Whatever the reasons, these packaging are increasingly present in areas such as commerce or catering due to their lower impact on the environment and the ease with which they can be recycled.
But how do they differ from each other? What makes them more environmentally friendly?
What are biodegradable packaging?
Environmentally friendly packaging is mainly characterized by materials with less impact on the environment, as well as the use of recycled, recyclable and biodegradable materials, especially when it comes to food packaging.
Unlike conventional plastic containers, biodegradable containers do not contain any petroleum derivatives . The manufacture of biodegradable packaging and its disposal does not produce greenhouse gases and does not present other risks associated with crude oil.
Unlike plastics, which can last for hundreds or even thousands of years, and can even be composted, these packages are made of plant compounds , which break down more easily in nature or in landfills. Essentially, the organic substrate is turned into compost, which is then used to create new plant material, which in turn creates new containers and completes the cycle.
PLA (polylactic acid) is one of the most widely used plant compounds for the manufacture of containers and utensils. This bioplastic made from lactic acid is biodegradable and can be derived from starch-rich crops, such as corn, beets, potatoes, and wheat, as well as corn, beets, potatoes and wheat, which are high in starch.
The different types of “green” packaging
Degradable packaging: Plastic packaging containing TDPA (Totally Degradable Plastic Additives) accelerates decomposition. They allow the plastic to break down faster than standard plastic.
Biodegradable packaging Most packaging and bags are of this type. The prefix “bio” indicates that living organisms participate in the decomposition of the material. The earthworms in your garden won’t become a healthy snack if you bury a biodegradable plastic bag in your garden. Furthermore, “biodegradable” and “compostable” are not synonymous.
Compostable packaging: Compostable packaging is made from materials that can be turned into compost, i.e. organic fertilizer. In addition, the packaging will be transformed without visible or toxic residues in a short time, thanks to the microbial action.
What are the benefits of biodegradable packaging?
One of them is that they reduce CO2 emissions , protect the environment and eliminate waste. Plastics are used more responsibly today. Reducing greenhouse gas emissions is also essential.
Biodegradable packaging does not generate waste . Therefore, when they decompose, no chemicals or gases are released into the atmosphere. They disappear naturally or are recycled.
One of the biggest advantages of biodegradable packaging is that it won’t pollute the environment. Also, they do not harm the environment. In fact, they are environmentally neutral .
Plastic, for example, is not recyclable and therefore pollutes the environment. Biodegradable packaging, on the other hand, is environmentally friendly. They are also relatively inexpensive to produce.
