Résumé :
The general objective of this research is to develop a user-friendly decision-support software tool that allows setting up optimal organic waste (municipal wastewater treatment plant sludge and the source-sorted organic fraction of municipal solid waste (SS-OFMSW), notably) valorization chains for the Québec province. A holistic modelling approach will be applied, focusing on cost and greenhouse gas (GHG) emission minimization throughout the whole value chain, including organic waste generation/ collection, waste treatment and end-product distribution, thereby taking into account legislative and social constraints. The software tool will integrate three key components: 1) a multidimensional spatiotemporal database system (including georeferenced and non-georeferenced data), 2) a model-based decision module (for simulation and optimization), and 3) a user-friendly interface (to facilitate knowledge transfer and interpretation). The developed tool will be validated in a case study for the Québec City Agglomeration and its surrounding rural environment. The availability of such tool will allow Québec municipalities and industry to optimally plan the location, capacity and treatment scenario of their waste flows, as well as the distribution of the resulting end-products at minimum cost and environmental footprint, taking into account potential public nuisance and environmental regulations in force. As such, this project clearly addresses the three pillars of sustainable development: environment, society and economy. Moreover, the project will facilitate the achievement of the objectives of the Québec Residual Materials Management Policy (i.e. the banning of organic waste incineration/disposal from 2022 onwards [1]), which is an important part of the Québec action plan on climate change. The industrial partners, Primodal Inc. and Chamard et Associés Inc. (Chamard-Env), will directly benefit from using the developed tool in their contracts with industry and municipalities, where the demand for a decision-support framework for biomass valorization is high due to the waste regulation in force. Moreover, the industrial partners will be able to extend their markets and services due to the developed knowledge and tool. The methodology developed in this research may also be extended and used for engineering and consultancy services in other Canadian provinces, as well as abroad. Université Laval (as well as other universities and research institutions) will benefit from the availability of this tool since it will allow defining sustainable organic waste valorization paths and identifying promising new strategies, requiring further research and development. The tool, knowledge and publications resulting from this work will hence be of high relevance to the natural science and engineering community, so will be the highly qualified personnel (HQP) trained in this project.
