A frequent question shops ask is whether they should spin their chips to send to a recycler, or if they should briquette. They ask questions like: How can we consolidate our chips to get the highest resale value? Would we maximize the value of our scrap by briquetting? Or is spinning the chips the best option? Assessing the Situation […]
Most of the hazardous waste in surface finishing comes from wastewater that is generated by rinse water. Due to the substantial amount of this waste, within this $155 billion dollar industry, companies are taking quick action to mitigate the environmental risk associated with dumping, and consumption. One of the major steps is though pollution prevention planning and water conservation. […]
Metalworking fluid is a blend of many chemicals that’s main job is to help oil emulsify into water. Many years ago, this fluid contained carcinogens, until 1970 when it was outlawed from both sale and dumping down the drain. Without the carcinogens, metalworking fluid is not resistant to bacteria growth and in the right conditions, in a short amount […]
Electronic waste, or e-scrap is the fastest growing segment of the world’s solid waste stream, predicted to continue to have significant growth in the next five years and beyond. It is also one of the most difficult to dispose of and recover. Recycling methods used for electronic scrap vary, because the components often contain hazardous materials that may include: […]
If you need a more effective and profitable way to reclaim your metalworking fluid, a modern coolant recycling equipment is the proven answer. Implementing the right fluid reclamation system provides fast ROI and enhances profits, equipment lifespan and employee safety. Costs of Not Filtering Machine Tool Coolant While water comprises most of the coolant, it’s the concentrate in it that […]
Electroplating, electroless nickel plating, metal-forming operations, battery recycling and other such operations all generate wastewater containing soluble heavy metal ions. Ultrafiltration and precipitation are the most effective methods for removing these metal ions. Both help manufacturers avoid the costly consequences of non-treatment, that can include corrosion to systems, toxic pollutants passed into surface waters, sludge disposal, and more. Finding […]
According to the Aerospace Industries Association, few if any industries have done a better job of improving environmental performance over the last several decades than the aerospace industry. The AIA states that today’s aircraft and engines are considerably more efficient than those manufactured just 20 or 30 years ago, which has dramatically decreased fuel usage and harmful emissions. Additionally, […]
Evaporation, or distillation, is a separation process that takes advantage of the changing physical states of water, or other solvents, from liquid to vapor. It is unique from other separation processes, in that the water is removed from the contaminants rather than the pollutants being filtered from the water. Before recent technological developments, the capital and energy requirements for […]
A worldwide manufacturer of complex metal components for the aerospace industry needed to achieve maximum recovery of its cutting fluids from scrap material that was being machined at its facility in the Pacific Northwest. Additionally, the company wanted to receive a higher value for its scrap by removing the maximum amount of coolant possible from the material, as well […]
Mechanical and surface treatment processes in the automotive, aviation, and appliances industries require large quantities of water and produce highly pollutant wastewater that cannot be discharged directly into the sewer without proper treatment. This requirement can easily increase a company’s operating costs. A feasibility study in each case for treatment of these wastes is recommended. This study was used for […]
