New constructions are being erected scraping the skies with nearly 1000m high. And still in spite of all the advances a large percentage of people of the world live in misery without the minimum of nourishment, clean drinking water and decent housing. Industries are demanding more and more raw materials, existing now mainly in developing countries and creating havoc on earth searching for and exploiting the lands holding these needed raw materials. Nature is responding with climate changes, freak storms and other disasters. The big centralized industries are not able or rather not willing to stop polluting our environment by reducing carbon emissions. Their ambition is to be the owners of the Earth, and do what they think is good for their bottom line, and not the working people of the planet. Now, sustainability goes together with moderation, meeting basic needs and a general well-being of the population. Sustainability of our environment makes possible that a greater part of the population can follow up a life’s dream or at least ability to have a decent meaningful life through preserving remaining natural resources available for the future generations. In schools and universities, yet, only the industrial non-renewable materials such as cement, concrete, steel and recently composites made of polymers research and application. The study of Non-Conventional Materials and Technologies, NOCMAT, has been started in the years of the seventies of the last century. A new line of research has been initiated to investigate local renewable materials such as bamboo, vegetable fibers, soil composite, which is called Kah-gel in Persian language. These materials have been used as construction materials for thousands years, recycled materials, such as rice husk and sugar cane ash among others. This paper will present the recent results of research on NOCMAT and their application in practice. To improve the durability of the studied materials, nano-particles applied in kah-gel and also impregnated into bamboo culm. To achieve the final objective to tune a fine nanocoating of vascular bundles’ of bamboo, internal wall has been done through the interfacial compatibility, based on self-assembling interactions, between the NFs-surface and the lignin-cellulose walls of bamboo vessels.
