Oil spills can cause serious damage to our oceans and the creatures that live there. Sometimes, these spills release millions of barrels of oil into the water. But how do we clean up such a huge mess?
On April 20, 2010, an oil rig in the Gulf of Mexico exploded, causing a massive oil spill. Thousands of barrels of oil leaked into the ocean every day. It took 87 days to stop the leak, but even five years later, about 16% of the oil was still on the ocean floor. Scientists are still studying how this spill affected the environment and local communities.
The first step in cleaning up an oil spill is to contain it. Oil doesn’t mix with water; instead, it floats on the surface. To keep it from spreading, we use floating barriers called booms. These booms look like a series of floating cushions and have a skirt that hangs below the surface to catch oil underneath.
Once the oil is contained, we can remove it with skimmers, which are like tools used to clean swimming pools. If skimmers don’t work well, we might use dispersants. Dispersants are chemicals that help break up the oil, making it easier to manage. However, some dispersants can harm coral reefs, so they aren’t always the best choice.
Scientists are always looking for better ways to clean up oil spills. Some researchers have created a special sponge made from modified wood called Nanofibrillated Cellulose. This sponge can soak up oil without absorbing water.
Another team at Ohio State University developed a sponge inspired by nature. It uses a stainless steel mesh coated with silica, which makes it bumpy. This sponge repels water but sticks to oil, making it a promising tool for oil cleanup.
When oil reaches the shore, nature can sometimes help clean it up. We can use biological agents like enzymes or microorganisms to speed up the process. This might involve adding bacteria to the spill site, a method called “bioaugmentation,” or providing nutrients to help existing bacteria grow, known as “biostimulation.”
Oil spills are tough to handle, but scientists are always working on new and better ways to clean them up. One idea is to create more environmentally friendly vehicles. For example, the Toyota Mirai uses hydrogen fuel and produces no emissions, which could help reduce the risk of future oil spills.
If you’re curious about how we get oil from the ground, you can watch a video by Trace that explains where our oil comes from.
Gather materials like water, vegetable oil, a shallow dish, and items like cotton balls, spoons, and paper towels. Create a mini oil spill in the dish and try different methods to clean it up. Experiment with using the cotton balls and spoons to remove the oil. Discuss which methods were most effective and why.
Using materials such as straws, string, and plastic wrap, design and build a model oil boom. Test your boom in a container of water with a small amount of oil. See how well it contains the oil and think about improvements you could make. Share your design with the class and explain your choices.
Choose one of the innovative cleanup tools mentioned in the article, such as the Nanofibrillated Cellulose sponge or the silica-coated sponge. Research more about how it works and its effectiveness. Create a short presentation to share your findings with the class, including visuals or diagrams if possible.
Investigate how microorganisms are used in cleaning up oil spills. Create a poster or infographic that explains the processes of bioaugmentation and biostimulation. Include examples of specific bacteria used and how they help break down oil. Present your work to the class and discuss the benefits and challenges of using microorganisms.
Divide into two groups and prepare for a debate on the topic: “Are alternative energy sources the best solution to prevent future oil spills?” One group will argue in favor of alternative energy sources like hydrogen fuel, while the other will discuss improvements in oil extraction and transportation. Present your arguments and engage in a respectful debate, considering environmental, economic, and technological perspectives.

Oil spills can have devastating effects, with some releasing millions of barrels of oil into the ocean. How do we clean up such a significant mess?
On April 20, 2010, an oil rig in the Gulf of Mexico exploded, releasing thousands of barrels of oil into the coastal waters each day. The leak was finally capped 87 days later, but five years later, an estimated 16% or more of the oil still remains on the ocean floor. Scientists continue to assess the damage to ecosystems and local communities.
So, how are spills like this cleaned up? The first step is to contain the spill. Oil is insoluble, meaning it doesn’t mix with water; instead, it floats on the surface. Temporary floating barriers, known as booms, are used to corral the oil. These barriers look like a series of floating cushions and have a skirt that extends below the surface to catch any oil underneath.
Once the oil is contained, it can be removed using skimmers, similar to tools used to clean pools. If skimmers are not effective, dispersants—chemical emulsifiers—can be sprayed. Some dispersants contain surfactants, which help break up the oil by reducing the surface tension that prevents water and oil from mixing. This can help prevent the oil from reaching shorelines and damaging sensitive ecosystems. However, some research indicates that dispersants may be harmful to coral, suggesting they may not be suitable for every situation.
Other tools include absorbents like clay and straw, which can soak up some of the oil but also absorb a significant amount of water, making them less than ideal. Fortunately, researchers are developing innovative solutions. For example, scientists from a Swiss materials research institute have created a sponge made from chemically modified wood, known as Nanofibrillated Cellulose, which can absorb oil while leaving water behind.
Additionally, researchers at Ohio State University have developed a nature-inspired sponge. This technology features a stainless steel mesh coated with silica, creating a bumpy exterior. This layer is treated with surfactants and sealed with a polymer coating that repels water, allowing it to bind to oil. While these technologies show promise, they are still in the early stages of development.
For oil that washes ashore, nature can sometimes help, often with a little assistance. Biological agents like enzymes or microorganisms can be introduced to speed up the biodegradation process. According to the EPA, this can involve “bioaugmentation,” where bacteria are added to the spill site, or “biostimulation,” where nutrients are provided to enhance the growth of existing oil-degrading bacteria.
While oil spills can be challenging, scientists are continually seeking new and improved methods for cleanup. Another potential solution lies in the development of more environmentally friendly vehicles. For instance, the new Toyota Mirai is designed with sustainability in mind, using hydrogen fuel and producing zero emissions.
