Disease outbreaks on animal farms can lead to emergency culls that require special handling of carcasses. Special truck liners, called biobags, are used for transportation and disposal to the designated landfill locations. These biobags are currently made from polyethylene (petro-based plastic) and are not biodegradable. They are sourced outside of Canada, at cost of $120/bag. The need in a potential disease outbreak for hog carcasses is estimated at 500 truckloads per week for up to 6 months (total 12,000 biobags). The proposed project will focus on developing cost-effective, biodegradable plastic sheet for biobags to substitute polyethylene. The biobag sheet needs to meet the required properties (puncture resistance, leak protection, biodegradability) and be black in colour. The new film material will be manufactured locally using sustainable biobased resources. Biodegradability is essential to reduce plastic waste in landfills and is aligned with Government of Canada's goals of replacing single-use plastics.

动物养殖场的疾病爆发可能导致紧急扑杀，需要对尸体进行特殊处理。特殊的卡车内衬，称为生物袋，用于运输和处置到指定的垃圾填埋场。这些生物袋目前由聚乙烯（石油基塑料）制成，不可生物降解。它们来自加拿大以外的地方，价格为120美元/袋。在潜在的疾病爆发中，估计每周需要500卡车的猪尸体，长达6个月（共12，000个生物袋）。拟议的项目将侧重于开发具有成本效益的，可生物降解的生物袋塑料板，以取代聚乙烯。生物袋片材需要满足所需的特性（抗穿刺性、防漏性、生物降解性）并且是黑色的。新的薄膜材料将使用可持续的生物基资源在当地生产。生物降解性对于减少垃圾填埋场的塑料废物至关重要，并与加拿大政府取代一次性塑料的目标相一致。
