Abstract

Metal casting is one of the most energy intensive manufacturing processes. A large amount of energy is particularly consumed in the melting operation. Consequently adoption of energy efficient melting technologies by foundries is a win-win option. Improvements in energy efficiency not only reduce energy costs, but also have the potential of generating additional revenues through sale of carbon credits. Seeking carbon credits by developing appropriate clean development mechanism (CDM) projects based on energy efficiency improvements promises to be a win-win option for Indian foundries. While the primary benefit of the CDM project would be the savings in energy, additional revenues through sale of certified emission reductions (CERs) could help in improving the project returns.

The paper also highlights some of the major options to reduce energy consumption in melting furnaces. It also describes the process for acquiring carbon credits by registering a CDM project.

It also provides an overview of what carbon credits are and how the foundry unit may seek additional income by selling the carbon saved by reducing their energy consumption.

Finally, the paper discusses an actual CDM project for foundry units located in Belgaum in the state of Karnataka and a few barriers to implementing similar projects among foundry cluster elsewhere.

Helping to keep casting at the forefront - 18 June 2008

Helping to keep casting at the forefront of technology

With the development over the last couple of decades of a wide range of additive layer manufacturing (ALM) technologies, rapid prototyping has become a recognised method for the creation of both aesthetic and functional components. It now plays an integral part in the development process of new designs and concepts.
