Holy awesome! Some high school kid in Canada came up with a way to bio-digest plastic shopping bags. For a freaking science fair! Amazing. 500 billion plastic bags are produced worldwide every year, and they take up to 1,000 years to decompose. We’re all aware of the fact that plastic bags pose a lot of problems – they clog up landfills, choke marine life and are seen floating in water far too often. Finding a way to get rid of them is huge.
From The Record:
Daniel Burd’s project won the top prize at the Canada-Wide Science Fair in Ottawa. He came back with a long list of awards, including a $10,000 prize, a $20,000 scholarship, and recognition that he has found a practical way to help the environment.
Daniel, a 16-year-old Grade 11 student at Waterloo Collegiate Institute, got the idea for his project from everyday life.
“Almost every week I have to do chores and when I open the closet door, I have this avalanche of plastic bags falling on top of me,” he said. “One day, I got tired of it and I wanted to know what other people are doing with these plastic bags.”
The answer: not much. So he decided to do something himself.
He knew plastic does eventually degrade, and figured microorganisms must be behind it. His goal was to isolate the microorganisms that can break down plastic — not an easy task because they don’t exist in high numbers in nature.
Daniel ground the plastic bags into a powder and mixed it with ordinary household chemicals, dirt, yeast and tap water to encourage microbe growth. For three months he allowed the concentration of microbes to increase, and put the culture into three flasks with strips of plastic bags. Six weeks later, he found that the bags weighed an average of 17 percent less. Not satisfied with that result, he continued working on the solution until he isolated his most effective strain of plastic-eating bacteria and got a result of 43 percent degradation in 6 weeks.
What a cool example of how innovation can come from the most unexpected places.
