Poultry litter is an organic waste in Syria which can be a source of clean
energy if treated anaerobically. This research aimed to investigate the effect of
mechanical pretreatment of poultry litter in producing biogas and methane.
Experiments wer
e performed in units of fermentation laboratory on samples
ground spread over parts diameters 1 mm, 3 mm, and 10 mm at at 37°C
temperature, for a period of 42 days and compared with untreated samples
mechanically.
