Sustainable Processing

sustainable-processing.jpg Processing industries are the backbone of New Zealand, and Massey provides research and training to ensure ongoing success.

Our expertise

Biotechnology

A focus is on improving process yield and productivity through the application of process engineering and molecularbiology and microbiology.

Contact Prof Yusuf Chisti

Chemical and nanotechnology

Improving our knowledge of the underlying chemistry of chemical reactions results in better design and improvement of chemical processes. Increasingly, chemical engineering research is looking to the micro- and nanoscales to provide these insights. Tools such as atomic force microscopy, electron microscopy and synchrotron are being used to collect nanoscale information on a wide range of materials of interest in New Zealand.

Energy

Current research at Massey is looking into strategies for adoption of renewable energy technologies such as wind, biomass, small hydro and passive solar design.

Contact Prof Ralph Sims

Environmental engineering

We are engaged in research around a strong working knowledge of current technologies in combination with state-of-the-art research in environmental microbiology, biotechnology, process engineering design, modeling and scaleup.

Algae

Green fuel may not be so green

So-called green biofuels might not be as good for the environment as scientists hoped, according to Massey research.

Algae can be used to produce a form of green crude, with the possibility of freeing societies and nations from their reliance on fossil fuels, yet this seemingly natural wonder has a dirty secret.

So why aren’t we already topping up our tanks with green biofuel produced from algae? Price. As yet, algal biofuels are many times more expensive than the conventional kinds. But their cost may not be the only barrier. There is also the matter of algae’s environmental credentials which, it turns out, are not entirely impeccable.

In 2009, Professor Benoit Guieysse and his colleagues at the School of Engineering and Advanced Technology at Massey University were surprised to find that nitrous oxide (N2O), also known as laughing gas, was seeping from a batch of microalgae. This was not a good thing. Algae may be good at consuming the greenhouse gas CO2, but, per molecule, N2O has nearly 300 times the ability of CO2 to trap heat in the atmosphere, and is also an ozone-depleting pollutant.
