The fact is that India is perched precariously on the knife-edge of energy availability. Solid waste disposal is a major environmental problem in all our cities; a problem that is compounded by the limited availability of landfill spaces. Simultaneously, our lifestyle requirements are changing rapidly, and these translate directly into increased waste generation and energy consumption. We have little choice but to look at new ways of using the natural resources that we need for sustenance in residential complexes, and to minimize waste generation during construction and occupation.
