Waste Stream Targeted Blanket/Roller Wash - VOC emissions
Original System VWM Met Blanket/Roller Wash for Metro presses. This product is an oil-based solvent blend with a VOC content of 7.2 lb/ gal. VWM Metwash was used with Goss Color-liner, 4-high configuration cold-Webb Offset Presses (non-heat set). Employees dispersed the cleaner from a 55-gallon drum into pint buckets without lids and the product was applied with cloth wipes to clean the blankets and rollers.
New System
(with P2 Modifications)
Varn Bio-News Concentrate Biodegradable Blanket/Roller Wash is a water-based detergent blanket wash for water-based newspaper inks. Contains less than 5% of the VOC content of standard washes 0.32 lb/gal. Bio- News is pumped from a 350-gallon covered, reusable tote into 5-(30) gallon stainless steel tubs on wheels. Bio-News is pumped from these containers into an empty tub with cloth wipes for cleaning.
Cost Savings
Initial Equipment Cost None
Material Cost Savings 350 gallons of Varn Bio-News is used every 9 weeks @ $4.50/gallon or $9,100/year. Bio-News is diluted with water 6:1 while VWM is used as a concentrated solution. 350 gallon of VWM Wash was used every 4 weeks at a cost of $3.50/gallon or $15,900/year. This is a cost savings of $6,800/year!
Major Benefits Cost savings of $6,800 per year!
Reduced VOC emissions from blanket/roller washes by ~31,000 lb/yr or 95%!
Positive business image.
Improved worker health and safety.
Employee satisfaction with the use of a less hazardous, low odor blanket/roller wash.
Cleans better - new product removes solvent soluble and water soluble glaze.
Reduced potential for accidents, spills from product transport.
Obstacles Stronger solvent such as VWM is still required to clean some parts such as ink pans.
Cleaning with Bio-News requires slightly more time.
