Some biopolymers used at the moment in the elaboratiopn of packages for H2O and wraps or envelopes for vegetables and fresh meats are the PLA (polylactic acid) and the PHA (polyhodroxy alkanoates). It is the chemical structure the one that differenciates to a biodegrable polymer of which it is not it and allows that it can be attacked by microorganisms, like fungi and bacteria in bioactives atmospheres.&lt;br /&gt;&lt;br /&gt;A useful proposal for the development of the plastic industry in harmony with the nature would be the one to make cascade  use of the natural resources, so that first application of the plastic or chemical industry has a life utility inside like from bioplastics , for example, and later biogasoline become , aside from their use in agriculture.&lt;div class="blogger-post-footer"&gt;&lt;script type="text/javascript"&gt;&lt;!--

Algunos polímeros biodegradables usados actualmente en la elaboración de envases para H2O y wraps o envolturas para vegetales y carnes frescas son el PLA (ácido poliláctico) y el PHA (polihidroxi-alcanoatos).&lt;br /&gt;&lt;br /&gt;Es la estructura química la que diferencia a un polímero biodegradable de uno que no lo es, y permite que pueda ser atacado por microorganismos , como hongos y bacterias en ambientes bioactivos.&lt;br /&gt;&lt;br /&gt;Una propuesta útil para el desarrollo de la industria plástica en armonía con la naturaleza sería la de hacer uso en cascada de los recursos naturales, de manera que primero tengan una vida útil dentro dela aplicación de la industria plástica o química, como en bióplásticos, por ejemplo y después se conviertan en biogasolina y bioenergía, aparte de su utilización en la agricultura.&lt;div class="blogger-post-footer"&gt;&lt;script type="text/javascript"&gt;&lt;!--
