In the recent past, sustainable development has steered an increasing impetus in most of the developing countries. The Environmental quality is deteriorated due to the unprecedented growth of the developmental activities. Sustainable development has to ensure the optimum rate of resource consumption and minimum waste discharge for a selected development portfolio in a defined planning region, without progressively impairing its bio-productivity and ecological integrity. In the LEED point value system of Green buildings-a common standard of measurement of USGBC, 1993, the category of ‘Materials and Resources’ does not address “Biodegradability” of building materials which is a crucial component for Sustainability. Biodegradability is one of the most crucial life building mechanisms of nature to sustain its equilibrium. In the differences of the life cycle process of a Tree and a Machine, we find the former undergoes a process of Re-materialisation (i.e.; material biodegraded to base matter and energy and then again grown to a newer material), whereas the latter survives on Life Cycle concepts of Re-cycle, Reuse and Reduce. The concept of biodegradable green buildings relates to nature at a theoretical level and its application is possible with new wonder materials like Grancrete along with many traditional building materials which lead to sustainable design. Grancrete-on ceramic product, is stronger than concrete is being tested successfully for fireproof, vermin proof, termite proof, waterproof, non-toxic, biodegradable, and can be applied in a day, as a spray-on ceramic / concrete alternative. It is composed of sand/sandy soil, fly ash which is found in most part of the world, Magnesium Oxide and Potassium Phosphate. This study analyses about the re-materializing quality of Grancrete and other traditional materials which gives an option of re-inventing newer components and systems in the future from the same base matter for a sustainable world. A few important ‘concerns’ of green consciousness are discussed here which is eco-centric approach, is yet to be applied in LEED rating system.
