About Fertify

Auckland Council are collecting food scraps on a weekly basis across mainland urban Auckland to reduce waste and create renewable resources. Your food scraps are turned into renewable energy and liquid fertiliser (Fertify), at Ecogas’ processing facility to grow more kai.


Fertify (also known as digestate), contains all the nutrients and minerals from food scraps. Applying Fertify is a great way to provide nutrients to your home garden. By using Fertify as a substitute or supplement to traditional fertilisers, you can return the nutrients from food waste back to the soil, and reduce greenhouse gas emissions.


Application Method

You can apply Fertify straight on your garden or lawn 3-4 times per year. It is best to apply Fertify evenly. To do this, you can pour Fertify into a watering can or dilute it (50/50) with water, then apply it to your garden or lawn.


Product Benefits

  • Recycling nutrients that would otherwise end up in landfill.

  • Unlike traditional fertiliser, the liquid fertiliser is not produced using fossil fuels, or mined, therefore reducing greenhouse gas emissions

  • 75% of the nitrogen is present as ammonia and is highly accessible for plants, compared to compost or farm effluent. This allows more precise application, better uptake of nutrients and reduces leaching

  • Locally produced in Aotearoa

  • Contains a full spectrum of nutrients and trace elements for conditioning of the soil

  • Contains residual carbon which helps soil retain water better and improve regeneration.


Product description

  • Black or dark brown with an earthy smell

  • pH 7.5-8

  • small portion of solids (<5%)

  • 0.4% Nitrogen, 0.01% Phosphorus, 0.1% Potassium, secondary nutrients (Magnesium, Calcium, Sodium and Sulphur), trace elements


Product safety and storage

Fertify is a natural product that has been made using your food scraps and then pasteurised for your safety. Any unused Fertify should be kept in a tightly sealed container.

Avoid direct contact with eyes or skin. Wash hands thoroughly after handling. If there is direct contact with eyes or skin, please wash immediately with water. If ingested orally, rinse mouth with water immediately. If unwell, seek medical advice.
