Coffee grounds are a great source of organic materials for your compost pile. They’re an excellent source of nitrogen, and it’s a smart way to reuse something that would otherwise end up in a landfill.
However, you also need to consider whether you can add used coffee filters to your compost pile. Chemex filters are one type of coffee filter that can be composted.
What Makes Chemex Filters a Compostable, Green Option?
Chemex is a brand that specializes in high-quality pour-over coffee makers. You can also find Chemex filters and other accessories for these coffeemakers. Here’s why these outstanding filters are some of the best coffee filters for the environment.
Compostable and Biodegradable
All the filters offered by Chemex are compostable and biodegradable. These filters will break down once you add them to your compost pile and won’t release any harmful chemicals like bleached filters sometimes can.
Chemex makes its filters in the US and uses materials that come from the US. The brand has excellent visibility over its supply chain and can guarantee the quality of the materials used from one batch of filters to the next.
Chemex filters use materials that come from suppliers who comply with different sustainability programs, including the Sustainable Forestry Initiative, the Forest Stewardship Council, and the Programme for the Endorsement of Forest Certification.
These different programs encourage wood suppliers to take steps to prevent deforestation, protect indigenous populations, and adopt transparent sourcing practices.
If you’re looking for compostable filters because you want to do your part to protect your environment, you can rest assured that Chemex shares these values. You might also be interested in our Chemex vs coffee maker guide.
Is There a Difference Between White and Natural Filters?
Chemex offers a selection of white and brown coffee filters. White coffee filters go through a bleaching process. While some brands use chlorine to bleach their filters, Chemex uses a different method that relies on oxygen bleaching.
Oxygen bleach is a safer way of whitening paper products. It doesn’t introduce any toxic chemicals and won’t affect the taste of your coffee.
You can also find brown or natural filters from Chemex. These filters might be better for the environment since you’re using paper products with less processing, which results in a shorter manufacturing process that uses fewer resources.
There are no significant differences in taste between white and brown coffee filters, but some coffee lovers have a preference for one or the other. Both options are valid if you’re looking for compostable filters, but brown filters might be a little better for the environment due to their simpler manufacturing process.
Other Reasons to Use Compostable Chemex Filters
These filters are thicker than what other brands offer. Chemex claims that its filters are 20 to 30% thicker.
A thicker filter means that you’re getting better filtration. Unlike unfiltered coffee, your beverage will have fewer bitter compounds in it. These thick filters also do a better job of removing impurities that can affect the taste of your coffee.
Besides, using a thick filter makes it easier to remove used coffee grounds from your coffeemaker and transport them to your compost pile without making a mess.
You should also consider using Chemex filters if you have a coffee maker from this brand because you’ll get filters with a shape and size that fit your coffeemaker perfectly. It ensures that you’re filtering your coffee evenly and get a great-tasting cup of pour-over coffee every time.
