Cleaners

Celebrate Success: Despite increases in production, Dana Corporation's Spicer Clark-Hurth Off-Highway Components Division in Plymouth eliminated hazardous organic degreasing solvents and several cleaning products used for building maintenance. These and other pollution prevention initiatives resulted in a 98 percent reduction in hazardous waste generated, $200,000 annual savings in reduced chemical purchases and $24,000 annual reduction in hazardous waste disposal costs.

Clean Up Your Printing
Vegetable-based and citrus-derived cleaners are on the menu of alternatives for printers wanting to pass on petroleum-derived chemicals—like toluene, xylene and methyl ethyl ketone (MEK). Used to clean printing equipment, those chemicals are all hazardous air pollutants (HAPs), Toxic Release Inventory (TRI) reportable and are classified as hazardous when they are a waste.

Bio-based alternatives contain no petrochemicals. They are considered nonhazardous and have lower regulatory costs due to their lower volatile organic compound (VOC) content.

Bolger Publications in St. Paul is using bio-based cleaning solvents to clean its presses. Because the press wash is vegetable oil based it is highly biodegradable and very safe to use. No protective equipment or special storage is required. Even the shop towels used with this wash are considered nonhazardous.

"We've been using the cleaner for five years and it works great," said Charlie Bolger, an executive officer for the company. "It's very popular with employees. They are happy to use products that are environmentally friendly." Hazardous chemicals no longer come into contact with the worker's skin and there is no foul odor. Less press wash is needed, saving Bolger at least $2,150 a year. Also with the bio-based press wash, they generate only one-tenth the amount of waste as with the petrochemical wash.

Ask your printers if they are using biochemical-based cleaning solvents and ink additives.

  • Seek out the least hazardous cleaning products for your needs.
  • For cleaning and degreasing applications in manufacturing facilities, explore natural solvents derived from citrus or pine oils (such as d-limonene), soybean oil or lactic acid to replace petroleum-based solvents.
  • When evaluating cleaners for building maintenance, consider:
    • Choosing cleaners with a phosphate concentration of 0.5 percent or less by weight.
    • Preferring products with a neutral pH.
    • Looking for concentrated formulas that work in cold water.
  • Labels may not provide enough information. Verify ingredients with the vendor.
  • Suggest that staff experiment using less product than the manufacturer recommends to find the minimum amount satisfactory for each use.
