Waste Management in Multi Unit Developments

A project instigated by one of EnviroCom’s Senior Consultants in Melbourne, with the aim of reducing illegal rubbish dumping, reducing contamination of recycling material and reducing waste sent to landfill, has had extremely encouraging early results. The project received funding from the Metropolitan Waste Management Group’s Metropolitan Local Government Resource and Recovery Fund.

Four different approaches were trialled, to educate residents of multi unit developments (MUDs) in how to dispose of their rubbish and recycling items. The cheapest option (installing under-the-lid recycling stickers) proved to be the second most effective in improving the contamination rate, whilst the most expensive option (door knocking residents) was the most effective in all categories. This option, while costing just over $13 per unit, was less than twice the cost of the next most expensive option (bin corral signage), which had a negligible or negative effect on contamination rates, resource loss and illegal dumping. The second cheapest option (mail-out of information to residents) resulted in the second highest improvement in illegal dumping.

Face to face contact is clearly the most effective way to educate residents in how to dispose of their rubbish, and the long term cost benefits outweigh the initial outlay. Contamination of recycled material was reduced from 16.5% to 2.5% while illegal dumping was reduced from 2 cubic metres per week to one third of a cubic metre per week for the whole development– a result which is certainly worth replicating on a wider scale.
