Study indicates concrete construction waste can help rid the air of sulfur dioxide, a major pollutant.

When the rubber hits the road: Recycled tires create stronger concrete
June 15, 2017 08:13 AM - University of British Columbia

UBC engineers have developed a more resilient type of concrete using recycled tires that could be used for concrete structures like buildings, roads, dams and bridges while reducing landfill waste.

The researchers experimented with different proportions of recycled tire fibres and other materials used in concrete—cement, sand and water—before finding the ideal mix, which includes 0.35 per cent tire fibres, according to researcher Obinna Onuaguluchi, a postdoctoral fellow in civil engineering at UBC.

Are Bidets More Environmentally Friendly Than Toilet Paper?

While bidets remain unpopular in America, they’re a familiar fixture in bathrooms all over the world. And they raise an inevitable question: Is it better for the environment if you wipe, or should you wash instead?

The answer may surprise you — and could lead you to rethink your next bathroom remodel.

Rooftop Solar Panels Are Great for the Planet—But Terrible for Firefighters

When first responders arrived to the burning home on Eugene Street in Manchester, New Hampshire just after 2 am on January 27, half the home was already up in flames. It was a big fire, but relatively routine: Working in the dark, the firefighters made sure the two residents got out unharmed, and got to work.

Why Don't Green Buildings Live Up to Hype on Energy Efficiency?
May 25, 2017 10:12 AM - Yale Environment 360

Not long ago in the southwest of England, a local community set out to replace a 1960s-vintage school with a new building using triple-pane windows and super-insulated walls to achieve the highest possible energy efficiency. The new school proudly opened on the same site as the old one, with the same number of students, and the same head person—and was soon burning more energy in a month than the old building had in a year.

Scientists explore emerging issues in invasive species research
May 18, 2017 08:31 AM - University of Windsor

A University of Windsor professor is among an international team of scientists examining what challenges and opportunities the future may hold for invasive species research.

Professor Hugh MacIsaac travelled to the University of Cambridge last fall along with 16 other ecologists to reach a consensus on what they believed to be the emerging trends, issues, opportunities and threats for invasive science.

Cities need to "green up" to reduce the impact of air pollution on residents as well as buildings
May 16, 2017 12:04 PM - University of Surrey

The study, just published in the journal Atmospheric Environment, points out that low hedges reduce the impact of pollution from vehicles in cityscapes where there are large buildings close to roads, far more effectively than taller trees. In some environments, trees actually make the pollution more concentrated depending on prevailing wind conditions and built-up configurations.

UBC researcher sees future for flax and hemp as particleboard alternative
April 18, 2017 08:32 AM - University of British Columbia

Wood scientist Solace Sam-Brew envisions a future where Canadian homes are furnished with products made from flax and hemp.

“Both flax and hemp are widely available in Canada, especially in the West,” said Sam-Brew, a recent PhD graduate from the University of British Columbia’s faculty of forestry. “It’s worth considering their viability as alternative raw materials to wood for particleboard production.”
