Smartsensor

smart-bins-pic

Smartsensor by Solar Bins Australia uses technology to help waste managers overcome environmental damage, poor user experience, and ever-increasing operational costs.

The company developed a sensor and software management platform that enables waste managers to gain a bird’s-eye view of their waste network, monitor the fullness of their rubbish bins and report clearly and accurately in real-time. The sensor device, which is attached to the inside of a rubbish bin or waste container, transmits data on the fullness of the bins, temperature of the container, the stability of the container and its location. This provides waste collection companies with an eye into each of their containers so they know exactly which bins are ready to be emptied and when.

The system includes a dedicated rubbish bin monitoring app and dashboard to map, monitor and maintain every bin and waste management asset deployed within the user’s region.

Using the power of ultrasonic sensors, 3G, LoRA or Sigfox communication, dynamic dashboards, fullness level alerts, routing and predictive collection, Smartsensor has been created to provide users with deep insights to every rubbish bin deployed in an area, town or city.

Australian landfill potential

landfill-pic

REMONDIS’ Roslyn Florie-George reflects on how legislation in Germany has reduced the nation’s reliance on landfill, and whether a similar landscape could work in Australia. 

In 1993, the German Government issued a directive banning all waste with an organic content of more than three per cent from being sent to landfill.

The objective was to promote resource recovery and pave the way for energy from waste projects across the nation. But despite the bold initiative it was not implemented properly, according to the European Environment Agency’s 2009 report: Diverting waste from landfill.

The report concludes that this was due to several loopholes regarding the processing of waste, including whether mechanical biological treatment (MBT) methods could be used to treat waste before landfilling. It was decided that incineration should be the main pre-treatment method, with MBT as an alternative. Eight years later in 2001, the government ruled to close the loopholes. As a result, the transition period was extended from eight to 12 years, with the final deadline scheduled for 1 June 2005.

The goal was to give the waste management industry enough time to establish the infrastructure needed to treat waste. This was particularly important in the federal states located in the former East Germany, which were adjusting to reunification.

REMONDIS’ National Tender/Bid Manager Roslyn Florie-George believes the industry was slow to move on the changes, taking advantage of the legislative loopholes in place.

But despite the industry’s delayed response, the legislation proved largely successful after the ban was finally introduced and the loopholes closed.

REMONDIS operates 21 landfills internationally, with 13 based in Germany. The landfill operations complement its recycling facility portfolio that comprises more than 800 waste management facilities internationally.

Roslyn says REMONDIS’ vast experience has allowed it to adapt to changes in legislation, including the benefits and limitations that landfill bans have placed on industry.

“After the directive was issued in Germany in 1993, industry did not respond as quickly as the German Government had anticipated,” Roslyn says.

“In 2004, Germany saw significant volumes of waste sent to landfill at cheap rates as the grace period drew to a close.

“After the ban was implemented in 2005, untreated baled waste was stockpiled, waiting for industry to build the necessary infrastructure to process it first. Many landfills were decommissioned after the ban because they could no longer accept untreated waste legally.”

A 2009 report by the UK think tank the Green Alliance developed for the UK Federal Government found Germany sent only one per cent of its waste to landfill after a ban was introduced, compared to 27 per cent beforehand. The result was accompanied by a nine per cent increase in incineration, which included energy to waste projects, and a 25 per cent increase in materials recovery.remondis-pic-2

Roslyn believes the strategic decision to ban organic waste from landfill means Germany’s landfills are as far as 20 years in front of Australia.

“Federal Government divisions have looked at landfill bans for specific waste streams in Australia, but none have been implemented at scale.

“We have predominantly relied on state-based landfill levies to influence the waste management practices of the generator and to divert significant tonnes from landfill,” Roslyn says.

Landfill levies are levies paid on all waste disposed of at licenced landfills, and are currently in place in New South Wales, Victoria, South Australia and Western Australia.

As a result of the ban, Kapiteltal Landfill in Kaiserslautern was decommissioned in 2006. REMEX (a REMONDIS subsidiary) was engaged post decommissioning to extend the landfill’s life by 35 years by building a new landfill on top of the old one.

By 2013, planning approval was granted for the “new on old” cell design and by 2016 it was re-opened to receive treated waste (mineral waste).

“It is an interesting example of new technology being employed in Germany that could be applied to landfilling in Australia,” Roslyn says.

“As land becomes scarcer and planning approvals difficult to obtain, extending the life of old landfills and old cells is an option worth exploring.”

