‘I don’t trust supermarket food’: Supporting Sustainable Urban Agriculture in Asia
Sarah Turner (Department of Geography), Hien Pham (Département d'études urbaines et touristiques, UQAM), & Melody Lynch (PhD candidate)
Increasing food production in cities and practicing environmental-friendly food production can substantially reduce the ecological and carbon footprints of cities, working towards global sustainability. Cities import food and produce waste that is seldom recycled or reused, and while 55% of people live in cities, cities create 60% of global carbon emissions. This project explores the attempts of local residents in Vietnam and Indonesia to build alternative food provisioning approaches in small cities through urban agriculture. The focus is on small cities as they are set to become the dominant urban form in the Global South in the near future.
High risk/high reward projects are increasingly seen as avenues to move fields of research forward rapidly. The MSSI Ideas Fund provides small amounts of seed funding to explore bold projects and novel ideas which, if successful, could make a significant impact on a sustainability-related challenge.
The Fund allows recipients to explore the feasibility of ideas before dedicating significant resources to flesh them out. This includes development of collaborations and production of data required to justify a multi-disciplinary grant application in the area of sustainability. Its aim is to enable development of projects to a stage where they can attract other funding, perhaps in one of our thematic research areas.
3D printing of Architected Ferroelectrics for Sustainable Energy Harvesting
Hamid Akbarzadeh & Agus Sasmito
In efforts to reduce our dependency on fossil fuels and to lessen their environmental impacts, a new sustainable energy material based on architected ferroelectrics will be designed and 3D printed to simultaneously scavenge energy from wasted resources and to strategically reduce energy consumption in structural systems and infrastructure.
Ultrahigh-efficient solar desalination via novel hydrogels spontaneously lowering enthalpy of vaporization
Jinxia Liu, Jianyu Li & Mélanie Tetreault-Friend
Solar desalination is an effective solution to address water scarcity, but the high energy demand to evaporate water poses a technological barrier. We aim to develop novel light-sorbing hydrogels that can spontaneously lower the energy demand, owing to the unique ability to disrupt forces holding water molecules together. A prototype solar still equipped with the hydrogel will be tested for efficiency benchmarking and water quality.
The effect of microplastics on cloud droplet formation
Thomas Preston & Alison Bain
The elimination of single-use plastics is at the heart of many sustainability initiatives. Understanding the lifecycle and impact of these materials on atmospheric processes will be crucial in the design of their alternatives and key to avoiding an outcome where a replacement is unintentionally more harmful to the environment. Using optical trapping, we will be able to study water uptake and loss in small droplets that contain microplastics. These high-precision measurements will allow us to begin to understand the role of microplastics in cloud droplet growth and the subsequent implications for transport in the atmosphere and climate change.
Ultrathin and ultrastrong alternatives for plastic films
Theo van de Ven & Jean-Philip Lumb
This project is developing a proof of concept that biorenewable, biodegradable, recyclable and water-insoluble ultrathin and ultrastrong transparent films can be made from cellulose using continuous flow casting from dilute solutions. This opens the door to sustainable plastic alternatives, thus tremendously reducing plastic waste.
All-plant-derived biodegradable packaging with mechano-bactericidal activity
Yixiang Wang & Jennifer Ronholm
The release of organic preservatives and inorganic nanoparticles incorporated into antimicrobial packaging materials presents a risk to consumers. At the same time, petroleum-based food packaging, like any other short-term storage packaging materials, represents a serious sustainability challenge. This project is developing a mechano-bactericidal, biodegradable material from natural polymers that is suitable for food storage.
GLAD – the Global Lake Analysis Dashboard
Jeffrey Cardille & Bernhard Lehner
