Wastewater biosolids have typically been considered a waste product and management has focused on disposal and volume minimisation. However, with rising energy costs and the focus on sustainability, lower carbon footprint and energy independence within utilities, there is increasing interest in recovering the energy inherently available in biosolids.

Sustainable water management and water-sensitive urban design is best achieved by a combination of underground in-system measures and pre-system surface treatments. Together with its underground solutions, Rocla now has stormwater treatment products from enviss for at-source surface treatment applications.

The application of two-stage turbocharging technology on Wärtsilä diesel engines has been developed through close cooperation between Wärtsilä and ABB Turbo Systems. Wärtsilä is focusing on developing advanced engine technology which, with the turbocharger, is able to reach the highest possible performance and become a cost-effective commercial solution. ABB Turbo Systems is delivering the turbocharging technology with defined performance in terms of airflow, pressure ratios and efficiency.

Troubleshooting energy efficiency for buildings may feel like searching for a needle in a haystack; but for the sustainability team at real estate group Mirvac, it’s all in a day’s work.

The National Water Commission has called for mining activities to be incorporated into water access and planning frameworks that are compliant with the National Water Initiative.

A Melbourne Zoo research project, to test a water treatment process to better manage bacteria levels in the Pygmy Hippopotamus pool, has secured funding through round seven of the Smart Water Fund.

With Queensland businesses reeling from a progression of double-digit electricity price hikes in recent years combined with a highly competitive commercial property rental market, many property owners are looking for a new competitive edge to help attract increasingly discerning tenants who are seeking smart ‘green’ buildings with low electricity consumption.

Peacock Bros and Software Integrators have joined forces to produce a real-time waste management solution for truck fleets working on government waste management contracts. The solution, first developed for waste collection contractor J R Richards & Sons, includes real-time monitoring of every truck’s position, instant recording of waste bin pick-ups and a full history of the trucks’ activities during the day, including trips to the tip for unloading, breaks and time spent travelling versus time spent collecting.

Maroochy Shire on the Sunshine Coast has an extensive waterway network that adds much to the area’s splendour and makes it a desirable place to live. However, the more people migrate to the area, the greater the threat grows to its catchments and waterways. Today, stormwater and agricultural run-off as well as nutrients from treated sewage discharge pose major risks to the health of the Maroochy River estuary.

A number of key renewable energy and energy-efficiency initiatives have been announced as part of the 2010-2011 Australian Federal Budget. Treasurer Wayne Swan said the government accepts the science of climate change and the need for combined global and domestic action. A number of industry associations welcomed the budget speech saying that energy efficiency and smart electricity networks could be an important part of the solution.

GBCA has launched a new Green Star rating tool for industrial facilities to support the sustainable planning, design and construction of high-performance industrial buildings.

Environment Victoria has welcomed the state government’s Green Jobs Action Plan released by Premier Brumby.

In the 10 years since it began operations, the National Australian Built Environment Rating System (NABERS) has become a leader in assessing the environmental performance of buildings. Adding even more significance to NABERS, coming of age is the federal government’s scheme requiring office building energy efficiency to be disclosed at sale or lease, which is expected to commence in the second half of this year.

As Environmental Management Systems (EMS) have now become an essential part of our standard operating procedures and thought processes, it is becoming increasingly necessary for field and operational staff in the industries of engineering, manufacturing, construction and mining to take on the responsibilities of the supervision of on-site environmental compliance.

At present there is an immense research effort directed towards improving our understanding of the dynamics of the Earth system. Twenty-nine of the world’s leading Earth-system scientists have recently summarised the reasons why they are so worried about the future.
