Louisbourg Seafoods Limited harvests (April to October) and sells 5 millions lbs of Snow Crab (Chionoecetesopilio) annually. The commercially desired product are the legs and shoulders generating resultant wastestreams from the bodies of the snow crabs (approximately 1/3 of the crab). Currently Louisbourg Seafoods paysfor snow crab waste to be landfilled and they are interested in alternative, more environmentally sustainablepractices. In a landfill, snow crab residues will decompose and generate some small amount of fixed carbon,however much of the carbon is released into the environment as CO2 during decomposition and aside fromsome microbial benefits none of the remaining interesting chemicals are utilized during landfill decomposition.The chemical composition of the snow crab includes a high content of protein (34.2% dw) and essential aminoacids; they also have fat (17.1% dw), with a high proportion of polyunsaturated fatty acids and approximately28.5% dw minerals (calcium, phosphorous, and magnesium) making this waste stream very intriguing as astarting biomass for the generation of biochar that has a more interesting and likely more valuable chemicalcomposition than forestry biochars.

路易斯堡海鲜有限的收获（4月至10月），每年出售500万磅的雪蟹（Chionoecetesopilio）。商业期望的产品是从雪蟹体体产生的腿和肩膀（大约1/3）。目前，路易斯堡海鲜为被垃圾填埋的雪蟹浪费付费，他们对替代性，更环保的实践感兴趣。在垃圾填埋场中，雪蟹残留物将分解并产生少量的固定碳，但是大部分碳被释放到环境中，因为二氧化碳在分解过程中，并且从少量微生物中受益，剩下的有趣的化学物质在垃圾填充分解过程中都没有使用。它们还含有脂肪（17.1％DW），多不饱和脂肪酸比例很高，大约28.5％的DW矿物质（钙，磷和镁），使这种废物流非常有趣，因为生物char的产生比生物char产生了更有趣，可能更有价值的化学物质化学物质比森林生物库。
