Our Business
Founded in 2005 by industry veteran Carey O’Keefe, Lime Systems Bulk Storage Solutions has grown from Perth, Australia, into a globally recognised leader in bulk material handling. With nearly five decades of expertise, Carey laid the foundation for a company operating across Asia, Africa, South America, and Europe.
We specialise in mining and processing operations, particularly in bulk handling, conveying, mixing, metering, and dosing of materials such as lime, reagents, new minerals, and rare earths.
Driven by a can-do culture and innovative engineering, we deliver purpose-built, high-performance equipment with exceptional customer service. Our core values — integrity, reliability, and collaboration — underpin lasting partnerships with clients and suppliers.
As a performance-driven team we have a broad range of operational knowledge covering all aspects of mining and processing operations.
Our Project Approach
Using a Stage-Gate project management methodology, we fully immerse ourselves in our clients’ needs. This structured process ensures smooth project execution from concept development to final design approval, culminating in delivering precision-engineered mechanical equipment.

How We Work
With a structured project management methodology, that leaves nothing to chance, our team meticulously plans, optimises, and executes every stage with clarity and precision.
We thrive on solving challenges, keeping things moving, and delivering results that work first time, every time.
Our precision sets us apart.
Through tailored solutions, modular design, and a structured gate process, we minimise risk, reduce downtime, and maximise value.
At Lime Systems, we don’t just deliver products—we engineer and deliver fit-for-purpose solutions. Each solution is tailored to our clients’ unique needs, never off-the-shelf. Our commitment to quality ensures that every product arrives on-site ready to perform, enabling seamless integration and immediate value from day one.
Our modular plants are engineered, and built to integrate effortlessly into your project site.
By minimising on-site construction, we help reduce costs, lower risk, and accelerate timelines—delivering outcomes faster and more efficiently.
Every module is pre-tested and built to rigorous standards, ensuring reliable, day-one operation and a smoother path to commissioning.
Our structured gate process ensures transparency and trust from the start.
At every gate, key stakeholders review progress, make informed decisions, and align on the path forward. This collaborative approach ensures a deep understanding of the project’s challenges and goals, transforming them into practical, value-driven engineering solutions.
