									      SOLID WASTE AUDITING
Applications
• Setting waste diversion target (e.g., how much
  of the waste can be removed from the waste
  stream?)
• Developing SWM strategies (e.g., who among
  the waste generators should be the focus of
  IEC and enforcement efforts?)
• Designing SWM facilities (e.g. can the
  institution accommodate a Materials
  Recovery Facility or a composting site? What
  type of shredder is appropriate, if
  appropriate?)
 The solid waste audit process
Three major stages
1. Preparation and training
  –   Current disposal process and practices? Cost of
      collection and dumping? Existing office/point
      person for SWM? Is some form of recycling or
      reuse being practiced in the community? Use the
      six E’s framework as a guide.
2. Actual waste audit (weights and
   characterization)
  –   Pre-audit: coordinate with concerned offices,
      secure area, assistants (if needed), materials
3. Data consolidation
  –   Educated recommendations to implement SWM
      or improve existing SWM process
Case study: Silliman University
Research objective
• Assess preparedness of SU to implement
  a campus SWM program through the
  use of indicators following the six E’s
  framework.
Personal objective
• Scientifically prove that SU is, for the
  most part, inefficiently disposing their
  solid waste, and that there is much
  room for improvement.
 Case study: Silliman University
Audit Preparation
• Determined audit schedule and frequency.
• Coordinated closely with Buildings and
  Grounds Unit (obtained dumping fees,
  recycling practices) and the Food Services
  Unit (segregation practices).
• Secured area and materials such as platform
  scales, containers, protective gear.
• Calibrated containers to obtain volume (liters)
  in addition to weight.
• Obtained permission to conduct audit and
  request for solid waste to be temporarily set
  aside.
Case study: Silliman University
Actual waste audit
• Briefed assistants on objectives,
  methods, and safety.
• Weighed all of the solid waste (Kg) first
  before proceeding to characterize
  according to biodegradable,
  recyclable, special, and residual, and
  obtaining weight and volume of each
  category.
• Clean up.
Case study: Silliman University
Data consolidation and analysis (1 finding)
• More than half a tonne of garbage (668kg)
  was audited and characterized.
  Biodegradable and residual volume
  amounted to 2,029L or 2.03 cu.m
        2%
                                               Equates to at
             11%                               least 140 tonnes
                   15%
                         Biodegradable Waste   per year, much
                                               of which could
                         Recyclable Waste
                         Residual Waste
                         Special Waste /THW

      72%
                                               be diverted if
                                               segregated
                                               properly.
        Lessons Learned
• Scientifically grounded basis for SWM
  provides credibility for
  recommendations.
• Knowledge and subsequent linkages
  with local junkshops, composters,
  cooperatives.
• Tackling solid waste generation and
  disposal from a multidimensional
  perspective as opposed to the
  traditional engineering perspective.
