There is possibility of still having high starch concentration ln waste compared to when the processing was mechanically effected; though the percentage starch would still vary since the performance of the machines differs. The protein content was determined from the Bradford graph and the results summarized ln the table Other components such as fats. ash etc make up the remaining percentage of 6%. The values obtained are comparable to the composition of some common cellulosic materials according to Ayhan
