CTSA - Chapter 6: Additional Improvement Opportunities

Cleaner Technologies Substitutes Assessment (CTSA): Lithographic Blanket Washes

This chapter focuses on techniques which may be employed at lithographic print shops to prevent pollution, to reduce chemical consumption, and to minimize waste. Section 6.1 examines results from a pollution prevention survey, which asked lithographers to identify what activities they currently employ to achieve a more environmentally friendly workplace. The most common of these activities and their effects are presented. The pollution prevention benefits that result from changing workplace practices are discussed in detail. Section 6.2 addresses options for recycling solvents and the economic and environmental implications associated with such recycling. Methods for extracting solvents from press wipes are addressed, as are methods for treating spent solvents so that they may be reused. Solvent recycling and distillation systems are also discussed.
