In 2001 the PB Sydney Environment Committee purchased a worm farm to help us reduce the amount of organic waste we send to landfill. Since then, the number of worm farms has increased to three as staff numbers have increased.

The worms will eat anything organic, and particularly like fruit (preferably if it’s not too acidic) and vegetables. Being in an office environment, the worms are fed numerous tea bags (they eat around the staples), which they actually enjoy. Separate rubbish bins are provided for food scraps destined for the worms.

The worms generate liquid fertiliser that we sell to staff for a low price. Th e money collected hel ps fund Environment Committee initiatives. Because the Environment Committee believes in reuse, we put the liquid fertiliser in empty orange juice bottles that we collect from lunch-time meetings.
