How Did Boxed Water Start?
Boxed water emerged as a response to mounting concerns about plastic waste and its environmental consequences. Entrepreneurs saw an opportunity to offer a product that could break down faster, using renewable and sustainable materials such as paperboard. Brands like Boxed Water Is Better intentionally named their product to highlight that, while perhaps not the best (that honor goes to refillable containers), it is positioned as a better single-use option compared to plastic or aluminum.
What Is in a Boxed Water Carton?
Although marketed as a paper-based solution, boxed water packaging is a complex product made of several layers:
- Paperboard: Typically comprises 66–96% of the total material. This gives rigidity and most of the box structure.
- Plastic Layers: Polyethylene is used as a moisture barrier and sealant in multiple thin layers.
- Plant-Based Components: Increasingly, brands are using plant-derived plastics (e.g., sugarcane-based) for parts like the cap and linings.
- Aluminum Foil: Some aseptic cartons (especially those for shelf-stable liquids) also include a thin layer of aluminum, though many boxed water brands avoid or minimize this.
Thus, a boxed water carton is not simply “a paper box.” Instead, it’s a composite material intended to be lightweight, protective, and adaptable for different shelf lives.
Environmental Impact of Boxed Water
Environmental claims are at the core of boxed water’s marketing. But how well do these claims stand up against scrutiny from life cycle analysis, watchdogs, and advertising regulators?
Life Cycle Assessment (LCA) Evidence
A third-party LCA conducted in 2020 compared boxed water (in paper cartons), premium plastic bottles, and aluminum cans. The findings were as follows:
- Boxed water cartons had lower impacts in every environmental category compared to plastic bottles.
- Plastic bottle production has a substantially higher ozone depletion potential—18 times that of boxed water.
- Plastic bottle blow-molding generated double the global environmental impact relative to boxed water production.
- Aluminum cans had a higher overall carbon footprint (about 200% more) than boxed water, mainly due to the energy-intensive processes of producing aluminum.
Key takeaway: Boxed water performs better than plastic bottles and aluminum cans on most core environmental metrics, especially when it comes to production-related emissions and resource use.
Tree-Planting Initiatives
Boxed Water is Better has promoted its tree-planting programs as part of its environmental commitments, with credible third-party evidence supporting claims that it has planted millions of trees.

Table: Comparative Environmental Impacts (Production Phase)
| Packaging Type | Global Warming Potential | Ozone Depletion | Resource Use | Notes |
|---|---|---|---|---|
| Boxed Water (Carton) | Low | Low | Lowest among options | Significant renewable content, tree-planting programs |
| Plastic Bottle (PET) | High | Very high | Fossil fuel derived | Ozone impact 18x that of boxed water |
| Aluminum Can | Very High | Medium | High (energy intensive) | 200% higher carbon footprint than boxed water |
Recyclability: How Boxed Water Compares
The potential for a package to be recycled is a crucial sustainability metric. All boxed water cartons marketed by leading brands are technically recyclable—but real-world outcomes are more nuanced.
- Certain facilities are equipped to separate and recycle the composite layers of boxed water cartons.
- The practical recyclability depends on infrastructure: in some regions, boxed cartons are not accepted in curbside recycling or are not efficiently processed.
- Plastic bottles are recyclable almost everywhere, though low collection rates and contamination mean many still end up in landfills or as litter.
- Aluminum cans remain one of the most successfully recycled beverage containers globally, with high rates of collection and reuse.
Fact check: According to the National Advertising Division (NAD), claims that boxed water cartons are fully recyclable are considered reasonable if local recycling systems are equipped to process them.
Renewable Materials and Sourcing
One of the main selling points for boxed water brands is the use of renewable, plant-based materials. Yet, the definitions and reality behind these claims merit scrutiny.
- Cartons generally contain between 66% to 96% renewable content—primarily the paperboard layer.
- The remaining material typically comprises layers of plastic (sometimes from sugarcane) and, in some cases, a thin foil layer.
- Some marketing suggests that all the plastic components are plant-based. However, mass balance accounting means this is true only in aggregate—not in each individual carton.
- The Federal Trade Commission’s Green Guides offer flexibility on such accounting, but the NAD recommends clarity for consumers to avoid misleading impressions.
