Dairy Distillery (DD) produces the world's first vodka from milk permeate called Vodkow. In addition to potable spirits, DD has been producing hand sanitizer since March 2020 and plans to expand into the fuel ethanol market. Most alcohol production is based on the fermentation of non-waste agricultural substrates, such as cereals, potato starch, molasses from sugar beet, beetroot, and fruits. The wastes created by these fermentations are characterized by a low pH (acidic) and high levels of nutrients, and are an environmental liability due to their potential to create anoxic dead zones in downstream aquatic ecosystems. As an alternative to being treated in wastewater treatment plants, wastes from these fermentations have been used - with or without pretreatment - as fertilizers. However, no study to date has evaluated the potential of stillage from milk permeate fermentation to be used as such. Milk permeate is a lactose (milk sugar) rich by-product of ultrafiltered milk production. Ethanol made from milk permeate has half the carbon intensity as traditional corn ethanol and 1/6 the CO2 emissions associated with gasoline. Accordingly, the proposed project will assist with making the production of a low carbon intensity biofuel more feasible. The reduction in carbon emissions from a milk permeate biofuel plant would be equivalent to permanently removing 2,500 cars from the road. The goal of this partnership is thus to convert the waste stream into a valuable by-product (i.e., a fertilizer). Doing so would have a significant and positive impact on DD's capital and operating costs, and accelerate their plans to build new larger plants to produce low-carbon ethanol biofuel. In addition to directly supporting DD, expansion of ethanol production from milk permeate to other provinces will reduce costs to farmers of disposing of this waste, lead to job creation and contribute to a greener dairy-based economy. In addition to benefiting Canadians, this project directly addresses 7 of 17 United Nations strategic development goals associated with clean water, energy and environmental sustainability.

Dairy Distillery（DD）生产了世界上第一种来自牛奶渗透物的伏特加，称为Vodkow。除饮用酒精外，DD自二零二零年三月起一直生产洗手液，并计划扩展至燃料乙醇市场。大多数酒精生产是基于非废弃农业基质的发酵，如谷物，马铃薯淀粉，甜菜糖蜜，甜菜根和水果。这些发酵产生的废物的特点是pH值低（酸性）和营养素水平高，并且由于其在下游水生生态系统中产生缺氧死区的潜力而具有环境责任。作为在废水处理厂处理的替代方案，这些发酵产生的废物在经过或不经过预处理的情况下被用作肥料。然而，迄今为止还没有研究评估来自乳渗透物发酵的釜馏物原样使用的潜力。 牛奶渗透物是超滤牛奶生产中富含乳糖的副产品。从牛奶渗透物中提取的乙醇的碳强度是传统玉米乙醇的一半，二氧化碳排放量是汽油的六分之一。因此，拟议项目将有助于使低碳强度生物燃料的生产更加可行。牛奶渗透生物燃料工厂减少的碳排放量将相当于从道路上永久清除2,500辆汽车。因此，这种伙伴关系的目标是将废物流转化为有价值的副产品（即，肥料）。这样做将对DD的资本和运营成本产生重大而积极的影响，并加快他们建造新的大型工厂以生产低碳乙醇生物燃料的计划。 除了直接支持DD之外，将牛奶渗透物乙醇生产扩大到其他省份将降低农民处理这种废物的成本，创造就业机会，并促进更绿色的乳制品经济。除了使加拿大人受益外，该项目还直接涉及与清洁水、能源和环境可持续性有关的17项联合国战略发展目标中的7项。
