The Gorai dump yard that has been scientifically closed has made it among the top 100 innovative projects that make cities sustainable across the globe, according to a report ‘Infrastructure 100: World Cities Edition’ released by KPMG, a global advisory firm.
The report to select innovative infrastructure projects, which was recently released at the World Cities Summit in Singapore, was aimed at identifying challenges faced by cities globally with the innovations acting as an inspiration to planners.
“The closure has had a major social impact as the dump was located next to residential areas, posing health risks and contaminating local water supplies,” read the KPMG report. The projects were selected based on scale, feasibility, technical or financial complexity, innovation and impact on the society.
In 2009, the dump yard was closed following a 2006 Bombay high court order. The 19.6 hectare site has been transformed into a garden spread, where 2,200 tonnes of garbage was dumped every day till about four years ago.
Thirty-six wells under the gardens trap methane gas and toxic leachate water emitted from the 2.3 million tonnes of compressed garbage accumulated since 1972. The captured gas is burned before being released into the environment as harmless air through a chimney.
This will earn the Brihanmumbai Municipal Corporation (BMC) about Rs96.5 crore through carbon credits under Clean Development Mechanism under the Kyoto Protocol, a first for an Indian civic body.
“The garden will take around two years to open for the public,” said Pundlik Awate, executive engineers, solid waste management project, BMC.
