Waste Management Facility Waste Composition Study
Client: Oxford County
Location: Oxford County, ON
Start & End Date: March 20 – March 31, 2017
As an initiative of Oxford County’s Zero Waste Plan, Oxford County contracted AET Group Inc. (AET) to conduct a Waste Management Facility waste composition study to report on the current waste disposal situation occurring in the residential sector of Oxford County. This study included a three week sampling period of 75 inbound Waste Management Facility material loads for physical auditing and a three week sampling period of 222 inbound Waste Management Facility material loads for visual volumetric auditing.
Objectives:
- Collect inbound waste management facility waste composition data through the identification of types and quantities of generated waste through physical and visual auditing
- Develop a summary report that details the findings of the waste audit study for the two sources material
Description:
Two Waste Management Facility audits were performed by the AET team. The first was an Inbound Waste Management Facility Audit that was physically audited. Material from 5 pre-determined material sources were sampled over three weeks. This material was sorted into 34 categories to determine the material composition. The second audit was also an Inbound Waste Management Facility Audit but was visually audited. This inbound landfill material was sampled from all available material sources at random over three weeks. Vehicles audited were randomly selected as they entered the waste management facility. Each load was given a volumetric estimation for the different material types. Material samples were then converted from volumetric composition to weight equivalents using the net weights of each load, the size and fullness of each truck and bulk up to date density conversion factors for each material type.
