Petuna is set to trial a world-first waste capture innovation in Macquarie Harbour, which has the capacity to remove around 75 per cent of waste produced by salmon farms from the marine environment.
The innovation, developed by Tassal employees, captures 65 – 87 per cent of solid waste in liners below the marine farms, which may be reused as a nutrient rich agricultural fertiliser in the future.
Once the solids are separated, the waste water collected – which makes up around 95 per cent of the overall waste – will be safely removed, disinfected and treated in Devonport through a new agreement between Tassal and TasWater.
Petuna Acting CEO David Wood said the company had been monitoring the waste capture program since its inception, to determine whether it was an effective and viable environmental solution.
“We’re now in the final stages of negotiating a commercial arrangement with Tassal to allow us to trial the system in selected marine farms in Macquarie Harbour,” Mr Wood said.
“This is an exciting industry innovation, which has so far exceeded expectations, proving a vital tool in supporting sustainable farming in the Harbour into the future.
“Petuna understands and accepts its social obligation to help maintain the integrity of the Harbour environment. It is also in our commercial best interest to do so.”
