[pagebreak:Cleantech Gets Dirty] It’s been a bad few days for biodiesel.
The penalty settled a lawsuit filed by the state’s attorney general, Tom Miller, claiming the plant didn’t pretreat its wastewater and sludge to acceptable levels before discharging it into the city’s treatment facility.
The lawsuit also claimed that after Iowa Falls notified Cargill it had reached its waste limit, the company -- along with a family-run waste-treatment company called Mort’s -- dumped 135,000 gallons of sludge, breaking land-use requirements and killing more than 500 fish.
The biofuels industry already had plenty of challenges, including shrinking margins and canceled plants. D1 Oils, a U.K.-based biodiesel company, is set to cut about 30 jobs, according to Greenbang. And that’s after Seattle-based biodiesel firm Imperium Renewables in January cut its staff and delayed plans for an initial public offering.
But the unwanted attention for pollution has some industry watchers wondering what the fallout will be for an industry capitalizing on being green.
Amber Thurlo Pearson, a spokeswoman for the National Biodiesel Board, said Cargill and Alabama Biodiesel’s polluting issues are rare -- occurring at only two of the more than 170 biodiesel plants operating in the United States.
"We hope consumers are discerning enough to not let a couple of bad apples spoil the whole bunch or the whole thought of biofuel," she said, adding that the trade association doesn’t condone polluters.
How Green is Your Greentech?
Still, there’s some fear of spillover.
After all, biodiesel isn’t the only green technology to come under environmental fire recently.
According to the Washington Post on Monday, Chinesesolar-silicon maker Luoyang Zhounggui, which sells silicon to customers like LDK and Suntech Power, was found dumping toxic waste in its homeland.
And ethanol has faced opposition from critics who argue that using farmland for fuel crops will jeopardize the food supply and could have unforeseen environmental effects (see Lester Brown Talks Smack About Ethanol and this Environmental Defense report).
"Ethanol has been blasted for months now," said Michael Tian, a Morningstar equity analyst.

Tian said such controversy could eventually turn the public against some biofuels, resulting in the erosion of supportive legislation, such as the 51-cent-per-gallon subsidy paid to ethanol producers.
But more stories like those in the New York Times and Washington Post could be on their way.
After all, an industry capitalizing on being green is particularly vulnerable to criticism for environmentally unfriendly behavior -- and intentional polluting is equivalent to a cardinal sin.
Whether companies are creating solar cells, producing biofuels or running wind farms, they still are running businesses, said Joel Makower, executive editor of GreenBiz.com.
"You are never going to have a 100-percent perfect record in terms of ethics and integrity," he said.
