Compostable produce bags are made from 100% plant-based materials. These can be composted or thrown in the garbage at the same rate as other food waste. The bags can also be composted at home or in the garden. They are compostable because they contain no animal by-products, such as manure, and they are biodegradable, meaning they decompose at a rate similar to that of natural soil.

How are biodegradable bags made?
The bags are made from plant-based materials. In order to break down the plastic, the temperature needs to be 50 degrees Celsius. Secondly, it needs to be exposed to air for at least 24 hours before it can be used again. Thirdly, the bags must be stored in a cool, dry place. The bags can also be composted if they are left in the compost pile for a period of time.
Is compostable plastic actually compostable?
Compostable plastic is not harmful to the environment. That doesn’t mean it’s okay to put it in your backyard compost bin. Compostable plastic needs specific composting conditions to break down, not in a landfill. So, if you want to compost your plastic, you’ll need to make sure you have the right conditions for it to break down.
Are compost bags made of plastic?
Compostable plastics are manufactured from plant-based materials, but look and feel like conventional plastics produced from petrochemicals. They’re made from polyethylene, polypropylene, and polyurethane, which are commonly used in the construction industry.
Non-comprehensible materials are processed in a way that breaks down the plastic into its constituent parts such as water (Complete list below)
- Carbon dioxide
- Hydrogen
- Oxygen
- Nitrogen
- Sulfur
- Phosphorus
- Silicon
- Iron
- Manganese
- Copper
- Zinc
- Nickel
- Cobalt
- Boron
- Chromium
- Molybdenum
- Tin
- Lead
- Mercury
- Arsenic
- Among others
- Cadmium
- Mercury compounds
These materials can then be recycled or composted, depending on how they’re processed and how much of them are needed to make a given amount of plastic.
The process of composting and recycling plastic is called bioremediation, or “bioprocessing,” and is one of the most environmentally friendly ways to dispose of plastics. It’s also the fastest and most cost-effective way to reduce plastic waste.
Why are compostable bags so expensive?
Compostable plastic bags are more expensive than traditional plastic due to the cost of raw materials being more expensive, less readily available, and manufacturing processes costing more.
How long do compostable bags take to decompose?
Under certain conditions the bags can break down within 10-45 days. Composted bags do not leave a trail on the surface of the soil. This means that you can use them as a mulch on your lawn or garden.