Roslyn notes that Germany’s ban was also influenced by a lack of landfill space, whereas Australia has taken advantage of old quarries and mines created by Australia’s rich mineral wealth and mining activities over many decades.

Selecting the right portable generator

copco

Selecting the right portable generator can have a big impact on performance, reliability, serviceability and the residual value of the asset.

That’s according to Redstar Equipment’s General Manager of sales, Kevin Ennis, who explains that not doing your homework could end up costing you down the line in technical and maintenance issues.

A portable generator is a made up of a fixed speed diesel engine spinning an alternator (generator) at 1500 rpm. The alternator is configured to produce the type and voltage of electricity required. There are three different applications for portable generators – standby, prime fixed and prime mobile.

“A standby generator application is used when a mains power already exists and a generator is required to act only as back-up if there is a blackout. Subsequently, the generator will usually only run a handful of hours per year, if at all,” Kevin says.

“You should select a standby generator based on the quality of the brand, price, availability of parts and access to a local service agent.”

A prime fixed generator is used when the generator is the primary source of power and the generator will remain in one location for most of its life.

“In any prime (running) application, most of the cost of owning or renting a generator is fuel. The quality of the brand, size, fuel efficiency of the engine and access to parts and service is critical for prime fixed generators,” says Kevin.

“It is essential to consult a generator specialist to assist you in selecting this type of generator.”

“A good tip to save some costs is selecting a machine with a cheaper frame or canopy because the machine will not be moved around.”

A prime mobile generator is used when the generator is the sole source of power but it will also be moved from site to site regularly.

“Prime mobile generators are commonly used by construction and rental companies,” Kevin add.

“Quality of the brand, size and fuel efficiency of the engine is key to saving costs.”

“A robust build and canopy design is essential for the longevity of prime fixed mobile generators.”

Access to quality technical support and careful selection can significantly increase the life span of all portable generators.

Pronar mobile trommel screen

MPB_2055_w pracy_VI_2014 (7)

The first PRONAR MPB 20.55g (Tracked) Trommel has arrived into Australia and available through exclusive distributor Lincom Group.

The 20.55g features a 5.5m long X 2m diameter drum which allows for increased throughput. Lincom Group says the transport length of 10.7m, width of 2.8m and weight of approximately 20,000kg means the machine can be easily moved interstate.
Standard inclusions on the MPB 20.55g are the robust and long-lasting CAT engine, Clean-Fix system fitted to the engine radiator and hydraulic cooler, Danfoss hydraulic components and Lincoln central greasing system. The Clean-Fix system alters the blade angle of the cooling fan fitted to both the engine radiator and hydraulic cooler at set times. When the blade angle is altered, the air flow is reversed and any contamination, such as plastics, grasses and dust drawn into the radiator/cooler, is blown away. This results in the engine and hydraulic cooling systems running at lower temperatures, and in the long term, gives better engine and hydraulic component life.

Albert Toal, General Manager Lincom Group, says the MBP range uses the best components and latest manufacturing techniques. Albert says the design and build means the PRONAR range of mobile trommel screens are perfectly suited to work in various materials such as soil, compost, municipal waste, coal, aggregate and biomass. The trommel can be set up according to industry requirements, with the addition of any of the optional equipment such as electric drive in lieu of diesel engine, air separators, magnetic head drums and extra hydraulic pumps.

The new 562 gross horsepower (419 kW) Cat® 836K landfill compactor delivers on more than 20 years of durable reliability and ease of service by ensuring the operator’s health, productivity and safety are all standard features.

The 836K advances the solid engineering of its predecessors with new wheel and tip configurations and enhanced safety and serviceability. The 836K comes equipped with one of three new wheel and tip con gurations available to meet the operator’s desired application.

A standard rear-view camera enhances overall visibility for the operator while a new instrument pod features membrane switch panels and automatic temperature control – improving operator comfort. Interior and bystander sound levels are reduced, with optional sound-suppression packages available. To protect key components and systems from damage, the 836K uses specialised guarding, including hydraulically actuated engine and power-train shields and front-frame guards to prevent trash build-up inside the frame. Axle-seal guarding stops material from binding around the axles.

The 836K’s Auto-Blade feature automatically raises the blade when the machine reverses and lowers the blade to a pre-set height when it moves forward. The STICTM steering controller uses a single lever for steering and transmission control, allowing the operator to sit comfortably back in the seat, reducing fatigue.

For optimum efficiency, the 836K can be fitted with the Cat Compaction Technology. Using a Global Navigation Satellite System and digital terrain files, the system delivers real-time information via an in-cab display to assist the operator in determining the appropriate number of passes for the level of compaction required.
