There is a myth entrenched in the hospitality industry: that adopting sustainable practices means sacrificing something. Quality, aesthetics, functionality, or the customer experience. That the green path is inevitably a path of compromise.
It is a costly myth. And it has less and less basis in reality.
The bars and establishments leading in customer experience today did not choose between being profitable and being responsible. They integrated both into a single value proposition, and they did so through concrete operational decisions, not just statements of principle.
This blog is a practical guide to doing exactly that: building a sustainable bar without the customer noticing a difference in their experience—and, in many cases, making them perceive it as even better.
Before talking about solutions, it is worth sizing up the industry's specific problem.
A medium-volume bar serves between 200 and 500 drinks per night. Each drink typically involves one or two straws, a disposable cup for terrace service or takeout, and in many cases, cutlery or stirrers. Multiply that by the number of operating days per year, and you get a volume of disposables that, in conventional plastic, represents a significant contribution to a global problem that is already urgent.
Globally, about 380 million tons of plastic are produced annually, and barely 9% is effectively recycled. (Geyer et al., 2017, Science Advances). Single-use disposables—exactly what a bar uses daily—represent a disproportionate fraction of that volume and are one of the most difficult categories to manage at the end of their useful life.
For the hospitality industry, this is not just an environmental issue. It is a regulatory, reputational, and market risk that is already impacting daily operations.
There is a growing gap between what the consumer expects and what many establishments still offer in terms of sustainability.
According to NielsenIQ (2023), consumers under 40 are leading this movement, with 72% demanding products with a lower ecological impact. In the context of a bar, this translates into something very concrete: the straw you use to serve a mezcal or a cocktail carries an implicit message about your establishment's values. And that message is being read.
Sustainable products not only reduce a restaurant or bar's carbon footprint, but they also elevate the perceived value of the experience, creating emotional connections and stories worth sharing.
In business terms: a customer who chooses your bar partly because it aligns with their values is a more loyal customer, more likely to recommend you, and harder to lose to the competition.
Disposables are the most frequent point of contact between your bar and conventional plastic. They are also the most visible change for the customer and the fastest way to communicate a stance.
A common mistake is replacing plastic with paper and assuming the problem is solved. It isn't. Paper straws fall apart in iced drinks, alter the flavor of delicate cocktails, and create an inferior user experience that customers notice and comment on.
The alternative that solves this without compromise is bio-based disposables made from agave fiber, like those from Penka. Agave bagasse accounts for about 40% of the plant's total weight and was historically considered waste. Through grinding, drying, and transformation processes, that bagasse becomes PolyAgave®, a patented plant-based bioplastic that maintains the strength and functionality of traditional plastic, but with a significantly lower environmental impact.
The practical result: a straw that holds up in a drink, doesn't bend, doesn't fall apart, doesn't alter the flavor, and has a visual finish that communicates quality. For a bar with a premium identity, that isn't a sacrifice. It's an upgrade.
The Penka line covers every format a bar needs: 15 cm cocktail straws for short drinks, 18 cm stirrers in natural and black versions for bars with a refined aesthetic, standard 21 and 26 cm straws for long drinks, and jumbo and boba versions for frappes and tapioca drinks. There are also 16 oz biodegradable cups for terrace service or takeout.
Quantified impact: for every ton of products made with Penka bioplastics, more than 3,000 kg of agave byproducts are reused, nearly 150 liters of oil consumption are reduced, and 450 kg of CO₂ emissions are prevented from entering the environment.
A sustainable bar isn't built only by what it serves the customer. It is also built by what it buys. Supplier selection is a strategic lever that many establishments underutilize.
The relevant questions when evaluating a supplier from a sustainability perspective are concrete: Does the material have independent certification to support its environmental claims? Is the supply chain traceable? Does the production process generate waste that is managed responsibly?
In the case of disposables, the difference between a supplier with FDA, USDA Biobased, and verified BPA-free certification, and one that simply claims to be "eco" on its packaging, is the difference between a bulletproof purchasing decision and one that could become a reputation issue if a customer or auditor questions it.
The customer's experience at the bar ends when they walk out the door. Waste management begins there.
A bar that adopts sustainable disposables but lacks a clear protocol for their final disposal is only solving half the problem. Bio-based materials like PolyAgave® are 100% recyclable, but that attribute only creates value if there is a system in place to leverage it.
Concrete actions in this area include: source separation of waste within the operation, identifying local waste management providers with the capacity to handle bio-based materials, and internal communication with the operations team regarding the correct protocols.
This is also high-value content to communicate to the customer: a bar that explains how it manages its waste, with real data, generates more credibility than one that just puts a green logo on the menu.
One of the most missed opportunities for bars that have already made sustainable decisions is communication. Most make the change and don't talk about it. That is a strategic error.
There is a deep coherence in using products made from agave within an event or establishment dedicated to agave spirits. Agave not only gives rise to the drink, but can now also participate in the entire consumption experience.
For a mezcal, tequila, or Mexican cocktail bar, serving drinks with agave fiber straws is more than just an environmental choice. It’s a narrative. It’s about coherence between the origin of the drink and the object used to consume it. That is the kind of detail a discerning customer notices, comments on, and remembers.
The touchpoints where this comes to life: the menu, the staff briefing, the establishment’s social media, and—for higher-end bars—table notes or active conversations between the bartender and the guest.
The final component, and often the most overlooked, is training. A bar can have the best disposables on the market and the most efficient waste management system, but all that effort is diluted if the team doesn't understand it, communicate it, and practice it consistently.
Sustainability training for hospitality teams doesn't have to be complex. It needs to be specific and applied: what materials are used, why they are better, what the supporting certification says, how to respond when a customer asks, and how to manage waste correctly at the end of each shift.
A team that understands and believes in their establishment's decisions communicates them naturally. And that authentic communication is worth more than any marketing campaign.
At Mundo Mezcal, Penka demonstrated that disposables can stop being a problem and become part of the solution. Through their straws and utensils made from agave fiber, the brand showed that disposables can be consistent with the philosophy of mezcal: respect for the land and full utilization of the plant.
Bartenders, brands, and consumers began to question what other elements of the event could be transformed under a circular logic. Penka wasn't just present; it sparked a reflection.
That is exactly the kind of impact a bar can replicate in its daily operations: not just reducing its footprint, but becoming a space where sustainability is part of the experience and the conversation.
In a market where greenwashing is rampant, certifications are the most valuable asset a bar can communicate through its suppliers. When an establishment can say its disposables are FDA-approved for food contact, USDA-certified biobased, BPA-free, and manufactured with patented technology, it isn't making a promise. It is presenting evidence.
That level of rigor in selecting supplies is, in itself, a message about the establishment's standards. And customers who seek that coherence notice it.
Regulations on single-use plastics are advancing in Mexico and around the world. The European Union has banned the most common disposable plastics since 2021 (EU Directive 2019/904, European Parliament), and local legislation in Mexico is multiplying state by state.
Bars that make the change today aren't reacting to an obligation. They are getting ahead, with time to do it right, with a built-in narrative, and with customers already loyal to those values.
Those who wait until they are forced to act arrive in a rush, with no story to tell and nothing to set them apart.
Building a sustainable bar isn't an act of altruism. It’s a strategic decision for competitive positioning with a measurable return: through brand differentiation, high-value customer loyalty, and regulatory foresight that avoids future costs.
The customer experience isn't sacrificed. It’s enriched.
