A bio-refinery is a facility that inte­grates biomass conversion processes and equip­ment to produce fuels, power and chemicals from biomass. The biorefinery concept is analogous to today’s petroleum refineries, which produce mul­tiple fuels and products from petroleum. Indus­trial biorefineries have been identified as the most promising route to the creation of a new domes­tic biobased industry

Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the re­mains of dead plants and animals. These are sometimes known instead as mineral fuels. The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried com­bustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pres­sure in the earth’s crust over hundreds of mil­lions of years.

When generating electricity, energy from the combustion of fossil fuels is often ‘used to power a turbine. Older generators often used steam gen­erated by the burning of the fuel to turn the tur­bine, but in newer power plants the gases pro­duced by burning of the fuel turn a gas turbine directly.

ADVERTISEMENTS:

With global modernization in the 20th and 21st centuries, the thirst for energy from fossil fuels, especially gasoline derived from oil, is one of the causes of major regional and global con­flicts. A global movement toward the generation of renewable energy is therefore underway to help meet the increased global energy needs.

The burning of fossil fuels by humans is the largest source of emissions of carbon diox­ide, which is one of the greenhouse gases that allows radiative forcing and contributes to glo­bal warming. A small portion of hydrocarbon- based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.
