How Do Compostable Bags Work?
Using compostable bags is a great way to reduce waste. However, there are some key things to consider before making a decision. This article will examine the benefits and drawbacks of different types of compostable bags. It will also discuss the certifications and tests used to make sure they are safe.

Bioplastics
Despite the hype, bioplastics are not all eco-friendly. They can leave toxic residues and are not always degradable in the environment. It's important to understand how these plastics break down so that you can make an informed decision.
The most durable plastics are those that have a crystal-like molecular structure. This allows them to withstand the forces of water. If you are concerned about food safety, you may want to look into more durable plastics.
The production of bioplastics generates fewer greenhouse gas emissions than traditional plastics. This is because the plants used to produce them absorb carbon dioxide from the air while they're growing. These plants then release the same amount of carbon dioxide when they're broken down.
In addition to greenhouse gas emissions, bioplastics should also be considered for their impact on land and water use. They may leave toxic residues that can contaminate the composting process.

Cornstarch
Increasingly, companies are using cornstarch to make environmentally friendly packaging materials. Corn starch is an affordable, renewable resource that is easy to produce and recycle.
Cornstarch plastic is an environmentally friendly alternative to traditional fossil fuel plastic. It can be used for food packaging, textiles and medical devices. It is a sustainable material that uses 65% less energy than conventional petroleum-based plastic.
It is also biodegradable. When composted, it decomposes into carbon dioxide and water within 90 days. This reduces greenhouse gas emissions by 68%. Its use has been proven to be an effective solution to the global plastic crisis.
It is important to choose products that are recyclable and will not be thrown away after a single use. This will reduce the amount of toxic waste and pollution that ends up in landfills.
Tests
During an ongoing research project, BSIbio and University of British Columbia (UBC) participants loaded thirteen different compostable products into polypropylene mesh bags. They then tested each product by following ASTM D6400 standards.
The test's purpose was to determine the potential for disintegration of the product and to find out how it performed in an environmentally friendly setting. Various factors contributed to the results, including the depth of burial, the temperature and moisture levels in the soil, and the aeration of the material.
The results indicated that the Mater-Bi EF05B shopping bag had good biodegradability, releasing little toxic substances and no persistent microparticles. It also showed a substantial conversion into CO2 in a short period of time.
The same bag was also tested with monocotyledonous plants, barley and cress. The germination of the cress seeds was not negatively affected by the leachate.
Measurements
Getting a bag made from plants is a green and stylish proposition, but if you are not lucky enough to live in the vicinity of a compost bin, you will be stuck with the dreaded styrofoam container. Fortunately, there are many alternatives to the paper sack, including the compostable variety. You can find these Compost Bag at your local hardware store, supermarket, or even pharmacies. They are also available in a number of cleverly shaped shapes.
One of the most gratifying aspects of being an eco-conscious consumer is the sheer number of products on hand to choose from. In fact, you are more likely to find a selection of branded products that are designed and crafted to suit your needs, as opposed to a generic one-size-fits-all approach.
Certifications
Getting certified is a great way to promote your compostable plastic bags. The certification process involves a number of steps, including accredited laboratory testing. The results are sent to a third party certifier, who then decides if the product meets the relevant standards.
The most well known certifier is the Biodegradable Products Institute (BPI). The organization is based in the USA, and works in the biodegradable/compostable space. They provide education and advocacy, and are the largest third-party certifier in the US.
Another common certification is the International Organization for Standardization's ISO 9000 series. The certification ensures that your product meets the highest standard of testing.
A relatively new certification is the Compost Manufacturing Alliance. This newer standard requires products to be tested in a real compost facility.
