Recently, municipal solid waste (MSW) has been recognised as a valuable resource that can be converted intox000D
useful products via microbially mediated transformations. Although various methods are available for thex000D
treatment of organic waste, anaerobic digestion (AD) appears to be one of the most promising approaches. ADx000D
exhibits great potential in both environmental and social sustainability by providing biofuels from thex000D
renewable feedstock with nutrients recovered able to be used as fertilizer. Anaerobic digesters can be operatedx000D
under liquid (wet), semi-solid, or solid-state (dry) conditions. Solid-state AD using a liquid inoculumx000D
recirculation-percolation method of operation at psychrophilic temperatures is a promising, cost-effectivex000D
option as it results in an exportable dry organic fertilizer in addition to the production of a green energy source.x000D
Having reverse osmosis (RO) as a post treatment process for the treatment of liquid leachate or reject water canx000D
produce a high quality, treated, liquid nutrient source for agricultural activities. The integration of the recoveryx000D
of nutrients (as organic fertilizer) along with energy recovery through AD could largely improve the bioenergyx000D
efficiency and fertilizer quality, and also provide options for water reuse in non-potable applications. In ourx000D
recently completed project, the aforementioned technique was successfully experimented using a lab-scalex000D
approach. In this proposed study, a scale-up study (i.e. 200 times bigger than the lab-scale digester) will bex000D
conducted to validate the lab-study results and to redesign the post treatment techniques suchx000D
coagulation-flocculation/RO process, rendering them optimal for the scale-up digesters' effluent/rejectx000D
wastewater. The outcome of this scale-up study will significantly add value for Bio-Terre Systems Inc., andx000D
Canada in general. In effect, this project aims to develop energy efficient solutions for municipal food sectors,x000D
and preserve the quality of our environment by reducing greenhouse gas (GHG) emissions. In addition, thex000D
end-product can be used as a valuable organic fertilizer and treated water can be reused forx000D
non-potable/industrial purposes.
