Hofflohmärkte, neighbourhood courtyard flea markets

Browse linked tour plans through your Viertel Hofflohmärkte is a Germany-wide reuse programme: residents register a private courtyard, garden, or garage and sell pre-loved goods while neighbours follow a linked tour plan through the district. The platform runs in 30+ cities and 300+ neighbourhoods; initiator René Götz operates registration, participants organise their own courtyards. What you can do - Download the tour plan PDF for your Viertel (published about one week before each market day) - Walk the linked addresses and buy second-hand treasures from neighbours - Register your own Hof if you have landlord approval and goods to pass on How it works - Sales stay on private ground only, not sidewalks or public space - Typical hours: Saturdays 10–16, Sundays 11–16 (Munich also runs selected Friday evenings with M-net sponsorship) - No food sales; private sellers only, professional dealers are not welcome - Registration closes three weeks before each date for tour-plan marking; late sign-ups are accepted but may not appear on the map - Organisers may cancel a date if fewer than 30 courtyards register, fees are then refunded About Hofflohmärkte Neighbours register a private Hof, Garten, or Garage on Hofflohmärkte and sell used goods on scheduled Viertel days. Registered addresses appear on a tour plan published about one week before each date. Sales happen on private ground only. See city pages for local schedules and Spielregeln & Tipps for seller rules. Why it matters Every item re-homed from a courtyard is one less thing bought new or landfilled, and a chance to meet the people who live behind the front doors.

Support recycler cooperatives managing organics in Buenos Aires

Segregation at source: cooperatives in charge Argentina’s FACCyR-linked recycler groups manage organic streams where source segregation is in place, a pattern the 2025 regional report pairs with Colombian ANR experiences. Cooperatives such as El Amanecer de los Cartoneros in Villa Fiorito show how sorted organics and recyclables can stay in community hands. What you can do - Sort organics and clean recyclables before cooperative pick-up on your block. - Connect your barrio association with a registered cartonero/a cooperative for collection routes. Why it matters Recycler-led organics management turns a climate liability into local jobs and compost, without shipping waste out of sight.

Bled STICT: circular textile challenge with international experts

Tackling tourism's textile footprint Under the EU STICT (Sustainable Textiles In Circular Tourism) project, EBM partnered with the municipality of Bled and international sustainability experts to explore solutions for the environmental and economic impacts of textiles in a tourism-heavy destination. The initiative investigates sustainable sourcing, collection, and reuse of textiles across hotels, venues, and local businesses in the Bled area. What the project explores - Environmental footprint of hotel linen and event textiles - Collection and redistribution systems for reusable or recyclable textiles - Policy levers municipalities can use to shift procurement How to engage - Follow EBM for workshops and findings as the STICT project publishes results - If you manage a venue near Bled, ask EBM about participation in the textile audit pilot Why it matters Tourism destinations generate disproportionate textile waste. Bled's participation in STICT means findings apply directly to one of Slovenia's most visited areas: making lessons replicable for every European resort town.

Zagreb Plastic Prevention Plan: ban single-use, refill the city

From city buildings to hospitality venues Zagreb adopted a Plastic Prevention Plan as part of the ERIC project: one of the most comprehensive municipal plastic policies in the Western Balkans region. The plan bans single-use plastics across all city-owned buildings and institutions and combines that with public infrastructure to make reuse the easy default. Measures already running - New and repaired public drinking-water fountains installed across the city to cut single-use plastic bottle purchases - Single-use plastic items removed from select city-organised events - Support for hospitality businesses switching to reusable packaging What you can do - Use the public refill fountains instead of buying bottled water - Ask event organisers in Zagreb whether the venue is single-use-plastic-free - Talk to your neighbourhood association about advocating for more refill points in your district Why it matters Policy without infrastructure fails. Zagreb pairs the ban with visible reuse alternatives: showing that a city of almost one million can shift habits at scale.

Repair & ReuseSilves

Silves: Portugal's first separate stream for sanitary textiles and diapers

A collection pilot the rest of Portugal is watching Silves, an Algarve municipality, became the first in Portugal to collect sanitary textiles and diapers as a dedicated separate waste stream: a hygiene category that normally ends up in residual waste and goes straight to landfill or incineration. The pilot, supported by ZERO, forms part of Silves's broader door-to-door collection overhaul in the Algarve region. Why it matters Diapers and sanitary textiles make up a significant share of household residual waste, yet they usually ride straight to landfill in mixed bins. Silves is Portugal's first dedicated collection pilot, a reference case other municipalities can copy once results are in. What you can do - If you live in Silves, ask the municipal environment office how to access the dedicated collection point or service - Advocate for this stream in your own municipality by sharing Silves's results with local councillors - Follow ZERO for policy developments around this waste stream nationally Source & repost Shared here so you can get inspired or find action already happening near you.

Return scrap jewellery to a Scheideanstalt

Keep 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.

Choose recycled urban-mined gold for new pieces

Commission 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.
