Paddy fields account for around 20% of human-related emissions of methane -- a potent greenhouse gas. This released Methane gas can be used for human consumption from the above method.

Production of Methane from rice fields

  1. 1. PRODUCTION OF METHANE FROM PADDY FIELDS A VISION/IDEA BY: PRASANJIT RAM & AROSEK PADHI
  2. 2. MICRO-ORGANISMS PRODUCING METHANE IN CROP FIELDS
  3. 3. Paddy fields account for around 20% of human- related emissions of methane -- a potent greenhouse gas. Farmers normally flood rice fields throughout the growing season, meaning that methane is produced by microbes underwater as they help to decay any flooded organic matter. Thus making methane harmful for the crops. We can use this methane from the paddy fields for other purposes
  4. 4. We will use small pipes with semi permeable membranes which would have activated carbons for adsorption of methane. activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions
  5. 5. This collected methane will be stored in a container for further uses. Benefits of methane : • it can be burned to produce electricity • used as a fuel for ovens, homes, water heaters, kilns, automobiles, turbines, and other things • methane produces less carbon dioxide for each unit of heat released. • methane's heat of combustion is lower than any other hydrocarbon but the ratio of the heat of combustion (891 kJ/mol) to the molecular mass (16.0 g/mol, of which 12.0 g/mol is carbon) shows that methane, being the simplest hydrocarbon, produces more heat per mass unit (55.7 kJ/g) than other complex hydrocarbons • Methane in the form of compressed natural gas is used as a vehicle fuel and is claimed to be more environmentally friendly than other fossil fuels such as gasoline/petrol and diesel