This project will build the Global Lakes Analysis Dashboard (GLAD), a novel toolbox for both the general public and scientists to learn about lakes. GLAD will be a public repository of lake information, including satellite imagery, delineated lake perimeters, calculated area, estimated depth, and more. Running in Earth Engine, GLAD will provide the ability to graph time series, compute similarities between far-flung lakes, and find regional patterns.
Coupling microbial metabolism and biogeochemistry to identify mechanisms that mitigate positive feedback effects of thawing permafrost peatlands to climate change
Cynthia Kallenbach & Peter Douglas
Permafrost peatland soils store vast quantities of carbon. As it thaws under a warming climate, soil microbial communities could release much of this carbon as greenhouse gases into the atmosphere, creating a runaway feedback effect on warming. Combining molecular chemistry, genomics, and isotopic geochemistry, we will determine the microbial controls regulating if and when positive versus negative feedback effects to climate change occur.
Global contaminant fate model and data development to screen for chemicals in rivers and lakes
Bernhard Lehner & Jim Nicell
To protect our surface water ecosystems and to sustain their benefits to society, including the provision of safe drinking water, we need to understand the sources and distribution of potentially harmful substances in the river and lake network. This project aims to develop a contaminant fate model and associated data, in particular information about wastewater treatment plants, to screen for the concentrations of contaminants in the aquatic environment at large scales, including down-the-drain household chemicals, pharmaceuticals, microplastics, and nanoparticles.
Fabrication of Nanoporous Membranes for Blue Energy Harvesting
Walter Reisner & Peter Grutter
One attractive source of renewable energy, known as “blue” or osmotic energy, uses the salinity difference between ocean and fresh water to generate power. A major impediment to exploiting blue energy is the poor efficiency of commercially available membranes for blue energy conversion. Nanoscale membranes with pores at or below 5 nm in diameter may provide sufficient power generation to make blue energy viable, yet, currently no technology exists that can produce such membranes with sufficient control and scale. Here, leveraging a new approach developed at McGill for fabrication of nanopore arrays, "Tip-Controlled Local Breakdown," we will produce nanoporous membranes for blue energy conversion with sufficient control of pore size and spacing to optimize membrane efficiency.
Mining the Chicken Microbiome for Anti-Infective Probiotics to Eliminate the Need for Prophylactic Antibiotics
Current high-density models of poultry production are not sustainable without the use of antibiotics, but due to antibiotic resistance agricultural use of antibiotics is becoming less accepted. This project aims to investigate the avian gastrointestinal tract as a source of novel probiotic bacteria, particularly within the Proteobacteria phyla, that have a negative effect on the ability of bacterial pathogens to colonize commercial poultry. The discovery of anti-infective probiotics could decrease reliance on prophylactic antibiotics and improve sustainability within the poultry industry.
Combined CO2 Reduction and Biomass Upgrading System for Sustainable Production of Fuels
Electrochemical CO2 reduction reaction (CO2RR) and biomass upgrading hold promise for CO2-mitigation and green fuel production. However, CO2RR suffers from high applied potential, and the biomass upgrading process emits significant amount of greenhouse gases - hindering their employment. Here, we combine these processes within a single electrochemical system to not only reduce the applied potential, but also to produce green chemicals and feedstocks with zero CO2 emission.
Seasonal energy storage through means of phase change of water contained in soil
Matthew Fong & Agus Sasmito (faculty supervisor)
Seasonal energy storage through means of phase change of water contained in soil: There is a growing need to incorporate renewables into our energy consumption budget. A lot of work has been done in including renewables into the electrical grid, however another way to do so is through heating and cooling. Directly incorporating renewables into heating and cooling systems allows for relatively easy and high impact reduction in emissions. This project seeks to use the cold from winter to cool during the summer and the heat from summer to warm during winter.

