View your landfill in 3D

No longer limited to intensive gaming or high-end architecture, virtual reality is making in-roads in the landfill sector.

Landair Surveys, a leading surveying firm in Australia, has introduced a new way for their landfill clients to interactively view their site data.

Previously, waste managers relied on 2D plans and concept drawings to visualise the relationship between existing site conditions and future operations. However, the rise of 3D viewing platforms has led to the possibility of creating virtual landfills where many different spatial data sets can be viewed simultaneously.

The surveyors at Landair now offer prospective clients virtual landfill models that can be tailored to individual landfill sites or operational requirements. The models can be as simple as an online visual tool to a downloadable interactive viewer allowing the user to take basic measurements and create clipping planes.

  • Examples of current virtual files created for landfill operators include:
  • Design top of waste contours overlaid on existing landfill surfaces
  • Design clay sideliner files overlaid on existing rockface surveys
  • View of proposed finished top of cap levels from site boundaries
  • Month by month landfill cell flyover comparisons
  • Composite as built clay liner and subgrade checks.

Carrying the load

Liebherr’s powerful materials handlers and wheel loader models have helped recover construction and demolition waste.   Read more


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.

Selecting the right portable generator

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

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.

Compost Revolution

Food waste accounts for nearly half of average household waste and keeping this out of landfill can significantly reduce costs.

It is for these reasons that Compost Revolution has spent the past five years engaging more than 18,000 households across Australia to help scale organics recovery for councils. During this time, they say they’ve also managed to divert more than 4000 tonnes of food waste from landfill while saving councils more than $1 million in landfill costs. Designed with councils for councils, the Compost Revolution is an all-in-one education, infrastructure logistics and marketing program to scale home composting and worm farming in local government areas across Australia, helping councils achieve their waste and emissions targets while cutting costs.

Compost Revolution works with local government to tailor-make a program suited to their area. The organisation provides councils with real-time quantitative data, resident behavioural information and integrated social media platforms, allowing them to increase public education around composting. Real-time quantitative data uses industry-tested methodology to calculate the total kilograms of waste from landfills, carbon dioxide-equivalent greenhouse gas emissions avoided, waste collection cost savings and the total number of households engaged.

The organisation’s online educational platform and home deliver service allows councils to run their own Compost Revolution. Residents can complete a quick online tutorial and quiz to learn about composting, worm farming or bokashi bins, then order and pay for their kit through an integrated e-commerce platform.
