Estimate your annual plastic waste generation.
Decision Context
Page-specific guidance for using this result in a real planning decision.

Use this page to estimate how much plastic waste your routine creates and which categories of use are contributing the most.

It is useful for household habit review, sustainability education, and deciding which swaps are most likely to reduce disposable plastic use.

The category breakdown is usually more actionable than the total, because reduction efforts work best when they target the repeat behaviors driving the footprint.

Bottle~10g
Bag~5g
Wrapper~1g
Cup~5g

Example

Weekly Usage

Inputs:

Bottles:5
Bags:5
Wrappers:10

Steps:

  1. 1.Weight = (5*10) + (5*5) + (10*1) = 50 + 25 + 10 = 85g / week
  2. 2.Annual = 85 * 52 = 4420g = 4.42 kg
Result:
4.42 kg / year
