Silicone is indisputably safer for human health than plastic, which is a petroleum-based material commonly containing estrogen-mimicking chemicals like bisphenol-A (BPA). Doctors, scientists and regulators point to a wide array of health problems stemming from BPA and other environmental toxins that are endocrine disruptors.
When it comes to the environment, silicone is highly durable and more ocean friendly than plastic. Silicone, which is made from silica found in sand, is much longer lasting than plastic in the environment as well as while being used in products. Silicone endures extreme fluctuations in temperatures - from very cold to oven hot - without melting, cracking or otherwise degrading.
By using silicone & glass, we can dramatically reduce our usage of single use cups. With more than 5 trillion pieces of plastic floating in our oceans, using less plastic & single us products means contributing less to this mounting mass of plastics and waste lost in our environment and poisoning our wildlife.
“I really speak for the ocean. If we continue business as usual, we’re in real trouble,” said world-renowned oceanographer Sylvia Earle who is the author of “The World is Blue: How our Fate and the Ocean’s Are One” and the impetus for a new Netflix documentary. “In the last 25 years, I haven’t been diving anywhere, even 2 miles under the sea, without seeing some form of our trash, a lot of it plastic.”
Silicone resists oxidative deterioration (normal aging) for decades on end. In fact, studies have shown that silicones thrive on challenges, including exposure to extreme heat and cold, harsh chemicals, sterilization, rain, snow, salt spray, ultraviolet radiation, ozone and acid rain, just to name a few.
Consumer advocate Debra Lynn Dadd conducted her own research into silicone rubbers and says silicone “is not toxic to aquatic or soil organisms, it is not hazardous waste, and while it is not biodegradable, it can be recycled after a lifetime of use.”
Local recycling services are expanding the range of materials they collect every year, but if you can’t find a local spot to recycle your silicone lid and sleeve, then we’ll take it back and make sure it gets recycled on your behalf.
If disposed of at a landfill for incineration, the silicone (unlike plastic) is converted back into inorganic, harmless ingredients: amorphous silica, carbon dioxide, and water vapor.
When plastic, an organic material made from petroleum, is lost in the environment, it breaks down into micro-fragments which contaminate our lands and oceans as well as the animals living there. The estrogen-mimicking chemicals are then spread throughout the ecosystems, including oceans and land masses.
Additionally, because plastics are more prone to breaking down into little bits, wildlife often mistakes the bright colorful bits of plastic trash for food. The plastic “food” is poison and blocks their digestive systems, often resulting in death.
Still curious about the benefits of silicone as compared to plastics? Silicone is also odor and stain resistant. It’s hygienic and hypoallergenic with no open pores to harbor bacteria making it perfect to drink from.
The key to being a careful consumer is to only buy high-quality silicone that’s food safe. Not all silicone is created equal. To reduce costs, some manufacturers add fillers to the product. Luckily there is a simple way to tell: pinch and twist a flat surface on the item. If white shows through, the product contains filler. Pure silicone, like the lids used in our Wave Cups collection, does not change color when twisted.
