Clean Water Solutions
St. Louis, MO
Wash-water recycling system for truck washing
Clean Water Solutions found a way to turn Coca-Cola trucks from red & white to GREEN. Every two weeks, the maintenance facility was using 10,000 gallons of water to wash the 100-member truck fleet. The wash water which contained fats, oils, grease, grit and road salt was discharged to a sewer.
Eighteen months ago, Clean Water Solutions introduced a wash-water recycling system that uses advanced oxidation. The oxidation process breaks up the detergents emulsion with fats, oils and grease. The oxidation process serves as a pre-treatment process that enhances the capacity of the dissolved air flotation system. The entire process has low energy requirements and operation and maintenance costs. In the past 18 months, water use has been reduced 360,000 gallons; washing discharges to the sewer were eliminated and chemical use was cut 50 percent.
DuPont Performance Coatings
Fort Madison, IA
Resin wastewater recovery and minimization project
Three years ago, DuPont was faced with increasing costs on a growing hazardous waste stream resin process water. Also, very stringent effluent limits came into play. At the time, DuPont was disposing of more than 390,000 gallons per year of resin process water. Conventional technology could not effectively (technical or cost basis) address the challenge.
DuPont found a liquid-liquid extraction process that could separate the hydrocarbon resin from the water. The process uses a porous polymer that contains the extraction liquid within the pores themselves. In 2000, DuPont met or exceeded the discharge limits for 400,000 gallons of resin process water. Further, they were able to save more than $50,000 in the recovery and reuse of solvent.
DuPont met this challenge through developing excellent working relationships among their technical team, the Fort Madison treatment works and Iowa Department of Natural Resources.
National By-Products, Inc.
National By-Products (NBP) collects and processes upwards of 4 million pounds of farm mortalities, meat animal by-products and kitchen greases each week. Their existing package steam boiler burned natural gas and petroleum based diesel fuel. They found a 'new fuel' that produced fewer criteria pollutants than petroleum-based heating fuels.
NBP has found a viable alternative to improper disposal practices. They did not advance a new technology they know that burning animal fat and vegetable oil is not a new concept. They did add to the compendium of knowledge insofar as there had been little knowledge to design, set up and produce emission factor information on animal fat as boiler fuel. Current market rates suggest an annual savings of almost $37,000 over using No. 2 diesel fuel. Emission savings are present on the order of 5,800 pounds for nitrogen oxides; 41,000 pounds for sulfur dioxide and 1,100 pounds for carbon monoxide.
MidAmerica Energy Holdings, Inc.
Des Moines, IA
LED traffic lights in Davenport, IA
MidAmerica Energy Holdings Company (MEHC) believes responsible environmental management is good business, benefitting their customers and the quality in the environment. MEHC worked with the Davenport (Iowa) to change traffic signal lights from incandescent bulbs to light-emitting diodes (LEDs).
An LED light uses one-tenth the energy of a conventional incandescent lamp and lasts 8-12 years longer. By replacing the traffic signal lamp, the city should reduce its annual energy use by 2.1 million kilowatt hours, about $20,000. Less frequent need for lamp maintenance results in an annual maintenance savings of about $110,000. If all traffic signals in the United States were converted to LED lights, there would be an annual energy savings of 3 BILLION kilowatt hours.
The energy savings equates to an annual reduction of 3.5 million pounds of carbon dioxide; 11,000 pounds of nitrogen oxides and 6,900 pounds of sulfur dioxide.
Farm Machinery Manufacturer
In 1996, Thurston Manufacturing decided to reduce its level of air pollution. At that time, fugitive emissions included almost 24,000 pounds of hazardous air pollutants and almost 57,000 pounds of volatile organic compounds. Company officials set an ambitious goal to reduce both sets of emissions by 50 percent in five years. They had an intermediate goal for 30 percent reduction the first two years.
Thurstons workforce took a close look at their paint formulations and solvents. With changes they made, in the first 18 months they saw volatile emissions drop 38 percent and hazardous air pollutants decrease 50 percent. They continued their efforts and at the close of the five years, they had cut volatile emissions by 62 tons a reduction of 52 percent. Likewise, they made good on their pledge to reduce hazardous air pollutants by 31 tons, a 59 percent reduction.
Stores in Iowa, Kansas, Missouri & Nebraska
(Environmental Services Department,
River Falls, Wisconsin)
Target is an innovations leader in waste reduction. Their goal is to achieve zero waste. Company officials have actively worked with vendors to reduce product packaging. Target was the first major retailer to virtually eliminate excess packaging on clothing lines. Target routinely asks that manufacturers package with recycled content and that containers are recyclable. They conduct and publish annual self-assessments of their environmental operations. Target's 'De-Trashing Project' sets fiber recycling goals in relation to sales per store. They close the recycling loop by using recycled paper for much of their printing operations as well as offering products made from recycled materials.
Target stores collect paper, corrugated cardboard, batteries, aluminum, metal fixtures, shrink wrap, pallets, computers and more for recycling. The 56 stores in Region 7 recycled 2,900 tons in Year 2000.
EPA is pleased to recognize its Waste Wise partner, Target, with a general pollution prevention award.
