CHEERS: Producing novel non-plant biomass feedstocks and bio-based products through upcycling and the cascading use of brewery side-streams

生物技术有可能减少人类活动对自然界的影响。通过开发新的生物基生产平台，更有效地利用废物流，可以实现工业循环的一步。CHEERS是一种新的生物炼制概念，灵感来自自然生物多样性（昆虫和微生物平台），以可持续和有效的方式将生物基工业中未充分利用的或废物侧流（如甘蔗渣、废水、二氧化碳和甲烷）升级为创新的生物基产品。CHEERS将帮助生物基工业提高其原料使用效率、整体可持续性和竞争力，通过升级循环和级联使用从其侧流生产的生物质。CHEERS是一个模块化的解决方案，生物基行业可以通过选择5种新的生物技术路线来配置最佳组合，从而产生5种具有吸引力市场机会的工业应用生物基产品：昆虫蛋白、消毒剂、微生物蛋白、生态碱和己酸。所有价值链都基于新的生物工艺和/或创新的生物发酵罐，并结合可持续的下游工艺，这将在工业啤酒厂的示范规模上进行验证。在每个价值链中，碳足迹至少减少45%。对CHEERS影响的评估将超越传统的LCA，并将涵盖生物多样性和土地利用等更广泛的影响。MAHOU啤酒公司是项目协调员，与5个欧洲国家的11个合作伙伴合作，包括技术供应商、最终用户和研究实体。CHEERS将为“零废物”生物炼制方法做出贡献，与欧盟绿色协议、循环经济行动计划和生物经济战略完全一致，并通过从小型生物产业到消费者的相关参与者的参与，促进对生物技术价值链的理解。

Biotechnology has the potential to reduce the impact of human activities in nature. By developing new bio-based production platforms towards a more efficient use of waste streams, a step forward in industrial circularity can be achieved. CHEERS is a new biorefinery concept, inspired on nature biodiversity (insect and microbial platforms), to upgrade sustainably and efficiently underused or waste side streams such as bagasse, wastewater, CO2 and CH4 from bio-based industries into innovative bio-based products. CHEERS will help bio-based industries to improve their feedstock use efficiency and overall sustainability and competitiveness via upcycling and cascading the use of biomass produced from their side-streams. CHEERS is developed as a modular solution where bio-based industries can configure the optimal combination by selecting among 5 novel biotechnological routes which generate 5 bio-based products for industrial applications, with attractive market opportunities: insect protein, disinfectant, microbial protein, ecotoine and caproic acid. All value chains are based on new bioprocesses and/or innovative bio fermenters combined with sustainable downstream processes, which will be validated at demo-scale at an industrial brewery. A min. 45% carbon footprint reduction will be achieved in each value chain. The evaluation of CHEERS impacts will go beyond the classic LCA and will cover broader impacts such as biodiversity and land use. The beer company MAHOU is project coordinator working with 11 partners of 5 European countries, including technology suppliers, end-users and research entities. CHEERS will contribute to a “zero waste” biorefinery approach, fully aligned with the EU Green Deal, Circular Economy Action Plan and Bioeconomic Strategy, and foster the understanding of biotechnology-based value chains through the engagement of relevant actors, from small bio-based industries to consumers.
