Air pollutant emissions from the oil sands and impact on the local First Nations community: Fort McKay
Faculty advisor: Professor Jeffrey Brook
The Canada-Alberta Oil Sands Monitoring Program (OSM) operates a heavily instrumented atmospheric monitoring site in Fort McKay, a First Nations community surrounded by the oil sands development. Many pollutants are being measured with high time resolution, including some measures in the vertical and space-based measurements from satellites. Hydrocarbons, nitrogen oxides, fine particulate matter, dust and odours are notably critical air quality issues. A large, publicly-available dataset is available which represents an important opportunity to improve understanding of how the oil sands is impacting the community, its people and its environment, and to apply a range of data analysis techniques.
Research projects of interest will harness novel data mining techniques to learn more about what aspects of the oil sands activities are responsible, when and why they occur (e.g., meteorology) and potentially which industries are responsible.

Analysis of liquid and solid samples from a pulp and paper mill
Looking for an MEng student to analyze liquid and solid samples from a pulp and paper mill, specifically focusing on wood extractives and sulfur compounds. The aim of this project is to uncover the underlying processes behind the formation of organic deposits within the black liquor evaporation system at a collaborating pulp and paper mill in New Brunswick. These deposits have consistently posed a challenge across multiple mills, leading to significant equipment downtime and revenue loss.
The chosen student will have the opportunity to visit the mill and gain insight into the operational procedures and machinery. Cutting-edge analysis techniques, such as Pyrolysis-GC/MS, LC/MS, ICP, and/or MALDI-TOF-MS, will be employed for the investigation. Analyses will be implemented by the student within our labs, or by other UofT labs. Furthermore, the student will be tasked with integrating the outcomes from all analyses into a cohesive understanding.
Knowledge about organic chemistry and experience with any of the aforementioned techniques is an asset but not a requirement. The ideal MEng candidate is meticulous and committed to producing repeatable and publishable data.
The project duration is flexible, but an immediate start date is preferred.

Enzyme discovery and development for the functionalization of industrial lignins
Faculty advisors: Professor Elizabeth Edwards, and Professor Emma Master
The broad objective of this project is to discover and develop novel biocatalysts or enzymes to upgrade and functionalize intact biomass components, specifically, under-utilized industrial (or technical) lignin sources. The enzymes under study will be derived from fungal and bacterial species that are known to be naturally active on diverse lignin sources and will be biochemically characterized. These will include oxidoreductases (laccases, peroxidases) and novel o-demethylases (catalyzing phenyl-methyl ether demethylation) from anaerobic environmental metagenomic sources. This study targets modifications that increase the hydroxyl content in lignin so that it can be effectively used as a substitute for fossil-fuel derived phenol polymeric blends.
We are seeking an M.Eng student to help with the anaerobic enzyme discovery module of the project. The purpose of this module is to discover novel enzymes from anaerobic microbial cultures that have been maintained in-house for several years on lignocellulosic biomass and have a unique repertoire of enzymes that would be especially useful for lignin modification and valorization. There will be a multi-step screening approach taken towards enzyme discovery using firstly, biochemical methane potential assay and next, specific chemical assays for o-demethylation activity.
In this module, there will be opportunities to train on the maintenance and analysis of the biodegradability potential of these cultures when grown on different, industrially important, lignin substrates. Specific tasks will involve biogas measurements, biogas composition analysis using gas chromatography and acetate measurement using ion chromatography. Next, protein extraction will be done from promising cultures demonstrating lignin biodegradability. Finally the trainee will assist in the development of high-throughput, robust chemical assay aimed at testing crude and purified protein extracts for o-demethylating activities.
The project duration is flexible, but an immediate start date is preferred. The student will be supported by other students working on the project.

Improving performance of a solar-battery powered remote air quality monitoring site
Faculty advisor: Professor Jeffrey Brook
In the oil sands region the pollutant emissions spread far beyond the fencelines and impact remote areas. Monitoring in these areas is difficult because no power is available. The Fort McKay First Nations community has developed a solar-battery powered system to address this challenge, but due to limited solar energy and extreme cold in winter months the system experiences downtime.
This design project will involve exploring ways to insulate the batteries to increase their lifetime to reduce or eliminate downtime. Other ideas to improve solar energy input or harness wind energy could also be explored in order to assist Fort McKay in their monitoring.

Investigation of Pichia Pastoris strains for the successful production and characterization of Auxiliary Activity family 7 enzymes (AA7s)
Auxiliary activity enzymes are oxidoreductases that catalyze the oxidation of carbohydrates (and other compounds) through the action of a Flavin adenine dinucleotide (FAD) co-factor. They are crucial players in the goal to valorize oligosaccharides derived from biomass processing and for building novel functional biopolymers. Pichia Pastoris is a popular expression system for protein production, with relatively cheap growth medium and a high growth rate, compatibility with shake flasks and large-scale bioreactors, and comparatively easy genetic manipulation for heterologous expression.
The prospective M.Eng student would be directly involved in the genetic manipulation phase of the project. This phase involves producing gene constructs for multiple AA7 targets, transformation into multiple strains of P. pastoris, and the validation of protein expression levels. This phase of the project is truly the heart and would directly lead to the successes of the downstream activity screens and biochemical characterization.
The prospective M.Eng student would work closely with a Post-doctoral fellow and other graduate students, which would provide numerous training opportunities in biochemistry and molecular biology. In this increasingly biotech world, genetic engineering, protein production, and protein biochemical characterization are valuable experience to have for a highly competitive job market. Tasks that the student can expect to perform include PCR amplification of genes, insertion of genes into vector constructs, validation of plasmid integrity via RT-PCR and gel electrophoresis, transformation of plasmids into P. pastoris strains, and validation of positive clones via colony and western blotting. Along with these tasks, training on various related instruments should also be expected.
The project timeline has an expected start date in Summer 2021, but a flexible start date could also be accomodated.

