Add-on carbon adsorption or refrigeration units can recover valuable solvent. Equipment can also be modified to enhance heat and water conservation. Extract solvents from filters as thoroughly as possible. Gravity drainage and cooking are commonly used techniques. Use on-site recovery techniques to make solvents reusable.
Distillation is a commonly used method of on-site recovery.
If the solvents cannot be made reusable, try to find a way to recycle them. One possibility for accomplishing this is to purchase solvents from a company that will pick up and recycle the spent solvent. Handling Other Wastes Waste reduction applies to all waste generated, not just regulated hazardous waste. In developing a waste reduction program, don t forget to include the nonhazardous wastes being produced within the shop. Every waste is a potential candidate for reduction, reuse, or recycling.
