I let most of the stuff on this list float by, but Nathan, your comments piqued my interest. So, I did some research and found the simple green's Material Safety Data Sheet. (http://consumer.simplegreen.com/cons_msds.php) Here's what it had to say about putting simple green in the soil:
Biodegradability: Simple Green is readily decomposed by naturally occurring microorganisms....Per OECD Closed Bottle Test, Simple Green® meets OECD and EPA recommendations for ready biodegradability.
In a standard biodegradation test with soils from three different countries, Butyl Cellosolve reached 50% degradation in 6 to 23 days, depending upon soil type, and exceeded the rate of degradation for glucose which was used as a control for comparison.
Environmental Toxicity Information: Simple Green® is considered practically non-toxic per EPA’s Aquatic toxicity scale. --
Seems like as cleaners go, this stuff is pretty benign, which I think is why Bicas and a lot of other places use it. The main active ingredient is butoxyethanol, which decomposes in the environment within a few days and has not been identified as a major environmental contaminant. It is not known to build up in any plant or animal species. And curiously, simple green is the substance used to clean the oil slick off of sea life when oil tankers spill their muck into the ocean.
I can't imagine that butoxyethanol is what makes Bicas' mesquite tree grow...I'd bet that its all the extra water its getting...desert trees love to be watered.
cheers,
Ian

Oh my God... that is so bad for the ground (and ground water) and surface runoff when it rains.
Most communities have household hazardous waste collection facilities, just for these types of chemicals that are dangerous, bad for the environment, and they don't want in the landfill.

well, we here at bicas use a sink which drains into a bucket. the used simple green usually ends up in there and then we pour the bucket, when full onto our mesquite tree in front. i never would have thought but we have been doing it long before i was involved here. the tree loves it and has grown from just a 4 foot shrub into a full grown 25 foot tree in 5 or 6 years. maybe simple green, grease and hand cleaner act as a growth hormones or something. also we try to encourage that people first dilute the easy green, use minimal amounts of the stuff if soaking parts is absolutely necessary and also reuse it if possible as many times as we can. troybicas

Ah, friendly simple green. Such a nice name. Is there anything you can do to this stuff to feel better about disposing of it. What do you guys do? .
