23 Mar 2010 Sustainable Dishwashing: No More Plastic

Have you scrubbed a pot using one of those green scratch pads lately? Most of us have. Did you know that they are made of oil-based plastic that breaks down as you scrub and those small pieces go down your drain, into the municipal water treatment, are filtered out and end up eventually in the Bay and ociean? Along with microscopic broken bits of plastic bags and bottlecaps they become part of fish and crustacean diets. Plastic has now become a defacto part of seafood flesh - yum, yum.

Solution? Loofah & agave scrubbers. Loofah (my sister grew some in LA one year) & agave are plants. Loofah can be purchased as a yarn if you have time to knit or crochet your own scrubber. 3M, just started making scrubbers from agave (found some at Target) but there are probably others (let me know in comments).The sponge part of the old double-sided scrubbers been natural sponge but with chemical dyes (bye-bye purple, orange, blue). The new sponges are made of recycled paper and natural fibers and have no chemical dyes.

I’m less enthusiast about the 3M soap loaded scrubbers. Soap is phosphorus free and scrubbers are from recycled plastic, but, again, plastic bits into the water stream. Their wipes are from bamboo, rayon (pulpy part of cotton plant), cotton & corn, presumably new material since recycled isn’t mentioned but all are compostable. Read labels & go online for details.

Remember, you don’t need to see scads of bubbles for a dish detergent to do its job. Though it seems counterintuitive, rinsing with cold water is best because bacteria thrive in warm (i.e. temperatures that our hands can handle) water but not cold.

Absorb grease and other food stuck to plate with old napkins, paper towels and put in garbage. Keep a strainer in the sinkhole. The more grease and food particles that go through your municipal water plant, the more energy they must use to clean your water.

11 Jan 2010 Recyling Your Media Waste & Techno Trash

Is part of your 2010 New Year resolution to go through and dispose of all those old videotapes, floppy disks, zip Disks, DVDs, CDs and jewel cases that you never want to see again? You may need to put out a few dollars for postage or services but there are some choices for doing this responsibly:

Disabled employees of the nonprofit Alternative Community Training (ACT) in Columbus MO grind up various smaller plastic items such as CDs, VHS tapes and jewel cases for resale to manufacturers who use recycled plastic. You can mail your trash using media mail rates ($6.95 for the first 20 lbs and 30 cents for each pound over that).

GreenDisk uses a network of non-profit organizations to process techno trash. They refurbish what we can and recycle the rest. Inkjet cartridges get remanufactured and, when possible, cell phones and some computers get refurbished. Material that has no further operating life is broken down to its smallest components (metals, plastics, etc.) and used in the manufacturing of new products. All of the material that GreenDisk collects is reused or recycled. No hazardous materials or obsolete components go overseas to be processed or disposed of. The cost here is the same as above.

If you live in the San Francisco Bay area you may be able to take it directly to a local Green Citizen center. They locate themselves near business centers to encourage businesses which produce so much of the techno trash. When my husband’s business moved in San Francisco last week, we just wheeled a couple monitors on carts a few blocks to the Howard St center.

If you’re active at your church or school, consider a drive to collect and return this trash. (Solicit some donations to cover mailing boxes and postage at the same time).

04 Jan 2010 Bisphenol-A (BPA) is Everywhere, including your toilet paper

That nice shiny paper that most receipts are printed on? BPA (or BPF) is likely-as-not an ingredient. We slip those recieipts in next to our currency in our wallets, slide our hands over them countless times as we rummage through our purses, pick them up to enter them in Quicken, then one more time to file, trash or shred them.

“When people talk about polycarbonate bottles, they talk about nanogram quantities of BPA [leaching out],” John C. Warner of the Warner Babcock Institute for Green Chemistry observes. “The average cash register receipt that’s out there and uses the BPA technology will have 60 to 100 milligrams of free BPA.” By free, he explains, it’s not bound into a polymer, like the BPA in polycarbonates. It’s just the individual molecules loose and ready for uptake.”

But thats not the end. Those duplicate check records? Carbonless credit card receipts? What if you’re a cashier handling them all day? Touched some food after handling the receipt? Ouch! Of course, many of us recycle those receipts, cool huh? Maybe not, it may be ending up in our recycled toilet paper. Is shredded thermal paper part of your composted fertilizer? Ooops.

Bill Van Den Brandt of Appleton papers point out that his company’s receipt paper (manufactured for NCR) is now BPA-free. This after after a lawsuit (NCR also named) for cleaning up PCB’s from the Fox River in Wisconsin) and subsequent change of ownership to employees.

“Attempts have been made to develop a thermal ink which reduces the problems associated with thermal papers by obviating the need to provide a thermal coating over the whole surface of the paper.” but this technology has not been perfected. I’ve got some receipts I can no longer read (though I really have no idea which technology was actually used).

Another option, the companies, TransactionTree, and AllEtronic emails a receipt to you (instantly) and you have 24 hour access to your receipts through their website. TransactionTree might also email you a retailer discount coupons & AllEtronic will soon have an iPhone app.

As worrisome as thermal printing paper is, the use of BPA in the packaging of many microwaveable convenience food products is even more so.

The sticking point is actually figuring out which manufacturers still use the BPA method and which stores buy paper from which mfg; data still outstanding. In the meantime, be aware. Don’t put thermal receipts in your paper recycling (or compost). Consider the electronic options, if available. Educate the stores you frequent. Decrease your use of microwaved convenience foods.
