In 2014, the world produced 311 tons of plastic. If the production rate continues, there will be 1.2 billion tons of plastic by 2050.  A new biodegradable plastic bag, SoluBag, may be the answer to replacing currently used plastic bags as it contains no oil derivatives and is not harmful to the environment.  This new plastic bag has gone on sale this month in Chile.  Roberto Astete and Christian Olivares, researchers from Chile, are behind the new biodegradable plastic bag.  The formula was discovered while experimenting with biodegradable detergent.  “The team used PVA, a polyvinyl alcohol that dissolves in water, as their chemical base and then replaced the oil derivatives to ensure the bag would degrade over time.”1. Oil derivatives in plastic bags are what cause plastic bags not to degrade, but remain in the environment and then cause serious problems with natural environments and marine life. The product that these Chilean researchers are using come from limestone.

The Chilean government banned the use of plastic bags in August 2018. “The main difference between traditional plastic and ours is that traditional plastic remains between 150 and 500 years in the environment and ours only lasts five minutes.  You can decide when to destroy it.”

The SoluBags dissolve in cold water. What remains is carbon, which has no effect on the human body.

A side benefit of the SoluBag is that it protects against asphyxia. The bag dissolves when it comes in contact with a person’s tongue or tears.  Existing plastic companies can easily produce these bags by simply changing their formula.  Pricing of these SoluBags are similar to the plastic bags currently produced.  Chile has launched this product in their country, however, testing on SoluBags has only just begun in the US.
