Recommendation

RWMAC 04.06.2015 Agenda Item. 10.4

That Councillor Heenan be appointed chair of the Regional Waste Management Advisory Committee.

5.2 Recycling.• Discussion ensued regarding the recycling figures provided (refer to attached

report)• Mayor Ryan and the Committee does not support burning any further mattresses• Reinier advised that best way to recycle is to shred the mattresses by bring a

contractor in with a large shredding machine twice a year.• It costs roughly $30k for the mattresses to be shredded however the machine

can shred other item so would use to shred other items to save costs.• Council cannot stockpile due to the health risk with vermin nesting inside.• Shredding is the best way as the metal gets tangled and cannot be baled and

does the same if we decanter them. .• Discussion ensued regarding cost of shredding machine• What is Darwin currently doing? Hayley and Reinier are unsure and will contact

Darwin Council for further information.ActionInvestigate what Darwin Council does with its mattresses, research the market for an outlet for shredded items and provide costings for Council to purchase machine and what saving it could make.

5.2.1 Paper Baler• Hayley has done research on balers and report submitted to Council which was

approved - Resolution number 18243.• Balers can take both paper and cardboard however would be better separated• Looking at not charging general public for paper and cardboard recycling

however if mixed in load then will be charges• Cleanaway and ASTC looking at working together - Cleanaway at present pay

$60 a ton and generate 400 tonnes per year• Maybe possible grant funding - Hayley to investigate - Grant application has

been submitted and Council has been successful.• Concerned with how much paper/cardboard are already in our waste stream• Would need drop off bins somewhere - Greg advised that the Depot would be a

good location• Hayley advised will also take plastics like yoghurt pots and milk bottles.• Andrew Broffman has been engaged to provide a master plan• Fire hazard report being conducted with fire alarm to be installed once built• CCTV to be installed as well once shed is built

5.3 Liquid Waste• In every other Municipality in Australia, it would appear the water authority is

responsible for liquid waste (grease arrester water) except Alice Springs• Grease arrester from restaurants where the water can flow down drain but

grease is trapped in the arrester.• For the last 30 years we have dug a hole at the landfill waited for the water to

evaporate, scrapped off the slug and then buried. ERA came back to Council few months ago and stated that the process was illegal and Council should stop

RWMAC 04.06.2015 Agenda Item. 10.4

doing that - Greg advised them we could not until Power Water puts a processing plant on site.

• Reason Council still does this is because Power Water do not have process plant and the small family run restaurant would have to pay $2,000 per month to dispose of their product via freight to either Darwin or Adelaide

• EPA and Power Water have stated that it is the owner of the premises that is responsible for disposal - Council has stated to both parties that if Council stop’s the service they can deal with the media implications.

• Councillor Kudrenko asked what kind of cost would we be looking at - Greg advised that it would be an approx. $2.5m project for the plant and operation.

• It came about due to a Territory legislation change that the product has to be processed

• All we keep getting from Power Water is “it is the generator of the waste who is responsible”

• Peter Bannister has advised that what Council is currently doing is fine and EPA has approved but it is not EPA’s preferred way of disposal.

• Council has started building the pits 30mtr by 10mtr- 2 soaking pits lined with clay then has a layer of plastic then another layer of clay so nothing can seep through, let it evaporate off, scrap off sludge and then bury sludge.

• Ponds are built and now in use• No further problems forecast once EPA inspect and sign off• Committee members to look over site once master plan is completed

5.4 CCTV Camera• Greg has asked landfill to obtain quotations for an integrated security camera

from the tip shop to the weighbridge and to out the back where the glass crusher is.

• CCTV was installed a few years ago following a break in at the weighbridge and the number of cameras was questioned with the Elected Members. Greg advised that they are still installed and working but problem we face is out the back (glass crusher area and compound where the vehicles are stored).

• Will be hooked up to power from out the back office and portable, this is pending quotations coming in, Reinier thinks it will be roughly $ 8-9K

• Still investigating optionsActionSecurity Ranger (Chris Clark) to contact Councillor Steve Brown regarding CCTVcamera system he uses.

5.5 Up Cycling Show/Event• Caterpillar Kids event this was a proposed event to be held at the WMF• Advised due to no public liability cannot be held at WMF so will be relocated to

the Watertank Cafe• Grant funding for 4 workshops and 1 show

ActionHayley to chase Community Development Unit (Mitch Cameron) regardingCommunity grant funding acquittal and follow up report

TO: REGIONAL WASTE MANAGEMENT ADVISORY COMMITTEE

SUBJECT: REPORT FOR THE REGIONAL WASTE MANAGEMENT ADVISORYCOMMITTEE FOR THE MONTH OF JUNE MAY 2015

AUTHOR: MANAGER REGIONAL WASTE MANAGEMENT FACILITY - REINIERLAAN

1. Mattresses

Mattresses are a problem waste item for most landfills. The springs of the mattress has the tendency to get tangled under compactor’s carriage and strap the wire around either around the axle and wheel drum or hydraulics. The mattresses also take up a lot of space from an environmental point of view.

