Mom always said to take your vitamins, and now it looks like she was right.  A good dose of vitamin B12 could be the key to cleaning up thousands of sites contaminated by solvents, particularly industrial degreasers and dry cleaning chemicals known as trichloroethylene (TCE) and tetrachloroethylene (perc).   These are two of the most common ground contaminants in the U.S., and when they get into aquifers, they are among the most difficult to remediate.  All that may be about to change.

Saving the tiger has become an issue fraught with much discussion — and much of it is ill-informed and misleading.  On the one hand are the tiger-farm lobby and the so-called “believers of free-market economics” such as John Stossel (ABC 20/20) , Terry Anderson (PERC) and Barun Mitra (Liberty Institute).  They want to lift the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) ban and favor open trade in tiger-parts.  They cite the apparent failure of the ban as the primary reason for lifting the ban.  Their arguments, they say, derive from free-market economics.  On the other hand are numerous (possibly insignificant because they lack the voice) individuals who, lacking voice, have opted for the exit option and have modified their behavior to save the most charismatic of animals, the wild tiger.  Alongside are many governments and many, many NGOs that struggle to save the tiger from extinction, that struggle to keep our world one species richer and which work to enable our future generations to look at the king of the forest, the tiger, in reality, not just in picture-books.  Apart from humane motives, their arguments are supported by economists, sociologists, zoologists, conservation-biologists, etc.

There are alternatives out there. Wet cleaning technology was introduced in the mid 1990’s and doesn’t require any solvents. It is garment specific, and uses soap and water in “smart” washers and dryers to clean clothes, which are then finished, or pressed accordingly. Some garments are also handwashed depending on the fabric.

Other than wet cleaning there’s liquid carbon dioxide, which uses captured CO2 in the cleaning process and is a lot less toxic than conventional dry cleaning. A Consumer Reports comparison found the CO2 cleaning method achieved better results than wet cleaning or conventional dry cleaning.

However, when taking something to a professional cleaner, always ask if you’re unsure if their method is safe for your garment. And while there are an increasing number of green cleaners popping up, they aren’t available everywhere just yet.

You can avoid the cleaners altogether and hand wash your garments at home. While the U.S. Federal Trade Commission’s Care Labeling Rule insists that ‘”Dryclean Only’ is a warning that the garment cannot be washed,” depending on the fabric, you can wash some garments labeled as such. The FTC’s Care Labeling Rule also says that clothing only has to carry a washing instruction or drycleaning instruction - even if both are acceptable for that garment.

When washing garments home, hand wash using a mild detergent and cold water. Don’t wring or twist the fabric and lay it flat to dry. Keep in mind that not all “dry clean only” garments can be washed. If you’re unsure if it’s best to take it to a cleaner.

California will ban perchloroethylene - or perc, the toxic solvent used in dry cleaning - by 2023.

The California Air Resources Board has already begun phasing out the widely used chemical by prohibiting the sale of new machines that use perc.

As with any new regulation there is some resistance from the dry cleaning industry. They say smaller operations could be forced out of business, and many will have to pass along the costs to consumers.

However, there are non-toxic alternatives already in use at green dry cleaners across the country. The most wide-spread alternative is a process called "wet cleaning." This method uses less energy, and new machines cost less than traditional perc machines.

According to an article in the LA Weekly:

"There are four perc alternatives being used in Southern California: hydrocarbon, GreenEarth solvent, CO2 and professional wet cleaning. Hydrocarbon cleaning uses synthetic hydrocarbon solvents in a machine similar to that used in traditional dry cleaning. It’s nontoxic, but the AQMD says it contains volatile organic compounds (VOCs) that release into the air and mix with other pollutants to form ozone smog. Which means it’s a lot better than perc, but still does damage to the environment."

"The most widespread method seems to be professional wet cleaning, a German process developed in 1991, which uses nontoxic biodegradable soap and water and is said to get clothes cleaner than perc cleaning because it attacks water-based spots and smells (i.e., the majority of the stains that need cleaning). Even better for business owners, computerized wet-cleaning machines cost $3,000 less than traditional perc machines and users have reported saving up to 45 percent on their electricity bills. Plus, they don’t have to pay for toxic-waste removal, so there are more savings to be had."
