Portuguese researchers have managed to create a plant material that does not pollute the environment.
The investigating team led by textile engineering at the University of Minho, Fernanda Viana and scientists at the University of Fernando Pessoa, sought and found a way to create posters that comply with the national legal framework and the result is a corn, soy and bamboo fiber that minimizes environmental impact and do not harm public health. It's an innovative idea that has emerged from an observation of everyday life, the political and advertising outdoors we see on the streets are not biodegradable, unlike prescribed by law, many are made of PVC and coated with resin.
Another novelty presented by the researchers is the application of liquid crystals. This is new technology that allows you to change the advertising message on the billboard by environmental stimuli or intentional. That is, it is possible to have different advertising or political propaganda poster in the same range by varying thermal action. These scientific discoveries have no date for its marketing, once the project is in the process of analysis of patenting, through the National Institute of Industrial Property. A less appealing aspects of the potential of this innovation are the costs that slightly exceed the non-biodegradable posters. However, scientists ensure that an enhancement of the production line in large scale can create an approximation of the power values.
