Practical waste management

• Understand impact on the business
• Establish clear Organisation and Responsibilities
• Implement a waste minimisation programme
• Identify and quantify waste streams
• Assess options for elimination/re-use/recovery/dis
  posal
• Safe storage and handling
• Labelling, record-keeping
• Selecting a waste contractor
• Staff training
• Waste audits

True cost of Waste

• Cost of disposal
• PLUS
• lost raw material
• handling processing
• (cost of energy, rework, etc)
• labour costs
• lost production
• insurance premiums
• (waste storage incidents, etc)

True cost 5 - 20 times direct cost of disposal

Waste minimisation programme

• 1. Commitment
• 2. Complete inventory of all wastes
• 3. Quantify amounts and costs of wastes
• 4. Prioritise
• 5. Develop Action Plan
• 6. Set realistic targets and reduction goals
• 7. Allocate resources (money, time)

Measuring waste

• Re-look at your processes
• by Department/Area/Unit operation
• use checklists, flowsheets, inventories
• check waste disposal records
• Quantify waste types and costs
• components
• best estimate of monthly/yearly amounts costs
• opportunities for elimination/reduction
• You get what you Inspect, not what you expect

Setting Priorities

• Quantity
• Cost of waste
• Environmental impact
• Regulation
• Customer needs
• Begin with the obvious opportunities

Waste reduction ideas

• Increase purity of raw material specification
• Optimise packaging of raw materials and products
• Control process to minimise rejects
• Re-use or recycle by-products
• Re-work off-spec. products
• Train operators to raise awareness
• Implement preventative maintenance

Waste segregation and storage

• Recycle opportunities
• oil, wood, paper, plastics, glass, scrap
  metal, solvents, steel drums, biodegradable
  waste, printer cartridges, fluorescent tubes,
  etc.etc.
• Storage
• treat wastes as products
• appropriate containers
• no mixing of incompatible materials
• labelling
• pollution prevention (e.g. bund walls)
• regular inspection

• External audits
• off-site disposal facilities
• waste hauliers
