"Unwanted clothing dumped in the bin ends up up along with the rest of your rubbish." "It's a waste to not pass your unwanted clothes to charity" "Most charities have shops in your local high street" "Charities can post collection bags and make door to door collections for your unwanted items" "Clothes that are too worn to be sold can be shredded and reprocessed into new items" are all facts.
