By Jim Knowles

San Leandro Times

The East Bay Municipal Utility District recognized Hesperian Cleaners in San Lorenzo as a WaterSmart Business for its water efficiency.

Hesperian Cleaners owner Sung Lee says he wants to lead the way in the dry cleaning industry.

“I want to set an example, to become a leader in the industry so others will follow,” Lee said.

Lee’s cleaners went to a water-based cleaning system, instead of using solvents or other chemicals. But he says the German-built machines are very efficient in the way they use water, so he has reduced his water consumption.

Harmful chemicals all washed up at cleaners

California requires safer methods for dry cleaning

Thanks to a statewide ban, dry cleaners in the Bay Area are scrambling to green up their operations. In the first plan of its kind, the California Environmental Protection Agency approved phasing out traditional dry cleaning machines in January 2007. Many machines will be gone in a year and a half, and a series of Bay Area programs are lining up to help local cleaners through their difficult transition.

“The goal is to encourage cleaners to adopt wet cleaning or carbon-dioxide-based methods — these are the only two alternatives the state considers non-toxic and non-smog forming,” said Peter Sinsheimer, director of the Pollution Prevention Center at Occidental College in Los Angeles. Sinsheimer ran several workshops in the Bay Area this year, and says more are planned for 2009.

New technology sweeps across industry and may forever change your corner dry cleaner

By Douglas Fischer - STAFF WRITER
Tri-Valley Herald, Monday, July 30, 2007

SAN LORENZO -- No sign touts the pile of cash Song Lee spent to switch his modest dry-cleaning shop to green technology.

He simply pulled aside a long-time customer, a Berkeley police officer whose perspiration-stained uniform would be the bane of any cleaner, to ask if he noticed anything different. ``Yeah,'' Lee recalls the cop saying. ``It smells cleaner. There's no dry-cleaned smell. What'd you do? '' I spent $90,000 for you,'' Lee replied. Lee is part of a vanguard of clothing cleaners adopting new technology as California phases out the industry's chemical of choice, perchloroethylene, or perc, linked to a host of cancers, leukemia and other health problems. He's trying to get out ahead of a wave of green technology that threatens to wash away the mom-and-pop cleaner and reshape the industry.

Nowadays, there are nine Miele users (seven of whom attended the meeting) located in the vicinity that reaches as far south as Sunnyvale, which is in the heart of Silicon Valley, to as far north as Sacramento and up to the coast to Mill Valley.

Hesperian Cleaners…

Green for a Cleaner and Brighter Future

Danville, CA…With the world becoming more and more aware of the green initiative, people and businesses are looking for healthier options in their daily lives at home and in the workplace, to preserve the environment. To some degree, each and every single person can do his/her part in “going green,” whether it be as little as switching from using an old incandescent light bulb to an energy star compact fluorescent light bulb, to businesses converting entire systems and methods of operation to more environmentally sustainable ones. One such individual decided he wanted to make an impact on his family, his neighborhood, his employees and the environment, by completely switching his dry cleaning methods to a wet cleaning process.

Concerned by the potential health hazards associated with the use of perchloroethylene (PERC), a traditional dry cleaning chemical,
Hesperian Cleaners decided to go green. “I didn’t want to change it to another solvent or another type of chemical,” says owner Sung Han Lee. Therefore, five years ahead of the new mandated schedule to phase out PERC, Mr. Lee chose a new process called wet cleaning. Rather than switching to a “less bad” process using hydrocarbon solvents, Hesperian Cleaners decided to go with the only process that can be truly called organic. The wet cleaning process includes a computer controlled cleaning machine that uses a small amount of water with biodegradable detergent. It uses less water than other dry cleaning processes and, unlike most cleaning processes, does not generate any hazardous toxic waste.
