The legalization of cannabis for recreation purposes in Canada has opened a large market to Canadianproducers and distributors. Cannabis products based on THC, which is found predominantly in the leaves andfruits of the plant, however, cause a logistic problem through the disposal of stems, stalks and roots. Theresidues only contain a small proportion of active ingredients and cannot be used for THC extraction.There are currently no prescribed methods, under the Canadian Cannabis Act, for their disposal. The onlyprovision is that the residues must be rendered inert and unusable, most generally through a complex dispersionprocedure including shredding and mixing with other products.The quantity of residues is bound to increase with increasing cannabis production, and it becomes imperative todevelop and implement valorisation techniques that go beyond basic composting or incineration.An innovative, value-added, alternative for the stems and roots is to further process the residues to extractcellulosic sugars to produce cannabis edible products. This project aims to develop the key biomasspre-treatment step of this process.

加拿大用于娱乐目的的大麻合法化为加拿大生产商和分销商打开了一个巨大的市场。然而，基于四氢大麻酚的大麻产品主要存在于植物的叶子和果实中，但在处理茎、茎和根时会造成物流问题。残留物仅含有一小部分活性成分，不能用于 THC 提取。根据加拿大大麻法，目前没有规定的处理方法。唯一的规定是，残留物必须变得惰性且无法使用，最常见的是通过复杂的分散程序，包括粉碎和与其他产品混合。随着大麻产量的增加，残留物的数量必然会增加，因此必须开发和实施增值技术超越基本的堆肥或焚烧。茎和根的一种创新的、增值的替代方案是进一步加工残留物以提取纤维素糖来生产大麻食用产品。该项目旨在开发该过程的关键生物质预处理步骤。
