about 40% of the energy that conventional SBR systems need to treat this type of wastewater.” The system is based on a modular, deployable system, making it simple to install on-site. Hastings noted, “The modular design means Helen’s Hill can double the plant capacity in future, simply by installing a second reactor.” The wastewater plant also includes a control system with HyCONNECT. The remote access provided by HyCONNECT allows Hydroflux specialists and Helen’s Hill staff to remotely monitor the plant with minimal operator input.

Renewable oil produced in plant leaves CSIRO researchers have made it possible to produce oil in the leaves, stems and seeds of plants, in a breakthrough which could mark a milestone for the renewable oils industry. “Previously it has only been possible to extract oil from the oil-rich seeds and fruits of some specialised plants, such as canola, soybean, sunflower, coconut and oil palm,” said Dr Allan Green, innovation leader with CSIRO Agriculture and Food. “What we have been able to do is switch on this high-level oil production in vegetative tissue, such as in stems and leaves, as well.” Dr Green explained that the researchers are using solar energy captured by plants to convert their leaves’ starch reserves into more energy-dense oil molecules, which increases the energy value of the vegetative
