Expressed in percentage the weight of material disposed by High Temperature Closed Burning as against the waste stream handled.
- Acceptable average – < 60% for Methodology-A & < 20% for Methodology-B.
Averages by %
Averages by Weight
Intervenors
- True increase expected during clearing of collection backlogs, special waste pickups, low segregation rates, and such
- Apparent increase chiefly due high moisture content and errors in re-sorting process
- True decrease chiefly due to adoption of alternate methodologies which re-define recoverables
- Apparent decrease chiefly due errors in weigment and recording
Actions to be taken
- Check weighing and recording procedures in the Resource Recovery Centre
- Intensify supervision
- Liaise with personnel involved in collection and transport to improve segregation rates and decrease moisture content
- Conduct individual supervisory checks on personnel involved in re-sorting and take appropriate corrective measures
Confounders
- Bulk streams and single special streams with high percentile of incinerable material can mislead observations.
- Sundays and Public holidays can show higher percentiles due to collection & handling issues.
