Overall Productivity Rate (KPI-7)

Measures the weight in kilograms, the waste that is handled by all individuals involved in all handling processes, in an hour. Expressed as kg / person / hour

Averages in %

Averages by Weight


Intervenors

  • Acceptable average – 40 / kg / person / hour
  • True increase expected when segregation rate of waste delivered increases
  • Apparent increase chiefly due to errors in recording
  • True decrease chiefly due to lack of segregation at source and high moisture content of waste stream and inadequate training, also electrical and mechanical failures
  • Apparent decrease chiefly due to apathy and lack of supervision
  • Check recording procedures in the Resource Recovery Centre
  • Train and re-train personnel and 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

  1. Machinery breakdown can show a lower than actual re-sorting rate as the material re-sorted cannot be accounted for by weighment.
  2. Single special streams of certain material can inflate the re-sorting rate.
  3. Special circumstances, public holidays in particular, interfere with the observations.
