Josephine Liang, 25, is part of a growing community of "freegans," people who eat recently discarded food to reduce waste. Liang used to shop regularly at the supermarket, then found a cheaper alternative by rummaging through bins, a decision that she says has lowered her weekly food bill to just £5 a week. Liang will wait until shops and cafes close, and then go through their bins to see what she can find. She is saving the money to go travelling.
