waste not WANT NOT

Earthmovers & Excavators - - New Machinery Review - Words and im­ages: Ran­dall John­ston

This fast-paced south-east Queens­land re­cy­cling and reveg­e­ta­tion com­pany has re­cently in­vested in a new Hyundai HL760-9 wheel loader to as­sist with load­ing waste into its screen­ing ma­chines for pro­cess­ing into com­post among other tasks. Now com­ple­ment­ing a small ar­se­nal of the lat­est ma­chin­ery, NuGrow’s new­est ad­di­tion is earn­ing its keep

NuGrow is a soil re­ju­ve­na­tion spe­cial­ist and coun­cil trucks con­tin­u­ally stream into the busy Swan­bank waste treat­ment and re­cy­cling fa­cil­ity, es­sen­tially pro­vid­ing fresh ‘fuel’ for the busi­ness which pro­duces huge amounts of com­post from waste, which is then made avail­able to land­scap­ers, mu­nic­i­pal coun­cils and pri­vate con­trac­tors.

While the com­pany has five waste treat­ment fa­cil­i­ties now, it all started with a smaller site over the road from where Ja­cob Wilson and his team now op­er­ate at Swan­bank – which is about 20 min­utes’ drive from Ip­swich on the out­skirts of Bris­bane – some 15 years ago.

“We moved to this site for the op­por­tu­nity to ex­pand, so we took over from an­other op­er­a­tor and took over the li­cens­ing that went with that,” Ja­cob says.

Af­ter snap­ping up more land ad­ja­cent to the orig­i­nal site, suc­cess came quickly and so an­other three sites were pur­chased, first at Grace­mere (near Rock­hamp­ton), fol­lowed by Roma and Ko­gan; giv­ing NuGrow ma­jor cov­er­age across Queens­land.

“It was a ma­jor op­por­tu­nity to pro­vide waste man­age­ment ser­vices to con­trac­tors work­ing on all the new oil and gas and min­ing de­vel­op­ments that were ramp­ing in cen­tral Queens­land at the time, which gave NuGrow a chance to es­tab­lish it­self in Grace­mere with the pro­cess­ing of re­us­able min­ing waste.”

“We start early at 6am and go right through to 5pm. We start the day with safety checks, be­fore we get stuck into the work and fin­ish the day with safety checks and pre­par­ing for to­mor­row’s ef­forts.

“Safety is key for us and that’s also a big part of why we do in­vest in new ma­chines, with the lat­est tech­nol­ogy to keep ev­ery­one safe on­site.

“This is one of the waste man­age­ment sites that pro­duce prod­ucts that are be­ing used for the Toowoomba Second Range Cross­ing project.

“Two prod­ucts that we cre­ate on­site are Hy­dro­gan­ics which is com­posted ma­te­rial

Safety is key for us and that’s also a big part of why we do in­vest in new ma­chines

in hy­draulic form and Grow­gan­ics ready for pneu­matic ap­pli­ca­tion of com­post blan­kets.

“The ma­jor­ity of prod­uct we make at this fa­cil­ity is com­post con­firm­ing for use in our Aus­tralian Stan­dard AS4454 and AS4419 prod­ucts for our in­stal­la­tion busi­ness Land­scape Ex­press.”

Ja­cob has ex­panded the ma­chin­ery fleet from two front-end load­ers and a dump truck 15 years back to two 30-tonne ex­ca­va­tors, four front end load­ers, three dump trucks and two screen­ing plants now.

“Were so busy we don’t of­ten get time to think about it but we have grown enor­mously in that time,” he says.

“A new waste levy is be­ing in­tro­duced in Queens­land and the re­sult of that will be more solid or­ganic waste for re­cy­cling rather than landfill and we are ex­pect­ing to see a lot of growth from that.”

“We are an en­vi­ron­men­tal com­pany so we like to have new ma­chin­ery, with the lat­est emis­sions stan­dards wher­ever pos­si­ble.

