Putting Seabins on Toronto’s Waterfront – Capturing Litter and People’s Imagination

The story of a shared vision to raise awareness and reduce litter through research and creativity.

Have you ever noticed litter in or near the water and wondered if there was something more you could to do raise awareness of the problem while at the same time implementing a solution to tackle the challenge? This curiosity was what brought Chelsea Rochman and Susan Debreceni together in a partnership to tackle a global problem. It was just more than two years ago when Chelsea and Susan were inspired by the famous Mr. Trash Wheel in Baltimore and met up with a shared goal to bring a similar wheel to Toronto. Without a clue about how to do this, they began their journey.

At the time, Susan was working for Ocean Wise helping lead the Great Canadian Shoreline Cleanup and Chelsea was starting her career as an Assistant Professor at the University of Toronto in the department of Ecology and Evolutionary Biology. Together, they knew that having a Trash Wheel in Toronto would capture the public’s attention and become an incredible centrepiece for an education and outreach program helping increase waste literacy in the local community and beyond.

To get started, they reached out to the inventors of Mr. Trash Wheel in Baltimore as well as PortsToronto, who own and manage several areas of Toronto’s waterfront. Immediately upon reaching out, both groups responded to learn more. Shortly afterwards, Chelsea and Susan were joined by Dr. Rafaela Gutierrez, an expert in social science and waste management. These conversations quickly turned into a feasibility study to see if Toronto was a good location for a Trash Wheel. Quickly, Susan, Chelsea and Rafaela gathered a team of 25 undergraduate and graduate students who all shared the same passion for increasing waste literacy.  At the time, it was looking like the Don River would be the ideal location for such a device, but ultimately through the results of this study and many, many, many meetings and phone calls with a growing list of stakeholders, the team was struck with the realization that a Trash Wheel was not the best waste solution for Toronto at that moment in time.

Instead of calling it quits and throwing in the towel, they continued to brainstorm with PortsToronto about other waste capture options, including a Roomba like swimming vacuum, capture devices at the end of storm drains, litter skimming vessels and Seabins. Soon after, PortsToronto’s Sustainability Committee began an active discussion about Seabins and connected with the Seabin Project to learn more. Then, in the summer of 2019, two bins were installed in the Outer Harbour Marina.

Big and Little Plastics
An assortment of plastics were captured from Seabins in the Outer Harbour Marina.

It was only a matter of days into the initial Seabin trial when the bins were visited by dozens of curious visitors, generated several media interviews and removed 2000+ pieces of plastic from the marina. Everyone was thrilled and as a result we were off to the races and our Trash Wheel at the mouth of the Don River was turning into a plan for more Seabins along the Toronto waterfront.

In the early weeks of October, two additional Seabins were installed in Toronto’s Inner Harbour at Pier 6. On a cold and windy morning a group of local NGOs, the Ontario Minister of the Environment, the local Member of Provincial Parliament, and a Councillor of the Mississaugas of the Credit First Nation were brought together to celebrate the new bins. In front of the local group, the bins were introduced and demonstrated, and preliminary litter data from phase 1 was shared, all while enjoying hot coffee (in reusable mugs) and Beaver Tails (a famous and delicious Canadian pastry!).

This day was incredibly special and meaningful. It was not only a celebration of the new Seabins, it was also a celebration of how far our team had come and where we were headed. Over the last two years, our hard work and perseverance created a local community group –  the U of T Trash Team – a dedicated and passionate team that includes undergraduate and graduate students, postdocs and dedicated staff. The U of T Trash Team’s mission is to increase waste literacy in our community and reduce plastic in our ecosystems.

As a group, the team has developed new waste-literacy school programming, scheduled to begin this year at Grade 5 classrooms across the Greater Toronto Area. The team also runs community outreach programming – including two annual cleanups per year in collaboration with Toronto Region Conservation Authority and Ocean Conservancy. Additionally, the team focuses on solutions-based research – including a pilot project installing lint traps in 100 homes in a small community to divert microfibers from Lake Huron, and working with industry to achieve zero pellet loss to Lake Ontario. And finally, the U of T Trash Team is a proud partner with PortsToronto on the Seabin pilot to “litter”-ally trap trash on its way out to Lake Ontario, preventing it from contaminating our waterways, our fish and our local drinking water.

Cleaning up our Hidden Shorelines

We hosted our first ever ‘Urban Litter Challenge’ and here’s how the day went.

As you wander around the neighbourhoods of downtown Toronto it’s likely that the shores of Lake Ontario are the furthest thing from your mind, but the shoreline is closer than you think. That’s because we all live in a watershed, where creeks, streams and rivers lead to oceans and lakes. Here at the University of Toronto, a downtown and inland location, we are connected to Lake Ontario via storm drains, so it was the perfect location to host an International Coastal Cleanup and connect our local community to our local watershed. We dubbed it the “Urban Litter Challenge”.

