Research & Technology

RESEARCH has already begun for the founders of the CRI Council. In 2010, an important study and position paper on drywall recycling was issued, by the group, then called the Construction Recycling Initiatives Task Group. In depth understanding on building materials and technologies is important, and universities as well as many organizations have expressed a genuine interest to come together to fast forward research on materials, technologies and other related matters.

RYERSON UNIVERSITY researchers received funding to work in collaboration with the CRI Council in seeking construction waste management solutions in June 2012. Professors Jane Hao and Mark Gorgolewski, along with Master of Building Science student Joseph Earle received the Ryerson Dean’s Research Fund connector grant, enabling industry and academia to work together to find practical solutions to problems faced by industry and areas requiring further research. CRI Council was chosen as an industry partner after participation by a Ryerson delegation in the International Leaders workshop held in Wakefield, Quebec in May 2012.

The research focuses on the construction industry and the waste generated therein. Particular attention is being paid to gypsum wallboard, which comprises 25% of construction and demolition weight volume in landfills. Gypsum products have already been banned from major metropolitan landfills across Canada and steps have been taken within industry to help deal with this 100% recyclable product. The successes and failures of these initiatives will be investigated to shed light on how lessons can be learned and applied to the reduction of other construction and demolition waste products.

Ryerson University Department of Architectural Science, Faculty of Architectural Science also, prepared an ‘Annoted bibliography of waste minimization, recycling and reuse issues in the construction industry. This document provides a list of relevant publications, focusing on North American documents addressing various aspects of material resource use and disposal in construction, now posted in the ‘WHAT TO DO>LIBRARY’ portion of the CRI Council web site

GUELPH UNIVERSITY Environmental Engineering Dr. Brajesh Dubey has also recently stepped forward to support the Mission 2030 initiative, and will be leading an important research on recycling drywall in the agricultural sector, in collaboration with other researchers such as the Nova scotia Resource Recovery Fund Board, also engaged collaborators of the CRI Council.   See the attached for more info on this   


  • Wood Recycling
  • Cement/Aggregate Recycling

MOVING FORWARD:   the objectives of the R&T discussions will principally be to identify the key research priorities related to construction material resource use for the CRI Council; and how these should be addressed.

This group presents an opportunity to discuss which areas, or research, and further development of information would be most useful to the industry. How can university researchers help, industry meet the objective of Mission 2030? For example, would more detailed energy audits be useful and how can we organize such activity?

This group will also address the relevance of issues such as EPDs, as a way to address waste in construction products; or review and endorse research and reports by others.

The Research & Technology committee will work closely with industry subject matter experts, CRI Council supporter organizations, and other council partner universities, will be an important industry representative, helping create links, and focus. This will be extremely important for industry support, increasing matching public funds. The CRI Council is proud to be working with the following individuals, in the quest for zero waste.

DR. MARK GORGOLEWSKI B.Sc., M.Sc., Ph.D., DIP ARCH, LEED AP.:    Dr Mark Gorgolewski is a Professor and Program Director for the graduate program in building science in the Department of Architectural Science at Ryerson University. He is a Director of the Canada Green Building Council and has worked for many years as an architect, researcher and environmental consultant to the construction industry in Canada and Europe. He has published many books, articles and papers on issues of the sustainable built environment.

Dr. BRAJESH DUBEY, P. ENG; teaches and does research in the area of Environmental Engineering Sciences and Health at University of Guelph, Ontario.  Dr. Dubey has received his PhD in Environmental Engineering Sciences from University of Florida.  He has also worked as a Consulting Environmental Engineer for 4 years. His research interest includes Integrated Solid and Hazardous Waste Management, Environmental Risk and Exposure Assessment: Fate, Transport and Biological Availability of Emerging Contaminants in different Environmental Systems and Sustainable Environmental Technologies.  Dr. Dubey has authored/co-authored more than 120 publications in his area of expertise and has presented at several national and international conferences and has assisted United Nations and World Bank as a specialist in environmental projects in emerging/developing countries.

JOSEPH EARLE has a Bachelor of Humanities from Carleton University and is an apprentice Carpenter with Local 397. He is currently a graduate student in the Building Science program at Ryerson University in Toronto. He is conducting research under the supervision of Jane Hao and Mark Gorgolewski on the topic of construction, renovation, and demolition waste with a particular focus on residential renovation waste and the markets for reused and recycled building materials.
