PLA (polylactic acid):

• PLA is a biodegradable polymer of plant origin, derived from renewable sources such as sugar cane, corn or other starch-rich plants.
• It is often used as an environmentally friendly alternative to traditional petroleum-based plastics.
• PLA is compostable under appropriate industrial conditions, meaning it can decompose naturally in special composting facilities.

Kraft:

• Kraft paper is a type of strong paper made from chemically unbleached wood pulp, usually obtained from pine or spruce.
• It is known for its robustness and resistance, making it suitable for various packaging applications.
• Kraft paper is often used for making bags, boxes and other food packaging because of its durability and natural appearance.

The combination of these materials gives the bag the necessary strength (kraft paper) and the necessary barriers (PLA) for proper coffee preservation. Coffee is a delicate product, and direct contact with ambient air degrades its aromatic properties.

The label is not compostable.

"Compostable, but not really," that's our way
to tell you both: "We don't have all the answers" and "We are doing our best, within the limits of our area of ​​control."

Our bag is made of kraft paper, polylactic acid (PLA) and rice paper. All are biodegradable materials, meaning they completely degrade under the action of microorganisms (bacteria and fungi).

Now, determining whether a biodegradable product is also compostable is more complicated…

A brief overview of so-called compostable packaging:

• The degradation process of compostable packaging varies depending on the type of material, the size, and especially the number and diversity of the different barriers it contains. Our precious grains require several different layers for optimal preservation (see question above). Unfortunately, these essential barriers lengthen the degradation process.
• The brown bin wasn't introduced for collecting packaging, but food scraps. Composting food scraps is very different from managing packaging. The former can compost in about twenty days, while the latter can take months. Furthermore, you don't get quality compost from a pile of containers. That's why many industrial composting facilities remove so-called compostable packaging from their operations.
• In short, technically the bag is indeed compostable. But in reality, it might not be composted, depending on the facility where it ends up. Believe us, we're the first to be frustrated by this!

So what should you do with your "compostable, but not really" bag? See the next question.

The short answer: trash.

The answer (a little more detailed):

• If possible, reuse it as much as possible! Go to one of our bulk sales points (see the list in the 5th question).
• Use it as a trash bag instead of purchasing specific bags, thereby reducing the production of materials intended only to be thrown away. At home, we all have bags that, unfortunately, cannot be placed with confidence in the recycling or compost bin: chip bags, delivery bags, frozen vegetables... and coffee bags.
• If you have household compost, you can put the bag in it! Be sure to remove the label though. We would like to have your feedback on the duration of degradation in your domestic compost.
• If none of these options suit you, unfortunately the most reasonable solution is to throw the bag in the trash. Indeed, when industrial composting facilities remove products that they cannot process for disposal, these products take with them 10 to 15% of truly compostable materials. So, it is better not to contribute to the problem and directly throw uncertain material in the trash :/

On the one hand, this is explained by the absence of a truly recyclable option.

For packaging to be recycled, two conditions must be met:

1. It must be correctly sorted according to its material.
2. This material must find a buyer.

However, in the case of a coffee bag, as mentioned previously, to ensure optimal preservation of the product, it is necessary to use an assembly of layers of different materials. This complicates, if not makes it impossible, sorting materials!

You may have noticed semi-rigid plastic “pouch” type bags on the shelves of your roasters, made of a single material. Unfortunately, there are very few buyers for this type of plastic, which most of the time ends up in landfills at best, and at worst exported abroad in "mixed" bales including the future is more than uncertain...

Since no current option guarantees an ecological end of life, our decision is to consciously choose our impact, rather than looking for "the best bag".

By opting for the compostable version, we have simply chosen not to introduce more plastic into the environment.
