Managing the water, energy and food requirements of a constantly-rising world population, in the context of climate change, is a key global challenge. Significant growth in proven and predicted fossil fuel reserves mean that achieving the Paris COP21 target for a 1.5 degree Celsius increase in mean global temperature relative to the pre-industrial level is at risk if we remain dependent upon these reserves. Biomass derived from agricultural and forestry residues is a low carbon feedstock for transportation fuels and organic chemicals. Integrating conversion processes so that biofuels, chemicals and energy are co-produced maximises the economic viability of waste biomass utilisation; an approach analogous to current petroleum refineries that deliver high volume/low value (fuels and commodity chemicals) and low volume/high value (fine/speciality chemicals) products in tandem. The potential for agricultural waste as a feedstock for low carbon fuels and chemicals is vast, even allowing for sustainable land management practices. In the EU alone, 16% of road transport fuel could be produced from waste by 2030 which would deliver green-house gas savings of greater than 60%. In Asia rice is the single most important crop, annually yielding >250 million tonnes of waste rice residues. Current practices of "at-site" burning of these waste residues in developing nations have serious detrimental effects on the environment and human health; improved waste management is therefore essential. To employ rice residues as sustainable feedstocks for transportation fuels and organic chemicals requires improved processes for their pre-treatment and conversion. This project proposes to develop an alternative, environmentally-benign process to utilise waste rice residues for the production of fuels and bio-derived agrochemicals, which will impact on renewable energy, climate change and environmental pollution by seeking to transform a plentiful waste resource into (1) an economically-viable, sustainable energy source for transportation fuels; and (2) a sustainable feedstock for the production of organic chemicals, while mitigating emissions of carbon dioxide and atmospheric particulates from "at-site" burning. We will exploit recently-established demonstrator plant facilities at ICT-Mumbai in India (ICTM) which offer cost-effective waste rice residue fractionation into lignin and cellulose, with a focus on bioethanol production. Our aim is to develop underpinning science to offer a wider range of high-value products from lignin, sugars and other extracted components thereby future-proofing the process to combat the fragile economics of bioethanol production. We propose an innovative and flexible conversion platform building on current expertise of the UK partners. A multidisciplinary team with expertise in plant cell wall deconstruction and simultaneous saccharification (Institute of Food Research; IFR), green extraction methods (The VN-UK Institute, University of DaNang), enzyme expression, tandem bio- and chemo-catalytic conversion technologies (Aston), bio-chemo routes to depolymerising lignin (Vietnam National University, Ho Chi Min City), process engineering and catalysis (Ha Noi University of Science & Technology) and photocatalytic water depollution (Aston and The Vietnam Academy of Science and Technology) will tackle the challenge of value-added product production while also ensuring sustainable water management practices are adopted. Enhanced research capacity in the Indian and Vietnamese institutes will be facilitated by interdisciplinary researcher training exchange visits to the partner research institutes at Aston and IFR, building a platform for sustainable agricultural waste management.

在气候变化的背景下，管理不断增长的世界人口的水，能源和食物需求是全球的关键挑战。经过验证和预测的化石燃料储量的显着增长意味着，如果我们仍然依赖这些储量，那么实现巴黎COP21目标的平均全球温度相对于工业前水平的平均温度相对于工业前水平的平均温度增加1.5度。源自农业和林业残留物的生物量是用于运输燃料和有机化学物质的低碳原料。整合转化过程，以使生物燃料，化学物质和能源共同生产，从而最大程度地提高了废物生物量利用的经济生存能力；类似于当前提供高量/低价值（燃料和商品化学品）和低体积/高价值（精细/特色化学品）产品的当前石油炼油厂的方法。农业废物作为低碳燃料和化学物质的原料的潜力是巨大的，甚至可以实现可持续的土地管理实践。仅在欧盟，到2030年就可以用废物生产16％的道路运输燃料，这将节省超过60％的绿色房屋汽油。在亚洲，大米是最重要的农作物，每年产生> 2.5亿吨的废水残留物。当前对发展中国家这些废物残留物的“现场”燃烧的实践对环境和人类健康产生了严重的有害影响；因此，改善废物管理至关重要。要用大米残留物作为运输燃料和有机化学物质的可持续原料，需要改进其预处理和转换的过程。该项目建议开发一种替代性，环保的过程，以利用废水残留物来生产燃料和生物衍生的农业化学物质，这将影响可再生能源，气候变化和环境污染，以寻求将丰富的废物转变为（1）经济可持续的，可持续的，可持续的，可持续的，可持续的能源的运输能量来源，以供运输厂房运输量； （2）可持续的原料，用于生产有机化学物质，同时减轻二氧化碳和大气颗粒的排放，从“燃烧”中。我们将利用印度ICT-Mumbai（ICTM）的最近建立的示威者工厂设施，该设施将具有成本效益的废水残留分级为木质素和纤维素，重点是生产生物乙醇。我们的目的是开发基础科学，以提供木质素，糖和其他提取的组件的更广泛的高价值产品，从而使未来的过程能够打击生物乙醇生产的脆弱经济学。我们建议建立一个创新且灵活的转换平台，建设在英国合作伙伴当前的专业知识上。 A multidisciplinary team with expertise in plant cell wall deconstruction and simultaneous saccharification (Institute of Food Research; IFR), green extraction methods (The VN-UK Institute, University of DaNang), enzyme expression, tandem bio- and chemo-catalytic conversion technologies (Aston), bio-chemo routes to depolymerising lignin (Vietnam National University, Ho Chi Min City),工艺工程和催化（HA NOI科学与技术大学）和光催化水的污染（阿斯顿和越南科学技术学院）将应对增值产品生产的挑战，同时还要确保采用可持续的水管理实践。跨学科研究人员的培训交流访问将促进印度和越南研究所的增强研究能力，这是对阿斯顿和IFR合作伙伴研究机构的访问，为可持续农业废物管理建立了平台。
