In the third excerpt from MVW Lechtenberg & Partner’s Alternative Fuels & Raw Materials
Handbook, Dirk Lechtenberg describes the use of poultry litter as an alternative fuel for cement
and lime. Due to be published in the summer of 2011, the handbook will give an insight into
over 80 different types of alternative fuels and raw materials with detailed descriptions of the
availability, common use and practice in the cement industry.
More than 50 billion chickens are reared annually as a source of food for their meat and eggs.
Chickens farmed for meat are called broiler chickens, whilst those farmed for eggs are called egg-laying hens
or layers. The UK alone consumes over 29 million eggs every day and some hens can produce over 300 eggs a
year. Chickens will naturally live for six or more years, but after 12 months, the hen’s productivity will start
to decline and this the point when most commercial laying hens are slaughtered. In egg-producing farms, birds are typically housed in rows of cages, called batteries. Environmental conditions are automatically controlled, including light duration, which mimics summer day length. This stimulates the birds to continue to lay eggs all year.
