Trial to cut odour prob­lem

Cockburn Gazette - - NEWS - Jes­sica Nico

COCK­BURN Ce­ment is seek­ing governmental ap­proval to run a six-month trial aimed at re­duc­ing odours re­leased in the lime pro­duc­tion process.

The com­pany has asked the Depart­ment of Wa­ter and En­vi­ron­men­tal Reg­u­la­tion to start the three-stage odour neu­tral­is­ing trial in De­cem­ber.

Cock­burn Ce­ment ce­ment and lime ex­ec­u­tive gen­eral man­ager Brad Lem­mon said the trial would in­volve spray­ing odour neu­traliser Aire­ac­tor OWD into the emis­sion stream af­ter it had gone through pol­lu­tion con­trol equip­ment but be­fore it left the two op­er­a­tional stacks.

He said the aim was for the droplets to block the smell and im­prove amenity for nearby res­i­dents.

“As part of our odour man­age­ment plan we are con­tin­u­ing to de­vote con­sid­er­able ef­fort to de­ter­mine the emis­sions source, pro­file and com­pounds for odour that may be emit­ted from our lime kilns,” he said.

“We want to ob­tain a con­clu­sive un­der­stand­ing of the cause of odour so we can adopt spe­cific and tar­geted ac­tions to re­duce it.

“The neu­traliser trial ap­proaches the is­sue from a new per­spec­tive and will re­duce amenity im­pact on res­i­dents while we ad­dress the source of odour.”

Mr Lem­mon said the trial would ad­dress only odour emit­ted as part of the lime pro­duc­tion process and res­i­dents might still no­tice smells cre­ated by other in­dus­trial, waste or agri­cul­tural ac­tiv­i­ties.

The re­sults of the trial are ex­pected to be re­leased in the sec­ond half of 2019.
