Bio-Spreading - Disposing of Biosolids


Nelson Marlborough Waste, through it’s Astro Bio-Spreading company, specialises in the collection and disposal of biosolids.


Astro Bio-Spreading disposes of bio-solids in an environmentally beneficial manner that is eco-friendly and economically productive. We disperse treated biosolids among the pine trees on Rabbit Island.

This has three benefits:

  1. The trees grow quicker and bigger;
  2. Disposes of a waste product in a way that is environmentally sustainable and;
  3. Is cost effective.

NMWaste has invested in purpose built, leading edge plant for the collection and disposal of biosolids.

Astro Bio-Spreading is the largest, most experienced biosolids disposal company in New Zealand, disposing more than 32,000 tonnes per annum.
