Title: Introduction to Waste Management


1
Introduction to Waste Management
  • Definition The disposal, processing,
    controlling, recycling and reusing of waste to
    maintain a habitable environment

2
Two main paths for managing waste
  1. Waste diversion
  2. Waste disposal

3
Waste Diversion
  • Managing solid waste in a way that reduces the
    amount of waste that needs to be stored or
    incinerated (burned)
  • Includes 3 Rs (reducing, re-using, re-cycling,
    composting/biodegradation)

4
Waste Disposal
  • Two main options
  • Burning (incineration and advanced thermal
    treatment ?ATT)
  • Burying (underground in a landfill)
  • Issues environmental drawbacks, expensive (in
    Canada in 2000, 11 million tonnes disposed at a
    cost of 6 billion !!)

5
Basic types of waste
  1. Solid waste (garbage, compost, recyclables etc)
  2. Liquid waste water (sewage, sludge, biosolids)
  3. Nuclear waste (from uranium)
  4. Gaseous waste (carbon dioxide)

6
Types of solid waste
  • Can be defined as materials that are unwanted by
    the producer, by-products from production or a
    product that is consumed (like a magazine or the
    packaging from a product like a cereal box)

7
Types of solid waste
  • Biodegradable (organic) matter from fruits,
    vegetables, meat, dairy, grains, fats, paper,
    hair etc
  • Recyclable glass, plastic, paper, some metals
    etc
  • toxic (hazardous) E-waste (computers, cell
    phones), paint, batteries etc
  • Medical waste needles
  • Inorganic non-recyclable, non-toxic plastic
    wrapping, granola bar wrappers etc (aka regular
    garbage)
