Abstract
A cellulosic feedstock composition including an oil content of up to 15% of the composition, a cellulose content of 40-99% of the composition, a hemicellulose content of 2-20% of the composition, a lignin content of less than 15% of the composition, a nitrogen containing organic compound content of less than 20% of the composition, a protein containing organic compound content of less than 20% of the composition, a mineral content of less than 5% of the composition, a sand content of less than 5% of the composition, and a dirt content of less than 25% of the composition.
Claims12
A method for producing a cellulosic feedstock composition from a solid portion of a sewage suspension comprising:
- removing said solid portion from said sewage suspension;
- removing sand from said solid portion;
- removing a mineral from said solid portion;
- and
- removing dirt from said solid portion,
- wherein the solid portion comprising cellulose is removed from the sewage suspension prior to digestion at a Waste Water Treatment Plant (WWTP),
- thereby producing said cellulosic feedstock composition.
