Join Foodtura City Experiences in Frankfurt
Join Foodtura City Experiences in Frankfurt Foodtura is a ten-day festival (18 to 27 September 2026) where restaurants, farms, initiatives, and kitchens open their doors. Klimagourmet and Initiative Gastronomie Frankfurt organise about 50 City Experiences: tastings, workshops, bike tours, playground markets, and neighbourhood tables. Many events are free. Massif Central on Bethmannstraße is the festival hub. What you can do - Browse the live programme and book the events that fit your week - Start at the free Opening (18 September) or the Playground market (19 September) - Bring neighbours to a supper club, farm day, or unpackaged shop action listed on the map - Follow Über Foodtura for who is behind the festival (not a Solarpunker event) How it works Hosts publish dates, prices, and booking links on each event page. Tickets, if any, go to the organiser. Solarpunker does not take bookings. The programme can still grow through September, so check the festival site before you travel. Why it matters Sustainable eating is easier when it is delicious, local, and shared. Foodtura turns that into a week of doors you can actually walk through.
Visit Rhine-Main organic farms this harvest wee in Frankfurt
Visit Rhine-Main organic farms this harvest wee in Frankfurt Dottenfelderhof in Bad Vilbel, Querbeet's Pappelhof in Reichelsheim, and Die Kooperative's Cityfarm in Oberrad open for Foodtura: apple pressing, potato digging, a hen walk, a farm festival, and a free family Sunday with a Schnippelparty in Frankfurt. What you can do - Press juice at the Jahreszeitenwerkstatt (19 September) - Dig your own potatoes at Pappelhof - Meet the hens or join the free Hoffest at Dottenfelderhof - Close the festival at the Familiensonntag on the Cityfarm (free) - Book the Farm to Table dinner at Tonka if you want a long table of Cityfarm vegetables How it works Farm days list prices and booking links on each page. The Hoffest and Familiensonntag are free drop-in. Wear shoes you can get dirty. Why it matters Seeing soil, animals, and harvest in the same week as city kitchens makes regional food feel real.
Join invasive-species talkoot in Helsinki
Join invasive-species talkoot in Helsinki Helsinki supports talkoot against invasive plants in city green areas. Sign up through the volunteer portal and join a work day. What you can do - Open the invasive species volunteer page - Pick a listed talkoot date - Wear gloves and sturdy shoes How it works City-supported work days. Meeting points vary by green area; follow each listing. Why it matters Helsinki neighbours defend local plants with shared hands, not only bylaws.
Loan heirloom seeds like a neighbourhood library
Loan heirloom seeds like a neighbourhood library In Yaxunah, Yucatán, nine women run K'an-Lol ("the flower of good corn" in Yucatec Maya): a community seed bank that loans traditional maize, beans, chilies, and other crops at no cost. Borrowers plant their milpa, harvest, and return fresh seed so the stock stays alive for the next season. Most users are subsistence farmers feeding their families, with small surpluses sometimes reaching local markets. The bank is a library, not a shop: seeds move in circulation instead of sitting in a vault. Fundación Haciendas del Mundo Maya supports the project alongside local volunteers. Surplus garden produce can reach buyers through Traspatio Maya (Instagram). What you can do - Visit Yaxunah when community programmes are open and ask how the seed bank lends and receives maize (see Yucatán Magazine coverage) - Message Traspatio Maya to order a guacal of fresh produce from Yaxunah growers when you are in the region - Replicate the pattern at home: labelled jars, a simple loan ledger, and a rule to return double the borrowed grain if you cannot swap seed immediately (as Yaxcabá neighbours describe for their bank) - Pair seed saving with nixtamalization skills so heirloom maize becomes tortillas and staples again, not just decoration How it works Farmers borrow seed, grow in milpa plots, and return after harvest. Varieties such as nuuk nal (reddish maize) stay in use even though they need more care than industrial hybrids. Coordinators track loans; partners like FHMM help with training and fair-trade outlets. There is no fixed online booking: contact organisers through community channels or partner foundations before you travel. Why it matters Imported kernels can cross-pollinate native fields. A seed library keeps criollo genetics in farmers' hands, not only in policy speeches. It is low-tech mutual aid that scales one neighbourhood at a time.
Walk historic energy and transport networks
Walk historic energy and transport networks The 2026 motto NetzWERKE: Denkmale & Infrastruktur puts bridges, locks, power houses, rail sheds, and supply buildings in the spotlight. These places once moved people, water, goods, and power. On Open Monument Day they open so you can see how earlier networks still shape streets and rivers. What you can do - Search the programme for industry, Technik, or infrastructure tags near you - Visit a dated listing such as Dresden's Bahnbetriebswerk Dresden-Altstadt when it opens - Ask guides how the site fed a town: water, power, freight, or passenger rail - Carry the pattern into advocacy: keep repairable infrastructure visible in your own city How it works DSD invites owners to present monuments as network nodes, not only as pretty facades. Filter for technical monuments, then pick one deep listing with hours and access notes. Why it matters Energy and transport heritage make climate and mobility conversations tangible. You stand inside the systems that still underwrite daily life.

