Advantages and disadvantages of the different types of bags
The plastic bags have become part of everyday life, however, they cause a great environmental impact from the time they are made until they are discarded. In view of the great contamination they pose and trying to comply with the rule of the 3 R’s (Reduce, Reuse and Recycle), new alternatives have been created for the eradication of plastic bags. Thus, other types of bags have been invented, of different materials, all with their advantages and disadvantages.
The cloth bag can be used many times, every time you go shopping, which is a great reduction of plastic bags. In addition, there are many models with very attractive designs. However, it must be borne in mind that raffia is not biodegradable and cannot be recycled since their composition is very complex.
Potato starch bags are biodegradable, they can be broken down into nutrients and biomass that occur under natural conditions. This means that they are disposable, so their life is short. In addition, they usually carry in their composition a high percentage of petroleum compounds.
The photodegradable bags are degradable. It is a type of plastic that comes from polyethylene’s and, when mixed with an additive called Politbatch Deg, polyethylene degrades under the unique influence of light and heat. As a disadvantage, they do not come from a renewable source and, if the degradation is not controlled, the fragments in which it breaks can leak into the aquifers.
Paper bags can be recycled in a simple way, since they come from a recyclable source, however, they increase the demand for paper and they are disposable. They also break easily and, if they get wet, their recycling will be of poorer quality.
Plastic bags can be recycled. For this to happen, they must be deposited in the yellow containers for packaging. In the treatment plants they are transformed into plastic granules, polyethylene pellets and used to make other products. It has a great disadvantage and that it takes hundreds of years to degrade, which has caused major environmental problems due to the inability of humans to control them.
After reviewing the types of bags, there is one thing to mention, the best option of all these bags is one that is not used.
