โ“ FAQ

What counts as plastic footprint?

Single-use plastics: water bottles, grocery bags, takeout containers, straws, and product packaging. These often end up in landfills or oceans.

How much plastic does the average person use?

Americans use roughly 300 pounds of plastic per person per year. Much of this is packaging and single-use items.

What are the best ways to reduce?

Use reusable bottles, bags, and containers. Buy in bulk. Avoid takeout packaging when possible. Choose products with less packaging.

Why is plastic recycling so low?

Many plastics are hard to recycle, contaminated, or not accepted by local programs. Reducing use is more effective than relying on recycling.

What is packaging level?

Estimated additional plastic from product packaging (food, toiletries, etc.). Minimal = careful choices; very_high = lots of packaged goods.

How accurate is the weight?

Estimates based on typical weights. Actual varies by product.
