U of G Eco-Friendly Flowerpots Blossom in U.S., Canada

July 04, 2014 - News Release

Affordable, eco-friendly flowerpots — made with University of Guelph technology — have hit the market. They’re on the shelves of 2,500 Kroger stores in the United States and 33 Lowe’s stores in Canada, and soon will be featured in Home Hardware stores.

The pots contain recycled plastics and up to 30 per cent bio-fibres. They were developed by a team led by Amar Mohanty, a professor in the Department of Plant Agriculture and School of Engineering, and director of U of G’s Bioproducts Discovery and Development Centre (BDDC).

The team included the U of G Catalyst Centre and industry collaborators Competitive Green Technologies and the Myers Industries Lawn and Garden Group.

The resin in the bio-composite pots is made of bio-fibres from miscanthus grasses but could also come from wood, oat hulls, soybean hulls or spent coffee grounds.

The researchers wanted to create new bio-resin compositions that meet or exceed the physical characteristics of traditional plastics for the same price, says BDDC researcher and engineering professor Manju Misra. “Not only are the bio-composite flowerpots comparable to traditional oil-based flowerpots in quality and in price, but they also help to reduce carbon dioxide emissions.”

Steve De Brabandere, associate director of the Catalyst Centre, which oversees the University's intellectual property management and technology commercialization, said bio-composite flowerpots offer environmental and economic benefits. “They give consumers the option to have a lower carbon footprint without additional costs.”

Misra said researchers conducted dozens of trials and revisions over two years to achieve consistent melt flow, smell and impact strength comparable to traditional resins.

The project shows that bio-composite products are economically competitive while offering the mechanical qualities of plastic, she says. “BDDC hopes to continue the trend with the development of bio-composite car components.”

The BDDC opened in 2008, and its researchers are studying ways to use soy, wheat, corn and other crops to make everything from car parts and furniture to fuel. They also investigate new crops for use in composite materials.

Funding for this project was provided by the Ontario Ministry of Agriculture, Food and Rural Affairs; the Canada Foundation for Innovation; the Natural Sciences and Engineering Research Council; the Hannam Soybean Utilization Fund and Ontario Research Fund; and Research Excellence Round-4 from the Ontario Ministry of Economic Development and Innovation.
