A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction Gangue
DownloadSpring 2015
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

The redevelopment of understories is an often-overlooked aspect of forest restoration following anthropogenic disturbances. In my research I explored the feasibility of actively restoring forest understories through seedling planting. First, I examined the quality of nursery-grown boreal shrub...

Aggregate Resource Extraction: Examining Environmental Impacts on Optimal Extraction and Reclamation Strategies
DownloadFall 2014
Aggregate resources are naturally occurring deposits of sand, gravel and crushed stone that are integral components to the construction of everything from roads and sidewalks, to hospitals and schools. Mining these resources can release deleterious sediments, salt and chemicals into watercourses,...

An evaluation of hitchhiker seedlings with native boreal species as a revegetation tool of industrially disturbed sites in Alberta, Canada
DownloadSpring 2020
Herbaceous forbs hitchhiked, or co-grown, with a woody species, is a solution to establish both native woody and herbaceous species at recently disturbed sites. The broad study objectives were to (1) assess the growth of fireweed hitchhiked with three deciduous woody species and one conifer over...

An Investigation of Potential Weed Management Practices and Multivariate Assessment Parameters for Alberta's Oil Sands Reclamation Efforts
DownloadSpring 2018
Reclamation efforts that promote the re-establishment of native tree and plant communities subsequent of large-scale oil sands mining land disturbances are crucial in restoring natural ecosystems. It is important that reclamation procedures capable of facilitating the establishment of native...

Assessing the long-term impact of acid deposition and the risk of soil acidification in boreal forests in the Athabasca oil sands region in Alberta, Canada
DownloadFall 2012
Significant amounts of SO2 and NOx have been emitted from the Athabasca oil sands region (AOSR) in Alberta, Canada, in the past several decades. The impact of acid deposition on forest ecosystems and the risk of soil acidification were assessed in jack pine (Pinus banksiana) and trembling aspen...

Biodegradation of Hydrocarbons in Bitumen: Exploring Plant-Assisted and Microbial Stimulation Techniques
DownloadFall 2020
While bitumen is one of the oldest construction materials in the world and currently provides an important fuel needed to sustain our modern lifestyle, the disturbances caused by extracting and refining this material are considerable, with 895 km2 of land being disturbed in Alberta as of 2018...

Spring 2024
Hydrolyzed polyacrylamide (HPAM) is a common flocculant used in oil sands tailings dewatering technologies. Although HPAM is regularly used in tailings treatment and will eventually be incorporated into the reclaimed landscape of the oil sands, there are knowledge gaps surrounding the environment...

Bitumen Extraction, Indigenous Land Conflicts, and Environmental Change in the Athabasca Oil Sands Region, 1963-1993
DownloadSpring 2021
This dissertation examines the first development phase of the Alberta oil sands industry from the 1960s to the early 1990s. It draws on public and private records from archives in Canada and the United States, the results of collaborative research with the Fort McMurray Métis, and oral history...

Challenges of utilizing municipal compost as an amendment in boreal forest reclamation subsoil material
DownloadFall 2018
Forest reclamation sites are often located in areas not suited for agriculture and therefore have poor soil conditions. To assist in the rehabilitation of forests on these types of sites, organic amendments can be used. Close to large urban centers, compost derived from municipal organic waste...
