MR. VINIT PATEL CMD; AMDAVAD ENVIRO PROJECTS PVT LTD Green Buildings in India India as a nation still has a long way to go in terms of managing its construction and demolition waste. Yet with the boom in the green building industry and better understanding of waste management methodology this seems like a new horizon, which soon shall be tamed. The US Green Building Council (USGBC) recently concluded based on a study that by 2018 the Green building industry in India would see a growth up to 20%. The question we must ask ourselves is why we are seeing this change in the industry. The construction industry consumes a large quantity of energy and resources, also creates a huge amount of pollution. This is where the need for Green Building originated. Is Green Building just a clichéd marketing term or is it about much more than simple project certification? Well, Green Building is a method of building in which path braking designs are created by using radical new material to maximize the natural habitat best suited to modern urban living. The question is how we can further optimize this process. The waste generated by the construction industry both during the process of construction and the demolition of sites in India alone amounts close to 12 million tonnes a year. Traditionally construction and demolition waste has been used for land reclamation across the world or normally ends up at the landfill. In this day and age where there is a constant decline in availability of resources and a constant increase in demand for the same. The traditional liner economic model, which believes in the concept of ‘taking, making and dumping’, is outdated. What the world needs and strives to create is a model of manufacturing and development where development is maximized using the minimum amount of resources. It strives for the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The solution to this problem; ‘ Resource Recovery ‘creating a closed loop system which by means of its design is regenerative and restorative thus keeping the construction waste at its highest utility and value, wherein green building material is manufactured using waste generated by the industry. Globally Construction & Demolition resource recovery is a trend creating ripples both in the waste management industry as well as the green building industry. Be it New Zealand, the United State or Europe. LEED and BREEAM accreditation systems give a special emphasis on the usage of green building material and recovered material is naturally apt if one chooses to follow these systems. Even here in India the IGBC and GRIHA are encouraging the use of recycled construction material by the way of incentives and carbon credits. Studies have suggested that building from recovered materials reduces the overall cost of the project by close to 30%, it also drastically decreases the carbon footprint and emission that this highly energy intensive industry is responsible for. This is mainly because a lot of the emissions in the life cycle of a construction project occur during the procurement and manufacturing of the materials. Resource Recovery as a process aims to impact exactly here; where recovered material is used instead of virgin material it eliminates the need for mining and procurement of this essential raw material for the industry. As part of the process key raw materials including sand for generic use in the industry, 10mm and 20mm aggregate for concreting (RCC/PCC) and brickbats for waterproofing and road works are recovered. Using simple manufacturing techniques various products including green plasters, bricks, pavers, kerbs, block, solid blocks, manhole covers, benches, gardening pots, tree ports and landscaping products are be made. In their resource recovery in the C&D waste is being undertaken is two place New Delhi and Ahmedabad which currently which currently houses India’s largest such plant. A recent study has suggested that the construction of a three-story building generated upwards of 4 tonnes of waste; this in a country like India highlights where the 12 million tonnes a year come from. The process uses a simplified engineering system using a series of hoppers, jaw crushers, screens, and hydro cyclones to recover materials from Construction and Demolition waste. India as a nation still has a long way to go in terms of managing its construction and demolition waste. Yet with the boom in the green building industry and better understanding of waste management methodology this seems like a new horizon, which soon shall be tamed Green Building is a method of building in which path braking designs are created by using radical new material to maximize the natural habitat best suited to modern urban living SMART CITIES 54 energética INDIA · MAR | APR16
