Our clients save 18m single-use bottles and 5,000 tones in carbon – what are you waiting for? 

Hospitality has spent the last decade getting serious about sustainability. Kitchens have tackled food waste, buildings have chased energy efficiency, and single-use plastics have been designed out of everything from straws to toiletries. Yet one item still travels thousands of miles, sits in storerooms, and is thrown away after a single pour: the bottle of water on the table.

Water is the most-served product in any venue, and for many operators it remains one of the least examined from a sustainability perspective. As guests grow more discerning and reporting requirements tighten, that’s beginning to change. On-site filtration, turning mains water into premium still and sparkling served in reusable bottles, is emerging as one of the simplest, highest-impact sustainability moves a venue can make. To understand why, it helps to follow a bottle of water from cradle to grave.

The carbon challenge

Bottled water carries a carbon cost out of all proportion to what’s inside it. The UK gets through roughly 7.7 billion single-use plastic water bottles a year about 38.5 million every day and each one has been manufactured, filled, packaged, transported and chilled before it reaches a guest. Estimates suggest bottled water can have a carbon footprint hundreds of times higher than the equivalent volume of tap water, which arrives through existing infrastructure with almost no marginal emissions.

For a busy hotel or restaurant, the numbers add up quickly. A single mid-sized venue can move through tens of thousands of bottles a year, each contributing to a Scope 3 emissions figure that increasingly has to be measured, reported and reduced. As net-zero commitments filter down from group boardrooms to individual properties, water is no longer too small to count. It is, in fact, one of the easier wins, a place where a single operational change removes an entire recurring line of emissions rather than trimming at the edges.

Packaging and production

The instinct, when plastic falls out of favour, is to reach for glass. It feels premium, it feels natural, and it feels greener. The evidence tells a more complicated story.

Producing glass is energy-intensive: furnaces run at around 1,500°C, and the raw materials must be melted and formed for every bottle made. Life-cycle assessments from a widely cited 2020 University of Southampton study to more recent analyses in 2024 have repeatedly found that single-use glass can carry a higher overall environmental impact than plastic across several measures, including climate change. Plastic, meanwhile, brings its own production burden: it is made from fossil-fuel feedstock, and its manufacture locks carbon into a product designed to be used once.

The uncomfortable truth is that there is no “good” single-use material. Choosing between plastic and glass is choosing which environmental problem you’d prefer to own. The only packaging that genuinely reduces impact is packaging used many times over, a reusable bottle whose manufacturing footprint is spread across years of service rather than a single serving.

Transportation emissions

Where glass really struggles is on the road. A glass bottle is three to five times heavier than a plastic one, and every kilogram of extra weight is a kilogram that has to be trucked from bottling plant to distribution centre to venue often across long distances, and sometimes from overseas. Heavier loads mean more fuel, more journeys, and more emissions for the very same litre of water.

Bottled water is, in essence, a product that is mostly weight and mostly local everywhere it’s sold yet it is routinely shipped hundreds or thousands of miles. On-site filtration eliminates this entirely. When water is produced at the point of use from the mains supply already plumbed into the building, the “transport” leg of its footprint effectively disappears. There are no pallet deliveries, no wagons, no road miles just water, made where it’s poured. For venues serious about their supply-chain emissions, cutting a whole category of inbound logistics is a rare and clean saving.

Waste management

Then there’s the end of the bottle’s life. Despite decades of kerbside recycling, the UK’s plastic-bottle recycling rate has been stuck at around 57% since 2012, meaning billions of bottles a year still slip through to incineration, landfill or the natural environment. Glass fares better on recyclability in principle, it can be recycled endlessly without loss of quality but only if it’s actually collected, and its weight makes that collection carbon-heavy too.

For operators, waste is also a daily operational headache: crates to store, bins to fill, and collections to pay for. Incoming regulation is sharpening the point. With a Deposit Return Scheme on the way, the administrative and financial cost of handling single-use containers is only going to rise. Reusable systems sidestep the problem altogether. A bottle that is washed and refilled hundreds of times generates almost no waste stream, removes the recycling burden, and takes a venue out of the reach of tightening single-use rules before they bite.

The filtration answer

Put the four challenges together; carbon, production, transport and waste and a clear pattern emerges. Every one of them stems from the same root cause: treating water as a manufactured, packaged, shipped, disposed-of product rather than a resource that is already on tap.

Modern filtration flips that model. High-quality systems take mains water and transform it into chilled, great-tasting still and sparkling water, served in durable, reusable bottles that can carry the venue’s own brand. The environmental case is compelling. No single-use packaging, no transport emissions, no waste stream but so is the commercial one. Removing the cost of buying, storing, and disposing of bottled water typically saves venues significantly, often while raising the quality of what reaches the guest.

Sustainability and premium service, so often framed as a trade-off, turn out to point in the same direction. The venues leading here aren’t sacrificing guest experience to do the right thing; they’re discovering that a beautifully presented, locally made, waste-free glass of water is simply a better product.

At EcoPure Waters, this is the thinking behind everything we do because the most sustainable bottle of water is the one that was shipped once, never binned, and never single-use in the first place.
