• Cloth nappies cost between £100-£400 as opposed to disposable at £800-£1,200 for the 2.5 years of normal nappy use.
• 3 billion nappies are thrown away in the UK each year with 90% going to landfill. They can take up to 500 years to decompose.
• Disposables make up 4% of total household waste and up to 50% of that of families with one baby
• Disposable nappies use up to 5 times more energy to produce than cotton ones – that's including the washing process .
• Seven million trees are felled every year in Canada and Scandinavia to supply the pulp for disposables sold in the UK.
