3 Background The Bunbury-Harvey Regional Council commissioned a very ambitious plan in 2012 to construct and operate a regional compost facility to convert municipal organic waste into a high grade soil amendment improving the carbon depleted soils of the local area and reducing the amount of landfill gases being produced at Stanley Road Waste Facility. In June 2013 the City of Bunbury being the first of the Councils in the region to implement the three bin service commenced disposing of organics at the newly commissioned facility. The Shire of Capel commenced there organics service a couple of months later with the Shire of Donnybrook-Balingup twelve months later and just recently the Shire of Collie has commenced. The four Councils have a combined population of 64,117 residents and deliver an estimated 11,726 tonne of organics from the municipal organics waste collection and a further 4,092 tonne of green waste from verge side bi-annual collection and waste transfer stations per year. It would be anticipated that in the future to see the remaining Councils in the Wellington Group of Councils to commence with a municipal organics collection and the possibility of expanding the service outside of the Wellington Group to Councils within the South West and Peel areas.

4 Background The organic waste recycling includes all food scraps, grass clippings, leaves, soiled paper, excess cardboard, pruning's and small non-treated timber offcuts. The organic recycling service has put the Councils in a position of best practice in waste management on a State, National and International level, with the City of Bunbury achieving 65% diversion rate.

5 Background Organics bin rollout commenced on the 27 May 2013 and was completed late June 2013, prior to the commencement of the new financial year. Waste bins have been fitted with new red top lid as per Australian Standards. New collection trucks have been delivered with graphics depicting the new three bin service. Bin Size Options for Residents Organic Recyclables - 140L or 240L mobile garbage bin with lime green lid and body serviced on a weekly collection. Dry Recyclables - 140L, 240L or 360L mobile garbage bin with yellow lid serviced on a fortnightly collection. Residential Refuse (Garbage) - 140L or 240L mobile garbage bin with red lid serviced on a fortnightly collection on opposite week to dry recyclables. Organic Recycling is offered as a new service to Commercial Rate Payers, targeting restaurants and food processors.

6 Organic Processing Facility A purpose built processing facility constructed at the Shire of Dardanup, Banksia Road Waste Management Facility. Less than 5% contamination desired. Organic collection trucks weighed then offload the organics on a purpose-built hard stand. Organics mixed with mulch and stockpiled (stage 0) on a mobile aerator floor (MAF) unit for up to four weeks. Organics turned and relocated to another MAF unit for a further four week period (stage 1). Turning and relocating a further four times (stage 2,3,4 and stage 5) at four week intervals Monitoring of temperature and moisture levels on all stages. Adding water via sprinkler to increase moisture and increased running time of aerators when moisture levels are too high to ensure optimal composting conditions. After the twenty week 5-stage process the organics composting is completed to Australian Standards and is then put through a 50mm screening plant. The bulk particles (51mm and up) are sent to landfill as the majority of contamination is removed at this point. Compost is relocated to the screening area and put through a 10mm- screening plant. Fines (10mm) are stockpiled ready for bulk sale. The mediums (11mm to 50mm) are utilised for rehabilitation purposes at landfill. Once a batch has undergone secondary screening, samples are taken and sent to an accredited laboratory to be tested against the physical and chemical requirements as detailed in AS

11 Future Expansion and Upgrades Currently the Wellington Organic Processing facility is on leased land and in the future will require relocating to Council owned land. The preferred new site is the Stanley Road Waste Facility Wellesley with the approval process and new design incorporating best practices commencing shortly. An expansion of the facility will be included in the new design to accommodate all Councils with-in the Wellington Group of Councils. A pre-sorting facility is also being considered for future upgrades, the pre-sorting facility will enable the 2 to 5% contamination to be removed and all the organics to be mulched prior to being put on the aerated windrows. This process will increase our 10mm compost production by a further 15 to 20%.

12 Results The BHRC have an agreement with Intuit Earth to supply 3,000 tonnes per annum of 10mm compost, Intuit Earth currently have markets for the compost to various horticulture industries throughout Western Australia. The BHRC have established markets for raw and pasteurised mulch including supply to the Main Road Department and the general public. Amendments are add to the compost during processing to produce a high grade fertiliser meeting the industries requirements. Australian Certified Organic has been achieved for all compost produced at the facility. The compost helps to sustainably improve food production in the local area and also helps to improve the environment with the reduction of landfill gases and leachate from organics not being put into landfills. Additionally it gives local farmers access to an organic fertilizer option other than the traditional synthetic fertilizers option that do major damage to the local water ways and environment. At source separation works and it helps to build a partnership between the residents and Council, with most residents wanting to do their bit to improve the environment. The organic waste is a valuable resource and should be treated as such and not lost forever in landfill or a waste to energy facility.
