Go green and reduce waste with RUF sludge briquetting machines

Most people think sludge is so hard to handle, dumping it is the only option. But RUF briquetting has a better solution. 

Automotive manufacturers, aerospace, parts manufacturers, and machine shops waste 50% to 60% of oil and fluids as part of normal operations. Most manufacturers pay high prices to dispose of sludge in a landfill. Handling and transporting thick, heavy, and often hazardous materials requires a lot of labor to ensure proper disposal. Briquetting sludge (or swarf) solves these problems.

Briquetting is a cleaner, safer, cost-efficient way to dispose of waste, while recovering some of the value trapped inside the sludge.  

  • Briquette your grinding sludge and reuse the salvaged cutting fluids, grinding oils, or emulsion for your own operations 
  • Savings add up quickly: If you reclaim just 50 gallons of oil worth $15 per gallon, that’s $750 
  • Resell briquettes wherever you sell other chips 
  • Reduce energy, labor and transportation costs associated with disposing of sludge
  • Meet company sustainability goals 
  • Keep hazardous materials out of landfills 
  • No artificial binders are used that can lead to combustion or burn off while melting

RUF briquetters produce a denser, more consistent briquette than other briquetting machines. And, RUF machines are the only proven solution for reclaiming sludge. What makes our machines so different? Take a look under the hood.

RUF is the only briquetting manufacturer to offer a proven solution for sludge.

Centrifuges and filters have been tested and proven ineffective at removing adequate fluids from metal. RUF briquetting systems are the only ones available that can recover up to 97% of cutting fluids. With more than 5,500 briquetters in operation, RUF can help you squeeze out excess oils and fluids and reclaim them for recycling or reuse.

  • Excellent ROI: RUF briquetters often pay for themselves within 18 months
  • Over 5,500 briquetters in operation worldwide 
  • We offer a free briquette test of your material to prove out a solution and demonstrate ROI up front 
  • RUF briquetting machines are compact and integrate easily into existing production lines
  • Our briquetters require little to no supervision and can run 24/7, keeping labor costs low

RUF swarf briquetting systems work with a variety of metals.

How are sludge briquettes made?  

Step 1

Grinding sludge is transferred from the machine into the briquetter.

Step 2

The sludge is compressed—squeezing out excess oils and fluids—while transforming the metal chips into metal briquettes.

Step 3

The oil pressed out during the briquetting process is pumped directly from the briquetter into tanks. The oil passes through a filter so it can be easily recycled and reused.

Step 4

The metal briquettes that are extracted from the sludge can be transported and recycled.
