Preface
Inedible meat, poultry and fish by-products are major contributors to the
profitability of the slaughterers and processors of all types of muscle food.
Although the by-products per se make important economic contributions
to the productivity of the industries, their importance varies widely
between classes and for different species. As important as this may be, the
utilization of the otherwise waste by-products has become even more
crucial from the standpoint of protecting the environment. Hence, the
editors decided that a book dealing with inedible meat, poultry and fish
by-products would be useful not only to slaughterers and processors, but
also to those involved in research and teaching. Focusing on the advan
tages of the useful inedible products and methods involved in their pro
duction could very well lead to new and better uses for by-products as well
as in improving the environment.
As in past volumes of this series, the authors are leaders in their
respective fields of discussion. Their expertise provides not only a back
ground on present industrial practices but also areas and means for
improving the production of by-products.
The first chapter (1) provides an overview on the importance of meat,
poultry and fish by-products and puts them into perspective relative to
their economic contributions. The next two chapters (2 and 3) discuss the
processes involved in turning hides, pelts and skins into leather and their
use in producing finished leather and leather products. The following
chapter (4) covers the wool pullery and production of pulled wool along
with the disposal and use of animal hair. Chapter 5 covers production and
utilization of blood meal, meat and bone scraps, and tallow. The next
chapter (6) discusses inedible fats and greases and their reclamation and
uses by industry, including feeding to animals. Chapter 7 covers soaps and
detergents and their manufacture. Chapter 13 focuses on production of
pet foods as a user of inedible by-products from the meat, poultry and fish
industries, which provides a major market for such products.
Other topics discussed include the production and utilization of
feathers, feather meal and other poultry by-products (Chapter 8), fishery
vi Preface
by-products (Chapter 9), sporting goods (Chapter 14), pharmaceutical
and biological products (Chapter 12) and production and utilization of
inedible gelatin and glue (Chapter 10).
Three other chapters focus on problems involved in disposal of waste
material as fertilizers and/or recycling through feeding back to other
animals (Chapter 11), composting and land application (Chapter 15) and
finally reduction of pollution and reclaiming other packinghouse waste
(Chapter 16). The last chapter also discusses water conservation, air
pollution and noise abatement. Overall, this book should bring readers up
to date on utilization of inedible meat, poultry and fish by-products.
