Laboratories – Université Laval

Virtual tour of the Kruger Pavilion, Université Laval

The majority of the Renewable Materials Research Centre (CRMR) laboratories at Laval University are located in the Gene-H.-Kruger building. This eco-friendly building, equipped with a bioclimatic environmental control system, is constructed almost entirely of wood and using local products was encouraged to benefit the regional economy and minimize pollution and transportation costs. In addition to conference rooms, classrooms and offices, there are ten workshops and eight laboratories where teaching and research are carried out in a number of fields including wood anatomy and physics, primary and secondary transformation, composite panels and polymer and adhesives chemistry. Futhermore, work on the implementation, characterization, modification and modeling of natural fibre-based composites, including expanded materials (foams), multilayer structures (sandwich) and recycling, under the supervision of Denis Rodrigue are carried out in the laboratories of the Chemical Engineering Department in the Adrien-Pouliot Building.

Overview of services

The CRMR is committed to exploring the potential of sustainable materials and offers a full range of external services to a diverse client base. These services encompass a wide range of activities and expertise, responding to the specific needs of academic researchers and various organisations (public and private) and industries seeking to promote research, development and innovation. Based on advanced research and innovative approaches, the centre offers valuable assistance in areas such as: the characterisation of raw materials, biopolymers and materials; the development of products, innovative systems and eco-responsible buildings; and the assessment of the behaviour, fire and environmental performance of innovative products and systems. In addition, the centre’s team of leading experts and researchers promotes innovation and collaboration, stimulating excellence and scientific and technological progress.
