Biodegradable bags contaminate the outdoors at least 3 years after instillation of

Humanity struggles with pollution in many ways — for example, in some countries, instead of the usual plastic bags used counterparts with the addition of degradable materials. Many people believe that biodegradable bags disappear very quickly, but researchers from the University of Plymouth has proved that it is not so. Being outdoors, in soil or under water, they can be stored for more than three years and stay durable.

To prove this, scientists have studied five types own recycled bags with biodegradable components. They were retrieved from the ocean, dug from under the ground and is found outdoors. The researchers carefully examined the area they lost for three years, and how a change in their chemical structure. To their surprise, some of them could even go to the store — they are so well preserved that could withstand a lot of products.

I was really surprised that any of the packages can still accommodate a lot of stuff even three years later. When you see something marked in this way (both biodegradable), I think you automatically assume that it will deteriorate faster than normal packages. Our study shows that this is not so.

The best result on the decomposition showed compostable bags — in the water they disappeared three months after disposal. In the soil they is also well settled, however, the flaps could find even after 27 months. Biodegradable and oxo-biodegradable bags, in turn, retained its strength even after 3 years.

Researchers believe that people need to be reminded what really means the word “biodegradable”. According to them, they can completely decompose only after industrial processing, and in the natural environment it is important effects of microbes, oxygen, humidity, time and other factors.
