Canada has a large pulp and paper industry and it produces tons of waste in the form of wastewater and greenhouse gas emissions. Collectively the industry spends hundreds of millions of dollars to lower their environmental damage, so even a marginal increase in environmental efficiency can have a large impact on their bottom line.
A study from Concordia University looked into using dynamic systems modelling to asses what the output of processing facilities to predict waste output.
â€œWith dynamic modeling, we can better understand the behaviour of the treatment plant over time,â€ says senior author Fariborz Haghighat, professor in Concordiaâ€™s Department of Building, Civil and Environmental Engineering and Concordia ResearchChair in Energy and Environment. â€œWith this knowledge, we can then recommend a strategy to reduce the emission of greenhouse gas and also improve energy efficiency.â€
â€œModels such as this are used to simulate the behaviour of a particular management system either in the early stages of system design or in later development to incorporate changes,â€ adds Yerushalmi. â€œWe want to make sure that we use the most accurate method possible and the dynamic model isbest predictor yet.â€
