What is a biodegradable plastic bag?
When it comes to plastics, we all know that they’re bad for the environment. They take up space in landfills and pollute our waterways, to name a few problems. What you may not know is that many types of plastic are actually biodegradable. In this blog post, we will explore what a biodegradable plastic bag is and how you can use them to reduce your environmental impact. By understanding the benefits of these bags, you can make an informed decision about whether or not they’re right for your business.

What is a biodegradable plastic bag?
A biodegradable plastic bag is a type of bag that is made from materials that can break down in the environment. This means that the bag will eventually disappear and be Converted into something else in nature. Some common types of biodegradable plastics include polylactic acid (PLA), polyhydroxyalkanoates (PHAs), and polyglycolic acid (PGA). The polylactic bags are often preferred over traditional plastic bags because they are environmentally friendly and do not contribute to environmental pollution.

Types of biodegradable plastic bags
There are a few different types of biodegradable plastic bags: compostable, recycleable, and renewable.
Compostable bags are made from plant-based materials that can be broken down by the environment into soil or fertiliser. The compostable bags decompose in a year or less, and can be used again to collect food scraps or garden waste.
recyclable bags are made from paper or other materials that can easily be shredded and turned into new products. These bags can last for up to 10 years before they need to be replaced, but will eventually break down into small pieces that can be recycled.
renewable plastic bags are made from materials like corn or sugar cane starch that can be turned into new plastic bags when they wear out. These bags have a lifespan of around 20 years, but may need to be replaced every 5-10 years due to degradation caused by sunlight and rain.
How do biodegradable plastic bags work?
Biodegradable plastic bags work by breaking down into small, harmless pieces over time. The bag decomposes into a series of chemical compounds, including carbon dioxide and water, which are released back into the environment. This process is accelerated by sunlight and warm temperatures. Over time, the plastic will break down entirely and disappear from the environment.
When is it time to replace your biodegradable plastic bag?
There is no definitive answer to this question, as it depends on a variety of factors, including the type of bag, its size, and how often it is used. However, many experts believe that it is generally safe to replace your biodegradable bags every few months or when it starts to show signs of wear or tear. If you find that your bag is not breaking down as quickly as you would like it to, you may want to consider replacing it sooner.