Visit circular demolition salvage at Prinsenhil
Visit circular demolition salvage at Prinsenhil You can trace circular demolition at Prinsenhil in Breda, where a large hall was taken apart for reuse. Look along the Prinsenhil road. The place is the district, not a gate you should enter. What you can do in Prinsenhil - Read the February 2023 account before you go (WDP story) - Look from public roads only. Do not enter a works compound - If you renovate, ask whether beams, roof panels, clinker, or steel from this kind of job are still for sale - Ask a local builder to keep the next concrete floor on site as a base or a site road How to join WDP and Gubbels ran this as a build project. In the February 2023 note the first phase was about 90 percent done, and a second taking-apart was planned for early 2024. Those dates are a record of the method, not an invitation to a live tour. Salvage was sold mainly to private renovators. Regular buyers saw the measured, photographed list first. When & where Prinsenhil, Breda, the Netherlands. The place is the Prinsenhil road in the Krogten area. There is no public counter with a street number. Recurring: there is no weekly open hour. Check the WDP page for any current note. Why it matters in Prinsenhil The concrete slab was reused on the site as a foundation and as a construction road. Cooling walls went to a cold-store dealer. Long steel went into new frames. Stone was planned for green walls along walking and training paths. That is the picture to copy on the next large hall in Breda. Good to know - Is the site open to visitors? No public open day is described. Stay on public ground. - Who sells the parts? The demolition team. WDP said it barely handled resale. Check the WDP page for any current list.

Walk Musicon after circular demolition there Musicon in Roskilde is the district where circular demolition of factory Hall 12 was planned with a full material audit. You can walk the old concrete-works ground and see a neighbourhood built from that site. What you can do in Musicon - Walk the public streets and yards of Musicon (CityLoops circular demolition) - Notice which old sheds and open ground remain beside newer buildings - Ask Roskilde to attach a pre-demolition audit to the next demolition tender - If you pay for a job, copy the Værdibyg steps: survey, set a reuse aim, then tender How to join The Hall 12 audit was done by Golder for the city: desk study, field study, and a plan for each pile, plus a store of saved parts. That work is finished. The district is still there to visit. There is no ticket and no volunteer shift for the old demolition. Come as a walker. When & where Musicon, Roskilde, Denmark. Go to the district, not to a marked door for Hall 12. The city bought the 200,000 square metre concrete factory and gravel pit in 2003. Recurring: the streets are public. Check the city pages if you want a guided note. Why it matters in Musicon The audit happened early so designers and the demolition contract could use the same list. CityLoops says that once a contractor is hired, they will not add this screening unless the tender already required it. Walking the district shows why that timing matters: the old works are becoming streets, homes, and culture space. Good to know - Can I see Hall 12 itself? Hall 12 was partly taken down after a material list. It is not a museum room. Visit the district. - What should a tender say? Require the audit and the selective take-down before the contract is signed. Source & repost Shared here so you can get inspired or find action already happening near you.

See the kept hall: circular demolition Taastrup The old Høje-Taastrup city hall at Bygaden 2 is the place where circular demolition rules changed the plan from a full knock-down to keeping the building. You can see it from the street. What you can do in Taastrup - Walk to Bygaden 2 and look at the 1980 hall from public ground (municipal note) - Compare it with the new hall at Rådhusstræde 1, built with a recycled concrete foundation - Ask a council you vote in to sell its next empty building with a reuse rule, not a default demolition - Read the CityLoops lesson: name the need (homes, workplaces) before you name a demolition How to join There is no public tour in the source. The building stood empty after February 2023, when staff moved to the new hall. IKANO is turning the old hall into homes and adding townhouses on the grounds. A small neighbourhood house is planned in the former heat plant. Stay outside unless the owner publishes a visit. When & where Bygaden 2, 2630 Taastrup, Denmark, by Høje Taastrup village. The new hall is a different building at Rådhusstræde 1. Recurring: the old hall remains a street address you can look at. Works may change access, so check the municipal page. Why it matters in Taastrup The CityLoops account says keeping this hall saves about 20,000 tonnes of raw material and about 2,000 tonnes of carbon dioxide versus demolition. The sale still carried a rule: if parts must come off, at least 80 percent by weight of the clean material should be reused, recycled, or recovered. A structure that stays up counts as kept. Good to know - Is the hall still there? Yes. The later municipal note says it will be transformed, not razed. About 200 homes are planned in the hall, plus about 130 townhouses. - Can I go inside?

