Waste Reduction
Strategies for Reducing Waste
One of the most important factors in managing waste and preserving the environment is actually reducing the amount of waste that is produced. Strategies for reducing waste include reusing second-hand goods, avoiding disposable products and designing products to be reusable or refillable, repairing broken items and so on. Reducing waste is part of the waste hierarchy, where the most effective strategies are at the top of the pyramid and the least at the bottom. Effective policies include waste prevention and minimisation (including energy use), reuse and recycling, then less effective strategies include energy recovery and waste disposal.
Waste Compactors
Process Systems Services Pty Ltd manufactures two models of waste compactors, both designed for the waste and recycling industry. The first is the PSS Compactor Maxi, designed for high volume, heavy duty waste compaction. It consists of a horizontal ram that compresses the waste into standard industry bins (26m³ – 32m³). One of the primary concerns in its design was safety, so comprehensive fail-safe systems, mechanical interlocks, electrical interlocks and alarms were included to ensure the highest safety standards. It can also be fitted with a dust collector to filter the discharged air.
The second is the PSS Compactor Mini designed for paper compaction into a 600L standard industry waste bin. The benefit of a waste compactor is that it can reduce the volume of waste, making it easier and less expensive to transport, reducing its environmental impact, and helping deal with odour and rodent issues. It achieves a much higher compaction rate than manual filling of bins, about 3:1 (depending on the sort of materials). It also is designed with comprehensive safety mechanisms (interlocks, safety switches, operator protection devices) as well as superior performance. It has two compaction heads which operate vertically and on a cycle basis as waste is dropped into the bin.
