ABOUT THE PROJECT

The one day Indo-Norwegian workshop is planned to bring industrialists, researchers, and academicians on a common platform to share and discuss their experiences, technical advancement, constraints and other significant issues pertaining to the topic of workshop. Issues such as increased utilization of construction and demolition waste, and mineral wastes including coal combustion residues (fly, bottom and pond ash) from thermal power plant stations, slag from steel plants in cement industries and associated limitations will be discussed. The knowledge sharing and discussions during the workshop will be useful in suggesting realistic solutions. There will be invited presentations on various themes of the project by Indian and Norwegian experts.

ENVIRONMENTAL FRIENDLY STRATEGY FOR WASTE MANAGEMENT IN INDIA:UTILISING CEMENT AND CONCRETE PRODUCTION TECHNOLOGY

This industry-oriented BILAT-INDIA project (2009-2011) between India and Norway aims to contribute to further increase the utilisation of mineral wastes in Indian cement and concrete industry in an environmental and scientific sound way in order to ensure sustainable energy and resource management. The BILAT-India project is supported by the Research Council of Norway, the Royal Norwegian Embassy, New Delhi, Borregaard LignoTech, Elkem as Materials, Orkla India Pvt. Ltd. and Norcem As. The BILAT-India project is coordinated by the SINTEF Building and Infrastructure in close cooperation with the National Environmental Engineering Research Institute (NEERI), and the National Council for Cement and Building Materials (NCB).

The principal objective of this project is to increase the utilisation of mineral waste in Indian cement and concrete industry in an environmental and scientific sound way by means of research based solutions and increasing the public acceptance and awareness of environmental benefits.

The project will advance the state of the art regarding blended cement and concrete technology as well as providing practical solutions and guidelines. Emphasis is given to the synergies achieved by using ternary binder systems in concrete mixes as well as the use of appropriate admixtures in order to integrate certain waste materials at higher levels than todays practice. The focus is on both, to further decrease the Portland clinker fraction in the cements and the virgin materials in the production of concrete by replacement with the said materials; thus reducing both CO2 emission and the exploitation of virgin materials. Moreover, internationalization of research in institutional and industrial level will be ensured to maintain competence and readiness for technologies to practice and promote sustainable future growth. It aims to use the experiences gained by the Indian partners in close relation with Norwegian partners, in order to take benefits of increased use of mineral wastes.

The project involves a systematic cross-sector mapping (thermal power plant, construction and demolition and steel industry) of the crucial factors seen as the main hindrances for increased utilisation and practical arrangements, and solutions are searched for at the waste generation site (e.g. onsite drying of ash, simple pre-treatment, mechanical activation etc.). Significant efforts are also being made on raising the awareness for all parties in the stakeholders chain through guidelines, training courses and demonstration projects. Moreover, the project proposes a strategy for how such publicity can be implemented and effectuated on a permanent basis, e.g. include the project findings in regular educational courses.

There are three major work packages (WPs) in the project and NEERI is assigned to undertake work package (WP1) on solutions sought at the waste generation site.
