Designer Biochar-Coke Mixtures to Remove Naphthenic Acids from Oil Sands Process-Affected Water (OSPW)Download
The objective of this 6-month pilot experimental study was to test the ability of biochars derived from Alberta biomass and an oil sands petroleum coke to remove selected organic acids from water. To this end, we selected one biochar produced from wheat straw and made by the Alberta Biochar...
Effects of Biochar, Fertilizer and Shelter Treatments on the Vegetation Development following Coal Mine ReclamationDownload
Poor quality cover soil, a lack of propagules, and availability of suitable microsites can be serious challenges in the re-vegetation success of surface mines. In my thesis research, I examined the response of total cover, species richness and community composition of colonizing vegetation on a...
Surface mining activities cause severe adverse effects on soils. Scientists across the world have used different physical, chemical and biological reclamation techniques to recover mining disturbed areas. The effectiveness and efficiency of reclamation techniques is crucial to reclamation...
The addition of biochar to soil is believed to have positive effects on soil nutrient retention. Enhanced cation exchange capacity, water holding capacity and soil aeration are thought to be some of the benefits provided by biochar. In Alberta, reclamation of disturbed sites may be hastened by...
Carbon and Nitrogen Mineralization and Microbial Succession in Oil Sands Reclamation Soils Amended with Pyrogenic CarbonDownload
Land reclamation of oil sands disturbed boreal forests in Alberta is a challenging task facing companies with surface mine leases. The government requires reclamation to equivalent land capability, which is a vague statement at best. Agronomic theories and methodologies have been applied in the...
Effect of Biochar on Soil Microbial Communities, Nutrient Availability, and Greenhouse Gases in Short Rotation Coppice Systems of Central AlbertaDownload
Short rotation coppice (SRC) systems using willow (Salix spp.) grown on marginal soil, amended with biochar may represent a promising source of renewable green energy for rural communities of Alberta. The Ohaton Wood Energy project, an agroforestry site located in Camrose County, is one of...
Pine sawdust biochars produced at 300 and 550 °C with and without steam activation were assessed for its sorption capacity for phosphate and copper (Cu (II)) in aqueous solutions using batch sorption experiments, including isotherm and kinetic studies. This study implied that pine sawdust...
Biochar has received significant attention as an innovative sorbent for treating heavy metal contamination due to its high surface reactivity and sorption capacity, ease of manufacture and low production cost. Most studies involving chromium removal from solution by biochar have focused on...
Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...
Greenhouse gas (GHG) emission is one of the important environmental issues that world is facing today. Biomass usage, specifically capturing energy from biomass that would otherwise decay, is one the of many options available to mitigate the impact of the buildup of GHG emissions from fossil...
