The world-wide production of poultry has been expanded to
meet the recent very large increase in demand. In 2012, 82 million
metric tons of chicken meat were produced by the world’s major
suppliers (USDA, 2012) and it has been predicted that this amount
will be increased in 2013, especially by enhanced production in the
USA, Thailand, and Russia (USDA, 2013a). Abattoirs that kill and
process broiler chickens are widely spread throughout the world
and they generate very large volumes of wastewater that is heavily
contaminated with fatty waste. It has been reported that an abattoir
processing 200,000 birds per day generated 3.29 tons of this
type of waste in that time and half of this was located in its wastewater
(Reungying, 2005). The National Agricultural Statistics Service
(NASS) of the USDA reported that poultry processing
factories in the USA slaughtered nearly 8.6 billion birds in 2012
(USDA, 2013b). From these statistics it can be estimated that about
70,000 tons of fatty waste are separated from wastewater in the
USA every year.
