Compostable PLA Straws are a sustainable alternative to plastic straws
The best way to dispose of these straws is through commercial composting facilities. Unlike most single-use plastics, which break down quickly in a landfill, biodegradable plastics take a very long time to decompose. Eventually, they turn into biomass, which releases carbon dioxide and methane, two powerful greenhouse gases.
In addition, the process is not as simple as it sounds. To be properly composted, these straws require special treatment at each step of the process. First, they need to be placed in specialized industrial composting bins. Then, they need to be heated to 140 degrees Fahrenheit for more than a week. It is not recommended that they be buried in a home compost pile, as this may contaminate the soil.
Once they are broken down, the methane released during the process is 23 times more harmful to the environment than CO2. When combined with other plastics, the result is a waste that is not only harmful to humans and wildlife, but pollutes the countryside and coastline.
There are some other biodegradable alternatives that are better for the environment, such as bamboo. Nonetheless, these products are not as easy to recycle as paper or plastic. Paper is not as environmentally friendly as biodegradable plastics, which require the use of clean energy to break down.
One of the biggest challenges with using PLA straws is that they aren't always recyclable. Many PLA straws can't be recycled in your curbside recycling bin. But if you choose to reuse them, the process will be more complicated.
