Today we have access to all kinds of products and information that puts us in check when it comes to thinking about our daily practices. somosrealmente aware of environmental pollution we generate every day? What everyday practices can develop for improving our quality of life?
If nosdetenemosaobservarnuestra behavior as consumers and as producers of objects that generate pollution, easily not be able realize that almost all of the objects we buy come packaged in plastic. From food through porlosenvases which we use daily in our home to bottles of water or soda among others
In principle, it is fair to mention that the plaśtico is a product of high durability and inexpensive that also has the remarkable ability to adequately protect foodstuffs and everything that we wish to preserve, for example from moisture.
In addition, and in contrast to the above, we have to mention that the plastic also has its proysuscontras, yalrespectotrabajanincansablemente, loscientificosquebuscan develop alternatives. I.e., durability property can be a positive aspect regarding its use and recycling possibilities, but it is a very negative aspect for the environment, let us always remember that when the plastic is discarded it is highly polluting.
The challenge for biotechnology
Biotechnology is a discipline in francocrecimientoydesarrollopermanente, our country, scientists are already developing tasks that allow disenaryponerenmarchaun special kind of biodegradable plastic, i.e. seansusceptiblesdesertransformados in simple substances by the action of living organisms.
An extremely interesting, sustainable and environment-friendly alternative is since the initiative has as main objective, get disposable plastic products may be disposed of quickly and do not pollute the environment.
Scientists and engineers doomed to the production of biodegradable plastics thinking to create a material that is economically sustainable, as well as being eco-friendly are developing the product from the use of starch, and do so using a special material which is produced naturally by plants as a resource.
Also seeks to develop the material from the use of other natural resources such as cereals and potatoes or tubers containing enough starch to be transformed into plastic and they happen to be a resource that is abundant on the continent, it is an ideal to be transformed into plastic resource.
In this sense, has been to develop a type of biodegradable material made of the potato starch that could replace the polyethylene employed, for example, in agriculture to cover soils and thus prevent the emergence of weeds and reduce the amount of irrigation water.
Another option is to remove the corn or potato starch and then transform it into a small molecule, called lactic acid, by the action of micro-organisms.
Lactic acid is extracted to be then treated chemically and then make polymers, which are joined together to give rise to the plastic called PLA (polylactide).
This complex process allows that from this kind of biodegradable plastic production to advance in the production of other types of resources that objects that are highly polluting for Earth such as disposable diapers and bags.
Another alternative is to use bacteria that produced inside a plastic called polyhydroxyalkanoate (PHA) granules. Bacteria can grow in cultivation and the plastic be extracted easily.
Biotechnology in our country and the world is developed through research that seek to improve the quality of life of the citizens, develop materials that do not damage the environment and which are economically sustainable.
