Se conoce fabricar este tipo de bandejas con diversos materiales termoplásticos rígidos no porosos que resultan demasiado pesadas para las normas de20 extend downward, distributed adjacently evenly forming a grid. It is known to manufacture this type of trays with various rigid non-porous thermoplastic materials that are too heavy for the standards of
25 seguridad e higiene laboral. Además, este tipo de materiales plásticos no son reciclables y por tanto suponen una fuerte carga sobre el medio ambiente cuando deben eliminarse después de su utilización. Para solucionar los mencionados problemas de25 occupational safety and health. In addition, these types of plastic materials are not recyclable and therefore pose a heavy burden on the environment when they must be disposed of after use. To solve the aforementioned problems of
30 peso y de contaminación ambiental, se conoce la utilización de semilleros a base de poliestireno expandido que si bien son mucho más ligeros, presentan inconvenientes derivados de la porosidad del material, ya que son fácilmente penetradas por el sistema radicular de los plantones, lo que dificulta su extracción y también son muy propicias al desarrollo de hongos que deben ser tratados con funguicidas, perjudicando ambos el crecimiento de los plantones y que constituyen una fuente de contaminación tras su utilización. Para solucionar estos problemas se han propuesto la aplicación en el interior de los recipientes de cultivo de un recubrimiento no poroso lo que resulta inaceptable desde el punto de vista de los costes de fabricación. También sería posible pensar en un aumento de la densidad del material de poliestireno expandido, pero esto conduciría a un peso elevado que tampoco resulta aceptable conforme a las recomendadas normas de seguridad e higiene laboral.30 weight and environmental pollution, it is known to use seedbeds based on expanded polystyrene that although they are much lighter, they present inconveniences derived from the porosity of the material, since they are easily penetrated by the root system of the seedlings, which makes their extraction difficult and they are also very conducive to the development of fungi that must be treated with fungicides, both harming the growth of the seedlings and that constitute a source of contamination after use. To solve these problems, the application inside the culture vessels of a non-porous coating has been proposed, which is unacceptable from the point of view of manufacturing costs. It would also be possible to think of an increase in the density of expanded polystyrene material, but this would lead to a high weight that is also not acceptable according to the recommended occupational health and safety standards.
