Use solvent cleaning only when necessary. Many modern fabrics, including silks and wools can now be washed in water.
Plan loads so that only full batches are handled.
Recently the EPA has issued new rules to assure dry cleaning emits less air pollution. Business size and the type of equipment used will determine which of these activities will be required, but the concepts can be beneficial to all. Collect and recycle spent solvent by redistilling it in a separate still. Capture and reclaim solvent vapors by using refrigerated condensers or a carbon filter in the vent. Replace old equipment with modern, more efficient dry-dry machinery in which clothes are put in dry and taken out dry.
