• Container selection and use protocols
• Transportation and collection schedules
• Documentation and record-keeping requirements
• Training and competency standards
• Audit and monitoring procedures
• Incident reporting and investigation processes
• Contractor selection and management
• Continuous improvement mechanisms

Policies must be regularly reviewed, easily accessible, and communicated effectively to all staff.

Risk Assessment

Conduct comprehensive risk assessments covering:

• Waste generation points: Map all locations where waste is produced
• Handling procedures: Identify risks at each stage from generation to disposal
• Storage arrangements: Assess adequacy and security of storage facilities
• Transportation routes: Evaluate internal and external waste movement risks
• Staff competency: Identify training needs and knowledge gaps
• Equipment suitability: Review container and handling equipment adequacy

Risk assessments should be reviewed annually and whenever significant changes occur.

Waste Minimization Strategies

The most effective waste management begins with waste prevention. Implementing the waste hierarchy—reduce, reuse, recycle, recover, dispose—delivers both environmental and financial benefits.

Reduction at Source

Procurement optimization:

• Review product specifications to minimize excess packaging
• Negotiate with suppliers for reduced packaging options
• Select products with minimal disposal requirements
• Implement just-in-time ordering to reduce expiry waste
• Consider total lifecycle costs including disposal in purchasing decisions

Inventory management:

• Implement first-in-first-out (FIFO) systems to minimize expiry
• Right-size stock levels to actual usage patterns
• Monitor slow-moving items and adjust ordering
• Establish inter-departmental sharing for excess stock
• Use inventory management technology for visibility and control

Clinical practice optimization:

• Review procedure packs for unnecessary items
• Customize surgical kits to actual requirements
• Train staff on efficient resource use
• Question "that's how we've always done it" practices

Reuse Opportunities

Where clinically appropriate and cost-effective:

• Reusable surgical instruments: Invest in high-quality instruments with long service lives
• Reusable sharps containers: Consider robotic sharps containers that are emptied and returned
• Textile systems: Evaluate reusable gowns, drapes, and linen versus disposables
• Equipment reconditioning: Refurbish rather than replace where safe and economical

All reuse decisions must prioritize infection control and patient safety.

Recycling Programs

Maximize diversion from waste streams through recycling:

• Paper and cardboard: Establish dedicated collection throughout facility
