farmers, lawyers, and future members in the same room - Pair with an existing farm willing to transition from wholesale to community shares How it works Founders agree on pricing, labour expectations, and what happens in a bad harvest year. The network offers peer calls so new groups learn from farms that already run on solidarity principles. Why it matters Starting a Solawi creates permanent local food infrastructure, not a one-off box scheme. Source & repost Shared here so you can get inspired or find action already happening near you.

CommunityHamburgSecure collective housing with Mietshäuser SyndikatBuy the building together and keep it off the market The Mietshäuser Syndikat helps self-organised house projects in Germany: residents form a cooperative, the syndicate takes a stake, and the building stays permanently out of speculative resale. What you can do - Read how the Syndikat model withdraws homes from the private market - Contact the network if your group is forming a self-organised house project - Visit an existing project to see how residents share costs, repairs, and decision-making How it works A founding group finds a building, sets up a limited-liability housing cooperative, and invites the syndicate to co-own a non-voting share. That lock keeps the property community-held even when individual flats change hands. Why it matters Collective ownership turns rent pressure into shared stewardship. Neighbours who control their block can invest in efficiency, childcare, and common rooms together. Source & repost Shared here so you can get inspired or find action already happening near you.

CommunityHamburgPatient capital for African social startupsReinvest returns instead of one-off aid projects Impacc is a non-profit based in Germany, Kenya, and Ethiopia that uses business tools for social change. Instead of funding aid projects that end when the money runs out, Impacc invests donations in locally rooted, ecologically sustainable businesses, then reinvests any exit returns into the next cohort of founders. What you can do - Study Impacc's Cycle of Growth: due diligence on outstanding (often female) founders, patient capital to de-risk growth, and board support that helps companies attract follow-on investment - Adapt the model for your city: a revolving community fund that backs neighbourhood enterprises rather than one-off grants - Share the gap narrative with local policymakers: entrepreneurs who are too business-like for traditional aid but not yet bankable for commercial investors How it works (paraphrased) 1. Enable founders, select innovative models with job-creation potential in underserved markets 2. De-risk capitalization, scale proven ideas with venture building and patient capital 3. Perpetuate growth, minority stakes, board seats, and reinvestment of exits into new rounds (Impacc does not keep profits) Why it matters Development engines should keep running. A non-profit that treats social startups like long-term community assets gives builders a bridge between charity and venture capital.
