- Waste Stream
- A specific category of waste generated by operations — such as general waste, recyclables, organics, or e-waste — that is collected and processed separately.
- Landfill Diversion Rate
- The percentage of total waste generated that is diverted from landfill through recycling, composting, reuse, or energy recovery.
- Single-Stream Recycling
- A collection system where all recyclable materials — paper, cardboard, glass, plastic, and metal — are placed in one bin and sorted at a processing facility.
- Commingled Waste
- Recyclable materials mixed with general waste, which typically reduces their recycling value and may result in the entire load going to landfill.
- E-Waste
- Discarded electronic equipment — computers, monitors, batteries, and mobile devices — that requires specialized recycling due to hazardous components.
- Circular Economy
- An economic model that keeps materials in use for as long as possible through reuse, repair, remanufacturing, and recycling, rather than disposing of them after single use.
- ISO 14001
- An international standard that specifies requirements for an environmental management system, including documented policies and measurable objectives.
- Source Reduction
- Actions taken before waste is generated — such as reducing packaging or switching to reusable supplies — to shrink the total volume of waste produced.
- Waste Audit
- A systematic assessment of the types and quantities of waste a facility generates, used to identify reduction opportunities and track progress against targets.
- Contamination
- The presence of non-recyclable or food-soiled materials in a recycling bin, which can render an entire container of recyclables unprocessable.
