Improve Your Environmental Footprint With The Correct Shredder or Granulator

Each year around 19 million tonnes of waste in Australia comes from construction and demolition, which equates to around 40% of the country's total waste generation. However, only 8.5 million tonnes actually ends up in landfill. Due to the large churn of excess timber, plastics and paper in the industry, everyone involved is continuously working to grow the recovery and recycling rate of all products.

With around 20 million tonnes of garbage making its way to landfills in Australia, it's clear why small and big businesses have taken a strong stance for renewable products. Whether your company has a robust waste management system that utilises compactors and balers, or it offers its goods through biodegradable containers, finding environmentally friendly solutions to product waste is now more readily available than ever.

However, the efforts of mass waste producers are still fairly new, and with China's recent ban on importing landfill it's clear that there's still so much more Australian businesses can do. Helen Millicer, who authored a report regarding kerbside recycling for the state government states that it's still too easy for companies and households a like to get complacent in their recycling efforts: "We have become addicted to the easy system Of putting it into a bin and sending it to China...We're now going to have an extraordinary amount of material that's going to have nowhere to go."

For wooden, plastics, tyres and paper waste, there are two main technologies your business can utilise to reduce the size of your waste: shredding or granulating. In the past you could get away with just having one or the other, or a combination that does both. As long as the basic processes were in place. But now that the machinery has advanced to adapt to the current recycling habits, having the wrong machine in your vicinity can be costing you money, time and hindering the sustainability of your company.

To ensure your business has the right equipment to manage its waste, you need to reassess what materials you need to reduce and to what size the end product needs to be. This will help you determine whether your current shredder or granulator is the right one for you. Here's a simple guide regarding the key differences between shredding and granulating machines:

Shredding Machinery

Shredders are low speed and high torque machines that are designed to take large components and shred them down to around 20-40mm or larger.

Therefore if you know your business needs finer end products a shredding machine won't be able to provide you with the proper solution.

Shredders instead suit those who have items like used tires and want to turn them into larger chips for fuel or drain fill. A shredding machine is also great for reducing plastics.

Granulating Machinery

Granulators are often mistaken for grinders. Due to the two different machine's similar processes of taking larger components and making them smaller. However, the difference is the actual size of reduction. A granulating machine can make components much smaller than a grinder.

With an open rotor design, granulators typically take small components and turn them into 6, 8 or 10mm flakes with 3mm being about the smallest for special purpose applications.

The machinery is readily available for already reduced components to be refined even further. Therefore, granulators suit practices that have materials that could benefit from even more size reduction.

The right waste reduction machine will not only improve the efficiency of your business but also reduce your company's impact on our environment.
