The theoretical minimum net calorific value, 9net,min,theor, is material specific. It depends on the temperature and other conditions required by the combustion process. In ISO 18605 it is identified as Ha and may be determined by the method described in Annex A. This Annex specifies the theoretical minimum net calorific value through the technical concept of calorific gain.
The real minimum net calorific value, 9net,min,real. is set to allow optimization of energy recovery in a real industrial system and is defined in Annex B.
To allow optimization of energy recovery in a real industrial system, the theoretical calorific gain shall be well above zero. To claim energy recovery 9net shall be equal to or greater than 9net,min,real, as defined for various incineration conditions listed in Table B.2 in Annex B.
NOTE 1 Packaging composed of at least 50 % (by weight) of organic content, e.g. wood, cardboard, paper and other organic fibres, starch, plastics, provides calorific gain and meets the requirement of 9net equal to or greater than gnet,min,real, as defined for various incineration conditions listed in Table B.2 in Annex B.
NOTE 2 Packaging consisting of more than 50 % by weight of inorganic constituents, e.g. inorganic fllers and layers, is recoverable in the form of energy, provided 9net is equal to or greater than 9net,min,real, as defined for various incineration conditions listed in Table B.2 in Annex B.
NOTE 3 Packaging consisting of more than 50 % by weight of inorganic components, of which the primary constituent is not energy recoverable, e.g. glass or rigid metal containers with a plastic closure, is not deemed to be energy recoverable.
NOTE 4 Thin gauge aluminium (typically up to 50 um thick) contributes to 9net of the packaging and is deemed to be energy recoverable. Aluminium over 50 um is not deemed to be energy recoverable.
NOTE 5 Substances hazardous to the environment are addressed in ISO 18602. Other aspects regarding packaging not suitable for energy recovery are also discussed in Annex C.ISO 18605 pdf download.
