Environmental Clean Technologies Limited (ASX: ECT) (“ECT” or “Company”) is pleased to provide the following update on the progress of its Coldry Upgrade Project (“Project”), located at Bacchus Marsh, Victoria.
- Phase 1 of the Coldry Upgrade Project scheduled for completion Q1, FY22
- Phase 2 scheduled for completion in 2H, FY22
- Overview of Project activity completed over April to June 2021
Status Update – Coldry Small-Scale Commercial Demonstration
In its 23 March 2021 ASX announcement, the Company provided an update on the progress of its Project, aimed at delivering the small-scale commercial demonstration of its unique, low-cost, zero-emission Coldry lignite drying technology in Victoria, Australia.
The successful completion of this small-scale commercial demonstration plant is part of the Company’s broader commercialisation strategy, which involves the further potential scale-up of our Coldry process in Victoria’s Latrobe Valley, supporting the higher value, lower emission utilisation of lignite via a range of downstream applications, including solid fuel, liquid fuel, specialty chemicals and hydrogen production.
As previously reported, the Project has been impacted by COVID19, initially through lockdown last year and more recently through delays across the international supply chain for various components, driven by persistent COVID19-related manufacturing and shipping delays across Asia.
Offsetting some of these impacts was the recently announced acquisition of a locally-sourced char kiln, the key component of Phase 2 of the Project. The ability to source this component locally has resulted in an approximate $500k saving and a four-month reduction in the time to complete Phase 2 of the Project.
ECT’s Executive Chairman, Glenn Fozard comments:
“The ongoing supply chain uncertainty resulting from COVID-19 has led to an adjustment to the timeline reported in March to complete Phase 1 of the Project. However, with the delivery of the rotary kiln in the coming weeks, we anticipate recent Phase 1 delays will be offset during Phase 2, bringing the completed Project online during the second half of FY22.”
In relation to Phase 1 of the Project, the scale-up of the Coldry process, Chief Engineer Mr Ashley Moore added:
“We have now received our final shipment of plant and equipment from international suppliers.
“Despite the delay of this final shipment of plant and equipment for Phase 1, we have successfully installed some of the most difficult elements of our primary processing train, namely the hammer mill and raw coal hopper (see photo, right).
“In addition, we have completed the majority of the local fabrication works, with installation for local and imported equipment continuing.”

Coldry Upgrade Project Activity: April – June 2021
Installation of hammer mill & coal hopper
Current Status: 90%Complete
Following the completion of the support structure activity, the surge hopper and hammer mill were recently lifted into position and assembled during a 15-hour operation.
The coal hopper consists of 3 sections; platform (below, left), upper hopper section (below, centre) and lower hopper section (below, right), weighing a collective 18 tonnes. Sitting on top of this is a 4-tonne hammer mill (shown further down).
Due to the size and weight of the components, the height of the building and the relatively confined installation area, the team opted for a ground-up approach to installation, assembling the platform and upper hopper, then using a 20-tonne Franna crane to position it for handoff to the 100-tonne slewing crane. The 100t crane then raised the upper section, allowing the lower hopper section to be brought in for sealing and assembly.
Following the attachment of the legs to the hopper, the assembly was lifted into place above the previously installed mixer, mill and extruder, in an operation that required precision manoeuvring with less than 5cm clearance at specific points.
The final element was the placement of the hammer mill via the roof.
The next steps to finish installation include the addition of access platforms and guard rails, and electrical cabling.
Installation of mixer, mill & extruder
Current Status: 95% Complete
Following the installation of the mixer, mill and extruder, cabling work has progressed, along with installing the raw coal hopper and hammer mill activity outlined above.
The next steps required to complete the installation of the mixer, mill and extruder include the addition of access platforms, guard rails and electrical connection.
Packed bed dryer upgrade
Current status: 65% complete
- Removal of internal walls and preparation for new installations (complete)
- Installation of the revised wall, inlet & floor design, aimed at further improving drying efficiency
The upgrade of the packed bed dryer involves the replacement of the internal walls with an improved design, building upon learnings from the previous pilot plant.
Aimed at further improved drying efficiency, the updated design is expected to deliver increased throughput and decreased cost of production, supporting the higher capacity of the new primary processing train.
The next steps to complete the Packed Bed Dryer and system construction include the lift of the above pictured internal walls into the existing structure, securing in place, installing monitoring equipment, and installing access platforms.
Structure and platforms – installation
Current status: fabrication complete; installation 40% complete
With fabrication completed, preparation of the support structures, involving sandblasting, priming and painting, proceeded in line with the Project timetable.
Build of raw coal storage, workshop and laboratory
Current status: 90% complete, awaiting fit-out of lab
- Relocation of existing work shelter and construction of new, double-stacked enclosed raw coal storage
- Customised 40ft containers to act as a new undercover workshop and clean laboratory
- Electrical installation of lighting, power points complete (photo, below right)
- Power supply installed
Preparation of the process building ahead of the installation of new equipment
Current status: 95% complete
Still to be completed:
- Sub-floor bracing for new loads
- Roof reinstatement (pending installation of packed bed dryer upgrades)
- Building cladding reinstatement (pending completion of construction activities)
Heat system upgrades
Current status: In progress, not critical path
Significant upgrades have been planned for the existing hot water system to optimise operation—upgrades target reliability, capacity and control system integration.
Holding tanks, fuel centrifuge, and other equipment (pictured, right) have been completed and await plumbing and electricals to complete installation.
The heating system simulates ‘waste’ heat for demonstration purposes initially, facilitating the commissioning of the Coldry process train, which will then transition to a backup role following the installation of the syngas-fired boiler system included as part of the Phase 2 char process train.
New electrical & process control room (system automation & diagnostics)
Current status: 60% complete
Overview: Designs and specifications complete, including main circuit breakers, power management and individual drive control systems. The motor control centre (MCC) is being fabricated, and the building which will house the equipment is also in the process of fabrication and installation. Once the MCC panels are ready, installation is then “bolt-in”, followed by a period of cabling and termination works.
Conditioning system fabrication, installation and testing
Current status: 60% complete
Overview: Design, sourcing and selection of the belting system – a vital component of the conditioning system. Following shipping delays, all components are now on-site, and the local fabrication of the conditioning unit is complete, with assembly due to commence shortly.
The remaining components of the conditioning system have been fabricated since the last update, ready for assembly.
