SWARF BURN OFF
Rotajet provides specialist burn off solutions for oily metal sludge, grinding fines, metallic dusts, filter cake, machining sludge, and ultra-fine metallic waste generated across a wide range of industrial manufacturing, machining, and metal recycling operations.
Using advanced Pyrolysis Burn-Off Technology, oils, coolants, emulsions, water, greases, and organic contamination can be removed from difficult-to-process metallic waste streams, leaving behind a dry, clean, oil-free metallic material suitable for recycling, briquetting, remelting, or metal recovery.
Specialist Sludge & Fines Processing
Rotajet has extensive experience processing difficult metallic waste streams generated throughout industrial manufacturing and metal recycling industries. These waste streams often contain extremely fine metallic particles mixed with:
- Oils
- Coolants
- Water
- Lubricants
- Greases
- Metallic contamination
- Process residues
Why Rotajet Pyrolysis Processing is More Effective Than Traditional Washing
Rotajet offers a specialist Pyrolysis Burn-Off Service specifically developed for difficult metallic waste streams that cannot be efficiently processed using conventional washing systems. During the thermal treatment process oils and coolant are vapourised, whilst any organic contamination is thermally decomposed. The emissions produced by this process are only CO2 and water vapour, and the remaining metallic material is left dry, clean and oil free.

Grinding Sludge Recycling Solutions
Grinding sludge is one of the most difficult metallic waste streams to process due to the extremely fine particle size and high levels of coolant contamination. By removing oils, coolants, and moisture contamination, Rotajet can significantly improve recycling potential and reduce disposal costs associated with grinding sludge waste.

FAQ
Metal sludge is a waste material containing ultra-fine metallic particles mixed with oils, coolants, water, and machining contamination generated during industrial manufacturing processes.
Grinding sludge is a mixture of fine metallic particles, coolant, oils, and abrasive residues generated during grinding operations.
Fine metallic particles rapidly block filters and screens, making conventional washing and filtration systems inefficient for sludge-like materials.
Rotajet pyrolysis processing uses controlled thermal treatment rather than mechanical filtration, allowing oils, coolants, and moisture to be removed without screen blinding or filter blockage.
Yes. Following Rotajet pyrolysis treatment, the material becomes dry and oil-free, making it suitable for recycling, briquetting, or remelting.
Yes. Rotajet pyrolysis systems are highly effective for processing wet machining sludge contaminated with oils and coolants.
Yes. Oils, coolants, emulsions, and moisture are removed during the pyrolysis process.
Vapourised hydrocarbons are processed through an afterburner system where emissions are reduced to CO₂ and water vapour.
Yes. Following pyrolysis treatment, the remaining metallic material is dry, clean, and oil-free.
Yes. Dry metallic fines are significantly easier to briquette and prepare for recycling or remelting.
Common industries include aerospace manufacturing, automotive production, CNC machining, grinding operations, precision engineering, and metal recycling.
Yes. Rotajet can carry out free trial processing to evaluate sludge and fines materials before full-scale production processing.
Rotajet typically requires a representative 25 kilo sample for free trial processing and evaluation.
Yes. Removing oils and moisture from sludge can significantly reduce hazardous waste disposal volumes and improve recycling value.
No. The process is specifically designed to remove contamination while leaving the metallic material suitable for recovery and recycling.
