BeneTerra Expands Landfill Services

There is a lot more to BeneTerra than many realise. In another first,  BeneTerra recently reinstalled a geotextile separation layer for a regional Queensland council landfill.  The council had previously installed the layer only to have it destroyed by one of Queensland’s famous summer storms.  We were able to arrange for the QC/QA checks on the existing replacement rolls which were a few years old and ensure there was sufficient material that met the required engineering specifications to complete the installation.  Given the expected timeline between completion of the installation and the first waste being laid in the new cell, we were able to utilise stockpiled car tyres as ballast.  The job was delivered ahead of time, on budget with no variations and importantly within the engineering specification and QA/QC requirements.

BeneTerra has a wide range of skills and expertise that covers almost any job that impacts on environmental compliance.  Separation layers and liner repairs in landfills, regulated dam structures inspections and repairs, erosion prevention and repairs, capping rehabilitation and civil works, irrigation systems, environmental monitoring are just a few of the services we provide to the landfill industry.



First BeneVap Goes to New Zealand

We recently delivered a refurbished BV300 to a landfill near Auckland, New Zealand. The machine known as Christine was originally built in the USA and used on some oil and gas projects there. It was first shipped to Brisbane where BeneTerra staff performed  

upgrades to meet Australia / New Zealand gas and electrical standards. The control program was also upgraded and metricised. 

BV300 headed to New Zealand

Unfortunately, due to the COVID-19 pandemic, our crew was unable to travel to New Zealand. Commissioning has been a challenge without actually being on site.  Through videos and extensive communications with their counterparts in New Zealand they succeeded. The SCADA system and a cellular  modem allow them to communicate with the control panel and track performance along with the operators on site.

Depicted here (left to right) are staff members Steve Hillsdon, Alastair Berking, Billy Dean

and Tim Woods. Both Steve, whose wife is from New Zealand, and Alastair, a New Zealand citizen, have deep connections there and are anxious to be hands on but travel restrictions have challenged their ability to provide service remotely. 


Harini Pani Presents Landfill Leachate Characteristics and Treatment at WMRR

BeneTerra chemical engineer, Harini Pani, gave a presentation entitled “Landfill leachate characteristics, management and treatment alternatives” on 28 March at the 2019 Waste Management and Resource Recovery conference held in Brisbane, Australia. Harini discussed the biological decomposition processes that affect landfill leachate quality and various treatment alternatives. She further explained how the BeneVap submerged combustion, evapo-concentration process produces a more benign residual that can be returned to the landfill while removing more than 90% of the water volume.

The 2019 Waste Management & Resource Recovery Association of Australia (WMRR) national innovation and excellence award for landfill operations was given to BeneTerra and Remondis for the Swanbank landfill leachate reduction project. By working closely with BeneTerra to integrate a BeneVap evaporator into their leachate gathering and disposal system, Remondis has been able to tightly manage and control leachate levels within the landfill. Previously, Remondis had recirculated the leachate upon the landfill cap in an effort to evapoconcentrate and that was only marginally effective. The new BeneVap system evaporates 30,000 litres per day from the system  leaving behind 5% residual that is deposited back in the landfill. hashtagwastemanagement hashtagWMRR hashtaginnovation hashtaglandfills hashtagleachate


BeneTerra welcomes two new soil scientists

During Jason Choong’s second year of university he became interested in a soil science course that consisted of practical components and field work where he could be hands on working with soil profiles. He flourished under the mentorship of his honours professor. Now a graduate soil scientist, Jason feels that environmental stewardship is meaningful and important but often overlooked. He signed on because his honours project mirrored what BeneTerra puts into practice. He attained a Bachelor of Agricultural Science, with Honours, from the University of Queensland. His thesis focused on the Effect of basalt soil amendment on soil properties and plant growth. When he’s not researching or working, he enjoys a game of social badminton.

Along with his background working in environmental management, Calvin Leech has submitted his PhD in Soil Science with a Thesis that focuses on bio remediation of polycyclic aromatic hydrocarbon (PAH) contaminated soils using a composting process. The PAH compounds are generated during incomplete combustion materials such as coal and some of these PAHS are U.S EPA priority listed pollutants due to being known or potential cancer-causing compounds. During the study he determined the major limitations for the composting remediation strategy and implications for remediation of PAH contaminated MGP soils. Calvin has a Bachelor of Resource Management from the University of New England and is a PhD candidate in soil pollution research. He joined BeneTerra because of the unique opportunity to conduct applied soil science across a range of industries. In his free time, he likes to compose music, ride his mountain bike and play hockey.

BeneTerra Addresses Landfill Leachate Reduction at WasteQ Conference

Chief Technical Officer, John Zupancic and chemical engineer, Harini Pani, presented a paper entitled, “Landfill leachate volume reduction and chemical transformation with BeneVap submerged combustion treatment” at the Waste Management Association of Australia Queensland (WMAA) Conference last October. Both presented findings of chemical analyses of leachate before and after evapoconcentration within the BeneVap system.

The BeneVap submerged combustion technology not only reduces leachate volume by more than ninety percent but several significant chemical changes were noted between the leachate and concentrate. For example; over ninety eight percent of the ammonia in the leachate was lost from the solution and numerous metals were made insoluble as they combined with carbonates, phosphate and silicate.

John Zupancic

When asked about the potential for source term depletion of leachate constituents over the life of a landfill cell, Zupancic said, “We believe that in the future, we will be able to customise previous and post treatment to optimise ammonia loss and sequester metals in the BeneVap concentrate.”

Pani specialises in predicting chemical transformation of varying leachate qualities to anticipate the effects of heating and concentration during the BeneVap treatment.  She performs lab bench simulations and runs computational models to estimate the effects of evapoconcentration. Currently, she’s gathering more empirical data to refine the predictive models.

John Zupancic is also Managing Director of BeneTerra with offices in Brisbane and Sheridan, WY, USA. His background in soil and water chemistry has aided in solving wastewater and land related problems for over 30 years.  He holds a BSc degree from Colorado State University and an MSc from the University of Nebraska.


BeneTerra Welcomes New Intern

Alastair Berking, our newest intern and avid rugby player, specifically chose BenTerra because it’s environmental services offered are unique and incorporate numerous ideas and concepts that are possible groundbreaking technologies in the near future. “I believe BeneTerra is the perfect place to be for that reason,” Berking said.

The fourth year Griffith University student is in his final stages of completing a Bachelor of Environmental Engineering. For the last two years, his primary focus has been wastewater and stormwater treatment systems.

The soon to be graduate has hit the ground running at our Toowoomba site. During his internship he’ll be assisting engineers on the active Benevap projects with tasks including; the conducting of experiments  and tests, collecting of data and compiling of operational/safety procedure  documents. It’s also the people at BeneTerra Alastair is enjoying “I like the practical application and collaboration of working with other engineers,” he said.

BV300 evaporating mixed leachate and stormwater

BeneTerra completed the evapoconcentration of landfill leachate that had made its way into a stormwater pond following weather events that followed Cyclone Debbie. The BV300 reduced 470,000 litres to 3,500 litres over a few days and nights during which time clean steam was released to atmosphere. The constituents in the leachate were concentrated and placed back into the landfill.
