The sugar cane industry is the second-largest agro-based industry in India and supports approximately 60 million farmers and their families. The sugarcane and associated industry however produces more than100 million tons (MT) of solid and liquid wastes every year (~80 MT of bagasse, ~10 MT of press mud, 45 billion litres of spent wash, bagasse pitch and ~25 MT of cane trash). Part of the bagasse is used to generate power by burning it in boilers. The huge quantities of wastes produced by sugar and associated industries pose a significant challenge as well as an opportunity. The vWa project is aimed at harnessing UK expertise on transforming waste biomass to energy and chemicals for providing technological solutions to address problem of waste generated by sugar and associated industries in India. Two leading bioenergy companies in UK (Nova Pangaea Technologies and Green Fuels Research) are collaborating with three UK universities (Queen's University Belfast, Cranfield University and Nottingham University) to develop appropriate solutions for transforming five major waste streams (bagasse, press mud, spent wash, bagasse pith and sugar cane trash) to transportation fuels (bio-CNG and butanol) and chemicals (succinic and lactic acid). The UK consortium has identified relevant Indian partners which include an apex R & D organisation of sugar mills, Vasantdada Sugar Institute (which has 146 sugar mills and 74 distilleries as their members), two large sugar mills (Dhampur and Lokmangal), a start-up focussed on pre-treatment (Vivira) along with three Indian research Institute (Indian Institute of Technology Bombay & Delhi and Indian Institute of Petroleum). The vWa consortium will address the key challenges in valorisation of a lignocellulosic biomass (LCB) namely development of a cost effective pre-treatment method (combination of cavitation, thermal and biological) to improve digestibility of biomass, transformation of treated biomass to fermentable sugar (after detoxification) and transformation of the sugars to products. Most of the past and ongoing efforts focus on pre-treatment for recovering cellulose from LCB and then converting it to sugars and other value added products. These approaches suffer from high costs associated to pre-treatment. In this project, we aim to develop and commercialise technologies for transforming five waste streams mentioned above to transportation fuels (bioCNG and biobutanol [BB]), and two value added chemicals (succinic acid [SA] and lactic acid [LA]). The key innovation lies in hybrid pre-treatment methods: thermal process (developed by Nova), hydrodynamic cavitation (developed by PI, Vivira) and anaerobic digestion (AD). The AD will be used for the first time to selectively convert hemi-cellulose to biogas and retain cellulose in the digestate which will be converted to sugars. Lignin from the digestate will be separated from the residue and may be sold as a by-product for further valorisation. The sugars obtained from digestate will be subjected to microbial fermentation to manufacture BB, SA and LA. The process conditions and strategies will be optimized and intensified & modular processes will be developed to obtain BB, SA and LA of desired purity from the fermentation broth. The proposed approach and aimed solutions will realise a step change in the state of the art. The developed solutions will be demonstrated on pilot and field scales wherever possible. These demonstrations and industry connect of the consortium partners will be used to facilitate commercialisation of developed technologies. The developed solutions will make tangible difference in productivity of sugar cane industries in India and will therefore have significant beneficial impact on wellbeing of large population in rural India.

甘蔗产业是印度第二大农业行业，并为大约6000万农民及其家人提供支持。然而，甘蔗和相关的行业每年生产超过1亿吨的固体和液体废物（约80吨的渣酱，约10吨的新闻泥，450亿升来的花水，渣hagasse的山顶，〜25吨甘蔗垃圾）。一部分渣the用于通过在锅炉中燃烧来产生动力。糖和关联行业产生的大量废物构成了重大挑战和机会。 VWA项目旨在利用英国在将废物生物量转化为能源和化学品的专业知识，以提供技术解决方案，以解决印度糖和相关行业产生的废物问题。 Two leading bioenergy companies in UK (Nova Pangaea Technologies and Green Fuels Research) are collaborating with three UK universities (Queen's University Belfast, Cranfield University and Nottingham University) to develop appropriate solutions for transforming five major waste streams (bagasse, press mud, spent wash, bagasse pith and sugar cane trash) to transportation fuels (bio-CNG and butanol) and chemicals (succinic and lactic酸）。 The UK consortium has identified relevant Indian partners which include an apex R & D organisation of sugar mills, Vasantdada Sugar Institute (which has 146 sugar mills and 74 distilleries as their members), two large sugar mills (Dhampur and Lokmangal), a start-up focussed on pre-treatment (Vivira) along with three Indian research Institute (Indian Institute of Technology Bombay & Delhi and Indian Institute of石油）。 VWA联盟将应对木质纤维素生物质（LCB）的价值挑战，即开发具有成本效益的预处理方法（空化，热和生物学）的结合，以提高生物质的消化率，以便将生物量转化为糖糖（糖化后的糖化糖）和糖转化的产品。过去和正在进行的大多数努力都集中在预处理上，以从LCB中回收纤维素，然后将其转换为糖和其他增值产品。这些方法遭受与预处理相关的高成本。在该项目中，我们旨在开发和商业化技术，以将上述五个废物流转化为运输燃料（Biocng和Biobobutanol [BB]），并将两种增值化学物质（琥珀酸[SA]和乳酸[La]）转化为运输燃料（Biocng和Biobobutanol [bb]）。关键创新在于混合预处理方法：热过程（由NOVA开发），流体动力空化（由PI，Vivira开发）和厌氧消化（AD）。该广告将首次使用，将半纤维素有选择地转化为沼气，并将纤维素保留在消化液中，该纤维素将转换为糖。消化酸盐的木质素将与残留物分离，可以作为进一步价值的副产品出售。从消化料中获得的糖将受到微生物发酵的生产，以生产BB，SA和LA。将对过程条件和策略进行优化，并加强模块化过程，以从发酵肉汤中获得BB，SA和LA的BB，SA和LA。拟议的方法和瞄准解决方案将实现最新技术状态的步骤改变。开发的解决方案将在可能的情况下在飞行员和现场尺度上证明。财团合作伙伴的这些示范和行业联系将用于促进开发技术的商业化。开发的解决方案将使印度甘蔗行业的生产力有形，因此对印度农村地区庞大人口的福祉产生重大有益影响。
