As the construction and recycling sectors face growing pressure to improve environmental performance, Circular Group is highlighting the critical role of logwashers particularly its Titan® Logwasher in advancing sustainable aggregate processing across the UK and Ireland.
With tightening environmental requirements under WRAP, SEPA, and ISO 14001, operators are expected to recover more usable material, minimise waste, and reduce water consumption. Yet, many of the challenges to sustainability begin with the feed itself. Clay-bound stone, contaminated soils, and construction waste remain among the hardest materials to clean efficiently using traditional washing systems.
Circular’s Titan® Logwasher is engineered to tackle these issues head-on — delivering cleaner outputs, lower water consumption, and measurable reductions in waste-to-landfill.
Reducing Water Consumption Through Integrated Systems
Traditional wash plants can consume large volumes of fresh water, particularly when treating heavily contaminated feed. When integrated into a closed-loop water recycling system, however, logwashers can operate with minimal freshwater input.
Circular typically configures the Titan® Logwasher alongside its SiltPro® High-Rate Thickener, Filter Press, and Dewatering Screens, forming a fully optimised washing and recovery circuit. This combination allows operators to achieve:
Up to 90% process water recovery
Lower energy usage due to efficient solids handling
Compliance with SEPA and Environment Agency discharge limits
This integrated approach reduces both environmental footprint and operational costs, helping sites align sustainability targets with commercial performance.
Supporting Circular Economy Principles
At the heart of the circular economy is the transformation of waste into resource. The Titan® Logwasher enables precisely that.
By cleaning and liberating aggregates from clay, organics, and contaminants, previously low-value or rejected materials can be repurposed as saleable construction aggregates. This reduces the industry’s reliance on virgin quarried material while maintaining strict quality and grading standards.
Circular’s engineering team designs each system around the feed characteristics of the customer, ensuring efficient separation, optimal recovery, and seamless integration with downstream technologies such as SandPro® and XScalp® units.
Lower Energy and Maintenance Requirements
Sustainability also means efficiency. The Titan® Logwasher incorporates:
High-efficiency drives and gearboxes to reduce power draw
Low-maintenance bearings and liners to extend service life
Accessible inspection points for quicker checks and less downtime
By optimising energy use and reducing component wear, the system helps operators achieve lower lifecycle emissions and improved plant uptime.
Clean Output, Compliant Operation
Regulatory compliance remains a top priority for operators under Environment Agency and SEPA frameworks. Poorly washed material or excess silt discharge can lead to environmental breaches and financial penalties.
The Titan® Logwasher produces consistently clean, specification-ready aggregates that meet BS EN standards for concrete, asphalt, and drainage applications. Cleaner output supports:
Reduced silt carryover
Reliable grading compliance
Higher acceptance rates from end users and contractors
In short, operators achieve better product quality while maintaining environmental responsibility.
Built for Local Conditions
Every installation is engineered to meet regional compliance and site-specific sustainability goals. Circular’s bespoke design process considers feed material, water availability, and local environmental limits.
Custom adjustments to shaft speed, paddle configuration, and water injection ensure optimal performance whether operating under SEPA discharge consents in Scotland or WRAP certification schemes in England.
Proven Results
Circular’s installed logwasher systems have demonstrated measurable gains in both environmental and operational metrics, including:
30–40% increase in aggregate recovery from contaminated feed
Up to 70% reduction in waste-to-landfill volumes
90% water recycling efficiency with SiltPro® and Filter Press integration
Lower CO₂ output due to reduced transport and disposal requirements
These results show that sustainable washing technology is not only achievable but commercially advantageous.
The Sustainable Core of Modern Wash Plants
The Titan® Logwasher is more than a heavy-duty cleaning solution — it is a cornerstone of sustainable aggregate and recycling operations. By maximising recovery, reducing water use, and producing compliant, saleable material, it allows operators to meet modern environmental standards without compromising performance.
With its Northern Ireland engineering heritage and commitment to precision manufacturing, Circular Group continues to deliver wash plant solutions that combine sustainability, reliability, and long-term return on investment.
