West Kootenay tech innovator hosts circular economy conference

"...“Every year, more than 100 billion tonnes of raw materials globally are transformed into new products; only about 8. 6 per cent of the planet’s materials and resources that we use for these products are cycled back into the economy at the end of their life,” said Circular Economy Leadership Canada’s Paul Shorthouse. “This linear economy puts an enormous amount of pressure on our planet and our natural ecosystem … if we continue with this business-as-usual, we’ll be omitting 65 tonnes of greenhouse gas globally by 2030, when we really need to be heading toward net-zero very quickly..."

Faster, greener technique to improve recycling process for electric vehicle batteries

"...To ensure the environmental and economic benefits from EV batteries are fully realised, Faraday Institution researchers have been focused on the life cycle of the battery - from their first production to their re-use in secondary applications to their eventual recycling. One key stumbling block has been in materials segregation, that is how to remove and separate the critical materials - such as lithium, nickel, manganese and cobalt - from used batteries in a fast, economical and environmentally-friendly way..."

Pretreating nuisance green algae with lye, urea increases bacterial production of biogas

"...To produce biogas from algae, researchers commonly use a naturally occurring process called anerobic digestion, in which a type of bacteria break down the algae and produce a methane-rich gas mixture that can be purified. The resulting methane can be used in the production of heat, electricity, methanol, car fuel, and other clean energy sources..."

Modeling a circular economy for electronic waste

"..."Electronics have huge environmental impacts across their life cycle, from mining rare raw materials to the energy-intensive manufacturing, all the way to the complicated e-waste stream," said Christopher Wilmer, the William Kepler Whiteford Faculty Fellow and associate professor of chemical and petroleum engineering, who leads the Hypothetical Materials Lab. "A circular economy model is well-suited to mitigating each of these impacts, but less than 40 percent of e-waste is currently estimated to be reused or recycled. If our technology is going to be sustainable, it's important that we understand the barriers to e-waste recycling..."

Bacteria converts degraded plastic bottles into vanilla flavoring

"...Developing forms of plastic that don't take centuries to break down after use is a common objective among eco-conscious material scientists, and lately we're seeing how bacteria might offer a helping hand. Scientists at the University of Edinburgh have taken this idea one step further, by demonstrating how an engineered form of E. coli bacteria can be used to turn plastic bottles into vanillin, the primary compound of vanilla flavoring..."
