The Environmental Impact of Single-Use Packaging

The Scale of the Problem

Single-use packaging — packaging designed to be used once and then discarded — accounts for approximately 36% of all plastic production globally and roughly 40% of municipal solid waste in the United States by volume. The environmental toll is staggering: an estimated 8 million metric tons of plastic packaging enters the ocean each year, while landfilled packaging generates methane as it decomposes and leaches chemicals into groundwater.

Not all single-use packaging is equally problematic. Corrugated cardboard, while technically single-use in most applications, has a recycling rate above 90% and is biodegradable when it does enter the waste stream. Plastic packaging, by contrast, has a recycling rate below 6% and persists in the environment for hundreds of years. The environmental impact of single-use packaging depends heavily on the material and what happens to it after use.

The Carbon Cost of Making Packaging Once

Manufacturing packaging requires energy and raw materials. Producing one kilogram of corrugated cardboard generates approximately 0.8 to 1.5 kg of CO2 equivalent. One kilogram of PET plastic generates 2.5 to 3.5 kg CO2 equivalent. One kilogram of aluminum packaging generates 8 to 10 kg CO2 equivalent (though aluminum's high recyclability offsets much of this over multiple lifecycles).

When packaging is used once and discarded, the full manufacturing carbon cost is borne by a single use. Reusing the same packaging three times cuts the per-use manufacturing footprint by two-thirds. This simple math is why the waste hierarchy prioritizes reuse over recycling and recycling over disposal — each step up the hierarchy distributes the environmental cost of manufacturing across more use cycles.

Waste Beyond Carbon: Water, Land, and Biodiversity

Carbon emissions capture headlines, but packaging's environmental impact extends far beyond climate change. Paper and cardboard production is a major consumer of fresh water — approximately 10 liters per kilogram of containerboard. Plastic production relies on fossil fuel extraction with its associated habitat disruption and pollution risk. Landfilling packaging waste requires land that could otherwise serve ecological or agricultural purposes.

Packaging litter is one of the most visible environmental impacts. Plastic packaging fragments into microplastics that contaminate soil, waterways, and marine ecosystems. Even corrugated cardboard, when improperly discarded, contributes to urban litter and can clog stormwater systems. The full environmental cost of packaging extends from production through disposal and includes impacts that are difficult to quantify but impossible to ignore.

Practical Alternatives for Businesses

Eliminating single-use packaging entirely is not practical for most businesses, but reducing it is. Start with the highest-impact changes:

• Replace plastic void fill with paper-based alternatives that are curbside recyclable.
• Switch from plastic poly mailers to paper mailers or padded envelopes for lightweight shipments.
• Implement a box reuse program to extend the life of corrugated boxes from one use to three or more.
• Right-size packaging to reduce total material consumption per shipment.
• Choose recycled-content materials that reduce demand for virgin resources.

The Role of Consumer Behavior

Even the best packaging is only sustainable if consumers dispose of it properly. Clear recycling instructions on packaging — using the How2Recycle label system or similar — significantly improve recovery rates. Studies show that packages with clear disposal instructions are recycled at rates 10 to 15 percentage points higher than those without. Investing in consumer communication is one of the most cost-effective sustainability measures a business can take.

Businesses can also influence behavior by making the sustainable choice the easy choice. A returnable packaging system with a prepaid return label removes the friction of return-and-reuse. A box printed with "Please recycle — this box wants to come back as a new box" reminds consumers to act. Small nudges, applied at scale, create meaningful change.
