Eco-clever plan for restaurants
FOOD retailers and restaurants across Cockburn have been urged to join a sustainability and eco-friendly commercial food waste trial.
The City of Cockburn trial is a partnership with Richgro that will process the food waste into a high-quality biofertiliser at its anaerobic digestion plant in Jandakot.
Excess electricity via methane will also be captured and fed back into the grid.
Cockburn waste education co-ordinator Clare Courtauld said up to 60 business could be accepted in the free three-month trial, depending on the waste type generated.
“Food waste is a nutrientrich resource that if diverted from landfill, where its decomposition creates potent greenhouse gases, can be used to produce valuable biogas for electricity generation, compost and soil conditioners,” Ms Courtauld said.
“The trial will help the City determine the benefits of a commercial food waste collection service to reduce costs and improve resource recovery levels.
“Results will be analysed and reported to council for a decision on future implementation if benefits of the trial can be proven.”
Twenty local businesses have already signed up for weekly collections until the beginning of November and if the trial proves successful, the partnership could be adopted permanently.
Richgro chief executive Tim Richards said the plant’s capacity to process 137 tonnes of commercial and industrial organic waste per day, or 50,000 tonnes per year, had to date enabled more than 300,000 tonnes of waste to be diverted from landfill.
“Now that we have two 1.5MW generators, we can generate a maximum of 57,600KW per day, helping us to power the equivalent of 3200 homes,” Mr Richards said. “By producing an average 60,000 litres of biofertiliser per day, we are powering homes right here in the City of Cockburn as well as the Richgro site.”
Cockburn businesses that take part will be provided with training, 120 or 240 litre food waste bins and compostable bin liners.
