Why we are here. This is the Charles River, recovered from several centuries of abuse. If you fell into the Charles 30 years ago, you were rushed to the hospital and given several injections and monitored in case you became sick. Like many rivers in our area, this one received waste from industries and towns. Industries included manufacturers and finishers of textiles, metals, leather, felting and hats, paper, printing, electronics and medical research. Today the Charles is swimable, which means it is clean enough to drink. Its waterfront is alive with activity, contributing to the quality of life of its human and wild communities.
2/3 of firms reported savings - $ and/or EH&S We look forward to seeing if companies are still finding value in the process, in particular materials accounting. Expect that they might feel differently 10 years later – e.g., now that the low hanging fruit has all been plucked. In fact, it was in response to industry complaints about diminishing returns on TUR planning that led to a significant amendment to the Act in 2007.
Examples of TUR Solvent substitution in washing and degreasing Cyanide replacement in electroplating baths Hydrocarbon-based inks replaced with water-based inks Dry-process coatings replacing wet-process coatings Installing energy- and water-conserving pumps and motors Installing automated pressure and temperature controls to reduce leaks and spills
Chemicals: Phosphoric Acid Sulfuric Acid Nitric Acd Sodium Hydroxide TCE VOC in paints (Butyl alcohol,MEK, Toluene,Acetone) Water soluable nitrates produced during neutralization of nitric acid Refrigerants CFC – 12, CFC-22
Why be interested in the Massachusetts TURA Program? Here is a quick look at what firms have achieved under this program. (details will be part of tomorrow’s session) INNER TITE Makes: Fabricated metal prouducts INNER-TITE Corp. is the world's largest manufacturer of the highest quality meter locking devices, meter seals and a host of mechanical accessories sold exclusively to utility companies TUR Technique: replaced its existing parts degreasing equipment with two entirely enclosed Forenta ｮ degreasing units. LIGHTOLIER MAKES: Lamps, fabricated metal, metal finishing See handout VH BLACKINGTON MAKES badges, service pins TCE cleaning operations were replaced with an aqueous cleaning system using 都 imple green crystal cleaner. � Approximately 45 gallons of water-based cleaner is used annually, achieved by carefully monitoring the bath chemistry and ultra-filtering the cleaner weekly for reuse. In addition, a small in tank filter, an oil skimmer, and conversion to compatible water-based pressing and stamping oils, made the new aqueous cleaning system more efficient. Changes were then made to the company 痴 bright dip operations reduced the copper and zinc loading to the wastewater by 85 percent. These changes include chemistry, metal recovery, improved process management, and the installation of drag-out tanks and a closed-loop system for rinsing operations. reducing the size of the plating tanks (from 60 gallons to 10 gallons), decreasing the concentration of cyanide used in the plating bath, and replacing the cyanide used in one specific process with less toxic sulfuric acid and phosphoric acid. These changes, along with switching from a 2-stage to a single stage cyanide desamount of sodium hypochlorite (bleach) used by 75 percent. The new Nitrogen/Hydrogen furnace system was paid for in 3 years from savings in fees, chemical disposal costs and other operating costs . OLYMPIC MNF MAKES: Screws
One industry supply chain workgroup is… 10 million lbs of lead and lead comp used in MA in 2000 more than 8 mill in plastics and resins – PVC etc. 3-1/2 mill used in coating of wire and cable In add’n, industry uses phthalates, BFRs, antimony, other heavy metals as stabilizers, FR, pigments, etc.

TUR planning identified the option of installing a electrolytic regeneration system to the cupric etch line, resulting in:
fully eliminating the use of hydrogen peroxide
a 90% reduction in the use of hydrochloric acid
recovery of 42,000 pounds of copper each year
a two-year pay-back of the $110,000 investment for the regeneration unit
