Chlorinated Chemicals
Safety & Environment: Material Safety Data Sheet (MSDS) Info Check your label or Material Safety Data Sheet, especially for chlorinated chemicals. Mixing this chemical family with other waste usually presents disposal problems. And, worker exposure limits to methylene chloride has been reduced from 500 parts per million to 25 parts per million).

Cleaners
Alternative Solvent Degreasers These degreasing and cleaning solvents are marketed as alternatives to halgonated solvents—especially chlorinated solvents. In some cases, these solvents require more time or stronger physical action for cleaning surfaces. All have lower rates of evaporation and drying than the chlorinated solvents they replace.

Cleaners Bolger Printing switches to bio-based solvents for press cleanup.

Emulsified Oil and Water Separating Products Aqueous cleaning solutions can be contaminated by the build-up of emulsified waste oil. This oil can decrease the solution's cleaning capability. Separating oil from the water is an effective technique for extending the usefulness of process fluid or in pre-treating the wastewater prior to sewering. MnTAP maintains this list of products for separating emulsified oil and water solely as a service to Minnesota companies.
