How Compostable Bags are made? | Easy-Flux.in

Easy and Profitable Process for the Making of the Compostable Bags

On the reduction of plastic bags for commercial exchanges and especially now with the recent legislation on the reduction of the consumption of plastic bags, the industry of the sector faces the challenge of manufacturing first bio plastic that will later become biodegradable plastic bags and that can also be compostable.

Composition of biodegradable and compostable bags

The bioplastic is derived from plant products such as potato starch or corn starch.

Starting from bags made from bio plastics, it already indicates that these will biodegrade in compostability conditions and in an approximate time of 9 months (at temperatures between 60 to 70 degrees Celsius and relative air humidity between 40-60%).

However, if it is not disposed of in this way, it has a shorter life in the environment compared to polyethylene, it has the ability to decompose under normal conditions in a year and a half, this also logically does not imply that you abandon them to free will.

Natural resources to replace polymers

When it is been talked about compostable bags, the polymers with which high or low density polyethylenes are manufactured, are replaced by natural resources usually potato starch or corn starch. These renewable plant-based resources make it possible to change the origin of the plastic raw material by becoming bio plastic without having to use petroleum by-products.

Properties of compostable bags

The properties of biodegradable bags are the same as those of polyethylenes, that is to say it has the same flexibility, they are very resistant, waterproof, moisture resistance.

Correct recycling of compostable bags

As for recycling, it can be deposited in a container of only organic waste (likely to become compost) but at this time there are very few containers of this type and it remains as a pending subject for municipalities, meanwhile one has to be deposit them in the “the rest” containers (that is, what is not glass, plastic, metal or paper).

Regulations for compostable packaging regulation

There is a standard that regulates compostable containers of plant origin, compostable and biodegradable, which comply the authentication standard.

This European standard specifies the requirements and procedures to determine compostability :

These requirements could be summarized in:

Composition control: the elements that make up the material and that are harmful to the environment for exceeding heavy metal limits should not be introduced, as they are not suitable for organic recovery.

And an evaluation, where the whole thing is analyzed:

The constituents of the material including heavy metals,

You can check its biodegradability which would be that in 6 months 90% has degraded,

Disintegrate in a pre-defined maximum size, that is, in fragments smaller than 2 × 2 mm after 4 months.

And above all that this resulting biological residue is suitable for compost.

When the containers have components that may not be compostable, the packaging as such is not considered compostable unless it can be easily separated by hand before disposal, which once separated can be considered compostable.

With this standard, the control of the container in waste treatment plants is taken into account, but it does not take into account packaging or packaging waste that may end up in uncontrolled means, that is, garbage.

Biodegradable materials to reduce the impact on the environment

Working with biodegradable materials will help us reduce that negative impact on the environment and that the neglect of some worsens day after day.

Commitment to the environment

Professionals and expert companies anticipating the changes that will occur with the entry into force of the new regulations of plastic bags in stores, expert companies as well as professionals are working to incorporate biodegradable and compostable materials in the entire range of products are manufactured.

Other factors to keep in mind

Cities and towns use to spend less money in the end in the removal of plastics from wastewater treatment plants. The lakes and streams are less polluted. The results lead to a more balanced and healthy habitat.

The use of this type of bags in all homes is highly recommended. These days, everyone should do their part to save the planet, and can do so by reducing the use of any product that has been proven to affect the planet. Biodegradable products are great alternatives. Best of all, it will not pose any threat to the environment.

Conclusion

These days, more countries happen to be advocating the use of compostable bags in each home. It is a better way to get a greener planet free of threats. Organic products can be bought in today's markets. More and more people are realizing the damage that the planet has been acquiring for quite some time and if everyone makes few changes in their daily habit, they can contribute to saving the planet. They should start at home and with the proper disposal of waste using ecological plastic bags.
