TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The caloric value of the cellulosic feedstock composition, combustion product composition, the ethanol containing composition, or the animal feed or animal media composition is 5000-16000 BTU/pounds. The particle size of the pulp or paper product composition is 0.01 microns to 100 mm. In the method of producing the cellulosic feedstock composition, the sewage suspension is comprised in a stream of sewage flowing in a waste water treatment plant (WWTP). Preferred Method: The method of producing the cellulosic feedstock composition comprises removing the solid portion from a stream of sewage flowing in a WWTP, where the sewage stream comprises the sewage suspension. In the method of producing the cellulosic feedstock composition: the step of removing sand is operative to decrease a sand content of the composition to less than 5% of the composition; the step of removing a mineral is operative to decrease a mineral content of the composition to less than 5% of the composition; the step of removing dirt is operative to decrease a dirt content of the composition to less than 25% of the composition; the exhausted thermal energy generated during the drying is transformed to electrical energy; the electrical energy is provided for performing the drying; and the drying yields residual minerals. The method of producing the cellulosic feedstock composition further comprises: at least partially drying the solid portion; dewatering the solid portion; or sterilizing the solid portion. The method for producing the ethanol containing composition further comprises at least: removing oil from the cellulosic feedstock; removing a protein containing organic compound from the cellulosic feedstock; removing nitrogen containing organic compound from the cellulosic feedstock; grinding the cellulosic feedstock; at least partially sterilizing the cellulosic feedstock; and at least partially drying the cellulosic feedstock. The method for producing the glucose containing composition further comprises at least: removing oil from the cellulosic feedstock; removing a protein containing organic compound from the cellulosic feedstock; removing a nitrogen containing organic compound from the cellulosic feedstock; grinding the cellulosic feedstock; at least partially sterilizing the cellulosic feedstock; or at least partially drying the cellulosic feedstock. In the method for reducing gaseous emission from a sewage management system; the removal of at least 20% of the solid biomass portion results in a reduction of at least 20% of the gaseous emission; the removed solid biomass portion is processed to produce a combustion product for replacing fossil foils, to further reduce the gaseous emission caused by combustion of fossil foils; the gaseous emission comprises a methane emission and a carbon dioxide emission; and the certified emission reduction units are earned by the reduction of the gaseous emission. The reduction of the gaseous emission in the method for reducing gaseous emission from a sewage management system comprises at least: reduction of gaseous emission during anaerobic processing of the sewage suspension within the sewage management system following the removal of the solid biomass portion from it; reduction of gaseous emission during landfilling of sludge produced by processing of the sewage suspension within the sewage management system following the removal of the solid biomass portion from it; and reduction of gaseous emission due to reduced electricity consumption during operation of the sewage management system. EXAMPLE - The raw sewage (100 m3) was introduced into a hydrocyclone centrifuge at a pressure of 3 atmosphere for initial sand and dirt removal from the raw sewage. The remaining portion was introduced into a magnet containing device where a portion of iron was magnetically removed. The raw sewage was introduced into an entrapping device formed of a net of a 250 micron mesh. Solids ( approximately 50 Kg) were entrapped within the net. The residual liquid portion was discarded. Secondary sand removal was performed by sedimentation in a conical-shaped pool where the sand sunk to the bottom of the pool. The sedimented sand was discarded. The solid portion was introduced into a sterilizer at 85 degrees C for 10 minutes. Mineral removal was performed by use of a chemical wash where the solid portion was boiled at 85 degrees C for one hour with a solution of distilled water mixed with a 37% hydrochloric acid in a boiling apparatus. The boiled solid portion was washed 2 times with deionized water. The solid portion was pressed in a screw press for partial removal of liquids from it to give cellulosic feedstock composition (comprised of (in %): oil (5); cellulose (31); hemicellulose (10); lignin (4.5); protein containing organic compound (6); nitrogen containing organic compound (6); minerals (12.1); sand (12.5); and dirt (12.9)).
