Waste

The City of Onkaparinga is committed to reducing the amount of waste that goes to landfill, from both domestic households and council operations. Since 2006 there has been a three bin collection system (general rubbish, recyclables, and green waste) in use to minimise waste and maximise reuse and recycling.

Waste to landfill

Total amount of waste to landfill was sourced from the City of Onkaparinga, Fleet and Waste (11). Per capita waste to landfill was determined using Australian Bureau of Statistics Estimated Resident Population by Local Government Area (9). The most recent data available for analysis was for the financial year 2014-15.

 

Data Analysis

In 2014-15 the amount of city-wide waste going to landfill was 37,880 tonnes and the amount of waste to landfill per capita was 224.4 kg (Figure 1).

In 2014-15 the total amount of city-wide waste diverted from landfill was 27,782 tonnes and the amount of waste diverted from landfill per capita was 164.6 kg (Figure 2). The total amount of waste diverted from landfill accounted for 42.3 per cent of all waste produced in the City of Onkaparinga in 2014-15. The majority of waste diverted from landfill was comprised of recyclables collected from kerbside (52.5 per cent), closely followed by green organic waste collected from kerbside (46.1 per cent) and a small amount of hard waste (1.4 per cent).

Trend Analysis

CWM waste trend analysis

Since the introduction of the yellow recyclables bin and the green organic waste bin in 2006, the volume of household waste to landfill has decreased (Figure 1). When compared with 2003-04, the amount of city-wide waste to landfill in 2014-15 decreased by 19.8 per cent, and the waste to landfill per capita decreased by over 28 per cent. However, as demonstrated in Figure 7, since the introduction of the three-bin collection in 2006-07, the city-wide amount of waste to landfill has slowly been increasing, such that when comparing 2006-07 with 2014-15 there was actually an 18 per cent increase in the amount of city-wide waste to landfill, and a 9 per cent increase in per capita waste to landfill.

Due to the introduction of the recycling process the amount of waste diverted from landfill over the past 10 years dramatically increased when compared with 2003-04, which was prior to the three-bin system (Figure 2). This improvement in waste diverted from landfill was largely due to the recovery of recyclable materials such as paper, glass, plastics and green organic waste. In 2014-15 the amount of city-wide waste diverted from landfill increased by more than three and half times (more than 250 per cent) when compared with 2003-04. Similarly, the waste per capita diverted from landfill also increased by more than 210 per cent.

It should be noted that while there was a sharp increase in the amount of city-wide and per capita waste diverted from landfill between 2003-04 and 2006-07 (185 per cent and 178 per cent, respectively) when the recyclable bins were first introduced, this rate has slowed dramatically in more recent years. The rate of increase in waste diverted from landfill between 2006-07 and 2014-15 has slowed to 23 per cent city-wide and 13 per cent per capita.

 

Policy Implications

The introduction of the kerbside three bin system in 2005 and 2006 resulted in a marked reduction in the amount of waste going to landfill. However since 2006 there has been a gradual increase in the total amount of waste going to landfill and also slight per capita increase. This indicates that there needs to be greater efforts in waste recycling to continue to reduce waste to landfill. Over recent years there has been significant investment in waste and recycling education programs and the draft Waste and Recycling Strategic Management Plan proposes to review our kerbside service arrangement in 2019/20.
