GoI: Quota Allocation Procedure for import of Calcined Pet Coke initiated

On April 20, 2020, the Government of India has laid down procedure to allocate quota for the import of calcined pet coke in the financial year 2020-21.

Highlights

In October 2018, the Government of India permitted imports of certain quantity of pet coke in order to use it as fuel in anode making. Earlier, the GoI had banned import of pet coke. Import of petcoke was allowed only in lime kiln, cement, gasification and calcium carbide industries. Now the Directorate General of Foreign Trade has invited applications for import of pet coke.

Pet Coke is mainly used in aluminium industry as raw material.

Pet Coke imports

India is the largest consumer of pet coke in the world. India imports over 27 million tonnes of pet coke from US alone. Pet coke emits over 11% more green house gases than coal.

What is Pet Coke?

Petroleum Coke is called Pet Coke. It is rich in carbon and is derived during oil refining. It consists of more than 80% of carbon.

Facts Box: Methanotrophic Bacteria Culture first time in India

The Agharkar Research Institute of Pune has isolated 45 strains of methanotrophic bacteria. These bacteria are capable of reducing methane emissions in rice plants.

Highlights

Apart from isolating the strains, the scientists have also created methanotrophic culture. The isolated bacteria were from southern and western India.

What are Methanotrophs?

Methanotrophs are environmental organisms that have a major role in cycling of methane. They oxidize methane in the environment. The methanotrophic bacteria oxidize methane through anaerobic metabolism. The methanotrophs are used as bio-inoculants.

What are Bio-Inoculants?

Bio-Inoculant are strains of bacteria, algae or fungi. They take in nitrogen from atmosphere and prepare nitrates required for plants. By this, use of fertilizers are reduced. They also increase zinc and phosphorous availability for plants.

Benefits

After carbon-dioxide, methane is the second largest green house gas contributor. With the use of methanotrophic bacteria in agriculture, emission of methane shall be greatly reduced. Methane traps 84 times of heat trapped by carbon-dioxide.
