Your sourdough arrives in a fully home compostable bag, made from a single-layer compostable film that’s waterproof enough to protect the loaf and maintain freshness on the doorstep. But here’s the part we love: they break down in around 12 months without leaving microplastics or pollutants behind. That’s compared to a standard plastic bag, which can take up to 450 years to degrade.When you’ve finished the loaf, you can pop the bag in your food waste bin, add it to a garden compost heap, or use it as an organic waste liner. It’s genuinely useful right to the end.
