A sponge is a sponge right? Absolutely not! All Regular Cleaning Sponges are made from Polyurethane, a petroleum-based ingredient, which means, conventional sponges are made from oil-based plastic. Not very green, huh?
But, the worst is yet to come... Many Supermarket brands claim their sponges won't hold odours, and "contain an Anti-Bacterial treatment to keep them fresh for longer", and while this is true, that ' Anti-Bacterial treatment' is an extremely dangerous chemical called Triclosan - but they won't tell you that...Triclosan, is an antimicrobial agent (and pesticide) which reduces or prevents bacterial contamination, and has been linked to cancer, decreases in the levels of some thyroid hormones, contributes to making bacteria resistant to antibiotics, potential of developing skin cancer after a long-term exposure, developmental toxicity and skin irritation. This chemical has also made its way into 60 percent of American waterways, and an Australian Report - The Journal of Environmental Quality JEQ-2014-01-0012-TR.R2, was conducted to gather research about Water Contaminants, Hazard Quotients, Micropollutants, Surface Water, TrOC and Water Quality, and according to this report, Australian Waterways Triclosans levels were considered at a hazard quotient, at 35% in NSW alone, not including the rest of Australia.
Triclosan is wreaking havoc on marine life. How do you feel about tossing that sponge in the trash now?
Then there’s the waste factor. A stinky sponge is not something you are going to be keeping for a long time, so we chuck them out—and often. From an eco point of view, that means lots of garbage heading to the tip tube stored as landfill.