Ask Mustang for circular demolition in Berkel Mustang Demolition keeps a yard for circular demolition parts at Noordeindseweg 346A in Berkel en Rodenrijs. Glass and steel from greenhouses come here to be checked, cleaned, and sent out for another build. What you can do in Berkel - Contact Mustang before a greenhouse is cut down (circular demolition page) - Ask for an inventory that names what can be used again and what it is worth - Ask which parts will be stored at this yard and which will be rebuilt for a customer - Ask how parts that cannot be reused will be taken away How to join You ask the firm. They map the materials, take the reusable ones off, and bring them to this address. On arrival the parts are checked, cleaned if needed, registered, and stored. The page says most of them go into new greenhouses. It does not publish walk-in hours. Use the contact page and ask before you travel. When & where Noordeindseweg 346A, 2651 LM Berkel en Rodenrijs, the Netherlands. Recurring: the yard is the firm base. Check the organiser page for whether visitors are welcome. Why it matters in Berkel A greenhouse frame is a kit of glass, gutters, and steel. Taking it apart with a list means the next grower can build with parts that already exist. The yard is the place those parts wait between the old site and the new one. Good to know - Is this a public shop? The page describes a yard and a contact path, not a counter with opening hours. Ask first. - What about cost? The page does not list a fee. Ask Mustang. Source & repost Shared here so you can get inspired or find action already happening near you.

Reuse pavers: circular demolition Apeldoorn Griffiersveld in Apeldoorn is the residential street where circular demolition put the old concrete pavers back to work. More than 4,600 square metres were lifted and reused on the street and on nearby farms. What you can do on Griffiersveld - Walk the street and look at the pavers under your feet (CityLoops handbook) - Ask the municipality to measure the next road before it is broken up - Ask them to list spare pavers on DuSpot, the matching tool they chose - If you need hard paving nearby, ask whether a city depot still holds stones from a job like this How to join The renovation itself is complete. You join by walking the street and by asking the city to repeat the rule. Materials from Apeldoorn projects, and stock in municipal depots, were to be listed on DuSpot after the agreement. There is no ticket and no meeting time. When & where Griffiersveld, Matenveld, Apeldoorn, the Netherlands, postcode area 7327 DV. Recurring: it is a public residential street. Be a quiet guest of the people who live there. Why it matters on Griffiersveld Road jobs throw away huge areas of sound pavers. Here the stones stayed in the neighbourhood. The count before the works told the city how much it had and how good it was. That list is what makes the next match possible. Good to know - Is there a visitor centre? No. The street is the evidence. - What else was in the mix? Concrete, bricks, tiles, ceramics, stone, and soil.

Trace circular demolition sites in Mikkeli Kiiskinmäenkatu is where the Pankalampi health centre stood until a circular demolition in 2021. Tuukkala hospital, the second site, was taken down the same year. Both are patterns you can ask the city to repeat. What you can do in Mikkeli - Stand on Kiiskinmäenkatu and see the former health-centre block (Mikkeli) - Ask Building Services to attach the CityLoops sorting rules to the next contract - Ask crews to clear doors, furniture, and easy parts before the heavy demolition, so those parts can be sold - Visit Mikkelipuisto for granite that left the Tuukkala yard for the park How to join You are visiting former sites, not a live crew. Pankalampi was about 9,855 square metres: health centre, dental clinic, and a garage. The city recovered a fire escape for a day care and sold the backup power plant. A few windows went to two people. Tuukkala had been empty since 2010, so almost no furniture could be saved. Oak boards from balconies and the doorway became a table top and cutting boards at ESEDU. When & where Kiiskinmäenkatu, 50130 Mikkeli, Finland. Stand on the street. The buildings are gone. The health centre stood on this street. Tuukkala was a second site in the Tuukkala district, vacant for more than ten years before the 2021 works. Recurring: there is no open hour. The streets are public. Why it matters in Mikkeli More than 99 percent of the demolition material was sorted into separate piles. At Tuukkala that was 9,019 tonnes, with more than 8,000 tonnes of concrete and brick. The lesson to copy is the contract line: name the piles, name who strips the building, and check the piles while the work is going. Good to know - Who did the work? Ahosen Palvelut of Jyväskylä at Pankalampi. Terra Infra of Kouvola at Tuukkala. Metsäsairila took the sorted loads. - Can I collect leftover bricks? The 2021 sales are over. Ask the city about the next contract. Source & repost Shared here so you can get inspired or find action already happening near you. Solarpunker does not own or organise it.
