Exit the Supermarket: “Naked Corners” Arrive in Other Retail Chains in Rennes

The announcement from Le Super tout nu in Rennes about closing its standalone storefront after just five months might seem like a distant French retail story, but it carries a stark warning for zero-waste initiatives taking root in American cities like Portland, Oregon. When a dedicated zero-waste supermarket shuttering its doors in Rennes cites challenges sustaining the model, it prompts a necessary conversation here in the Pacific Northwest about the viability and evolution of similar concepts we’ve embraced, from the refill stations at New Seasons Market to the package-free aisles popping up in independent grocers across Southeast Portland and along Alberta Street.

The Rennes situation, as reported by local French outlets including actu.fr and Ouest-France, wasn’t a gradual fade but a decisive pivot announced via Facebook on April 21st, with closure set for May 9th, 2026. Opening only in December 2025 at 5 rue de la Chaussée, the Toulouse-born Super tout nu chain found the standalone, full-format zero-waste supermarket model difficult to maintain, despite offering 3,000 references and the core appeal of products in consigned glass jars and cloth bags. Their explanation points to a strategic recentering: exiting the traditional supermarket format to focus exclusively on establishing “corners tout nus” – dedicated zero-waste sections within existing larger grocery chains. Notably, they confirmed their products are already available in Rennes at Intermarché locations on avenue Jean-Janvier and aux Gayeulles, with a potential new corner reportedly planned for Pacé to the northwest. This isn’t abandonment of the zero-waste mission but a stark acknowledgment of the economic pressures facing pure-play specialists, leading to a 50% storewide liquidation sale as they wind down operations.

Translating this macro trend to the micro reality of Portland reveals fascinating parallels and divergences. Our city, a longstanding hub for sustainability innovation, hosts numerous zero-waste advocates and businesses, from the pioneering efforts at stores like People’s Food Co-op to newer refill concepts. Yet, the Rennes experience echoes concerns voiced locally about the scalability of the model. Operating a zero-waste business involves significant complexities: sourcing bulk products with verifiable sustainable supply chains, managing the logistics and hygiene of consigned container systems (which require robust washing and tracking infrastructure), and often contending with higher price points that can limit accessibility, especially when compared to the convenience and pricing power of conventional supermarkets. The Rennes shift towards integrating zero-waste offerings into established retailers like Intermarché mirrors a strategy already seen here, where larger chains such as Market of Choice or even select Safeway locations have begun trialing dedicated refill stations for grains, spices, and cleaning supplies. This hybrid approach leverages the foot traffic and operational scale of big grocers while attempting to offer the package-free option, potentially solving the customer acquisition challenge that likely contributed to Super tout nu’s Rennes struggle.

However, this transition isn’t without its own set of local considerations unique to Portland’s landscape. The city’s strong independent business ethos, fostered by organizations like Portland Means Progress and supported by policies from the Bureau of Planning and Sustainability (BPS), means there’s significant value placed on maintaining diverse, locally-owned options alongside corporate initiatives. The BPS, through its Climate Action Plan and waste reduction programs, actively supports circular economy initiatives, yet the Rennes case underscores that even with municipal backing, the pure-play model faces steep hurdles. Portland’s distinct neighborhoods – from the Alberta Arts District’s concentration of eco-boutiques to the industrial sustainability efforts buzzing around the Columbia Corridor – create varied micro-markets. A zero-waste corner in a suburban Fred Meyer might serve a different need than a refill stall at the Hollywood Farmers Market or a specialized bulk store in Sellwood-Moreland. Understanding these nuances, including how initiatives align with Metro’s regional waste reduction goals or intersect with community development corporations like Proud Ground, becomes crucial for both businesses adapting their models and consumers seeking genuinely accessible, sustainable options.

Given my background in analyzing urban sustainability trends and their local manifestations, if you’re a Portland resident navigating the shifting landscape of zero-waste retail – whether you’re a consumer concerned about access and affordability, a small business owner considering how to adapt your refill model, or an advocate working on policy – here are three types of local professionals whose expertise becomes invaluable:

First, seek out Sustainable Business Model Advisors who specialize in circular economy transitions. These consultants, often affiliated with or recommended by entities like Portland State University’s Impact Entrepreneurs program or the Oregon Sustainability Board, don’t just look at environmental impact; they facilitate businesses stress-test different operational formats (standalone vs. In-store corners vs. Mobile units) against local market data, consumer willingness-to-pay studies specific to Portland neighborhoods, and the intricate logistics of reverse logistics for consigned containers. Look for advisors who can demonstrate familiarity with Oregon’s specific waste management infrastructure and have worked with similar triple-bottom-line businesses facing scale challenges.

Second, connect with Local Food Systems & Supply Chain Analysts. The viability of zero-waste hinges entirely on ethical, transparent, and resilient supply chains for bulk goods. These professionals, who might operate with non-profits like Ecotrust or regional food hubs such as Redd on Salmon Creek, can help businesses or cooperatives map sourcing options that align with both zero-waste principles and regional economic development goals. They assess factors like transportation emissions from bulk suppliers, the social equity implications of sourcing decisions, and how to build resilience against disruptions – a critical lesson highlighted when even established models face pressure. Criteria should include proven experience tracing commodities from regional producers to retail points and understanding Oregon’s agricultural landscape.

Third, engage with Community Resilience Planners focused on neighborhood-scale resource flows. These aren’t just traditional urban planners; they specialize in how resources like food, water, and goods move within and between Portland’s distinct neighborhoods, often collaborating with entities like the Coalition for a Livable Future or neighborhood associations. They can help assess the true accessibility of zero-waste options – not just geographic proximity, but considerations of transit access, pricing equity, and cultural relevance across different communities, from East Portland to the Pearl District. When evaluating them, prioritize those who employ participatory planning methods and have experience linking hyper-local resource initiatives (like neighborhood buying clubs or tool libraries) to broader city goals outlined in plans like the Portland Comprehensive Plan.
