More about Torrefaction:

  • Torrefcation increases the calorific value of the processed product.
  • The energy loss in the process is lowerthan the weight loss.
  • Torrefaction involves the heating of biomass in the absence of oxygen to a temperature of typically 200 to 400°C.
  • The structure of the biomass changes in such a way, that the material becomes brittle, and more hydrophobic.
  • Although the weight loss is about 30%,the energy loss is only 10%. 
  • During the torrefaction process a combustible gas is released, which is utilised to provide heat to the process. 
  • During torrefaction hemicellulose and ligninpresent in the wood are decomposed to some extent.
  • It increases the calorific value of the biomass.

  • UPOV’s mission is to provide and promote an effective system of plant variety protection, with the aim of encouraging the development of new varieties of plants, for the benefit of society.

 The main objectives of UPOV are:

  • Provide and develop the legal, administrative and technical basis for international cooperation in plant variety protection;
  • Assist States and organizations in the development of legislation and the implementation of an effective plant variety protection system; and
  • Enhance public awareness and understanding of the UPOV system of plant variety protection.

Key Facts:

  • In 2002, India joined the International Union for the Protection of New Varieties of Plants (UPOV) Convention.
  • The UPOV led to the introduction of some form of Intellectual Property Rights (IPR) over plant varieties.
  • Member countries had to introduce restrictions on the free use and exchange of seeds by farmers unless the “breeders” were remunerated.
