Landfill Lifecycle Planning

  1. 1. Landfill Lifecyle Planning: A Necessity for Efficient Operation and Capital Expenditure
  2. 2. Jeffrey J. Breedlove, P.E.
  3. 3. CHATTANO OGA
  4. 4. Overview • Permit Designs of the early 1990’s often leave much to be desired operationally • 15 years of landfill operation have taught us much • Many landfills can benefit from a Life of Site Staging Plan review
  5. 5. Why Plan?
  6. 6. Why Plan?
  7. 7. “ Insanity is continuing to do the ” same thing over and over, and expecting different results. ~ Einstein (attributed)
  8. 8. Initial Impetus GET THE PERMIT
  9. 9. Initial Impetus GET THE PERMIT Many failures Public opposition Political road blocks Success?
  10. 10. Permit Conditions GOT THE PERMIT Emphasis on regulatory issues Environmental protection was paramount   Rote presentation of cell sequencing Designers Inexperienced in Landfill Operations Operations not adequately addressed   Economic efficiency often ignored
  11. 11. The Hand We’ve Been Dealt • Permit Drawings • Staging Plans • Ops Plan
  12. 12. 15 Years of Experience

  90. 90. Landfill Staging Knowledge → Planning Planning → Success Success = $
  91. 91. Knowledge is Power; Time is Money Knowledge = Power- eqn. 1 Time = Money - eqn. 2 High school physics has taught us that Power = Work/Time. From eqn. 2, Time = Money, so Power = Work/Money From eqn. 1, Knowledge = Power, so Knowledge = Work/Money Rearranging: Money = Work/Knowledge
