Convenient community composting

Bike-powered community composting

No space or time to compost, but don’t want to send your scraps to landfill?

We can collect your food scraps every week and turn them into beautiful compost to grow more food at our urban farm.

Why compost?

Between 30% and 50% of Auckland’s kerbside waste is food scraps.

When organic material is buried in landfill, it breaks down anaerobically (without oxygen), producing harmful methane emissions, and toxic leachate.

At the same time, our soils are being rapidly degraded across the globe, and are in desperate need of the fertility that we’re currently sending to the landfill.

Our Impact

By diverting our community’s food scraps from landfill, we are converting a waste problem into a valuable resource that has significant benefits for our food security, soil health, and in mitigating climate change.

Compost builds the fertility of our soils, allowing us to grow nutrient-dense organic food that is naturally strong and resistant to pests, without the use of artificial fertilisers or pesticides. Compost also adds important structure to our soil, increasing water retention, reducing erosion, and allowing plants to sequester carbon from the atmosphere and store it in the soil.

“Since joining Soil Factory, my young children have taken a huge interest in composting and reducing waste to landfill.

We’ve been on visits to Kelmarna Gardens so that they can see where their compost ends up - and the team at the Gardens have been amazing at educating and feeding my children’s enthusiasm for looking after their environment.

It’s been amazing how little landfill we send out in the weekly pick up now.”
