May 11, 2017 – Researchers at Simon Fraser University and Kwantlen Polytechnic University are teaming up to develop sustainable clean-tech solutions that will provide potable water and clean food globally, in areas challenged by climate change and fast-growing populations.
The researchers are recipients of a Natural Sciences and Engineering Council of Canada (NSERC) College University Idea to Innovation grant, valued at more than $725,000.
The project combines the expertise of SFU’s Laboratory for Alternative Energy Conversion (LAEC) and KPU’s Institute for Sustainable Horticulture.
Industry partners include:
• Argus Control Systems, a pioneer company in greenhouse automation and control.
• The B.C. Greenhouse Growers’ Association (BCGGA).
• Nexus Biofuel, a B.C. biofuel plant company capable of converting farm and municipality waste into high quality fuel.
NEXT GENERATION OF ‘CLOSED’ GREENHOUSES
Working with industry partners, researchers are developing and testing the next generation of ‘closed’ greenhouses (CGs) equipped with waste-heat-driven technologies.
SFU researchers, led by mechatronic systems engineering professor Majid Bahrami, the project’s principal investigator, are developing new, waste-heat driven technologies for the next generation of CGs.
These will cover an array of key clean technologies for growing crops and providing potable water that are crucial for closed greenhouses. These technologies will use solar and geo-thermal energy, or waste-heat from biofuel plants, data centers, power plants or other sources.
“Closed greenhouse systems collect and store energy from the sun or other waste-heat sources such as biofuel facilities,” explains Bahrami.
“They are sealed buildings that control temperature, humidity and CO2 concentration for optimum plant growth year-round, and are used to produce sustainable clean food and fresh water, under any climatic conditions.”
Bahrami invented patent-pending Hybrid Atmospheric Water generator (HAWgen) technology, which can derive water from the atmosphere using waste-heat. He has just received the Mohammed bin Rashid Al Maktoum Global Water Award for his invention.
While CGs are operational in some places, Bahrami says there is immense room for improvement in their energy and water consumption as well as their environmental and carbon footprint.
“Providing clean, reliable and sustainable crops is a great priority and a global challenge,” he says. “We are hopeful that this research will set a new course for dealing with this critical issue.”
INSTITUTE FOR SUSTAINABLE HORTICULTURE
KPU’s team, led by Dr. Deborah Henderson, director of the Institute for Sustainable Horticulture, and LEEF Regional Innovation Chair, has developed expertise in new cropping systems specifically related to greenhouse production, and is ready to apply these technologies to crop challenges in KPU’s semi-closed geothermal greenhouse.
“A closed greenhouse can create optimal conditions for reliable food and neutraceutical production year-round,” says Henderson.
“The holdback has always been energy cost, particularly cooling and water consumption. We are hopeful that this research will provide new technology to address these critical capacity-limiting issues, and have the added value of being clean technology.”
Currently, three major crops (tomato, pepper and cucumber) are grown in greenhouses due to their high production rate and tolerance to conditions. Targeted technologies in this project will provide opportunities for other crops, especially those currently imported, allowing growers to expand their crop diversity and build resilience in their businesses.
One area of high interest is neutraceuticals, herbs with dietary supplement and medicinal values, which require accurate climate control. They offer tremendous potential for creating value-added crops and emerging markets for Canadian growers.
While clean energy research is carried out, parallel research into Chinese neutraceutical crops will complement the new acupuncture diploma program at KPU.
The project is one of 37 across Canada sharing in $37.4 million in funding for colleges, institutes and CEGEPs to support applied research and development activities with industry partners.
The projects are funded through NSERC’s College and Community Innovation program, which expands the capacity of Canadian colleges to work with local business in developing new technologies and their commercialization.
