Citizens of the Great Barrier Reef: going beyond our backyard to protect the reef

From place-based to problem-based campaigns, we are seeing a rise in initiatives aiming to foster collective environmental stewardship among concerned citizens across the globe. These international communities have arisen to meet new environmental challenges and seize the opportunities presented by our increasingly connected world. Traditional approaches to community engagement have tended to focus only on the involvement of local people. However, the recently launched Citizens of the Great Barrier Reef initiative highlights the changing nature of community engagement aimed at fostering environmental stewardship. In a globalised world, maintaining treasures like the Great Barrier Reef and other ecosystems affected by global-scale threats demands …

Medical Waste to Produce Durable, Sustainable Concrete

The thousands of tonnes of plastic waste created each year in Australia through dialysis treatment could breathe new life into the construction industry, according to researchers at Deakin University. A team at Deakin’s School of Engineering is behind the new project, which aims to transform the single-use plastic used in the dialysis project into long-lasting sustainable concrete that could perform better than standard concrete. The project is a collaboration between Dr Riyadh Al-Ameri, a senior lecturer in structural engineering, Katherine Barraclough from the Royal Melbourne Hospital and John Agar from Barwon Health’s University Hospital Geelong. It came about when Dr Barraclough and Professor John …

New Tech Could Turn Windows Into Solar Panels

See-through solar cells have been created which could turn windows into small-scale power plants. Researchers at Michigan State University have developed thin, transparent, plastic-like material that can act as an energy-generating coating on windows, and provide additional power when coupled with a rooftop solar installation. While the technology has existed in its early stages since 2015, it is only now developed enough for projects of scale. The technology works by utilising organic molecules within the transparent film that absorb ultraviolet and infrared lightwaves – which are invisible to the human eye – and converts them into electricity by directing these lightwaves to small photovoltaic cells at the edge …

Bunch of Old Bananas or Building Materials of the Future?

Potatoes reborn as insulation, peanuts processed into partition boards and mushroom bricks that grow in five days – just some of the ways the building trade could change its wasteful ways and construct virtuous new cities. In a report released on Wednesday, international engineering firm Arup set out novel ways for an industry that devours raw materials to cut waste. “We need to move away from our ‘take, use, dispose’ mentality,” Guglielmo Carra, European lead for materials consulting at Arup, said in a statement. “What we need now is for the industry to come together to scale up this activity so that …

Greening the Concrete Jungle: How to Make Environmentally Friendly Cement

Cement is the world’s most widely used material apart from water, largely because it is the key ingredient in concrete, the world’s favourite building material. But with cement’s success comes a huge amount of greenhouse emissions. For every tonne of cement produced in Australia, 0.82 tonnes of CO₂ is released. That might not sound like much, especially when compared with the 1.8 tonnes emitted in making a tonne of steel. But with a global production of more than 4 billion tonnes a year, cement accounts for about 8% of the world’s CO₂ emissions. The electricity and heat demands of cement production are responsible for …

How the Search for Mythical Monsters Can Help Conservation in the Real World

After fears the Loch Ness Monster had “disappeared” last winter, a new sighting in May 2017 was celebrated by its enthusiasts. The search for monsters and mythical creatures (or “cryptids”) such as Nessie, the Yeti or Bigfoot is known as “cryptozoology”. On the face of it, cryptozoology has little in common with mainstream conservation. First, it is widely held to be a “pseudoscience”, because it does not follow the scientific methods so central to conservation biology. Many conservation scientists would find the idea of being identified with monsters and monster-hunters embarrassing. Moreover, in the context of the global collapse in biodiversity, conservationists focus their attentions …

Philanthropy’s Role in Creating Sustainable Cities

Philanthropy has an important role to play in creating “time and space” for cities to become sustainable, according to the program director for the sustainable development grantmaking program at the Rockefeller Brothers Fund. Michael Northrop is set to give the Lord Mayor’s Charitable Foundation’s annual Inspiring Philanthropy oration discussing the role of philanthropy in creating sustainable cities. Northrop, who also serves on New York City’s Sustainability Advisory Board, told Pro Bono News philanthropy had created soft capital that allowed cities to innovate. “The most important actors in a city are going to be your mayors and your city councils and …

Three way communication creates place making results

Two years ago, the town of Nambour on the Sunshine Coast was a little lost. It had great ‘bones’ but the surface was looking a little tired. The place was a bit … well, directionless. Fast forward one year, and the local council adopted the Nambour Activation Plan. Unlike many plans, the Activation Plan does not prescribe what must happen, when and at what cost. Rather, it is an ‘enabler’ – providing the webbing and stimulation for locals to define the types of projects and place Nambour wants to be. Fast forward another year to the present, and the catchphrase …

Rushing to renewable energy targets puts sector’s reputation at risk

The last time an entire state blacked out was on the night the Beatles arrived in Sydney in 1964. So what happened in South Australia last week was rare and the repercussions could be vast. The key question is whether that state’s heavy reliance on wind turbines might have increased the risk of a state-wide blackout. More broadly, the event will supercharge concerns over how renewable energy is being integrated into a national grid that was not designed to cope with it. Wind presents two problems. First, it is intermittent, so all of it has to be backed up by …
