Exploratory study: modification of sludge based sorbents for nutrient removal from stormwater runoff

Nutrients (P, N) in stormwater runoff are a major cause for eutrophication and algae blooms. Kerr Wood Leidal (KWL) is a leader in proving progressive solutions for stormwater management in BC, is seeking to improve the rain garden system to effectively capture the nutrients in the runoff. The proposed project will investigate various chemical activation to produce effective biomass-/sludge-based sorbent.

Kinetics of dispersion of fine phosphate particles associated with organic matter

This research project seeks to improve the process which is used to recover fine phosphorous particles from mine tailings. Phosphorus based fertilizers are important for plant growth and essential to large-scale, high-efficiency farming methods. However, the processing method used to obtain phosphate from phosphate-bearing ore is not very efficient. Upward of 13 % of the available phosphate is lost to the waste stream during processing, which represents a major inefficiency and creates a large environmental problem.

Social and informational strategies for reducing electricity and natural gas consumption in multi-unit residential buildings

The proposed research will attempt to help residents reduce energy use in apartment buildings. The intern will provide residents with energy use feedback that shows their building’s energy use compared to a neighboring building. Buildings that reduce energy use will receive encouragement to continue conserving. The intern will work with two partnering utilities companies, FortisBC and BC Hydro. These partners will help provide energy use data for each building during the project.

Designing multi-family housing to boost social capital and psychological well-being

There is no more powerful correlate of human health and wellbeing than positive social relationships. Multi-family housing, through design, layout, and location, can exert a significant effect on local relationships, neighborhood trust and residents’ sense of belonging. We propose a program to gather, refine and illustrate the evidence linking design and social wellbeing in multi-family housing.

Evaluation of cyanide and thiosulphate lixiviant systems for KSM Seabridge gold circuit

Most of the gold that is produced by hydrometallurgical processes is recovered by cyanide leaching. However, the reactive nature of some minerals questions the applicability of cyanide technology for selected applications. The current research is designed to evaluate the cyanide technology as well as an alternative processing path for a particular material through extensive experimental program. The project will yield the mathematical models describing all chemical processes in each circuit, as well as mass and energy balances based on laboratory data and scientific reasoning.

En Route to 5G: Long-term Evolution (LTE) Enhancements for the Internet of Things (IoT) - Year Two

Cellular wireless communication has reached a level of coverage and reliability that it is considered a commodity. However, the dramatic increase in Internet traffic to and from wireless devices poses significant challenges for network operators. While the current growth of traffic is mostly due to consumers communicating more frequently and larger amounts of data over the wireless infrastructure, much of the future growth is predicted to come from non-human operated devices or so-called machine-to-machine (M2M) communication.

Characterizing phytochemical content of bioactive coffee leaf materials for use in coffee tea leaf beverages

Wize Monkey is currently the only maker of Coffee Leaf Tea in the world; they work in partnership with coffee producers in Nicaragua to develop alternative coffee based products. One of these is coffee leaf; a novel idea of harvesting leafs at optimal times to be used as a tea-based beverage. The leaf is harvested, dried, processed and blended to produce novelty based coffee leaf teas. Their business provides a humanitarian component providing stable work for up to 40 farm workers through-out the year to supply their product.

Modelling wood quality and its implications for lumber recovery in variable retention stands

For many reasons, forest management in Canada will be constrained by ecological and social forest management objectives. Along with meeting the diverse needs of society, forest managers will need to consider increased demands for renewable resources, such as wood. Wood, as opposed to concrete and steel, has a positive impact on the global carbon cycle but is also strong enough to build large buildings. Therefore, there will be an increased demand for stronger wood in the future.

Selective recovery of antimony and arsenic from copper sulphide concentrate

Many copper deposits contain significant amount of arsenic and antimony and being overlooked because of it. These impurities are currently subject to smelters penalty. Development of an efficient technology for removal of these impurities and converting them as sellable products will make a number of deposits economic that are currently not being mined. The current research will assist in identifying the most efficient technology for treating such complex minerals and to meet the rising demand for clear copper concentrates.

Developing advanced ore sorting sensing systems for gold deposits

This research focuses on novel sensor-based algorithms for sorting rocks and categorizing them as good (valuable) and bad (worthless) rocks. The sensors in the sorter will “see” the rocks characteristics, whether it’s their color or atomic density or the desired element and send a command to a mechanical arm, for example, to separate the two types of rock from each other.
