“…9) the hard fibrous plant parts (for example pomace, seeds, stalks or seeds) are fractionated, by enzymatic or chemical hydrolysis in three basic chemical parts namely (a) hemicellulose, pentoses, 5-C polymers, (b) cellulose, hexoses, 6-C polymers and (c) lignin, phenols. These fractions will be further converted to useful chemicals such as ethanol, carboxylic acids (acetic, butyric acid acetic acid), butanol, acetone and others [48,73]. A biorefinery requires, nevertheless, a demanding capital investment and, if based in one major conversion technology, the cost of outputs for the consumers is increased.…”

Grape wine is among the most important alcoholic beverages in the globe, with a continuously rising world demand, currently sizing at 25 billion litres. Such a large and heavily industrialised market calls for the maintenance of a steady production of raw materials to end products. Consequently, intensive cultivation of land, harvesting of the goods and manufacturing for the production of commercially available products are being implemented. Wine making is a timed, multistage process producing a large amount of organic and inorganic waste. It has been calculated that during cultivation and harvesting about 5 tonnes of solid waste are generated per hectare per year, while the winery wastewater varies according to the production size from 650,000 m 3 (Greece) to over 18,000,000 m 3 (Spain) per year. Conventional treatments of winery waste are becoming increasingly expensive, demanding significant amounts of effort, resources and energy for safe waste discharge. Therefore, the need to recycle, reuse and recover energy and valuable chemicals from winery waste and wastewater becomes apparent. Valorisation of winery waste is possible when introducing the concept of biorefinery, i.e. the use of winery waste as bioconversions feedstock in order to produce platform chemicals, biofuels, heat and energy.

ABSTRACT:The biofuel mix in transport in the UK must be increased from currently exploited 3.33% to the EU target mix of 10% by 2020. Under the face of this huge challenge, the most viable way forward is to process infrastructure-compatible intermediate, such as bio-oil from fast pyrolysis of lignocellulosic biomass, into biofuels. New facilities may integrate multiple distributed pyrolysis units producing bio-oil from locally available biomass and centralised biofuel production platforms, such as methanol or FischerTropsch liquid synthesis utilising syngas derived from gasification of bio-oil. Alternative to bio-oil gasification is hydrotreating and hydrocracking (upgrading) of bio-oil into stable oil with reduced oxygen content. The stable oil can then be co-processed into targeted transportation fuel mix within refinery in exchange of refinery hydrogen to the upgrader. This paper focuses on the evaluation of economic and environmental sustainability of industrial scale biofuel production systems from bio-oils. An overview of bio-oil gasification based system evaluation is presented, whilst comprehensive process reaction modelling (with 40 overall bio-oil hydrocracking and hydrotreating reaction steps), simulation, integration and value analysis frameworks are illustrated for bio-oil upgrading and refinery co-processing systems. The environmental analysis shows that the former technologies are able to meet the minimum greenhouse gas (GHG) emission reduction target of 60%, to be eligible for the European Union (EU) Directive's 2020 target of 10% renewable energy in transport, whilst at least 20% renewable energy mix from an upgrader is required for meeting the EU GHG emission reduction target.Increases in the price of biodiesel and hydrogen make co-processing of stable oils from bio-oil upgrader using refinery facilities economically more favourable than final biofuel blending from refineries and create win-win economic scenarios between the bio-oil upgrader and the refinery. The range of the cost of production (COP) of stable oil (328 MW or 0.424 t/t bio-oil), steam (49.5 MW or 0.926 t/t bio-oil) and off-gas or fuel gas (72.3 MW or 0.142 t/t bio-oil) from a bio-oil (LHV of 23.3 MJ/kg) upgrader process is 2 evaluated based on individual product energy values and global warming potential (GWP) impacts. The minimum and the maximum annualised capital charge predicted by the Discounted Cash Flow (DCF) analysis correspond to 25 operating years and 10% IRR; and 10 operating years and 20% IRR; respectively. Based on this DCF strategy and 1200 $/t of hydrogen and 540 $/t of biodiesel market prices, the selling prices of 259.32 $/t, 34.85 $/t and 174.27 $/t of the stable oil, steam and fuel gas, respectively, from the upgrader to the refinery were obtained to create win-win marginal incentive for the upgrader and refinery systems, individually. If stable oil from a bio-oil upgrader can be launched as a product potentially to be used in refinery hydrocracker (at a competitive price of 490 $/t), for the production of rene...
