The metalworking and metal forming industries have taken a leadership role in protecting the environment through an emphasis on fluid recycling and metal recovery. Shop managers understand fluid recycling can be an integral part of their process, just like tooling, inspection and everything else that affects their bottom line. In addition, other managers have developed systems that produce a revenue stream by recycling copper chips.
Save 60% in coolant cost
Coolants have improved significantly over the past and are better than those from 10 or 15 years ago. They last longer, but the cost has also increased. Depending where a business is located in the Unites States, shop managers pay up to $40 per gallon for coolant. Disposal costs can vary, anywhere from 25 cents to $3 per gallon.
A coolant mixture is usually 90 percent coolant with 10 percent water. Companies often end up paying to haul the used coolant away, and then refilling machines with brand new coolant. This adds to the cost of maintaining the equipment.
There is a cradle-to-grave responsibility for a metalworking shop, even if a certified company is hired to dispose of used coolant. If the coolant is not properly disposed, federal and state authorities can come back to the generator of the waste to pay for clean-up costs. This leads to more expense and potential embarrassment.
This is where fluid recycling is valuable. Companies can save up to 60 percent of the coolant concentrate by removing tramp oils and solids through filtration. That is a sizable payback, but there are other factors that contribute to potential return on investment (ROI).
Enhance machine tool performance
Removing tramp oil from the manufacturing process is critical as their removal improves fluid performance and longevity, air quality, bacterial resistance, corrosion resistance and tool life. Removing small fines will lead to better tool life, better parts finish and reduced machine tool wear.
Improve air quality
Removing tramp oil from coolant on a regular basis results in less oil mist in the air, which improves air quality. Keeping the working area cleaner also reduces the amount of slippery moisture on floors and contributes to a healthier atmosphere for shop workers. Fluid recycling can save money, limit liability and increase the health and safety of the individuals in the shop. These are all important benefits to shop managers who pay close attention to dollars. A fluid recycling program also helps companies achieve and maintain ISO 14000 status.
