There is a lot of confusion between the biodegradable and
compostable plastic bags because of their similar usage. Whatever their similarities -- they can be easily broken down and returned to the natural environment -- biodegradable bags are also very different from
compostable plastic bags.
Biodegradable and compostable plastic bags
Basically, many of the
compostable plastic bags found today are broken down in commercial composting facilities. That means landfills are definitely not an alternative. Specialized facilities provide a specific atmosphere of temperature, humidity, air and other environmental factors to facilitate the decomposition process.
Biodegradable bags, on the other hand, are designed to be broken down by natural organisms such as bacteria and fungi. These bags may not continue to take up space in landfills the way regular plastic bags do.
However, not all biodegradable plastics decompose in landfills. So when buying biodegradable products, look for specific labels that indicate the product's ability to decompose in landfills. Considering that most of the plastic we throw away ends up in landfills, we should be using landfill compostable plastic bags. These products are made by combining traditional plastics with organic additives that attract microbes.
Use compostable plastic bags
At this point, it's clear why so many companies are turning to
compostable plastic bags. The danger of climate change has emerged as one of the main causes of concern today. To make a significant difference, consumers and manufacturers need to join forces. At present, many companies are ready to sell the most stylish and environmentally friendly biodegradable packaging or shopping bags. Sustainability has never been more fashionable. Moreover, consumers are a key part of the process. The main reason people tend to choose traditional materials is the price. Making a suitable biodegradable plastic bag is a more expensive process and therefore a higher procurement price. This is where the persuasive power of the company and our individual desire for change come into the equation.
Criteria for selecting compostable plastic bags
There are plenty of options on the market when it comes to compostable plastic bags. If you are not an expert in this market and you are considering buying biodegradable garbage bags, you should consider the following criteria in your selection process.
Durability: You should test the strength of a bag compared to the traditional bags you buy. Biodegradable bags tend to be more fragile due to their composition. So don't forget to pay attention to whether they tear or leak easily, and try to avoid overfilling.
Certification: Appropriate biodegradable plastic bags should be certified by composting and biodegradation standards.
Decomposition rate: Of course, one of the main criteria is how long it takes the bag to decompose. Most brands will state this on the package.
Even though there's certainly a lot to take care of, don't forget to incorporate
compostable plastic bags into your daily activities, they have real benefits for the environment. Switching to
compostable plastic bags is a relatively simple conversion that minimizes the need for plastic bags. Hyde specializes in biodegradable and compostable products and actively promotes green living.
