How We Calculate This

Annual waste = Σ(weekly items × grams per item × 52) / 1000. Item weights from published sources: PET bottle 30g, carrier bag 6g, straw 0.5g, takeaway container 25g, food packaging 15g, other 10g.

Frequently Asked Questions

How accurate are these weight estimates?

Weights are based on published averages: a 500ml PET bottle is about 30g, a lightweight supermarket bag is 5-7g. Actual weights vary by brand and type, but these provide reasonable estimates.

How much plastic waste does the average person generate?

The global average is about 50 kg per person per year, but this varies widely. The US and Australia average over 100 kg/person, while some countries are below 20 kg.

What happens to plastic waste?

Globally, only about 9% of plastic is recycled, 12% is incinerated, and 79% ends up in landfills or the environment. Even "recyclable" plastic often isn't recycled.

How can I reduce my plastic waste?

Use reusable water bottles, shopping bags, and containers. Avoid single-use straws and cutlery. Choose products with less packaging or recyclable/compostable alternatives.
