Biodegradable materials are considered those materials that can be destroyed by microorganisms. To prevent the accumulation of non-biodegradable compounds in nature, there are two solutions that are currently under investigation: use roots or microbial strains that can attack thought products were not degradable, biodegradable materials or develop common strains.
The biodegradable plastics made from corn starch or wheat are being manufactured currently on an industrial scale and used, for example, for waste bags. The degradation of these plastics require a period of six to twenty four months, underground or in water, at the rate of incorporation of starch.
Similarly, the plastics made from compressed fiber rye or completely biodegradable plastics can replace petroleum. One of them, rye starch, is in the form of granular materials for manufacture of plates.
The composition and the lamination process, you get data like density, elastic modulus, tensile strength, deformation, etc.. The characteristics of these materials are very similar to those of conventional polymers of petrochemical origin.
Moreover, in the field of agriculture, biodegradable materials also offer undeniable advantages. Biodegradable materials, after being recycled, incinerated and compounds, byproducts such as water, carbon dioxide or methane, with the possible production of biomass is not toxic to the environment. These materials mixed with other elements allow to obtain fermentable compound fertilizers.
Keep in mind also that the first applications of synthetic biodegradable polymers have emerged in the field of health in the decade of the años’60. There biostable compounds used as permanent aid, as in the case of prostheses and artificial organs, and the compounds bio reabsorvibles for aid for a limited time: The time of healing. The latter biodegradable materials are used in various forms, such as for sutures or delivery systems for controlled drug.
In the automotive industry is also developing the use of biodegradable materials: interior doors filled with cars that already exist now in flax, for example, and automakers are considering plant fibers bumper reinforced by a resin biodegradable. Biodegradable materials are a great ecological footprint calculation alternative.
