Most glitter，which is made up of tiny pieces of plastic，is a huge danger to the environment. "Everyone talks about the mountain of plastic floating in the ocean.You can grab empty bottles from the water，but with tiny pieces it's impossible，" says Victor Alvarez，a chemical engineer who sell an eco-friendly alternative to glitter.
   In the early 2000s，Alvarez worked for Mercedes-Benz in Germany，where he became fond of any technology that protected the environment.A few years after leaving Mercedes-Benz，he founded Blue Sun International in Miami，which makes specialty ingredients for the skin and haircare industries.
   Glitter is a popular ingredient in cosmetics，such as eye shadows and lipsticks.So Alvarez began researching an alternative that didn't contain plastic to make his products safer for the environment.That's when he came across Ronald Britton Ltd.，a company which had developed a plastic-free，biodegradable product called Biogljye.aiter.It is made from regenerative cellulose（纖維素）sourced from hardwoods，primarily eucalyptus.Alvarez worked with the company to become the first retailer to sell Bioglitter in America.In 2018，he formed Today Glitter in order to sell the biodegradable glitter directly to consumers through its website.
   Today Glitter sells two kinds of biodegradable glitter-Bioglitter Sparkle and Bioglitter Pure.Both are almost plastic-free and can biodegrade in a short time.Meanwhile，they are as shiny as regular glitter.All these products are third-party tested by TUV，an international organization that provides testing and certification for compostable and biodegradable products.
   Despite its benefits，the hardwoods needed to make biodegradable glitter cause it to cost about twice as much as conventional glitter.A small glass container that contains just 6 grams of Bioglitter costs ＄10，while the same amount of regular glitter could cost at least half that amount.Alvarez expects the price will come down over time.He also expects the company's sales to cross ＄1 million next year.But more importantly，Alvarez says，his main goal is to effect a meaningful change.
