7 Evolution of biorefining technologies 3G 2G Lignocellulosics (e.g. straw) - selective fractionation by recyclable biosolvent - co-production of ethanol and other products 1G Lignocellulosics (e.g. straw) - non-selective chemical and mechanical pretreatments - (bio)chemical hydrolysis and fermentation to ethanol Food: sugar & starch - fermentation to ethanol
8 formico - the true 3G platform Cellulose products Paper fibres Paper, board, tissue High value fibres Viscose, CMC, Nano Non-Food and Non-Wood biomass Cellulose Hemicellulose Lignin, nutrients Glucose Ethanol, butanol, Lactic acid, succinic acid Hemicellulose products Pentose sugars Xylose, arabinose Platform chemicals Acetic acid, furfural Lignin products 3G formico biorefinery integrates biomass conversion process and equipment to produce multiple fuels, power, heat, platform biochemicals and fibres from biomass 3G formico biorefinery is analogous to petroleum refinery, which produces multiple fuels and products from petroleum Lignin Polymers, plastics Biocoal Steam, electricity Nutrients Fertilizer
9 First implementations of the 3G formicobio technology Cellulose products Non-Food biomass Glucose Ethanol, chemicals Cellulose Hemicellulose Lignin, nutrients Hemicellulose products Sugars Ethanol, chemicals Platform chemicals Acetic acid, furfural Lignin products Biocoal Steam, electricity

13 Principles of techno-economic calculations of biorefining Ethanol Sales as fuel ethanol Biomass (e.g. straw, bagasse) Biorefinery Battery limit of calculations Lignin, stillages, steam condensate Furfural, acetic acid Sales to chemical industry or treated as effluent Biomass composition Cellulose C5 in hemicelluloses C6 in hemcelluloses Power plant Steam, electricity Lignin and other components Energy sales (power to the grid, steam, )
14 Key economic variables affected by fractionation or pretreatment Accessibility and ease of hydrolysis of cellulose Yield of glucose from cellulose Required enzyme dose Conversion of hydrolysis of hemicelluloses (i.e. share of hemicelluloses that react into soluble sugars) Reactions of hemicellulose sugars (solubilized sugars react further, especially into furfural) Recovery and sales of reaction products of hemicelluloses Acetic acid (all processes hydrolyze acetate esters present in hemicelluloses) Furfural
15 Lignin in lignocellulosic feedstocks Lignin is present both around and between cellulose fibrils Pictures taken from - Koch G (2008) Raw Material for Pulp. In: Sixta H (ed) Handbook of Pulp. Vol. 1. Wiley-VCH Verlag. - Gullichsen J (1999) Fiberline Operations. In: Gullichsen J & Paulapuro H (eds) Papermaking Science and Technology, Book 6A, Chemical Pulping. Fapet Oy
16 Lignin in lignocellulosic feedstocks Behaviour during fractionation or pretreatment Presence in hydrolysis Impact on the performance of hydrolysis formicobio Almost complete dissolution (e.g. 96%) is achieved during biomass fractionation. Minor concentration in cellulose (e.g. 2% of cellulose). Absence of lignin improves the access of enzymes reduces the required enzyme dose increases yield of hydrolysis improves overall economics Typical 2G Remains insoluble. Almost all of the original lignin is present in hydrolysis (e.g. 50% of cellulose) both around and between cellulose fibrils. Presence of lignin hinders the access of enzymes increases the required enzyme dose decreases the yield of hydrolysis impairs overall economics
17 Reactions of hemicelluloses 1. Hydrolysis of hemicelluloses into sugars: polysaccharides hydrolyze into sugars O O OH OH O OH OH OH OH O O OH O OH Polysaccharide chain Sugars 2. Reaction of hemicellulose sugars OH OH OH O OH C5 sugars Furfural 3. Generation of acetic acid by hydrolysis of acetate esters of hemicelluloses
18 Reactions of hemicelluloses Hydrolysis of hemicelluloses into sugars Reaction of hemicellulose sugars Hydrolysis of acetate esters of hemicelluloses formicobio Almost complete hydrolysis (98%) is achieved during biomass fractionation. Controlled conversion of C5 sugars into furfural from 10% upwards. Furfural is recovered as a co-product. Almost complete hydrolysis takes place during biomass fractionation. Acetic acid is recovered as a co-product. Typical 2G High conversion is targeted but it is limited by further reactions of sugars. 85% is a practical figure, a part of hemicelluloses hydrolyze during enzymatic hydrolysis. Around 10% of C5 sugars react further, mainly into furfural. Furfural is not recovered and it is treated as waste. Almost complete hydrolysis takes place during biomass pretreatment. Acetic acid is not recovered and it is treated as waste.
19 Product yields of biorefining formicobio Typical 2G Yield of glucose from cellulose (enzymatic hydrolysis) 90% 80% Yield of glucose from cellulose, kg/t biomass Yield of ethanol from cellulosic glucose, kg/t biomass Conversion of hydrolysis of hemicelluloses 98% 90% Yield of sugars from hemicelluloses, kg/t biomass Yield of ethanol from hemicellulose sugars, kg/t biomass Enzyme consumption (relative figure) Generation of chemicals Acetic acid, kg/t biomass Furfural, kg/t biomass (treated as waste) 10 (treated as waste) Overall product yield, kg/t biomass