More than just a typical cleanup
The morning started on campus at Hart House Circle, where a team of eager Trash Team volunteers gathered to set up for the day and greet student and community volunteers before grouping them into small teams. These teams were then encouraged to keep a record of what they found by recording their findings on data cards as part of the Great Canadian Shoreline Cleanup. These findings are important citizen science contributions that can be used to inform best practices for future waste management.

DataTabulationandcigbutts
Data cards kept track of what litter items volunteer teams collected.

We were also joined by friends and collaborators to set the tone for the big day. Bear Standing Tall opened the cleanup with an opening prayer, local City Councillor Mike Layton sent words of support for our team to share, and Geoff Wilson (CEO of PortsToronto) spoke about the importance of protecting Lake Ontario, including some exciting updates on their plans to install Seabins in the waterfront.  And with these welcoming words, our teams were sent off to clean!

What did we find?
Based on past cleanup experiences, we predicted some classic repeat offenders would top the list once again, and as it turns out our predictions were correct. Cigarette butts were easily the number one item found (>7,000!!), followed by miscellaneous scraps of paper, small plastic pieces, food wrappers and plastic bags. Honourable mentions included bottle caps, miscellaneous packaging materials, various personal hygiene items and coffee cups. One of the most unpredictable things about the cleanup was guessing how many people would show up, and we were thrilled with a turnout of 80 volunteers! Together, they removed more than 50 kg of trash from our local watershed, filling nearly 50 bags of garbage and recycling!

What made the day most memorable?
It’s always tricky to pinpoint the most memorable part of a day where nearly every moment was incredible, but there were definitely a few standout moments to share. Volunteer teams were encouraged to come up with creative names for their group and they sure did not disappoint, including such creations as the Trash Pandaz, Cigarette Butties, Alvin and the (crumpled) Chip Bags and Dumpster Defenders. Another great moment that happened throughout the day was when passersby expressed their thanks to our volunteers for keeping the neighbourhood clean. All in all, it’s safe to say that the most memorable part of the day for everyone was seeing just how big of a difference they could make in such a short timeframe.

We’re already counting the days until next year’s International Coastal Cleanup event, but there is no reason to wait 365 days to make a difference. Every day we wander our watersheds so this year we challenge you to clean a piece of your watershed everyday by removing one item of litter from a roadside, park or local creek. If someone asks you what you are up to, tell them you are cleaning the oceans and lakes, because no matter where we are, we are always in a watershed.

If you want to stay up to date on all things Trash Team, follow us here. See you at the next cleanup!

What Litter is Entering Toronto’s Outer Harbour Marina?

A preliminary look at what Seabins are collecting along Toronto’s waterfront.

This past August, PortsToronto installed two Seabins at Toronto’s Outer Harbour Marina and we visited them to count the litter they captured. This was done to help measure their effectiveness and better understand what litter is reaching our Great Lakes. Resembling underwater garbage cans, Seabins help clean the harbour by pumping water through a catch bag. This action removes, along with other contaminants, plastic litter greater than 2mm in length.

Although it was our first-time quantifying litter from Seabins, it wasn’t our first time counting and classifying trash. We’ve spent many hours over the past few years searching for plastic in an array of environmental samples. These experiences have taught us a lot, but one of the biggest takeaways is that plastic pollution is ubiquitous. With this in mind, we were prepared to spend the entire day counting; however, when we arrived at the marina, we were pleasantly surprised. Since we’ve both participated in community cleanups before, we expected to find large amounts of litter (as this was the trend for many cleanups in urban areas); however, upon arrival our presumption quickly changed. The water was clear and the docks were tidy… surely the Seabins wouldn’t have much to catch then, right?

Size definitions for ‘big’ and ‘little’ plastics: big plastics were’ bigger than or equal to the size of a nickel’ and little plastics were ‘’between the size of a nickel- and nurdle’ (represented by orange arrow).

Turns out appearances can be deceiving. Half a day later, we’d only finished the easy part: removing plastics larger than a nickel (what we classified as “big plastics”). It would take days to count all the “little plastics” too (those smaller than a nickel but equal to or bigger than a nurdle, small pre-production pellets used in the production of plastic products). Because of this, we decided to subsample and extrapolate the results. After another half day and some quick calculations, the results were in: nearly 2000 pieces of plastic between the two bins. Amazingly, it had all accumulated in less than 24 hours.

