Hungry Worms
Our Process

Food waste to natural fertiliser.
Saving the environment one bite at a time.

Every kilogram of food waste we collect avoids more than 2.5 kg of greenhouse gas. Here's exactly how that happens.

Our recycling process

Step 1

Waste Collection

We collect food and green waste from your site on a scheduled basis. Bins are supplied, maintained, and swapped out at every visit — no mess, no hassle for your team.

Step 2

Natural Breakdown

Your waste enters our vermiculture process. Thousands of compost worms convert organic material into premium vermicast — no toxic byproducts, no methane, just nutrition-dense soil amendment.

Step 3

Industrial Composting

Industrial composting machinery accelerates the process for larger volumes, achieving maximum diversion from landfill and cutting the timeline from months to weeks.

Step 4

Going Full Circle

The finished worm castings and compost become the foundation of Uncle Bob's regenerative garden products — sold back to you, your customers, and NZ gardeners. Your waste returns as a premium resource.

Behind the scenes

See the process in action.

Watch our co-founder Mark walk through the composting machine and show what fully processed food waste actually looks like — rich, clean, nutrient-dense compost ready to begin its second life as premium, 100% natural fertiliser.

  • Industrial composting, up close
  • From raw food scraps to finished vermicast
  • No landfill, no methane, no waste

The science

Why food waste matters

The science behind our impact claims — sourced and cited.

~4%
of total global GHG emissions

come from food and organic waste. It's one of the most impactful — and most overlooked — emission sources.

>2.5 kg
CO₂e per kg of food waste

For every kilogram of food waste sent to landfill, more than 2.5 kg of greenhouse gas is emitted. Our collection directly prevents this.

25×
more potent than CO₂

Methane — the gas produced when food rots in landfill — is 25 times more potent than carbon dioxide as a greenhouse gas. Diverting your waste matters.
