Reference number : GC-2017-Q4-00354, amendment number : , agreement type : G, recipient legal name : Christopher, Lew (Lakehead University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Plus Grants for universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : The Canadian pulp and paper industry generates about 1.5 million tons of primary and secondary sludge every_x000D_
year, which requires disposal and presents a major environmental challenge. On average, 60% of the total_x000D_
wastewater treatment costs of pulp and paper mills account for sludge disposal. For this reason, Domtar Inc., a_x000D_
global pulp and paper company, is interested in minimizing their waste sludge and converting it into a_x000D_
value-added stream that can reduce the carbon footprint, diversify their product range, create additional_x000D_
revenues, and enhance their competitiveness on the international market. For example, the Domtar Windsor_x000D_
mill, with annual pulp and paper production capacity of 447,000 and 642,000 tons, respectively, generates 75_x000D_
tons of sludge per day. The mill disposes of their waste sludge by landfilling, a process that is neither_x000D_
economically attractive nor environmentally friendly. This is a follow-up Engage Plus proposal that aims to_x000D_
further advance the positive outcomes from the original Engage project. The Engage Plus proposal will further_x000D_
investigate opportunities to valorize the mill sludge from Domtar through a novel recycling process that could_x000D_
increase the efficiency of the proposed enzymatic hydrolysis and fermentation process, and reduce the overall_x000D_
production costs. Domtar mills will directly benefit from the outcomes of this project by upgrading a waste_x000D_
sludge stream to value-added products such as sugars and lactic acid. The Engage Plus project will address_x000D_
important milestones such as optimization of enzyme and surfactant dose, enzyme and substrate recycling,_x000D_
fermentation of primary sludge-derived sugars utilizing low nitrogen sources such as secondary sludge, process_x000D_
integration and optimization. The following steps are essential to accomplish the project goals: 1)_x000D_
Compositional analysis of sludge; 2) Analysis of enzyme activity/loss conversion yields; 3) Optimization of_x000D_
enzyme dose for maximal release of fermentable sugars; 4) Protein solubilization from secondary sludge and_x000D_
protein characterization; 5) Bioconversion of primary sludge-derived fermentable sugars using solubilized_x000D_
protein from secondary sludge as nitrogen source., program purpose french : The Canadian pulp and paper industry generates about 1.5 million tons of primary and secondary sludge every_x000D_