Designing High Performance Photocatalytic Semiconductor Junctions for Solar Fuel Production
Asif Iqbal & Kirk Bevan (faculty supervisor)
This project aims at unraveling the in-operando charge transport process at a photocatalytic semiconductor-aqueous junction. Our scientific approach connects numerical computation with the experimental results to explore critical processes occurring at fast and slow timescales. A comprehensive study of this nature promises to open up new avenues to engineer the in-operando performance of photocatalytic semiconductor junctions en route to improved solar hydrogen production.
Designing fully degradable alternatives to single-use plastics by upcycling food waste
Nicholas Lin, Sunny Weng & Nathalie Tufenkji (faculty supervisor)
Most single-use plastics are not recycled. Instead, they accumulate in landfills for centuries. Many by-products from the food industry are degradable, biorenewable, nontoxic, and edible. Fruit peels, vegetable husks, and other food waste will be blended with natural biopolymers such as starches, gums, and seaweed extracts to design fully degradable products that can replace single-use plastics.
A new strategy to screen antagonistic bacteria against Staphylococcus aureus for sustainable therapeutics and medical interventions
Soyoun Park & Jennifer Ronholm (faculty supervisor)
This project aims to design and develop a new strategy to screen antagonistic bacteria against S. aureus which causes a broad range of diseases in livestock including bovine mastitis. Antagonistic bacteria has been suggested as one of the promising alternatives to antibiotics to maintain the sustainability of agriculture since antibiotics are being phased out of usage in Canadian agriculture. To find bacteria that are antagonistic to S. aureus among commensal bacteria, a more effective and efficient screening strategy needs to be developed. A new plasmid ‘pQS2’ will allow us to label S. aureus with fluorescent proteins and co-culture S. aureus with commensal bacteria to monitor its growth and quorum sensing activity.
“Green” antimicrobial straws - an alternative to synthetic plastic straws
Paola Sully, Camila Oliva, Shuting Huang, Yi Zhang, Benjamin Simpson (faculty supervisor) & Yixiang Wang (faculty supervisor)
We use “green” technology to produce composite straws from marine and agricultural waste that exhibit outstanding antimicrobial and mechanical properties. The generation of “green” antimicrobial straws is a sustainable approach to reducing the use of single use plastics by being compostable, biodegradable and nontoxic to the environment. Our goal is to propose an alternative solution to synthetic plastic pollution.
A compact, ready-made methane monitoring station powered by leaking oil and gas infrastructure
James William & Mary Kang (faculty supervisor)
Fugitive methane emissions from the oil and gas sector represent a significant portion of the greenhouse gas budget in North America, but are still poorly understood in terms of their temporal emission patterns. A necessary step to improve our knowledge of temporal trends in emissions is long-term and continuous monitoring, which requires a power source that can sustain a measurement system. By harnessing fugitive natural gas emissions as a fuel source, our monitoring station will simultaneously reduce the greenhouse gas footprint of a leaking well, and gather long-term temporal data regarding emission patterns. Our project also has potential applications in other fields of methane emission monitoring, such as arctic regions where popular off-grid power sources (e.g. solar panels) are limited in their power generation capabilities.
Transformation of Soluble Phosphate, a Pollutant within Manure, to an Insoluble, More Sustainable Calcium Phosphate Solid with Waste Concrete
Tian Zhao & Sidney Omelon (faculty supervisor)
Phosphorus fertilization is essential for agriculture; however, the primary resource for making phosphorus fertilizer, phosphate rock, is non-renewable and depleting. Therefore, the goal of the project is to stabilize the phosphate in cattle manure and convert it into feasible phosphorus fertilizer, as a calcium phosphate crystal. Manure has a long history as a fertilizer, but excessive soluble phosphate in manure is environmentally problematic. The project can help offset the depletion of phosphate rock and ensure food security, as well as reduce soluble phosphate and avoid eutrophication.

