.2. Biomass sources
The proposed model includes two types of feedstock to be transformed into energy: waste biomass in the form of animal manure and energy crops. In this regard, three types of waste biomass, namely cattle manure, laying chicken manure and broiler chicken manure, and an energy crop, corn silage, are considered as feedstock to be used by bioenergy plants. Available biomass amount is assumed to increase gradually with a prespecified rate. Data about the biomass potential from husbandry and agriculture is gathered from Turkish Ministry of Food, Agriculture and Livestock.
