Unlike the red meat industry the poultry industry was very reluctant to reveal what they consider to be confidential data. As a result, only broad data collection was possible. Only specific information on carcase composition was available from 4 sources. Mostly business regarded materials as only “edible” or “inedible”. There were few exceptions, where full characterisation was made.

Using data from this table, and applying the proportions attributed to human consumption or to by-products, calculations were made to assess the overall amounts of each category. A reference with respect to human consumption (AVEC) and to by-products (UKRA), is also included in the next table. The reference data actually confirms the data made by calculation, therefore lending significant credibility to the data.

2.3.4. VALUES AND CHARGES
Effectively most respondents considered this to be commercially confidential information. However, a variety of different answers were received. These are summarised below.
The figures shown are ranges according to Category or type of by-product, and should be considered as “approximations” that can be used to give a feel for the economics of the industry rather than being totally accurate. Note: This table also includes data from the egg industry, including eggshells and hatchery waste.

The lack of a clear Category 3 protein market (for animal feeding) was given as the main reason why there is no “driver” for segregation between Category 2 and 3 materials, and why sometimes materials are “down graded” to Category 2 ( with subsequent higher charge), to achieve simple lower cost actions at the slaughterhouse.
