Disposing of NDD waste: CDEnviro

Disposing of non-destructive digging (NDD) or hydro excavation waste can incur high disposal costs due to its solid/liquid state and weight.

As regulators tighten transport restrictions off the back of an increasing need for urban recycling solutions, the payload per truck may be reduced.

CDEnviro aim to provide efficient dewatering solutions for NDD waste to reduce landfill disposal costs. Its solutions recover up to 85 per cent of water and sand which would have otherwise been sent to landfill. The recovered sand can be reused or provide an additional source of revenue. The end result leads to greater sustainability, reduced disposal costs, a secure method of processing and less business time and money spent on transportation.

One product designed to deal with this difficult waste is the G:MAX. G:MAX uses vibrating platform screen technology in a dual stage washing and recycling system for any solid/liquid mixture that requires classification or dewatering. It removes the particles that cause wear, efficiently removing grit, thus maximising product yield and minimising waste volumes. The recovered grit can be used to offset virgin resource extraction.

The G:MAX aims to boost efficiency through PU splash guards, rubber spring mounts and the ability to continuously process the incoming waste. Guards maximise material and water retention, resulting in a safer and more efficient site. The technology can also be used with other primary, secondary and tertiary water treatment solutions to reduce any necessary contaminants.

Downer partner with CDEnviro for Sydney detritus processing facility

A new Detritus Processing Facility in Rosehill, NSW, will divert more than 21,000 tonnes of waste annually from landfill, to be separated, cleaned and sorted into valuable products and materials for reuse.

The facility, opened by construction company Downer and partnered with CDEnviro, can recycle several different types of materials from everyday waste streams.

Materials such as organic matter, sand, gravel, metals and plastics are able to be separated and then sold for reuse.

Downer’s Executive General Manager Road Services Dante Cremasco said the Detritus Processing Facility creates economic, social and environmental value for material that would end up in landfill, or end up as a pollutant in our natural environments.

“The Rosehill Detritus Processing Facility is capable of cost effectively processing, separating and cleaning upwards of 25,000 tonnes annually from everyday waste streams such as street sweepings or stormwater. Approximately 85 per cent of it is then converted into meaningful streams of use such as organic matter, sand, gravel, metals and plastic,” he said.

“The facility is about pulling product, not pushing waste, as these products can be utilised in compost, asphalt for roads that Downer builds and building materials,” Mr Cremasco said.

The facility is able to support the optimisation of street sweeping operations in metroplitian Sydney, which aims to enable some street sweepers to complete more than one load per shift.

“The proximity of the facility to street sweeping operations in metropolitan Sydney will see further benefits through improved efficiency with shorter distances travelled by street sweepers. This will in turn allow for improved productivity, reduced fuel consumption and longer equipment life.”

NSW Environment and Protection Authority (EPA) Director Resource Recovery Kathy Giunta said the EPA is committed to supporting research and the introduction of new technologies to boost recycling in the state.

“This project is one of several the government has supported through the Recycling Innovation Fund, a part of Waste Less Recycle More initiative and is a good example of innovation in recycling,” she said.

CDEnviro expands team in Australia

Waste and recycling systems provider CDEnviro is expanding its team in Australia with the relocation of Ryan O’Loan, Business Development Executive.

Ryan was based in the UK but will move to Melbourne to strengthen the organisation’s existing business development team in Australia.

Ryan will develop market opportunities and provide support for new CDEnviro customers across Australia.

He has worked for CDEnviro for three years and prior to that was Project Engineer for a major food processing company in the UK. CDEnviro noted his experience in the landfill diversion and environmental remediation sectors of the company will be a particular asset to the Australian market.

“Ryan’s relocation to Australia forms part of our business expansion strategy for this region. It’s a market that is growing at a fast pace, and Ryan’s expertise will be of great benefit to the region,” said Darren Eastwood, CDEnviro Business Development Director.
