Question

Which of the following is the technique used for energy recovery from waste?

• A. Thermal Conversion
• B. Biochemical Conversion
• C. Thermo-chemical Conversion
• D. All of the above

Answer 1

The correct option is D All of the above

• Energy can be recovered from the organic fraction of waste (biodegradable as well as non-biodegradable) through thermal, thermochemical and biochemical methods.
• In Thermal coversation, complete oxidation of waste matter under high temperature and aerated conditions takes place for the production of energy.
• In Biochemical conversation Enzymatic decomposition of waste, matter takes place for the production of energy.
• In thermochemical conservation, high temperature is driven decomposition of organic matter for the production of fuels, oils or gas.
• Hence thermal, thermochemical and biochemical conversation techniques are used for energy recovery from waste.
• So, the correct answer is 'All the above'.