Obtaining informative data of water contamination in the Thunder Bay area relative to known acute myeloid leukemia clusters
Fort William First Nation (FWFN) has identified a striking blood cancer cluster. The prevalence of acute myeloid leukemia (AML) in teens and young adults is noticeable, many of whom spent their early childhood living adjacent to lands used for industrial purposes. FWFN would like to know what is causing the high rates of AML in their community and if it is safe to live, work and raise a family in their current location. The area of concern (AOC) is a community located at the northern vertex of Lake Superior and close to the mouth of Kaministiquia River to Lake Superior. This AOC has been affected by a leachate plume from a bark dump migrating towards City Road and other point sources of contamination, with engineering reports confirming the presence of high levels of pollutants at monitoring wells.
This project aims (i) to obtain informative data from existing water quality assessments and analytical reports of surface and groundwater sources; (ii) to identify and link sources of chemical pollutants to the movement of pollutants through systems. These objectives will be achieved by (i) integrating and mapping combined multilayered information using non-supervised machine learning tools; (ii) discriminating and ranking different polluting sources affecting the AOC using multivariable statistical analysis such as Principal Component Analysis (PCA); and by (iii) unravelling the possible relationship between ground (soil and groundwater) contamination and air emissions, using supervised machine learning tools.
The results derived from this analysis will likely yield insight into the influence of specific contaminants on health, and hence, the leukemia cluster.
This project is in collaboration with ATOMS Lab and the Centre for Indigenous People.
Requirements: Knowledge in data analytics and machine learning (in MATLAB, R, Python, or equivalent).

Plastic waste and biowaste pyrolysis
Faculty advisors: Professor Donald Kirk
The world is facing a number of challenges in the sustainable energy field. Managing GHG emissions as well as wastes are often at odds. A belated realization that plastics do not degrade easily has added to the waste challenges. It is clear that some form of permanent sequestration of carbon is needed to rebalance CO2 emissions with CO2 bioabsorption. The research is focused on conversion of wastes containing sufficient carbon content to produce sequestrable char as a valuable soil amendment and eliminate the production of CO2 and CH4. Biowastes such as sewage sludge, have a limited lifespan in soil or landfills and hence returns to the carbon cycle. Non-recyclable plastics have a longer degradation time but it is clear that degradation producing micro and nano particulates causes global contamination with uncertain consequences. Therefore the conversion of these wastes to char which can be used to enhance crop growth, prevent fertilizer runoff, retain moisture and provide micronutrients for restoring degraded lands is desperately needed.
The research on conversion of some biowastes to char has been completed and demonstrated on a commercial scale in Ontario. More biowastes still need to be studied. Research on conversion of plastic wastes has just been started.

Projects in Food Engineering
Faculty advisors: Professor Levente Diosady and Dr. Juveria Siddiqui
The Food Engineering Research Group at the Department of Chemical Engineering and Applied Chemistry performs research on food fortification technologies. Double Fortified Salt (DFS) technology of adding iron and iodine to salt was developed at the Food Engineering Lab, UofT. This Double Fortified Salt aims to reduce anemia which is a major contributing factor to the 200,000 annual maternal deaths and more than one million annual infant and neonatal deaths globally. DFS technology is now pilot tested in India and is reaching more than 60 million people.
The following opportunities are for MEng students:
Iron Fortification: Approximately 2 billion people are iron deficient worldwide. This is best addressed through food fortification, which is transparent to the consumer. Fortification requires a carrier that is universally and uniformly consumed by the target population. For poor rural consumers in South Asia salt and tea are the most promising carriers. Unfortunately, both salt and iron salts are reactive, and the technical challenge is to maintain the bioactivity of the added micronutrients.
This project seeks to develop appropriate technology for adding iron and other micronutrients to either tea or salt.
Mustard Protein Processing: Mustard is a drought tolerant Canadian crop now used for condiments. Its protein content is well balanced and could be a useful food ingredient replacing soy proteins in manufactured food products. The oil is not allowed in food in Canada, but is a potential fuel feedstock.
This project seeks to further develop processes to simultaneously recover food proteins and biodiesel or green diesel from mustard seed.
Work Load: Both projects entail laboratory work in 5-6 hour experiments for 5-6 months.

The case for Blue Hydrogen: A carbon footprint study
Summary: Canada is a global leader in producing blue hydrogen, which is described as having low greenhouse gas emissions (GHG). Alternatively, some climate assessments claim that blue hydrogen is 20% worse for GHG emissions than natural gas for heat. Several methodologies have been proposed to assess the life cycle of blue hydrogen with no consensus on GHG emissions. This 4th Year’s student thesis aims to compile and compare existing life cycle analyses (LCA), formulating solid assumptions and setting the basis to close the LCA gaps, and making a sound conclusion on the impact of blue hydrogen on climate. Chemical engineer students are equipped with the knowledge to elaborate a carbon footprint study by performing material and energy balances around blue hydrogen processes using process simulation software and estimating CAPEX and OPEX.
