CSIR-CBRI: R&D, Regulation & Collaboration for C&D Waste Management
Prof. R. Pradeep Kumar, Director, CSIR-CBRI, focuses on the role of R&D institutions, government regulation, and industry collaboration. He highlights the need for raising awareness, conducting targeted research, and establishing a robust regulatory framework to ensure sustainable C&D waste management.
In recent decades, our country has been rapidly aspiring to become the largest economy in the world. We have already reached the fifth stage in this journey, and we are on track to achieve Stage 3 and beyond soon. As the country continues to grow, there will be a significant demand for infrastructure. Since gaining independence in 1947, many buildings have been constructed, and as time passes, these structures will either be replaced, demolished, or possibly have their lifespans extended. However, the real challenge arises when these buildings are demolished, creating what is known as Construction and Demolition (C&D) waste. While various statistics suggest that approximately 1 million tons of C&D waste are generated daily worldwide, there is no reliable scientific method to accurately measure how much is being discarded. For many, including contractors, it is often easier to simply dump this waste somewhere, which is not only irresponsible but also a crime. There is untapped wealth in this waste, and by dumping it in unsuitable locations, we are missing valuable opportunities.
There are three key players in addressing this issue: first, the knowledge base, which includes R&D institutions like CSIR-CBRI. Second, the regulatory mechanism, which is the role of the government. Third, and equally important, is the industry, which drives the entire process. These three entities are crucial for sustainable management of C&D waste.
Recognizing the need for a sustainable approach, a group of scientists at CSIR-CBRI decided to come together and discuss the challenges. The first issue identified was the lack of awareness, both among the general public and stakeholders. Raising awareness about the responsible use of C&D waste is the first step. The next step involves figuring out how to reuse this waste, which requires dedicated R&D. Without this, R&D organizations might focus solely on producing publications or patents, which, while valuable, do not necessarily yield immediate benefits to society at large. Therefore, we must identify the challenges faced by the industry, which is the second priority. Finally, and most critically, the entire process must be brought under a regulatory framework; without this, sustainable management of C&D waste is impossible. These three elements—awareness, industry collaboration, and regulation—are all essential for success.
