How Do you Vacuum Plastic from a Beach?

Kamillo Beach in Hawaii has been called "Trash Beach" because of the large amount of small plastic trash on the beach. Engineers from Canada created a vacuum cleaner type machine called Hoola One. Because of the small size of the plastic, it's hard to separate it by hand. The machine sucks up the mixture of plastics and sand and then separates the products by buoyancy when water is added. The plastics float and the sand sinks so they are separated.  The machine can clean more than 17 kg of sand per minute. This  machine was developed for a class project at the University of Sherbrooke and was donated to collect the plastic trash on the beach. Although it will help deal with some of the issues of microplastic on this beach, the big issue is still the consumption and management of plastic and we must consider how to reduce, reuse and recycle.
