Capitalising on the situation of inadequate supply of liquefied petroleum gas from India and weak market monitoring in the country, LPG bottling plants have been supplying full cylinders of cooking gas in the black market.Cylinders of various brands of LPG that are fully refilled are easily available in the black market though Nepal Oil Corporation has barred bottling plants from dispatching full cylinders in the market.Along with the scarcity of the commodity, NOC had instructed bottling plants in October to dispatch only half-filled cylinders in the market so that more number of people could avail LPG.
