Mechanism and conditions

Consider reusable nappies with efficient washing

BeforeUsing disposable nappies for every change

AfterReusing washable nappies with suitable care

Clean, use again, repeat: the number of uses and cleaning change the life-cycle result.

Read the mechanism and conditions

Life-cycle studies find potential climate benefits from reusable nappies under suitable washing, drying and reuse conditions. Repeated use also reduces discarded single-use products.

There is no winner on every environmental measure: water, electricity and other impacts also matter. Follow hygiene instructions and consider family circumstances. Do not count a separate laundry saving twice.
