Researchers have converted paper waste into green cellulose aerogels that are non-toxic, ultralight, flexible, strong and water repellent. The material is suitable for oil spill cleaning, heat insulation, packaging, drug delivery and more. [ + ]

Researchers have developed a filtration system that is very efficient at removing various toxic heavy metal ions and radioactive substances from water. [ + ]

Emerson Process Management has completed a combined cycle optimisation project that generated operational improvements and slashed average fuel usage at a large power-generating unit operated by one of the largest utilities in the US. [ + ]

Researchers have created a new type of smart window that could cut window-cleaning costs, reduce heating bills and boost worker productivity. [ + ]

A heavy-vehicle washdown facility, opened in the town of Dalby, Queensland, will minimise and control the spread of weed seed throughout the region. [ + ]

The first Australian installation of the Siemens Demand Flow energy optimisation system at Robina Hospital in Queensland is already exceeding targets and on track to save enough electricity in its first 12 months to run the MCG light towers for a year. [ + ]

Bredel hose pumps have tackled tough media such as kieselguhr and crude oil with ease, indicating that the robust pumps are suitable for extreme tasks. [ + ]

Dennis Benson says there are three main factors why Australian wastewater plants are making the switch to screw blowers: controllability, reliability and reduced energy usage. [ + ]

A German cheese producer has cut its energy costs with the introduction of a centralised vacuum system from Busch. [ + ]

Researchers from Lund University in Sweden have discovered that drinking water is to a large extent purified by millions of 'good' bacteria found in water pipes and purification plants. So far, the knowledge about them has been practically non-existent, but this new research is about to change that. [ + ]

The Cape housing project is said to be Australia's most energy-efficient housing development, with minimum standards of 7.5-star energy efficiency, 2.5 kW solar and 10,000 L water storage per home. [ + ]

The Karlsruhe Institute of Technology has developed Powercaps — energy storage systems that combine the advantages of batteries and supercapacitors. [ + ]

Infratech Industries has sold its floating solar system to the City of Holtville, California, where it will power the city's new water treatment facility. [ + ]

Materials scientists have manufactured a revolutionary material, called a boron nitride nanosheet, that can absorb up to 33 times its weight in oils and organic solvents. [ + ]

Epson has developed a compact office papermaking system, the PaperLab, capable of producing new paper from securely shredded waste paper without the use of water. [ + ]
