Solid Waste Indicators (what we measure)
Waste is generated as part of everyday living when people throw things away that they no longer require. Matamata-Piako is responsible for promoting effective and efficient waste management and waste reduction practices within the district. Refuse collection services are provided to approximately 8,500 households and 800 commercial properties throughout the district.
Within Matamata-Piako, Council has three refuse transfer stations, located at Waihou, Morrinsville and Matamata. Each is adjacent to closed, former landfills, which are managed to reduce unfavourable effects on the environment. Waste from the transfer stations is transported out of the district to a privately owned landfill at Tirohia, south of Paeroa. Compliance of the district’s landfills with their respective resource consent conditions is monitored regularly. Council monitors the amount and quality of leachate from the landfills to nearby surface water bodies, both up and downstream of the landfill location. Council also monitors several sampling bores near the landfills. The groundwater quality at the sampling sites has been good–satisfactory since 2000. Council’s sampling sites achieved a compliance rate of 100 percent with Environment Waikato’s Standards during 2009/10. In 2010/11 the Waihou Refuse Dump and Matamata Landfill had high levels of compliance with their resource consent conditions. The Morrinsville Landfill had partial non compliance, due to monitoring not being undertaken at the agreed intervals, and some monitoring results not being provided. However, there were no environmental concerns: there was no damage in need of urgent attention, and the quality and quantity of leachate pumped from the landfill had remained consistent. In 2012/13 to 2015/16 there was 100% compliance.
There were no reported incidents or spills involving hazardous waste in the district during the 2006/07 - 2009/10 period or in 2011/12. In both the 2010/11 and 2012/13 years there was one spillage of septage on to a roadway. There were no reported incidents from 2013/14 to 2015/16.
Quantity of Waste Generated and Recycled
The following graphs show how much waste is being disposed of to transfer stations in our district and how much of this waste is being recycled/composted.
Overall there has been a general decrease in the amount of waste being disposed of at the waste transfer stations between 2006/07 and 2014/15. In 2015/16, the volume of waste increased slightly. The decline beginning in 2011/12 was due to the loss of the Council’s largest private customer that used the Council’s transfer stations to dispose of waste; however, this waste was still sent to landfill.
The percentage of our district’s waste being recycled or composted has increased steadily over the last 5 years. However the graph above detailing the quantity of waste recycled varies from year to year. This is due to variation in the quantity of green waste being composted.