Much of this experience was surprising, from finding almost 2000 plastics in a seemingly clean environment to having a passersby ask us whether or not we’d found gold. (The answer, unfortunately, is still no). Overall, it was a rewarding learning experience, and a great chance to share our work with those at the marina. It was also a wonderful opportunity to learn more about how to mitigate plastic pollution – including microplastics. Together with other waste management systems, we feel Seabins are an effective form of technology to assist in protecting our bodies of water and are excited to see more innovative technology in the future.

How I spent my summer Vacation

A sampling of the unique ways some of our team spent their summer.

Summer is over and school is officially back in session, which means students are returning to the classroom and swapping stories about all the fun they got up to over the summer season. Tales of trips to the beach, vacations to exotic locations and new adventures in fine dining– so many stories to share! For the U of T Trash Team, we spent our summer vacation a bit differently. From exotic trips to study litter in Vietnam, many hours in the lab analyzing microplastic samples, to a variety of field work and outreach activities, we sure had quite the memorable summer. This is just a sample of what some of our team got up to.

Nick Tsui: Nick had the opportunity to wade (quite literally) into field work and meet with many groups (including industry, government, and academic stakeholders). His most memorable experience? Getting caught in 60mm+ rainfall doing fieldwork (without a raincoat!).

Rachel-Vietnam-3
Many new friends were made during Rachel’s time in Vietnam

Rachel Giles: Rachel joined Chelsea on a unique opportunity to visit Northern Vietnam and study litter and its impacts on mangroves in Vietnam’s Xuan Thuy National Park. There were many highlights on the trip, which included meeting lots of new friends, trying new and interesting local foods, and seeing mudskippers for the first time!

Jan Bikker: Jan spent her summer in the ABEL lab at McMaster as part of a collaborative study investigating the effects of microplastic exposure on fish behaviour. When not in the lab, she also got to help with fieldwork for two projects- one monitoring the population of the invasive round goby in Hamilton Harbour and the other looking at changes in the fish and zooplankton communities on a gradient away from wastewater treatment plants.

Lisa Erdle: Lisa spent time on Georgian Bay to investigate the effectiveness of washing machines filters at capturing microfibers. Nearly 100 volunteers in Parry Sound installed washing machine filters in their homes as part of a pilot program with U of T and Georgian Bay Forever.

Arielle Earn and Ludovic Hermabessiere: Arielle and Ludovic spent a day in the Rouge Valley during the 2019 Eco Exploration Event talking to many new people about microplastics. They were able to explore some of the beautiful conservation land and even spent time doing a small cleanup of the area, finding a straw, a coffee cup and many fragments of plastic surrounding the nearby stream. They also got to hear many stories from the people they talked to – including one about the folklore surrounding Bigfoot’s existence in Rouge Valley!

Alice (Xia) Zhu: Alice spent her summer analyzing data on microplastics from San Francisco Bay. Many different shapes and polymer types of microplastics were found in sediment, fish, surface water, stormwater, and wastewater from San Francisco Bay and Alice analyzed patterns in their characteristics to help determine the sources of microplastics to The Bay. She had a great time learning new ecological statistics and R functions. Fun fact: over 300 samples were analyzed in total, including 152 fish!

Ludovic Hermabessiere: Ludovic recently moved here from France and spent his first few months in Canada working at the Rochman lab with Raman spectroscopy. His work will help to analyze and identify potential plastic particles faster. Ludovic is also preparing the arrival of a new equipment to identify smaller plastic particles.

Kennedy Bucci and Hayley McIlwraith: This summer, Kennedy and Hayley left the traditional lab for a natural laboratory at the Experimental Lakes Area in Northwestern Ontario. They collected surface water, sediment, and air samples to look for microplastics in remote boreal lakes. They enjoyed life at the field station, canoeing and portaging to their sampling sites, and returning to camp in the evening for swimming, bonfires, and delicious meals prepared by the camp chefs.

Bonnie Hamilton: Bonnie spent a portion of her summer in the Canadian High Arctic to evaluate contaminant concentrations in Arctic char—a cold adapted Salmonid. This year, her trip was spent off-grid on the tundra at the mouth of the Lachlan River 150km west of Cambridge Bay. Some of the trip highlights included working with collaborators at DFO, UBC and the Arctic Research Foundation, Arctic wolf and grizzly sightings and sampling these beautiful fish!

Annissa Ho and Lara Werbowksi: Lara and Annissa got out of the lab and spent a day at the Outer Harbour Marina counting and categorizing trash collected by Seabins. Despite the smell, the activity attracted some passers-by and allowed Lara and Annissa to share their new knowledge of the trash in the marina! Overall, it was a great experience and the results were fascinating. Their favourite finding? One bin captured more than 1000 pieces of plastic in less than 24 hours!

We can’t wait to see what our Trash Team gets up to this fall and winter season, likely it will be filled with more tales of field work, outreach events, and travels to see plastic pollution abroad.
