PORTLAND PRESS HERALD • October 30, 2025
This year, all of the boats at the Port Harbor Marine’s five Maine locations will be wrapped in BioWrap, a single-use biodegradable plastic boat wrap made by a Rhode Island company called Bioaqualife. The pale green shrink wrap costs about 20% more than standard wrap but claims to be an eco-friendly alternative. Each year, as much as 1.5 million pounds of plastic from Maine boat wrap ends up in landfills, where it breaks down into microplastics and releases harmful chemicals into the environment. BioWrap is marketed as being able to be sent straight to the landfill, where it reportedly breaks down into water, biogas and carbon after 4.5 years and does not leave traces of microplastics or heavy metals. Experts question whether the new kind of wrap is as beneficial as it seems. Margaret Sobkowicz Kline, a plastics engineering professor at the University of Massachusetts, said it would be better to focus on reusing or recycling the oil-derived plastic wrap so it doesn’t end up in a landfill. Benjamin Holloway, the owner of The Shrink Wrapper based in Woolwich, said his company recycles about 15,000 pounds of single-use plastic wrap per year.
