2020 Findings

Catch of the Day

Each Seabin and LittaTrap™ collects a slightly different quantity of debris each day, depending on a wide range of factors including the location of the marina it is installed at, weather conditions, and more. Here's how our devices did on average across all our participating sites. 

 Remember - this data is 



The longer the devices stay in the water, the more plastic they collect. We have also been finding lots of small hard fragments, foam and film (both of which are very light), so the overall weight of the catch is much smaller than you might think. 

Lake By Lake

The Great Lakes Plastic Cleanup is collecting plastic from all across the Canadian side of the Great Lakes (check out our site network here!) As we collect more and more data, we'll be building up an increasingly detailed 'plastic profile' of each of the lakes, mapping trends for the different types and relative amounts of plastic in each. 


Hover over the name of a lake to find out the top three types of litter we've found at our sites there this season!