Development of an electrocatalytic method for the direct functionalization of methane to aldehydes
Alkanes, and alkyl-containing compounds are perhaps the most common resource available for the generation of synthetic materials. As a result, the design of a method that allows the conversion of these feedstocks directly into easily manipulated products has become one of the central goals of chemical research, and would offer a significant step forward in their sustainable use. The proposed work is directed towards creating a new method to functionalize hydrocarbons such as methane: via their catalytic coupling with carbon monoxide. This would offer not only a new method to exploit alkanes in chemical synthesis, but also a potential avenue for the utilization of methane as a chemical and energy resource.

Supercritical metal-water reactor proof of concept
Convenient access to clean and reliable energy sources is key to transitioning away from fossil fuels. This research focuses on using metal-water reactions to provide clean energy on demand. Metal fuels can be processed using renewable energy, such as wind and solar, thereby effectively storing and allowing for the transport of clean energy. The clean energy stored in the metal electrofuels can then be released via metal-water reactions to produce heat and hydrogen for use in a wide range of transportation and stationary power-generation applications.

Changing-climate resilient cisgenic crop variety development through genome editing
Kushalappa lab at McGill has identified several disease resistance R genes. Some of these genes are mutated in commercial wheat cultivars, such as Pasteur, which will be replaced with functional gene segments from a resistant wheat land race based on genome editing using CRISPR-Cas9 system that does not leave any foreign DNA in the recipient plant. Following proof of concept, this technology can be used to enhance multiple disease resistance in hundreds of wheat and other crop cultivars, saving billions of dollars around the world.

Using air and solar energy as a sustainable source of water
Kevin Kelly, David Villegas, Jan Kopyscinski (faculty supervisor)
Presently, water scarcity affects every continent. In 10 years, more than two-thirds of the world's population could be living under water stressed conditions. However, a significant amount of water resides in our atmosphere, a resource that if made available, would help solve the problem of water scarcity. Taking on this challenge, we have come up with an idea to extract humidity from air using low grade thermal energy (e.g., solar heat), and create water through a novel process.

Jan Kopyscinski & Annie Levasseur (École de technologie supérieure, Université du Québec)
The Power-to-Gas (P2G) process is a promising technology in which renewable electricity is converted into chemical energy (methane) and stored in the natural gas grid. The main challenges are the catalytic conversion of H2 and captured CO2 into CH4. This project will build prototype reactors (catalytic heat exchanger design with alternate reactive and non-reactive channels) and evaluate their performance in terms of CO2 conversion, long-term stability as well as conduct a techno-economic and life-cycle-analysis. Goal: Canada’s first P2G process!
Deconstructing to Reconstruct – A Sustainable Valorization of Lignin to Pharmaceuticals
To maximize value from biomass, the value of lignin must be increased. Since more than 90% of current pharmaceuticals are produced from petroleum, large growth opportunities for lignin-derived building blocks exist in this sector. This research aims to capitalize upon recent advances in lignin depolymerization technologies to create a value chain that affords the chemotherapeutic podophyllotoxin. By valorizing lignin into pharmaceuticals, we hope to create an economic incentive for increased biomass utilization, and motivate additional engagement from pharmaceutical companies interested in developing sustainable manufacturing practices from renewable feedstocks.
Assessing the environmental impact of urban micro-mobility services
The influx of micromobility services, such as dockless scooter-share and e-bikes, in many cities are contributing to a substantial change in urban transportation. The rapid arrival of these services, however, has left little time for city regulators and citizens to assess the environmental impact of these services and compare them to existing transportation options. In this project we will develop and widely disseminate a survey to both users and non-users of micromobility services across Canada. Given the results of this survey, and vehicle emission data, we will calculate the actual environmental (GHG) impact of these new services on urban centres across Canada.

Novel plasma technology for renewable ammonia synthesis
Ammonia (NH3) is one of the most important chemicals produced today. It is produced at large scale using the energy-intensive Haber-Bosch (H-B) process, and used in the synthesis of fertilizers and virtually all synthetic nitrogen-containing chemicals. The annual production of NH3 is larger than 160 million tons, with associated CO2 emissions exceeding 300 million tons, and energy requirements accounting for ~2% of the world’s energy consumption. The proposed plasma technology bears the potential to displace the energy-intensive and polluting H-B process by using electricity from renewables as the only energy source.
Sustainable Green Plasticizers
Richard Leask, Milan Maric & Jim Nicell
Plasticizers are added to the majority of consumer plastics to improve their flexibility and processing behavior. During the last decade, the most common plasticizers, known as phthalates and which are produced in the millions of tons annually, have been shown to have adverse health effects. Moreover, they are made from fossil fuels and are ubiquitous environmental contaminants. In this work, we will be performing large scale production run of our replacement sustainable green plasticizer as a validation towards commercialization.

Closing the Phosphorus Loop through Phosphate Rock Production from Municipal Sludge
Municipal wastewater contains high concentrations of phosphorus (P) that must be reduced to prevent algal blooms and eutrophication. Current wastewater treatment precipitates insoluble iron phosphate, which is too stable to act as a P-fertilizer. This project investigates P-capture as phosphate rock to produce P-fertilizer from municipal wastewater, CO2, and limestone.
