Eligible container factors are state-wide averages of the number of eligible containers in each kilogram of a material type (e.g. glass or PET). They are used to calculate how much a MRF operator can claim when the MRF operator uses the ‘weight’ method.

We calculate these factors using sampling data collected from MRFs and kerbside audits. Eligible container factors are published quarterly

Q1 FY26 (Jul-Sep 2025)

Material	Factor	SE	RSE	LB	UB
Aluminium	50.04	1.32	2.64	47.45	52.64
Glass	0.67	0.06	0.09	0.55	0.79
HDPE	0.37	0.06	15.98	0.26	0.49
PET	15.64	1.25	8.01	13.18	18.09
Mixed Comb	3.09	0.13	4.2	2.83	3.34
Mixed Seg	0.65	0.08	11.98	0.5	0.81
Visy Blend 1	4.94	0.17	3.37	4.61	5.27
Visy Blend 2	1.04	0.14	13.86	0.76	1.33
Interim BCS Glass	1.71	N/A	N/A	N/A	N/A
Estimates are pre-stratified.
SE = Standard Error.
RSE = Relative Standard Error SE as a percent of the factor
LB, UB = 95% lower and upper bound of the factor
Interim BCS Glass was not included in this quarter's update and the factor remains unchanged from the previous quarter.

We calculate the eligible container factor for each output material in accordance with the sampling plan approved by the ACT Waste Manager and the ACT Eligible Container Factor Methodology (.pdf, 268kb)

Q4 (Apr-Jun) 2025

Material	Factor (eligible ct/kg)
Aluminium	54.19
Single plastics^*	3.77
Glass	0.78
The single plastics factor applies to all HDPE, PET, and mixed plastics deliveries. The April–June 2025 (Q4 FY25) factors will be applied across the next four quarters, covering Q1 to Q3 of FY26
