Keep Wipes Out of the Pipes campaign gains international recognition

Keep Wipes Out of the Pipes campaign gains international recognition

Senior media and PR advisor at Sydney Water, Peter Hadfield, accepted the award in Singapore, and also made a presentation on the campaign at the Asia Pacific Communications Summit.

Inside Waste caught up with Hadfield when he returned to the country to get his thoughts on the recognition, how the campaign has gone thus far, what’s next, and what we’ve got to look forward to in this space.

Inside Waste: How important has it been getting the message out about the issues that we face associated with wet wipes being flushed? Read more

Scientists discover new catalyst to turn CO2 into ethanol

Scientists discover new catalyst to turn CO2 into ethanol

The researchers were originally attempting to make a material called grapheme but failed because they did not have the correct equipment.

Instead, they created another new hybrid material consisting of tiny spikes of carbon and copper spears on a surface of silicon, only a few atoms thick.

According to ORNL’s Adam Rondinone, lead researcher on the project, the new catalyst was discovered somewhat by accident when they were trying to study the first step of a proposed reaction, and instead realised that the catalyst was doing the entire reaction on its own. Read more

Blockchain P2P trading to support transition to a distributed energy future

Blockchain P2P trading to support transition to a distributed energy future

Using blockchain-enabled peer-to-peer (P2P) trading to support this transition could be one of the solutions to those challenges, argued David Martin, co-founder and managing director of Power Ledger, during his keynote address at the All-Energy Conference in Melbourne.

According to Martin, the system that we’ve designed and the plans for the systems that we have set out in front of us are based on a historical and dated view of how the system worked. Read more

Giving insights into what prompts significant change in water management

Giving insights into what prompts significant change in water management

Wastewater infrastructure enables cities to develop economies to grow and communities to thrive, but is also a major source of global greenhouse gas emissions – primarily due to inherent inefficiencies.

According to a new research paper by Xylem, Australian provider of water and wastewater solutions, the answers to some of these challenges are already available today, with existing high efficiency wastewater management systems significantly cutting harmful emissions without adding costs to current operations.  Read more

Insights into GHD's transformational engineering projects in WA

Insights into GHD’s transformational engineering projects in WA

The project diverts water from Bayswater Brook into the reconstructed wetland, which passively treats the water and reduces pollutants flowing into the Swan River.

The project is expected to prevent 1.35t of nitrogen, 200kg of phosphorous, and around 40t of sediment and other rubbish from entering the river.

Key considerations and advice (technical/technology/processes, etc) provided during the project

The design of the wetland has been informed by a detailed understanding of the water and nutrient balance based on hydraulic investigations, site surveys, groundwater and wetland water level logging, and water quality monitoring. Read more
