Abstract: Large scale urbanization and industrialization has aggravated the already existing
environmental problems in India. Wastes production is an inevitable outcome of all the
industrial activities. Most of the wastes generated from industries are hazardous in
nature. These hazardous wastes generated from industries needs proper treatment,
storage and disposal owing to their perilous characteristics. The capital city of India;
Delhi produces 5281 million tonnes of hazardous wastes every year. The hazardous
wastes generated in the capital is not being treated and disposed adequately due to the
absence of secured landfill facility, incinerator and other provisions for their
appropriate management. Thus the quantum of wastes is increasing and with this the risk
of contamination, spillage and pollution also is increasing. The project was aimed at
determining suitable treatment, storage and disposal options for the different hazardous
waste streams identified (as per schedule 1), if a TSDF (Treatment, Storage and
Disposal Facility) comes up in the city. Information was collected on the quantum of
wastes generated from industrial processes, characteristics and quantities of wastes.
Also recommendations were made on the utilization of wastes as AFR (Alternate Fuel
and Raw Material) in the cement industry. Monitoring requirements for closure and post
closure were also identified.
Key words: Hazardous wastes, Treatment, Storage, Disposal, Delhi,