“It’s not al­ways an op­tion, but where we can we try to pro­cure ma­chines that are Tier 3 or Tier 4.”

NuGrow al­ready has three Hyundai HL770-9 wheel load­ers at the Swan­bank site, that have been in­tro­duced to replace their fleet of older Kawasaki ones and has just taken de­liv­ery of a brand-new HL7609 loader, which is just a touch smaller and more ver­sa­tile than the HL770-9.

“If it can op­er­ate more ef­fi­ciently then that’s less diesel and fewer man hours and, for us, re­duc­ing that car­bon pro­file is key.”

“Some of the tasks we use the wheel load­ers for are pretty tough, were run­ning them at a high RPM, es­pe­cially when were

man­u­ally mix­ing the solid or­ganic waste, so they need to have lots of grunt and be able to han­dle that kind of op­er­a­tion.”

“We need to be sure that the ma­chines that we buy will last in the fi­nanc­ing time frame that we set out and that what they de­liver on day one is what they de­liver on day 1000.

“We are very happy with our de­ci­sion at this point, we’ve taken de­liv­ery of a few ma­chines now and we’ve got more on the way.”

The or­gan­i­sa­tion also has a Hyundai R290LC-9 ex­ca­va­tor on or­der with the

Porter Group, which will also be put to work at Swan­bank.

Ja­cob and his team of op­er­a­tors are ea­gerly await­ing its ar­rival and says it’s built tough to en­dure the rugged, dusty and steamy en­vi­ron­ment of their waste re­cy­cling site.

This ex­ca­va­tor also packs a Cum­mins six-cylin­der turbo en­gine that has been de­signed to al­low in­creased air­flow and more evenly dis­persed fuel, which results in in­creased power, im­proved tran­sient re­sponse and re­duced fuel use.

Both the HL760-9 and HL770-9 wheel load­ers are Tier 3 and so hit the mark in re­gard to re­in­forc­ing NuGrow’s all-im­por­tant sus­tain­abil­ity pro­file.

Key fea­tures of the HL760-9 in­clude a

Tier 3 Cum­mins QSB 6.7-litre en­gine, ZF full au­to­matic trans­mis­sion with four modes (man­ual, light, nor­mal, heavy).

The front and rear axles have lim­ited slip dif­fer­en­tial for ex­cel­lent trac­tion even on tricky ter­rain.

The hy­draulic sys­tem util­i­ties a vari­able dis­place­ment pump and an im­proved cool­ing sys­tem. The front win­dow has 17 per cent more glass than the pre­vi­ous se­ries of Hyundai wheel load­ers for bet­ter vis­i­bil­ity – and re­versible, hy­draulic driven cool­ing fan al­lows for re­duced fuel con­sump­tion and less op­er­at­ing noise.

Ja­cob is keen to see if even fur­ther ef­fi­cien­cies and ben­e­fits can be gained in go­ing for this even smaller 17.9-tonne Hyundai wheel loader in terms of econ­omy, ma­noeu­vra­bil­ity, and fuel con­sump­tion.

“Emis­sions stan­dards are re­ally im­por­tant when you’re work­ing with lo­cal gov­ern­ment, but there are a lot of other con­sid­er­a­tions when in­vest­ing in new ma­chin­ery,” Ja­cob ex­plains.

“There are two parts to it for us; value for money on the ini­tial cap­i­tal in­vest­ment and the af­ter sales ser­vice that Porter Group pro­vide is vi­tal to us.

“They are great to work with. They al­low you to trial the ma­chines on­site to see how they work for your spe­cific pur­pose and make cus­tom ad­just­ments if they are needed.

“We want to be cov­ered for ev­ery­thing in terms of after­sales ser­vice when we pur­chase a new ma­chine, so that’s very im­por­tant to us.

“We’re al­ways re­view­ing our prac­tices and part of that is in­ves­ti­gat­ing whether the ma­chine we are cur­rently us­ing is the best that we can use for that ap­pli­ca­tion,” Ja­cob con­cludes.
