Environmental impact and use of compostable produce bags

Since 2017, French regulations have prohibited single-use plastic bags in the fruit and vegetable aisles, replacing them with compostable alternatives made of at least 60% plant-based material. However, experts note that the environmental benefits of these bags depend heavily on repeated reuse and proper disposal.

ADEME warns that bags labeled ‘biodegradable’ can still act as harmful plastic waste if they end up in nature or are incinerated. Furthermore, the choice of packaging can impact food preservation. While thin bags allow leafy greens and herbs to breathe, compostable models can create a warm, humid microclimate that may accelerate spoilage. Additionally, certain fruits like apples and tomatoes release ethylene gas, which can speed up the ripening and aging process of surrounding produce.
