Bag will disintegrate in just a few days- mostly due to moist waste- but of course, this is expected. Not recyclable, which is also understandable since they are compostable.

An Overview On Biodegradable Trash Bags

Before buying these trash bags, it helps to understand the difference between biodegradable and compostable ones. Biodegradable means that the materials will eventually be disintegrated by natural biological processes.

Plastic bags do not biodegrade. But biodegradable products break down relatively quickly once they arrive at landfills. Some products are made to complete this process faster, ideally within a few months to a few years.

Composting is when organic waste is recycled and reused later. You may have heard of composting organic materials like food and turning it into fertilizer, or even done it yourself in your back yard. Compostable garbage bags, however, have to be sent to proper composting facilities. Not all of them will break down naturally in landfills.

Your garden will thank you if you start composting. Not only does it fight plant diseases, insects and pests, it enriches the soil by retaining moisture and adding nutrients. As an added plus, you’ll have less trash to take out!

The Biodegradable Trash Bag Buying Guide

  • When comparing biodegradable and compostable garbage bags, decide which type will be better for you. Some are hybrids that claim to serve both purposes, but read reviews before purchasing.
  • Some brands’ bags may break more easily and not have as much stretch. See what their weight capacities are, and compare thicknesses of different bags before your order.
  • Biodegradable and compostable garbage bags may need to stored differently than regular ones. Some specify that they must be kept out of excessive heat or be stored in a cool, dry place.
  • These bags do not have infinite shelf lives. Read the directions, as some must be used within a certain amount of time, like one year.
