While using natural materials, one has to bear in mind the environmental and social impact of using that material. A 'cradle to cradle ' approach is adapted to do this analysis; focusing on the embodied energy of a material.
Embodied energy entails the energy that is spent in production, manufacturing, processing, transport, installation, demolition and decomposition of a material. Non- quantifiable aspects such as impact of the manufacture, processing, use and/or decomposition of a material on the socio-politico-economic structure of the region, its recyclability are also considered.
