The waste process

Finding the right home

While APL is working hard to build a more circular business, not every material is able to be repurposed. That’s why we’re working closely with Enviro NZ, a materials management and resource recovery company.

The aim is to reduce the amount of waste we send to landfill by 50% through circular practices, recycling and diverting food waste.

All of our recycling goes to the Hamilton Materials Recycling Facility, a critical piece of Enviro NZ's nationwide infrastructure. At this facility, the paper, cardboard, grade 1, 2 and 5 plastics, tin and aluminium collected from roadside wheelie bins are sorted and separated with the help of optical sorting technology, imaging sensors, magnets and eddy currents.

World-class facilities

After diverting all food waste and recyclables, any remaining waste is then taken to Enviro NZ's Hampton Downs Resource and Energy Precinct facility, an 87 hectare class 1 site that serves the fast-growing regions of Waikato, Bay of Plenty and Auckland.

The site is consented to safely dispose of 30 million cubic metres of waste in its lifetime and, based on current volumes, it is not expected to reach capacity until sometime around 2055. When that time comes, the landfill will be covered in clay and can safely return to farmland. 

Just as APL is looking to turn its waste streams into revenue streams, Enviro NZ runs a ‘Gas to Energy-Recovery’ initiative at the Hampton Downs facility, where methane gas generated by the refuse waste is captured. The gas is then filtered and cleaned to  drive seven engines, which provide power for approximately 6000 households in the region. The facility has also scaled up its organics infrastructure to capture more food scraps and organic waste that might have otherwise ended up in landfill and turn it into nutrient-rich compost.

Moving forward

Through our partnership with Enviro NZ we undertake annual waste monitoring reviews, enabling us to assess current process and identify areas of opportunity, to further increase diversion from landfill by highlighting new diversion streams.
