Organisers of Sydney’s Mardi Gras Parade have announced they're phasing out the use of single-use plastics, including glitter.

Instead, organisers are encouraging floats to make use of “fairy lights, fluorescent paints and fabrics, lanterns and other light-reflecting materials.

Stephen Cotton, a chemical engineer who has helped to create bio-glitter says that compostable and biodegradable glitters are a part of the solution in tackling plastic pollution.
