Enhancing dewatering, drying, combustion and utilization of pulp and paper mill biosludge

2017/18-2019/20 • $564,600 • PI,CO
Canadian pulp and paper mills generate more than 20 million cubic metres of raw biosludge per year. Biosludge is generated during biological wastewater treatment and consists to >98% of water with the remainder being bacteria and tree residues. Energy intensive dewatering can decrease the water...

Developing biofilm-based microalgal bioreactors for the efficient production of fuels, chemicals and clean water

2014/15-2017/18 • $472,000 • PI,CO
Using microalgae to convert carbon to biomass is one of the most promising technologies for developing renewable fuels. Algae produces more biomass than conventional crops such as corn and sugar beet, can be used to capture carbon and can be used in water treatment processes. Despite these...

Fundamental studies of drying, combustion and ash properties of biomass and impacts of pulp and paper mill operations

2012/13-2015/16 • $1,876,000 • PI,CO
Pulp and paper mills in Canada require large amounts of high pressure steam and electric power to operate. About two-thirds of the energy required is supplied by burning the concentrated black liquor (spent pulping liquor) in recovery boilers. The remaining is from biomass boilers, known...

Bioreaction engineering to maximize mixed microbial systems that convert wastes into value added

2011/12-2015/16 • $150,000 • PI
This grant will continue to develop the applicant's highly successful program in Environmental Bioprocess Engineering, which involves using biological materials and biocatalysts for processes that benefit the environment. In order to have a sustainable future, Canada needs to produce more of its...

Microalgal biorefinery:Biofilm photo-reactor and extraction methods

2010/11-2012/13 • $230,000 • PI,CO
Microalgal technologies, used as a method of conversion of (sun)light to liquid fuels, hold several advantages over conventional crops: they can produce up to 100 times more biomass per unit of crop area; the lipid content of this biomass can be up to 70% (dry basis); the doubling time can be in...
