The significance of Entropy

Entropy is a term used in physics to measure the state of disorder.  The universe is running down – like a clock – increasing its state of disorder.

In order to reverse the process – increase the state of order – work has to be done - i.e. energy expended

It therefore follows that the more disordered  a system is – the more effort is required to induce order

In recycling terms this means it requires a lot of work (energy, impact, expense) to collect a non-homogeneous mixture of recyclables from Australia’s dispersed 8 million households – this type of recycling is less likely to be sustainable
