Do you think Australia does enough to encourage metal recycling? Currently, you only receive a cash incentive to recycle in South Australia and the Northern Territory, and that's only for aluminium drink cans. Having said that, the environmental benefits should be incentive enough, since for every can you recycle, you save enough electricity to power a TV for three hours - electricity that would have otherwise been used to make new aluminium.
A restaurant, school or other establishment that prepares food will typically be required to have a grease trap installed. This is a type of apparatus that fits between the kitchen's drains and the sewer lines and which keeps fats, oil, and grease (FOG) from getting into the sewers and causing clogs. It's important that these establishments keep their grease traps properly cleaned and maintained so they don't back up and cause an overflow, as this is very messy and difficult to clean.
