  1. Wrap Up What we’re wasting, why we’re wasting it, and what we can do about it Mike von Massow

  2. Residential Food Waste • We did • Audits of all waste put to the curb • Only a portion of consumer waste • Plate waste • Meals carried from home • Home composting • Garburators • Surveys on attitudes and behaviours • Develop an understanding of what causes waste in the home

  3. Residential Food Waste • Average household generates 3.5-4.5 kg of food waste per week • 53% avoidable • 11% possibly avoidable • 36% unavoidable • Waste is highly variable – lots of difference between houses

  4. Fruits and Veg’s • 50%-60% of total • 0.27-3.9Kg kg per day • 40% of this unavoidable • Not strong correlationbetween avoidable andunavoidable • High frequency • 70% of avoidable total

  5. Others • Meat and Fish 0.05 kg per day • 8% of total • 55% avoidable – more than half of households • Dairy and Eggs 0.03 kg per day • 5% of total • 70% avoidable – lower frequency

  6. Others • Cereals and grains 0.08 kg per day13% of total 100% avoidable -high frequency • Other 0.09 kg per day • 70% unavoidable – high frequency • Often in garbage stream

  7. How do you decide what to discard?

  8. The Waste Aware • Higher awareness of waste • More sophisticated thinking • Less types of waste/simple measures for waste • Worried about waste • Feel guilty about waste • Find it convenient to deal with waste • Produce less waste

  9. The Food Aware • Much more connected to food • Appreciation or concern for food • Special diet • Compost • Nutrition labels • Produce Less Waste

  10. Convenience Driven • Waste less of a concern • Eat more processed food • Actually less organic waste at home but . . . • More recyclables • Eat out more • Buy groceries and throw them away

  11. The Frantic Family • Higher levels of waste • And more likely to “cheat” • Often aware of waste and feel bad but can’t do better • More likely to shop at big box stores • More likely to do big shops • Often eat out because of kid’s schedule

  12. A Couple of Key Learnings • Smaller unit of analysis is better • We should strive to have consistent definition and terminology to improve comparability • Work to understand the sources of variability
