Are tea bags compostable?

Some tea bags contain plastic and are not meant to be composted ... or drank. 

I built my first compost pile around 1986. Give or take a year. Over the years (decades — yikes!), I consider myself on intimate terms with dozens of materials, from toilet paper rolls to pineapple rinds (not recommended for the compost pile. Corncobs, either).

One thing I learned early on was that tea bag “strings” not only survive 160-degree compost piles, but also, once transferred to the garden, they continue to survive as a pain in the you-know-what, wrapping around trowels and hand scratchers.

Turns out, I’m not the only one who dislikes tea bags ...

In 2013, the municipality of Skagway conducted a study of the community’s waste (trash) profile. The results were quite telling and the townsfolk realized that something needed to be done: In a nutshell, about one-third of the trash collected was recyclable, one-third was garbage and one-third was compostable.

Looking at the numbers, plans got underway to develop a composting system to eliminate some of the excess waste from the incinerator system.

After multiple delays and budget overruns, the project was finally open to the public in April, albeit in a soft-opening phase ...

Here’s how it works:

The composter (let’s call it Big Bertha) is about the size of the payload of a semi-truck. Skagwegians can offload their compostables into a front loader, which in turn dumps its payload into the first chamber of the system. And so it begins ...

This state-of-the-art composting system was designed to handle the massive influx of food waste during Skagway’s busy cruise ship season. But without one of those on the calendar for the immediate future, it’s operating on a smaller scale.

Maybe that’s a good thing, so they can get the kinks out.

One of the perks of Big Bertha is her ability to break down things such as small animal bones and meat that wouldn’t normally break down in a home compost pile.

Skagway’s Solid Waste Committee Chairperson Annemarie Hasskamp says coffee grounds and paper filters are okay, but tea bags are not.

“Teabags. That’s kind of a tricky one,” she says.

You see, tea LEAVES are totally compostable.

But some tea bags have thermoplastic fibers in them.

Who knew?

If you’re like most people (myself included), we’ve been composting tea bags for quite some time.

It seemed to make sense that these seemingly paper-type bags would decompose, releasing the natural plant residue (tea) back into the ground.

So why do some tea bags contain plastic?

Several tea bag manufacturers use polypropylene, a sealing plastic, to keep their paper tea bags from falling apart.

And tea bags sealed with plastic glue (or made of plastic altogether) don’t belong in a compost pile.

Okay readers, I hear rumblings in the audience. What’s the big deal with a little bit of plastic, Marion?

Well, recent research from McGill University in Canada found that some types of tea bags actually leak millions of plastic particles into our tea cups, not only from the sealing plastic but also from the bag itself.

So how do you know if your favorite tea brand is plastic-free?

Here is a short list of a few popular worldwide brands and whether they contain plastic:

Tazo and Teavana (Starbucks): YES

Bigelow Tea Company: NO

Yogi Tea: YES

Celestial Seasonings: NO

Stash Tea: NO

Lipton: YES

Tetley: YES

PG Tips: NO

For the past couple years, I researched and compiled an amazing list of compostable materials called “220 Things You Can Compost.”

Now it looks like I need to revise it!

 

Kodiak garden tasks:

Be kind to your plants: Harden then off and transplant on overcast, not sunny, days.

Pull weeds. Be gentle when raking the lawn.

Last call for dividing rhubarb!

Sow beets, spinach, turnips, peas, bush beans, carrots. 

Sow succession crops of cilantro, lettuce, Chinese cabbage, Bok choy, broccoli.
