See how much plastic your bottle habit adds up to over a year.

The math behind it

kg/year = bottles per week × 52 × grams per bottle ÷ 1000. A single-use bottle weighs ~10 g.

7 bottles/week → 364/year ≈ 3.6 kg.

Cut it down?

A reusable bottle can eliminate hundreds of single-use bottles per year.