Since last year the mattresses has been decant and recycled by the work crew. After the mattress and or coaches are decanted the steel and wood frame is transported to the steel and wood stock pile for further baling later by contractors. At the Regional Waste Management Facility (RWMF) approximately 90% of the mattresses are recycled. Some of the mattresses are taken straight to the mattress stockpile due to OHS issues.

The RWMF had tested a few recycling methods for mattresses (1) burning of mattresses (due to OHS issues), (2) decanting of mattresses by the work crew, (3) shredding of mattresses by contractors. All these methods required the baling of the metal springs at the end of the recycling processes by a contractor. The shredding is currently the most work able solution as the metal recycling contractors do not bale metal mattresses springs.

Z,RWMF expects to collect 800 mattresses and coaches in the 2015 financial year. The monthly average is 69 mattresses. The current fees and charges for the disposal of mattresses are $32.50 for a double mattress and $15.00 for a single mattress. The shredding cost for mattresses is $50 per mattresses by the contractor. The total cost for shredding mattresses is estimated between $30,000.00 to $40,000 per year with an estimated income from fees and charge of $25,000.00 at the weighbridge.

The negative aspect of shredding mattresses may be the big time lapse between contractors, therefore mattresses numbers may built up to unsustainable levels and may require burning due to OHS issue associated.

2. Recording of Recycling Data:

The standard process at the RWMF is that the recycling data off the big stockpile (concrete, metal, mulch and pallets), glass, and cardboard and e- waste is recorded when the items have left the RWMF across the weighbridge.

However the data for the Rediscovery Shop (e.g. building goods, drop off zone and household goods) may not reflects the total tons of second hand goods that already have left the RWMF, but indicate that it may be eventually sold or returned to the landfill. The data reflects the recycling contribution of the work crew and residents.

Also the recycled scrap mattresses springs is not reflected in the recycled scrap metal data weight as the contractor could not bale it. On estimation the recycled mattress springs contribution between 1 to 2% of the total recycled scrap metal. The recycled mattresses data is capture to reflect the work crew contribution towards recycling.

The data for mattresses and the Rediscovery Shop (e.g. building goods, drop off zone and household goods) reflects the recycling efforts, but there is a time lag between the data being recorded and goods being sold.

3. Cost and Benefit Analyses of the Rediscovery shop

The Sales data of the Rediscovery Centre was analysed to determine the profit or loss figures for the 2014/2015 financial year.

The expenditure at the Rediscovery Centre is made up of staff cost (Customer service at point of sale plus feed stock collection cost at landfill).

The expenditure calculation focus mainly on staff cost, which is the mayor contributor to cost. The income at the Rediscovery Centre is made up of Sales plus space saved at the landfill. The space saved at the landfill is the estimated the 200 tons sold as second hand goods through the Rediscovery shop.

Profit and Loss:

Profit/loss: Income -Expenditure

Profit/ loss: $186,000.00 (Table 5) - $166,348.00 (Table 6) = $19,652.00.

The estimated profit for the Rediscovery Shop (2014/2015) is an estimated $19,652.00.

Cost variables:

The annual Staff cost for collection of feed stock ($34,024.64) from the landfill and staff cost (serving customers) at the Rediscovery Centre ($132,324.19) amounts to $166,348.00.

The feed stock figure is based on two work crew members and a staff member collecting stock for 4 hours a day for 5 days a week. The customer service figure is based on a minimum of one full time staff member serving customers 7 days a week.

The total feed stock collected at the Rediscovery Centre reduces the landfill volume by 400 cubic meters with an estimated value of $26,000.00 at $65.00 per cubic meters. The income for the Rediscovery Centre includes space saved ($26,000.00) and an estimated annual revenue ($160,000.00), which amounts to $186,000.00.

4. River sand road project.

These projects investigate the use of river sand to reduce the water usage for dust control at the RWMF.

A road area was tested in front of the old public bay. The river sand was placed on a 20 m road strip 100 mm deep with river sand collected from the Todd River.

The procedure for application was that the river sand was mix with water and applied with a road-grader 100 mm thick. The thickness of the river sand was determined by the existing hardened/capped road base to allow the moisture to penetrate deep enough.

The observation made during testing was that the river sand moved down the gradient off any steep inclines and settled in the flat area influenced by the low binding (clay) property of the river sand.

Portable water frequency applied by the water truck was increased from 3 to 5 times a day to maintain the test area in a good condition,. The daily water usage therefore increased from 6000 litters to 10000 litres.

The RWMF’s Supervisor and managers visited Macdonnell caravan park Alice springs the test site at his workshop area and the main difference that was observed.

• The workshop carry smaller commercial truck then the test road at the RWMF

• The workshop lower truck traffic with low tonnage. Approximately 50,000 contractors’ transactions pass through the weighbridge.

e Road base at the workshop had a clay soil mix.
