Draft PPS18: Renewable Energy
Annex 1 Technology: Agricultural Sources of Biomass
The most commonly used fuels in this category are straw (which should be viewed as an agricultural product, rather than a residue) and chicken litter. Straw is utilised in whole bale form, and is generally sourced from within a 50 mile radius of the plant. Chicken litter consists of a mixture of wood shavings, straw or other bedding material and poultry droppings. It is a good fuel for electricity generation with nearly half the calorific value of coal.
