GHD Canada seeks to remain an industry leader in organic waste management and recycling. Organic waste makes up about 40% of all waste in Canada. Less than 10% of this organic waste is recycled; the remainder is buried in landfills or incinerated. This practice is both wasteful and potentially polluting. Organic waste contains valuable non-renewable resources such as phosphorus (P), which is an essential nutrient for plant growth. However, the careless use of P can compromise food security (if mineral fertilizer required for food production becomes unaffordable or unavailable), and can cause aquatic pollution (if excess P is discharged to waterways). As a result, several provinces and municipalities across Canada are moving to regulate organic waste management to encourage recycling and preserve the environment. This study intends to assess urban organic waste management as a solution to the joint issues of phosphorus scarcity and pollution. Cities provide unique opportunities for P management because organic products such as food and the subsequent waste produced from consumption are concentrated there. The research proposed here will use Montreal as a case study to assess how new waste management policies currently proposed across Canada might affect P flows through cities, and how the recycling of municipal organic waste as compost and similar products can conserve nutrients and reduce pollution. GHD Canada has approached McGill University to collaborate on this project. GHD Canada is a division of an international consulting company with a strong investment in environmental engineering and sustainability. McGill's Department of Bioresource Engineering provides GHD with vital expertise in organic waste processing alternatives, nutrient cycling, phosphorus, and urban studies.

GHD Canada致力于成为有机废物管理和回收的行业领导者。有机废物 占加拿大所有垃圾的40%。这些有机废物中只有不到10%被回收利用，其余的则被 埋在垃圾填埋场或焚烧。这种做法既浪费又可能造成污染。有机废物 含有宝贵的不可再生资源，如磷（P），这是一种植物必需的营养素 增长然而，不小心使用磷肥会危及粮食安全（如果粮食需要矿物肥料）。 生产变得负担不起或不可用），并可能导致水生污染（如果过量的磷排放到 水道）。因此，加拿大的几个省和市正在采取行动来规范有机食品。 废物管理，以鼓励回收和保护环境。这项研究旨在评估城市 有机废物管理作为解决磷短缺和污染的共同问题。 城市为磷管理提供了独特的机会，因为有机产品，如食品和 消费后产生的废物集中在那里。本研究将使用 蒙特利尔作为一个案例研究，以评估加拿大目前提出的新废物管理政策如何 可能会影响P流通过城市，以及如何回收城市有机废物作为堆肥和类似 产品可以保存营养和减少污染。 加拿大GHD已与麦吉尔大学接洽，就该项目进行合作。加拿大GHD是一个部门， 一家在环境工程和可持续发展方面有着强大投资的国际咨询公司。 麦吉尔大学的生物资源工程系为GHD提供了有机废物方面的重要专业知识 加工替代品、养分循环、磷和城市研究。
