The Scoop: Composting vs. Biodegrading

There are SO many buzzwords flying around the sustainability community, and two that get thrown around nearly interchangeably are “compostable” and “biodegrade”. Even though these terms may be used in similar contexts, they actually mean significantly different things. It’s important to know the difference so you don’t end up engaging in greenwashing practices.

What is composting?

According to the EPA, composting is “a controlled, aerobic (oxygen-required) process that converts organic materials into a nutrient-rich soil amendment or mulch through natural decomposition.” Basically, it’s a fancy way to say that natural materials (like food scraps, wood, or even fibers like wool) can be broken down using a variety of processes into a rich soil that can be added to your garden or make your indoor plants really happy. Some common composting practices include backyard composting (using a composting tumbler or a compost pile), commercial composting (in which compost is broken down in large facilities like A1 Composting in Colorado), or even vermicomposting (breaking down food in a bin using worms!). Compostable items are designed to break down using these processes, and many products with compostable packaging identify whether they can be backyard composted or need to be composted commercially.

What does it mean to biodegrade?

Biodegrading is often associated with composting; however, there are some significant differences. According to Merriam-Webster Dictionary, biodegradable means “capable of being broken down especially into innocuous products by the action of living things (such as microorganisms)”. Biodegradable products are designed to break down by microorganisms under proper conditions, which makes them nearly as environmentally-friendly as compostable items. Here’s the catch: Biodegradable items are not designed to go through the same composting processes (meaning they’re not truly compostable), but rather are meant to break down naturally through normal trash disposal. And when your trash ends up in landfills, these landfills are not designed or maintained in a way that promotes biodegradable products breaking down. The gasses, toxic liquids, and sheer pressure of these layers of landfill are not conducive to the breaking down of biodegradable items, which needs air to complete the process. Therefore, if biodegradable items end their journeys in landfill, they won’t, in fact, biodegrade. They’ll simply add to landfill volume.

So which is better, and where do we go next?

At Summit Sustainable Goods, the answer for us is clear: composting is king. Composting results in nutrient-dense and rich material which can be used to strengthen our soils, while biodegrading, despite the best intentions, can often add to landfill rather than reducing it. That’s why we at Summit prioritize compostable packaging and products over items labeled as “biodegradable”, because we recognize that the term “biodegradable” can be sustainably misleading?
