The Compost Co.

Bringing the compost to compostables

Join The Compost Co. team or donate today!

The Compost Co. is managed by the Waiheke Resource Trust, and funded by Auckland Waste Minimisation and Innovation Fund.

The Compost Co. is a local initiative led and guided by WRT. The project offers a food waste collection service to local restaurants and community groups. Compost Co. also collects and processes single use compostable packaging from coffee shops and zero waste events.

The project began in February 2018, and has grown into a sustainable business that can process over 20 tonnes of foodwaste a year. Compost Co. are committed to reducing waste from landfill, and thus offer the only commercial compostable packaging service on the Island.

If you are a business on Waiheke that is currently looking for waste solutions, please get in touch with prashanti@wrt.org.nz

BIO-ZYME is an environmentally and user-friendly cleaner, degreaser and deodorizer – a healthier and safer alternative to toxic cleaners, solvents, caustics and bleaches.
The concentrate is biogro certified, NZ made and enhances bacterial growth in your septic system. The “green Cleaner” can be used as a concentrate or diluted on any washable surface, floors, toilets, carpets and drains. Be kind to your waterways by maintaining a healthy septic system with BIO-ZYME. The product is available at the Sustainability Centre in 1Lrecycable bottles and refills thereof. A portion of the proceeds from Bio-Zyme is donated to The Compost Co.

Why is composting so important?

Commercial organic waste currently contributes a lot of compostable materials to landfill, with nearly 50% of Waiheke's compostable waste being sent to landfill. Once it is been buried it doesn’t compost down, instead it rots down anaerobically. This causes problems such as the release of methane gas, and the filtration of liquid from the food scraps, through the landfill, which has to then be collected and treated onsite to prevent contaminated leachate reaching and polluting our waterways. However, these issues can easily be reduced by making use of all food scraps and other organic material through composting.

Composting is easy! It takes very little time to compost your food scraps.

Composting is cheap. Apart from the initial investment in a composting bin, there are virtually no additional costs to composting.

Compost is a great way of adding nutrients to your soil. It can help produce higher yields of fruit, vegetables, and flowers. It can loosen clay soils, help sandy soils retain water, and it can suppress plant diseases and pests. It is capable of all this without containing petroleum-based compounds that most commercial fertilisers do.

Composting does not produce nasty smells or attract pests. Only composting that is done incorrectly produces a nasty smell or attracts mice and other pests. To avoid these problems simply make sure to add enough browns to your compost and keep dairy products and meats out of your compost pile. These can be put into a Bokashi bin instead!

Composting puts biomass back into the soil rather than taking it away. Soils are vital in carbon sequestration and water retention, with approximately 20% of global carbon being stored in soil.

Composting reduces the methane gas emissions from compostables in landfill. Methane is 23 times more damaging in the atmosphere than carbon dioxide, so reducing food scraps in landfill can help reduce the greenhouse effect and climate change.

The work of The Compost Co. is currently diverting roughly 400 kg of food scraps and other compostable materials, a week!

How The Compost Co. works:

  • Twice a week there is a collection service that collects 120l air tight food waste wheelie bins, plus other bins full of compostable packaging
  • All the compostable products are taken onsite to Te Motu Vineyard, our partner providing the land
  • Packaging gets shredded, food gets fermented or put raw into NZbox compost bins and mixed with different carbon ("brown") materials
  • The Hot compost is turned regularly while the Bokashi anaerobic compost stays cooler, allowing worms to populate and do their work
  • The Hot compost is important for the breakdown of PLA  and to kill any pathogens that may exist
  • The Bokashi compost is important for maintaining Carbon mass and nutrient value throughout decomposition

The Compost Co. welcomes volunteers to get involved with our composting sessions. Volunteers can get involved by helping to sort the compostable material, mixing the organic materials into the compost bins, turning the compost and by cleaning and maintaining the site.
