The Math on Office Plastic Waste Is Worse Than You Think

I run the numbers on office water systems all day. The plastic math is the part that stops people cold, so here it is with the sources attached.

Start with the national number

The bottled water industry's own trade group, the IBWA, reported that Americans drank 16.4 billion gallons of bottled water in 2024, about 47.3 gallons per person. That is the industry bragging, not a critic estimating.

Not all of it is single-serve bottles. Some is 5-gallon jugs, some is gallon jugs. But the half-litre PET bottle is the format that fills breakroom fridges, and it is the format the recycling numbers are about.

Then the recycling number

The EPA's most recent material-specific figures put the recycling rate for PET bottles and jars at 29.1%. In the same year the country generated 35.7 million tons of plastic waste and sent 27 million tons of it to landfills.

So for every ten bottles your office buys, roughly seven do not get recycled. The bin in the breakroom with the recycling logo on it does not change that; it only changes where the bottle starts its trip.

Now do your office

I will show my assumptions so you can swap in your own.

50 employees
One 16.9 oz bottle per person per workday (a conservative figure; most offices that stock bottles go through more)
250 workdays a year

That is 12,500 bottles a year. At the EPA's 29.1% rate, about 3,600 get recycled and roughly 8,900 go to a landfill. Change any of those inputs and the ratio holds: seven in ten bottles are landfill bottles.

Stack 12,500 half-litre bottles and you have a pile that would not fit in most conference rooms. Every year.

Why this shows up in sustainability reports now

Containers and packaging are the largest single slice of US municipal solid waste, which is why plastic packaging has become a line item in corporate sustainability reporting rather than a footnote. A breakroom is one of the few places where a company can cut a measurable stream of it with one purchasing decision.

I sell water systems, so I am biased. But the arithmetic is not mine. A bottleless cooler plumbed to the wall takes the 12,500 bottles to zero. No delivery trucks, no storage closet full of cases, no bin that was never going to solve the problem.

The real question

Your office will consume water. That is not changing. The question is whether you want 8,900 bottles a year going to a landfill to do it.
