Leamington – A unique partnership involving a local biopolymer compounding company, technology from the University of Guelph and a food packaging company could make single serve coffee pod garbage a thing of the past.

Competitive Green Technologies of Leamington is working with the world’s leading single serve coffee brand owners on a recyclable and compostable version of the single serve coffee pod.

Its key structural components are made from bio-composites using biomass like coffee chaff, a waste stream of the coffee industry. Other biomass such as corn fiber, bio-carbon and miscanthus are also used, ensuring added markets for agriculture. Continue reading

Bubble-based aeration for more sustainable aquaculture

Guelph – A new pump that uses air to circulate water is being developed at the University of Guelph, and it could make some favorable waves in the aquaculture industry.

Known as the Airlift Pump, the device is intended to replace costly and energy-hungry circulation machinery at both inland and open-water fish farms. It’s versatile, energy efficient, and even has some unintended and rather positive side effects on water quality.

According to principal researcher Wael Ahmed, associate professor at Guelph’s School of Engineering, the Airlift Pump is an aeration system using a specially designed dual air injector, and runs using the physics of buoyancy. Continue reading

New propagation trays improve tree health and growth

Vineland – The differences between two young oak trees in a greenhouse at the Vineland Research and Innovation Centre (Vineland) are immediately noticeable. Not only is one twice the size of the other, but its root base is much thicker.

Both trees were planted into the same growing medium on the same day last April. The difference is that the smaller one was grown in a traditional black plastic plug tray, common in the nursery industry, while the larger one was grown in a revolutionary new propagation tray designed by Vineland.

Dr. Darby McGrath is a nursery and landscape research scientist who has been at Vineland since 2013. A lot of her work in the past has focused on urban tree projects – with a special interest in growing trees that will survive and thrive along Canadian highways or urban boulevards.

“Those are challenging plantings,” McGrath explained. “It’s the opposite of what a tree would want.” Continue reading

What’s in healthy soil?

New research looks at how soil health changes over time

Thunder Bay – Do the best yields come from the healthiest soil? Not necessarily. But new research suggests farm management practices can impact soil health – and improve a crop’s chance of thriving when times get tough.

Dr. Amanda Diochon, a professor in the Department of Geology at Lakehead University, is part of a multi-partner research study that aims to develop an improved soil health test for Ontario.

The project focuses on how different management practices impact soil health from four Ontario sites – in Ottawa, Delhi, Elora and Ridgetown. For Diochon’s part, she’s tracking how components of organic matter change over time. Continue reading

Ontario company takes world’s first plant-based carbon black substitute to market

Leamington – Using specially grown crops and agricultural plant wastes, a local company has commercialized the world’s first plant-based substitute for carbon black.

Black plastic gets its colour from carbon black, a co-product of oil refining that is both non-renewable and deemed a possible human carcinogen by the International Agency on Research on Cancer.

There has been no alternative until now, with Competitive Green Technologies’ development of BIOBLAKR®, a bio-carbon using patent-pending technology invented at the University of Guelph’s Bioproducts Discovery and Development Centre. Continue reading