Caveat: NAD recommended boxed water brands clarify their renewable claims and be specific about what “renewable” means—namely, the percentage and type of materials used.
Aluminum vs. Plastic vs. Boxed Water
Environmental comparisons between boxed water, plastic bottles, and aluminum cans often appear in marketing and media. However, regulators have scrutinized the accuracy and context of these comparisons.
Key Points of Comparison
- Life Cycle Emissions: Boxed water has lower climate and ozone impacts during production relative to both plastic and aluminum packaging.
- Material Sourcing: Boxed water is based on a renewable feedstock (trees), while plastic bottles depend on fossil fuels, and aluminum relies heavily on energy-intensive ore processing.
- Recycling Rates: Aluminum cans have the highest actual recycling rate in many markets, plastics suffer from low real-world recycling, and cartons depend on local capabilities.
- Marketing Claims: NAD required boxed water brands to modify or discontinue superiority claims unless appropriately qualified and substantiated.
Table: Packaging Options at a Glance
| Criterion | Boxed Water | Plastic Bottle | Aluminum Can |
|---|---|---|---|
| Main Material | Paperboard, plastic liners, sometimes foil | PET plastic (fossil fuel based) | Aluminum |
| Renewable Content (%) | 66–96* | 0 | 0 |
| Recyclability (theoretical) | Yes | Yes | Yes |
| Recycling Rate (US est.) | Low–moderate | Low | High |
| Key Criticisms | Composite layers hinder recycling, marketing clarity needed | Fossil fuel use, pollution, low recycling rates | High carbon footprint for production |
*Depending on sourcing and plant-based plastic use. Not every carton has the same composition.
Marketing Claims and Greenwashing Risks
A growing body of regulatory oversight is aimed at preventing greenwashing in the beverage packaging space.
- The National Advertising Division (NAD) has found boxed water marketers generally support certain environmental claims (like recyclability and tree-planting) but recommended modification or discontinuation of superior renewable and sustainability claims unless clarified.
- Advertisements should not suggest that cartons are made with “100% plant-based materials” if that is not accurate for each component.
- Comparative claims (“most renewable” or “better than aluminum”) must be qualified according to available data and life cycle analysis, and must reflect that results can vary based on region and recycling infrastructure.
Consumers should approach environmental packaging claims with scrutiny and look for transparency and independent verification. Regulators suggest that unless a claim is fully supported by broad evidence, it should be stated more conservatively and with clear definitions.
The Real Best Option: Reusables
Even though boxed water often outperforms single-use plastic or aluminum on various sustainability dimensions, experts and environmental advocates consistently note that the most sustainable choice is refillable, reusable water bottles.
- Single-use solutions, regardless of material, use more resources than reusing a sturdy bottle many times.
- Reusable bottles (glass, stainless steel, heavy-duty plastic) dramatically reduce waste and emissions per use over time.
- Boxed water is best considered a better single-use fallback—never a substitute for good tap water in a refillable bottle.
Frequently Asked Questions (FAQs)
Q: Are all boxed water cartons recyclable everywhere?
A: No; while they are technically recyclable, actual recycling rates depend on local facilities being able to process the composite material. Many areas lack the necessary infrastructure.
Q: Is boxed water always made from renewable materials?
A: Not entirely. While a high percentage of the carton may be made from renewable sources, certain caps, liners, and sometimes other layers may use fossil-based plastics or aluminum. “Renewable” percentages can vary between 66% and 96% per carton.
Q: What is the environmental impact of boxed water compared to plastic bottles?
A: Independent Life Cycle Assessments indicate boxed water produces significantly less ozone-depleting emissions and global warming impacts during production than plastic bottles.
Q: Does boxed water biodegrade in a landfill?
A: No, boxed water cartons do not fully biodegrade in landfill conditions, mainly due to their composite layers. The idea of them “naturally breaking down” is misleading; they primarily function as a recyclable material if properly processed.
Q: What’s the best way to make my drinking water habits sustainable?
A: Use tap water in a refillable, reusable bottle whenever possible. Reserve boxed water or other single-use packaging for rare occasions when reusable bottles are not practical.
