The Problem

Routine use of single-use patient bags and bottles in hospitals increases plastic throughput and associated lifecycle greenhouse gas emissions. These are avoidable single use plastics that can be eliminated at source.

The Solution

Implement a substitution and behavior-change practice requiring individuals to use reusable personal bags and refillable water bottles in place of single-use disposable packaging and containers. One study showed that following implementation, the two hospitals (University Hospital and Victoria Hospital, Ontario) recorded a 45.7% reduction in patient belongings bags, equivalent to roughly 252 kg of material waste, 2.1 t CO₂e, and CAD 1,260 in annual savings.

Co-Benefits
Reduced supply procurement costs
Reduced waste handling workload
Reduced single-use plastic throughput
