Finding new alternative affordable and sustainable products is a
trend already well established among the research community
worldwide. People are also much more concerned about environmental
issues and demand sustainable solutions for all aspects of
their daily life. Reusing, recycling and saving are terms learnt by
children at an early age. The present world economic crisis also
requires contention, and new affordable and sustainable products
are desirable. On the other hand, the quality of these products also
has to be guaranteed. Affordability, sustainability and quality are
therefore the three main vectors which should dictate the design
of such product. To fulfill these three requirements is the big challenge.
Using organic materials and low technological processes is a
good option to achieve the above requirements [1–3]. These organic
materials have to be preferentially abundant and local.
