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基础产业，为大约6000万农民及其家庭提供支持。然而，甘蔗及其相关产业每年产生超过1亿吨的固体和液体废物（约80吨甘蔗渣，约10吨压榨泥，450亿升废洗液，甘蔗渣沥青和约25吨甘蔗垃圾）。蔗渣的一部分通过在锅炉中燃烧来发电。制糖业和相关工业产生的大量废物既是一个重大挑战，也是一个机遇。vWa项目旨在利用英国在将废弃生物质转化为能源和化学品方面的专业知识，为解决印度制糖和相关工业产生的废物问题提供技术解决方案。英国两家领先的生物能源公司（Nova Pangaea Technologies和Green Fuels Research）正在与三所英国大学（贝尔法斯特女王大学、克兰菲尔德大学和诺丁汉大学）合作，开发合适的解决方案，将五种主要的废物流（甘蔗渣、压榨泥、洗涤废渣、甘蔗渣和甘蔗垃圾）转化为运输燃料（生物压缩天然气和丁醇）和化学品（琥珀酸和乳酸）。英国财团已经确定了相关的印度合作伙伴，其中包括糖厂的顶级研发组织，Vasantdada糖业研究所（其成员包括146家糖厂和74家酿酒厂），两家大型糖厂（Dhampur和Lokmangal），一家专注于预处理的初创企业（Vivira）以及三家印度研究机构（印度理工学院孟买和德里和印度石油学院）。vWa联盟将解决木质纤维素生物质（LCB）增值的关键挑战，即开发一种具有成本效益的预处理方法（空化，热和生物相结合），以提高生物质的消化率，将处理过的生物质转化为可发酵糖（解毒后），并将糖转化为产品。大多数过去和正在进行的努力集中在预处理中，从LCB中回收纤维素，然后将其转化为糖和其他增值产品。这些方法的缺点是预处理费用高。在这个项目中，我们的目标是开发和商业化将上述五种废物流转化为运输燃料（生物柴油和生物丁醇[BB]）和两种增值化学品（琥珀酸[SA]和乳酸[LA]）的技术。关键的创新在于混合预处理方法：热处理（由Nova开发），流体动力空化（由PI， Vivira开发）和厌氧消化（AD）。AD将首次用于选择性地将半纤维素转化为沼气，并将纤维素保留在消化液中，这些纤维素将转化为糖。消化液中的木质素将从残渣中分离出来，并可作为副产品出售以进一步增值。从消化液中获得的糖将进行微生物发酵，生产BB、SA和LA。将优化和强化工艺条件和策略，并开发模块化工艺，以从发酵液中获得所需纯度的BB、SA和LA。提出的方法和目标解决方案将实现技术状态的阶段性变化。开发的解决方案将尽可能在试点和现场规模上进行演示。这些示范和财团合作伙伴的工业联系将用于促进已开发技术的商业化。开发的解决方案将对印度甘蔗产业的生产力产生切实的影响，因此将对印度农村大量人口的福祉产生重大的有益影响。
