Sustainable Aerobic Landfill Technologies (SALT) Inc. is forging a research partnership with Western University to evaluate the performance of an aerobic bioreactor landfill under controlled laboratory conditions. The envisaged landfill will be a laboratory scale model of the company's full scale landfill located in Fort McMurray, in the Regional Municipality of Wood Buffalo, Alberta. SALT Inc's motivation for the partnership is to obtain performance data and analysis to validate its aerobic bioreactor landfill technology and to confirm the predicted environmental and economic benefits of the technology, namely, odor elimination, increased greenhouse gas credits, reduced landfill footprint and extended landfill life, leachate containment and elimination prior to seepage, and minimal groundwater impact. To generate the required data, two aerobic bioreactor landfill models each measuring 1.22 m wide x 0.61 m long x 1.83 m deep will be installed and monitored in the laboratory at a temperature of 25± 2 oC. The bioreactors will be filled with waste sampled from the Wood Buffalo landfill. Vertical and horizontal perforated PVC pipes will be installed in each box for compressed air and moisture injection. Effluent from the boxes will be sampled at prescribed intervals and analyzed for dissolved organic carbon locations, metals, sulphate, pH and alkalinity. Water balance measurements and analysis will also be carried out on each bioreactor. The data will be used to develop a computer model for aerobic bioreactor landfill and compared to the field performance of the full-scale landfill in Fort McMurray. The project is of great importance to SALT Inc. because, by having real performance data on the aerobic bioreactor landfill, the company will be able to assess actual reductions in methane emissions and hence accelerate its drive to become carbon neutral. The project will train one doctoral student and one undergraduate research assistant in modern landfilling and greenhouse gas mitigation methods, areas of expertise that would appeal to Canadian engineering consulting firms and municipal and provincial governments.

可持续的好氧填埋技术（SALT）公司。正在与西方大学建立研究伙伴关系，以评估受控实验室条件下的好氧生物反应器填埋场的性能。设想的填埋场将是该公司位于阿尔伯塔伍德布法罗地区市麦克默里堡的全尺寸填埋场的实验室规模模型。SALT公司的合作伙伴关系的动机是获得性能数据和分析，以验证其有氧生物反应器填埋技术，并确认该技术的预测环境和经济效益，即消除气味，增加温室气体信用，减少垃圾填埋场的足迹和延长垃圾填埋场的寿命，渗滤液的遏制和消除渗漏之前，和最小的地下水影响。为了生成所需数据，将在实验室安装两个好氧生物反应器填埋模型，每个模型的尺寸为1.22米宽x 0.61米长x 1.83米深，并在25± 2摄氏度的温度下进行监测。生物反应器将装满从伍德布法罗垃圾填埋场取样的废物。垂直和水平穿孔PVC管将安装在每个盒子里，用于压缩空气和水分注入。将在规定的时间间隔对箱中的流出物进行取样，并分析溶解有机碳位置、金属、硫酸盐、pH值和碱度。还将对每个生物反应器进行水平衡测量和分析。这些数据将被用来开发一个好氧生物反应器填埋场的计算机模型，并与麦克默里堡的全尺寸填埋场的现场性能进行比较。该项目对SALT公司非常重要。因为，通过掌握好氧生物反应器填埋场的真实的性能数据，该公司将能够评估甲烷排放的实际减少，从而加速其实现碳中和的努力。该项目将培训一名博士生和一名本科生研究助理，内容涉及现代填埋和温室气体减排方法，这些专业领域将吸引加拿大工程咨询公司和省市政府。
