Eco-clever plan for restau­rants

Fremantle Gazette - - NEWS - Ben Smith

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.
