- Centralized sorting stations and removal of individual bins at CAE's headquarters

CAE's head office is located in Ville Saint-Laurent; it is a multi-use, one million square feet building that houses an assembly plant, engineering and support offices, as well as simulator test sites and two tenants. Nearly 4,000 people work there every day (permanent employees, contractors and customers) and generate waste. In 2015, the building management department decided to set up centralized waste stations instead of 8000 individual bins, these stations introducing sorting of compostable materials. This conference is the story of all stages of this implementation; from the pilot project launched in June 2016 to full deployment throughout the building in the years 2017-2018, including all the social acceptability issues of the project encountered in all communities of CAE.

- Estimating the global cost of waste disposal in a business using Material flow cost accounting

When evaluating the profitability of waste diversion measures, business managers mostly look at the garbage collection cost and underestimate the indirect costs associated with material inefficiencies. A Material flow cost accounting analysis (MFCA), described in the ISO 14 051 norm, allows to calculate the global cost of waste. The analysis take in consideration the disposal cost and impute other indirect costs attributed to material inefficiencies. A MFCA analysis also allows to calculate the completed cost reductions if the business changes its processes. While this approach is common in other countries, it is rarely used in Québec. The Centre de Transfert technologique en Écologie Industrielle is currently adapting the methodology proposed by the norm so that it may be used by waste management experts. The conference will present an application case of a MFCA analysis in a business.

- Feeding roofs with hospital kitchen waste : an innovative synergy

This synergistic adventure begins with Martin Marion from LiveRoof Québec, a visionary entrepreneur from the Lanaudière region, who has set himself the goal of developing a Green roof substrate made of 100% locally recycled materials from circular economy. At the same time, concerned about is environmental impact, the Lanaudière Hospital Center is starting a process to improve its residual materials management. The hospital opts for "in situ" dehydration of its organic materials ( preparation of some 2157 daily meals and food remains ). A technology still unknown in Québec, the dehydrated organic residues are then in part integrated into the substrate of green roof. The project had to deal with a wide range of technical, regulatory and economic validation. With this initiative the hospital diverts 150 tons/year of organic material from landfills and significantly reduces its climate impact.
