According to ADA officials, three proposals were submitted to the court recently. On the March 30 hearing, the apex court directed the civic body to submit the best possible method to deal with the issue at hand.

ADA's town planner Ajay Kumar Singh told TOI that a committee headed by senior administrative officials would now discuss the matter and zero in on the most effective project.

Among the three options, the wet scrubber technique is said to be the most effective one to reduce pollution level at MokshDham. Under the wet scrubber system, smoke from pyres will be passed through a water channel which in turn will reduce emission of carbon particles, supposedly one of the main causes for the 17th century white marble monument turning yellow.

Meanwhile, the court gave its approval to install an electric cremation chamber at MokshDham. This service will be free of cost.

Another proposal was offsetting a 'green' cremation system, Mokshda, which could supposedly reduces the wood requirements for burning a body to nearly a quarter of what is used in the traditional method. Around 400 kg of wood is required in the traditional method.

The third proposal was similar to Mokshda. On November 16, 2015, a bench of Justice TS Thakur and Justice C Nagappan had given three weeks' time to the Central Environment Committee (CEC) to suggest an alternate space for the crematorium near the Taj. At least 25 pyres are burnt here each day, and the ashes rising from these have been damaging the Taj, studies have found.

Later in December, the court deferred the shifting of the cremation ground and asked the authorities to look into ways of reducing carbon emission from burning of pyres as well as beautifying the place.
