Interest Subvention Scheme for Energy Biomethanation Project

Recently, Ministry of New and Renewable Energy (MNRE) has launched Interest Subvention Scheme for energy biomethanation projects.

  • The United Nations Industrial Development Organization (UNIDO) and the Ministry of New and Renewable Energy (MNRE) of the Government of India have launched a loan-interest grant scheme funded by the Global Environment Facility (GET). The scheme provides financial support for innovative biomethanation projects and business models of energy generation from industrial organic waste.
  • Biomethanation projects producing energy from industrial waste generally require more capital. In addition, the operating cost of these projects is also high. There is also a challenge in the availability of waste and revenue generation.
  • Established during the 1992 Rio Earth Summit, the GEF is the largest multilateral trust fund. It enables developing countries to invest in nature. It also supports the implementation of major international environmental conventions.
  • Geographical Information System (GIS) based inventory tool for organic waste was also unveiled during the webinar.
  • This tool will provide district level estimates of available urban and industrial organic wastes and their energy generation potential across India.
  • MNRE is promoting all available technological options for setting up projects for recovery of energy from waste. It is to be known that this energy is renewable nature based agricultural, industrial and urban waste such as municipal solid waste, vegetables and other waste produced by the market as biogas or Bio CNG and in the form of electricity.

Waste-to-Energy Production Technologies

  • Biomethanation: The anaerobic (without free oxygen) decomposition of organic matter converts them into biogas. It consists mostly of methane (about 60%), CO2 (about 40%) and other gases.
  • Incineration: Complete combustion of waste (municipal solid waste or residue derived fuel) to obtain heat. This produces vapor. This steam produces electricity by means of a steam-powered turbine.
  • Gasification: High temperatures (500–1800 °C) are used in the presence of limited amounts of oxygen to decompose waste to produce synthetic gas (a mixture of carbon monoxide (CO) and hydrogen (H2)).
  • Thermal decomposition: In this, a mixture of combustible gases (mainly methane, complex hydrocarbons, hydrogen and carbon monoxide), liquids and solid residues is prepared to decompose combustible substances in the absence of oxygen.
