Introduction: When Surplus Becomes a Burden
In industrial operations, especially those involving deep mining or large-scale hydraulic systems, lubricant management can become unexpectedly complex. One striking example involves a UK phosphate mine generating nearly 20,000 liters of unused Fuchs Aquacent LT100 hydraulic fluid monthly. Despite being unused—merely flushed from lines during scheduled maintenance—the fluid accumulates rapidly, creating logistical and financial challenges. This article explores disposal options, repurposing strategies, and market considerations for surplus hydraulic lubricants, with a focus on nonflammable, water-based formulations.
Understanding the Product: Fuchs Aquacent LT100
Fuchs Aquacent LT100 is a specialized hydraulic lubricant designed for fire-resistant applications. It is:
Terminology Note: ISO VG and Fire-Resistant Fluids
- ISO VG (Viscosity Grade): A classification system for lubricant thickness. VG 100 indicates a relatively thick fluid suitable for heavy-duty hydraulic systems.
- Fire-Resistant Hydraulic Fluid: A lubricant formulated to reduce flammability risk, often used in mining, steel mills, and foundries.
Challenges in Disposal and Resale
The primary obstacles to repurposing or selling surplus Aquacent LT100 include:
While direct resale may be difficult, creative repurposing can unlock value:
In one case, engineers explored blending water-based hydraulic fluid with diesel for use in industrial kilns. The high viscosity of VG 100 required dilution to below 2.5% concentration to avoid altering fuel properties. While technically feasible, the cost of water removal and blending equipment outweighed the benefits. Still, the experiment highlighted the potential for niche applications when approached creatively.
Recommendations for Disposal and Market Outreach
The mine’s contract required scheduled flushing and continuous supply, regardless of actual usage. Even though only 20% of the fluid was wasted, the inability to reuse or return unused lubricant created a recurring surplus. This situation underscores the importance of flexible procurement contracts and efficiency audits in fluid management.
Conclusion: Turning Waste into Opportunity
Surplus hydraulic lubricant, especially specialized formulations like Fuchs Aquacent LT100, presents a unique challenge—but also an opportunity. With strategic outreach, creative repurposing, and a clear understanding of product limitations, operators can reduce waste, recover value, and contribute to more sustainable industrial practices. In a world where every liter counts, even nonflammable fluid can ignite innovation.

Understanding the Product: Fuchs Aquacent LT100
Fuchs Aquacent LT100 is a specialized hydraulic lubricant designed for fire-resistant applications. It is:
- Water-based, with approximately 41% water content
- ISO VG 100 viscosity grade
- Nonflammable, making it ideal for underground mining
- Priced at approximately £34 per liter when new

- Fire-Resistant Hydraulic Fluid: A lubricant formulated to reduce flammability risk, often used in mining, steel mills, and foundries.
Challenges in Disposal and Resale
The primary obstacles to repurposing or selling surplus Aquacent LT100 include:
- High water content, which limits combustion potential
- Specialized formulation not compatible with standard hydraulic systems
- Geographic limitations—shipping from the UK increases cost
- Limited demand outside niche industries like deep mining or tunnel boring
- Water content: ~41%
- Viscosity: ISO VG 100
- Storage: 1,000-liter IBC totes
- Shelf life: Typically 12–24 months if sealed
- Disposal cost (used fluid): ~$0.10 per liter
- Market value (unused): Potentially £10–£20 per liter if repurposed
While direct resale may be difficult, creative repurposing can unlock value:
- Offer to underground mining operations with similar hydraulic systems
- Explore use in hydraulic systems for tunnel boring machines
- Investigate compatibility with industrial kilns or furnaces (low concentration blending)
- Partner with universities or research labs for fluid dynamics testing
- Use in fire-resistant hydraulic training simulators or mock systems

Recommendations for Disposal and Market Outreach
- Contact regional waste oil processors to explore bulk disposal contracts
- List surplus fluid on international industrial marketplaces with clear specifications
- Offer samples to potential buyers for compatibility testing
- Negotiate with original suppliers for partial buyback or credit
- Collaborate with OEMs to identify compatible equipment or retrofit opportunities
- Convert surplus into training stock for hydraulic maintenance programs
- Use fluid in non-operational systems for leak testing or flushing
- Partner with fire safety organizations for demonstration purposes
- Explore government or military applications where fire resistance is critical
