Guidelines for Specifications of Biochars for Use in Soils FINAL ...

1234567891011Table A4.2 is a list of feedstocks sourced from processed biomass. Any change from oneprocessed feedstock to another will constitute a “material change” in feedstock, e.g. (1) achange from sheep manure to pig manure, (2) a change from sludge/waste provided by FacilityA to that by Facility B, or (3) a significant change in the process parameters (e.g., a change inprocess chemistry for paper sludge, or a change from dairy manure to pig manure in ananaerobic digester process).Processed feedstocks not listed in this table may be used to make biochar if they meet theother feedstock requirements outlined in these guidelines.When a mix of different processed feedstocks is used, or where the processed feedstockconsists of a mix of components, a change of more than 10% in the total feedstock compositionshall constitute a “material change” in feedstock.1213Table A4.2 – Processed Feedstock TypesProcessed Feedstock Types for determining "material change" in feedstock14Cattle manurePig manureChicken manureSheep manureHorse manurePaper mill sludgeSewage sludgeDistillers grainAnaerobic digester sludgeBiomass fraction of MSWFood industry waste15161718ReferencesPhyllis, database for biomass and waste, Version: 4.13, Energy Research Centre of theNetherlands (ECN), http://www.ecn.nl/phyllis, (accessed 03 January 2012).1920International Biochar Initiative – Guidelines for Specifications of Biochars for Use in Soils 30
