In today’s world, with plastic pollution causing problems, we’re all looking for better alternatives. Compostable bags seem like a greener choice, especially for food waste. But are they really as good for the environment as they seem? Let’s find out.
What are Compostable Bags?
Compostable bags are made partly from plants. The two main ingredients are PBAT (a special kind of compostable material) and something renewable (like cornstarch or PLA). PLA, made from cornstarch or other plant sources like beets or sugarcane, is better than cornstarch alone because it’s stronger and doesn’t get soggy as easily.
This means there’s no such thing as a 100% plant-based compostable bag. A bag made only from cornstarch or PLA would leak and fall apart easily with moisture and weight.
But there’s a catch with the word “compostable.” These bags only break down effectively in special circumstances provided by industrial composting facilities. These facilities are controlled to have the right temperature, moisture, and tiny helpers (microbes) to make the bags decompose. This is important because compostable bags likely won’t break down well in your home compost or in a landfill.
It’s also good to know the difference between compostable and biodegradable bags. All compostable bags are biodegradable, but not all biodegradable bags are compostable. Biodegradable bags will leave behind tiny pieces of plastic or other stuff that can harm the environment when they break down. Compostable bags, on the other hand, are designed to break down completely into natural things, leaving no harmful traces behind when composted.
The Good and the Bad of Compostable Bags for Food Waste
Compostable bags have both good and bad points, especially when used for food waste. Let’s look at both sides.
The Good
- Less food waste in landfills, less methane gas: Food waste in landfills creates methane, a gas that’s about 20x worse for the environment than carbon dioxide. Compostable bags help keep food scraps out of landfills, so there’s less methane and less climate change.
- Makes good compost for your soil: When composted correctly, food waste and compostable bags turn into nutrient-rich compost. You can use this compost to make your soil better, helping it hold water and grow healthier plants. This is good for farming and means we need less chemical fertilizers.
- Uses less oil than regular plastic bags: Compostable bags are made from renewable plant materials, which is better than regular plastic bags made from oil. Making them uses less energy and creates fewer greenhouse gases.
The Bad
- Can mess up recycling if thrown in the wrong bin: Compostable bags can cause problems if they end up in recycling bins. It’s really important to put compostable bags in the right place, like a special composting facility or collection program.
- Might not break down well in your home compost or in a landfill: Compostable bags need the special conditions of an industrial composting facility to break down properly. In your home compost or a landfill, they might take much longer to decompose or not decompose at all. This can give people a false sense of being eco-friendly and add to the waste problem.
Compostable Bags vs. Other Ways to Deal with Food Waste
Compostable bags are a handy way to collect food waste, but it’s worth looking at other options too.
- Composting in your backyard: This is a great way to handle food scraps and other organic things at home. It reduces waste, makes great compost for your garden, and is good for the environment. But it might not work for all food waste, like meat and dairy, which can attract pests and smell bad.
- City composting programs: Many cities have programs that pick up food scraps and other organic materials (like leaves and grass) from your home. These programs are an easy way to keep food waste out of landfills and help the environment. But they might not be available everywhere, and the rules can be different depending on where you live.
How to Dispose of Compostable Bags the Right Way
Disposing of compostable bags correctly is key to making sure they’re actually good for the environment. Here are some tips:
- Look for certified compostable bags: Make sure the bags you buy are certified compostable by trusted groups, like the Biodegradable Products Institute (BPI) and Compost Manufacturing Alliance (CMA). These certifications mean the bags meet certain standards for compostability.
- Find places that take compostable bags: Look for industrial composting facilities or collection programs near you that accept compostable bags. Many cities have curbside pickup for organic waste, including compostable bags.
- Keep them clean: Don’t put non-compostable things in your compostable bags, like plastic stickers or twist ties. These things can mess up the composting process and make the compost less useful.
- Follow the rules: If your city has a composting program, follow their guidelines carefully. They might have rules about what kinds of food waste and compostable bags they accept.
Composting: A Big Change
Before we had lots of composting facilities and easy-to-use compostable bags, dealing with food waste wasn’t as good for the environment. People often threw food scraps in the regular trash, which ended up in landfills. This was a big problem.
Food waste in landfills creates methane, a gas that’s much worse for global warming than carbon dioxide. This added to climate change and made landfills fill up faster.
Also, without easy ways to compost, the good stuff in food scraps was wasted. Instead of helping the soil and farms, these nutrients were buried and lost.
Today, things are much better. We have more industrial composting facilities and compostable bags, making it easier to keep food waste out of landfills. This has helped reduce methane gas, which is important for fighting climate change.
Plus, the compost made from food waste is now a valuable resource for farmers and gardeners. It makes the soil healthier and reduces the need for chemical fertilizers.
But we still have work to do. Even though there are more places to compost, it’s not available everywhere. Many communities, especially in rural areas, still don’t have easy ways to compost. And if people put compostable bags in the wrong place, like with regular trash or in their home compost pile, it defeats the purpose.
A Compostable Future
Imagine a world where all food waste is collected in compostable bags and composted properly. New technology could make this happen. Imagine compostable bags that break down even in home compost piles, so everyone can compost their own food waste easily. Picture small composting machines that make composting possible even in small towns or rural areas.
This would be amazing for the environment. We’d see much less waste in landfills and less methane gas. Compost would be everywhere, making the soil healthier and leading to better farming with fewer chemicals. We’d be closer to a circular economy, where we reuse and recycle everything.
This would make a real difference in the world. We’d have cleaner air and water, healthier nature, and stronger communities. Landfills wouldn’t fill up as fast, and we’d create fewer greenhouse gases. This is a big step towards a better future for everyone.
