Making cleaner, greener plastics from waste fish parts

"...The conventional method for producing polyurethanes presents a number of environmental and safety problems. It requires crude oil, a non-renewable resource, and phosgene, a colorless and highly toxic gas. The synthesis generates isocyanates, potent respiratory irritants, and the final product does not readily break down in the environment..."

Germ-killing, wound-healing, low-cost bandage made from durian husks

"...Although not a huge seller everywhere, durian fruit is consumed in great quantities in countries like Singapore. Scientists there have now developed a method of using its otherwise-discarded husks to create cheap, eco-friendly, antibacterial hydrogel bandages. First of all, hydrogel bandages themselves are nothing new..."

Alberta, Saskatchewan set to lead country in green energy growth

"..."When people think about the Prairies, many of them think about fossil fuels," said Darren Christie, chief economist for the CER. "Interestingly, our projections show they are actually now leading the way in renewable energy growth, while national levels will slow in the next three years. "..."

Plastic is part of the carbon cycle and needs to be included in climate calculations

"...Plastic transports carbon in different ways. For instance, plastic can become incorporated into living organisms, or settle to the bottom of the ocean as aggregates of plastic and organic matter. It can also release greenhouse gases at every stage of its life cycle, from production to transportation to waste disposal..."

Double-duty catalyst generates hydrogen fuel while cleaning up wastewater

"...Hydrogen is a pollution-free energy source when it's extracted from water using sunlight instead of fossil fuels. But current strategies for "splitting" or breaking apart water molecules with catalysts and light require the introduction of chemical additives to expedite the process. Now, researchers reporting in ACS ES&T Engineering have developed a catalyst that destroys medications and other compounds already present in wastewater to generate hydrogen fuel, getting rid of a contaminant while producing something useful..."

Watch: Recycled cotton becomes new fabric

"...At the Department of Chemical Engineering in Lund where Edvin Ruuth works, there is a great deal of accumulated knowledge about using micro-organisms and enzymes, among other things, to transform the "tougher" carbohydrates in biomass into simpler molecules. This means that everything from biological waste and black liquor to straw and wood chips can become bioethanol, biogas and chemicals..."

BLOG: A brief fiscal history of Alberta—marked by spending spikes

"...As the Kenney government prepares to release its 2021-22 budget later this week, it’s grappling with the largest nominal budget deficit in Alberta history—more than $20 billion—due largely to the pandemic. However, Alberta’s previous 2019-2020 deficit of nearly $12 billion was already its fifth consecutive deficit. And its erstwhile golden status as the only province without a net provincial government debt ended in fiscal year 2016-17..."

Big oil invests in Eavor's

"...BP and Chevron have led a US$40 million investment round for a Canadian startup that claims to have developed a unique way to extract energy from geothermal heat on demand, using an unpowered looping fluid design that's already prototyped in Alberta. Solar and wind are scalable renewable resources, but only produce energy when the sun and wind are up, not when the grid needs it. Hydro can respond well to demand, but it's not really scalable; the geometry of your dam dictates the size of your operation..."

Producing more sustainable hydrogen with composite polymer dots

"...How we are to meet future demand for sustainable energy is a much-debated question. One feasible way to go is hydrogen, which can be produced from renewable resources: water and solar energy. But the process requires what are known as photocatalysts..."
