In Atlantic Canada, fisheries and seafood processing are major industries contributing to the local economy. Shellfish industry, particularly snow crab, make up a significant waste stream from this industry. The high moisture content of the crab by-product makes it challenging to valorize. Hydrothermal carbonization (HTC), a hydrothermal process involving biomass in the presence of water, is a simple and effective means of valorizing high moisture biomass, which could negate all or part of the drying process. The main product of HTC is a solid called hydrochar, which has various applications (for example, fuel and bioadsorbent). In this thesis, the hydrochar properties produced from snow crab (Chionoecetes Opilio) are studied to determine the effect of operating conditions on crab hydrochar and assess the best applications. Chapter 2 of this thesis includes a review of the literature on the existing hydrothermal carbonization of various feedstock from lignocellulosic non-lignocellulosic to marine biomass. ...
