Living plasticfree sometimes means going alternative. Trying different things. There are many kinds of different alternatives talked about out there in Google land, some credited with the most fantastic attributes. But before you reach for the bicarbonate of soda and depend only on vinegar to sanitizer your kitchen, it might be worth investigating a little further.
This series of posts looks beyond the claims and tries to assess if these alternatives are indeed that great or even that greener in the long run,
Raw Materials or ingredients
You might need to make plasticfree alternative products.
Bentonite clay was first found in about 1890 near Fort Benton, Montana.
It is derived volcanic ash.
It consist of smectite minerals, usually montmorillonite
montmorillonite is named after a deposit at Montmorillon, in Southern France.
Other smectite group minerals include hectorite, saponite, beidelite and nontronite.
The presence or not of these minerals affect the value of the clay and of course what it can be used for.
high-grade natural sodium bentonite is found in
western United States in an area between the Black Hills of South Dakota and the Bighorn Basin of Wyoming
the Tokat Resadiye region of Turkey.
Mixed sodium/calcium bentonite is mined in
Greece, Australia, India, Russia, and Ukraine.
U.S. Mississippi and Alabama. Other major locations producing calcium bentonite include New Zealand, Germany, Greece, Turkey, India, and China.
Bentonite deposits are usually extracted from quarries.
Extracted bentonite is solid.
It is crushed and, “if necessary, activated with the addition of soda ash (Na2CO3).” Don’t know how or why but soda ash is also known as washing soda. You can read more about that here.
The crushed material is dried till the moisture content is around 15%
Depending on what it is going to be used for the bentonite may be
sieved resulting in granulesor
milled into powder
purified by removing the associated gangue minerals, or
treated with acids to produce acid-activated bentonite (bleaching earths),
treated with organics to produce organoclays.
In 2011, the U.S. was the top producer of bentonite, with almost one-third world share, followed by China and Greece
Bentonite presents strong colloidal properties and its volume increases several times when coming into contact with water, creating a gelatinous and viscous fluid. The special properties of bentonite (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications.
“The real benefit of bentonite clay is that it is abrasive enough to remove the plaque but not so much so that it will do damage to your enamel,” Graves says. Like charcoal, it may also help raise the pH of your mouth, making it more challenging for bacteria to grow.
