Ultimate disposal of used vehicle tires continues to be a major challenge around the world. On average, Manitoba produces about 1.4 million tires per year, which are being recycled by two recycling companies including OTR Recycling Corp. Despite the various products made from recycled tire, 20% of used tires cannot be recycled due to the limited applications which they can be used. Therefore, OTR Recycling Corp. is actively looking for new applications. One potential application is use as aggregate for septic fields. However, at present time, there are no reported studies available on tire derived aggregate (TDA) performance as aggregate in septic fields in the areas with low temperature conditions such as Manitoba and other parts of Canada. The regulatory agency of Manitoba has concerns about the possible adverse effects, if any, from using tires in the leaching field systems. The two primary concerns are: 1) TDA might leach contaminant which can affect groundwater quality, and 2) whether TDA can perform as well as a conventional leaching field system. The goal is, therefore, to address those concerns by collaborating with Dr. Yuan at the University of Manitoba to conduct lab scale experiments to answer leaching questions and follow up this up with a field-scale study to evaluate TDA as a replacement for natural aggregate in the cold Canadian environment. The primary goal of this research is to characterize and quantify the leachate composition in aquatic environments that are expected to be encountered during septic field application. This study will provide primary valuable information on the suitability of TDA to act as a substitute for rock aggregate in a leach field in Canada. This information is essential for the environmental regulatory body to make a decision. It is also important for the tire recyclers who are seeking a new market for TDA. In addition to the economic benefit, TDA benefits the environment twofold by eliminating the need to excavate rock and the beneficial reuse of what was considered a waste.

二手汽车轮胎的最终处置仍然是世界各地的一大挑战。平均而言， 马尼托巴省每年生产约140万个轮胎，由两家回收公司回收 包括OTR回收公司尽管有各种由回收轮胎制成的产品，但20%的旧轮胎不能 由于它们可以使用的应用有限，因此可以回收。因此，OTR回收公司正在积极地 寻找新的应用程序。一种潜在的应用是用作化粪场的集合体。然而，在 目前，还没有关于轮胎衍生集料(TDA)作为集料的性能的报道 在马尼托巴省和加拿大其他地区等低温地区的化粪场。这个 马尼托巴省的监管机构担心，如果在汽车上使用轮胎，可能会产生不利影响 淋滤场系统。两个主要的担忧是：1)TDA可能会渗出污染物，这可能会影响 地下水质量，以及2)TDA是否能像传统的淋滤场系统那样发挥作用。这个 因此，目标是通过与马尼托巴大学的袁博士合作来解决这些担忧 进行实验室规模的实验以回答浸出问题，并通过现场规模的研究进行后续研究 在加拿大寒冷的环境中，评估TDA作为天然骨料的替代品。 这项研究的主要目标是表征和量化水中渗滤液的组成。 在化粪池现场应用过程中预计会遇到的环境。 这项研究将为TDA作为岩石替代品的适宜性提供有价值的初步信息 聚集在加拿大的一块浸出地里。这些信息对于环境监管机构来说是必不可少的 做个决定。这对正在为TDA寻找新市场的轮胎回收商来说也很重要。此外 TDA的经济效益是双重的，因为它消除了挖掘岩石和 对被认为是废物的有益的再利用。
