A cutting edge development in the fight for sustainability in the food and fibre sector.

New Zealand based company Environmental Decontamination has cracked a way to grind mussel shells into calcium carbonate.

It's a product used in paper, concrete and paint.

New Zealand currently processes around 100,000 tonnes of green-lipped mussels, which generates around 55,000 tonnes of waste per year.

Project lead, Kapish Gobindlal told Kate Hawkesby the new technology offers a step towards a more sustainable future for the food sector.

He says the very fine powder can now be used in the construction industry and in commercial goods.
