Reduce coolant consumption and disposal volume.

Coolant recycling keeps usable fluid in service, reduces new-fluid demand, and can reduce the amount of spent coolant sent for disposal. Each facility remains responsible for its waste determinations, exposure controls, records, and regulatory requirements.

Operational impact

Measurable fluid and waste reduction

Measure the change through fluid purchases, disposal volumes, and coolant condition.

Compare equivalent operating periods before and after implementation. Coolant filtration supports the facility's fluid-management program while environmental, health, safety, testing, and recordkeeping responsibilities remain with the facility.

Regulatory framework

Requirements depend on the fluid and facility

Spent coolant is not automatically hazardous waste. The facility must evaluate its own waste, exposures, processes, jurisdiction, and applicable requirements.

01Worker exposureOSHA · 29 CFR 1910.1000 Table Z-1 · NIOSH Pub 98-102OSHA's air-contaminant table lists 5 mg/m³ for mineral-oil mist. NIOSH recommends 0.4 mg/m³ thoracic particulate mass, or 0.5 mg/m³ total particulate mass as a sampling alternative, for metalworking-fluid aerosol. The applicable evaluation and controls depend on the fluid and process.
02Hazardous-waste determinationEPA RCRA · 40 CFR 262.11The generator must determine whether each waste is hazardous. The determination is made at the point of generation using applicable listings, characteristics, test results, and process knowledge, and it must be revisited if the waste may have changed.
03Discharge to sewerClean Water Act · 40 CFR Part 403 & 433Federal pretreatment prohibitions, any applicable categorical standards, and local sewer requirements govern industrial discharges. Confirm the applicable requirements and obtain the required authorization before discharging spent coolant.
04Management systemsISO 14001 & ISO 45001ISO 14001 addresses environmental-management systems, while ISO 45001 addresses occupational health and safety. Each organization determines its environmental aspects, workplace hazards, objectives, controls, and supporting records.
05California overlaySCAQMD Rule 1144South Coast AQMD Rule 1144 applies to specified users, manufacturers, and suppliers of metalworking fluids and direct-contact lubricants within the district. Facilities in the region should review the current rule and related recordkeeping requirements.
Measurable outcomes

Track performance using existing operating records

Purchasing records, disposal invoices, fluid tests, and system operating information provide a practical basis for measuring change.

New-fluid reduction

C.R.O.S.S. can reduce new fluid purchases by up to 85%. Compare equivalent purchasing periods before and after installation.

Disposal reduction

C.R.O.S.S. can reduce disposal costs by up to 90%. Track gallons, pickups, invoices, and the operating period represented.

Contaminant removal

C.R.O.S.S. removes 99.75% of tramp oil and particulate by volume.

Waste profile

Track the quantity and classification of each waste stream. Generator category depends on all hazardous waste counted for the facility during the month.

Generator categories apply only after the waste determination. Federal categories are based on total hazardous waste generated during a calendar month, with additional rules for acute hazardous waste and possible differences under state programs. Reducing one waste stream may affect the total, but equipment alone does not determine generator status.

Contamination control

Prevent coolant failure before it happens

Manage the contaminants that support bacterial growth and shorten usable coolant life.

Free oil, mechanically dispersed oil, and suspended solids feed bacteria and contribute to odor, shortened coolant life, poor machining performance, and higher maintenance costs. Filtration and oil separation remove these contaminants. The optional ozone system replaces routine biocide dosing with automated bacteria control and odor neutralization. For additional technical guidance, read the tramp oil guide and the coolant management guide.

Performance records

Use consistent records to measure improvement

Define the baseline, operating period, and measures before comparing results.

Fluid purchases

Track concentrate and mixed-coolant purchases over equivalent production periods.

Disposal volume and cost

Track gallons, pickups, invoices, waste profiles, and the operating period represented.

Fluid and system condition

Maintain the fluid-test and system-service information used by the facility's coolant-management program.

Results depend on the fluid, operating load, current practices, and selected configuration. An EdjeTech engineer can review the application and system requirements. Discuss your application →
