• Celignis Pitch for CBE 2024 Topic
    HORIZON-JU-CBE-2024-IA-05

Background

This is a topic in the 2024 work programme of the Circular Bio-based Europe Joint Undertaking (CBE-JU) which was published on December 19th 2023, with the call for proposals opening on April 24th 2024. The deadline for submitting proposals to this call is September 18th 2023, with the results expected by February 2025 and the projects expected to start later in 2025.

Celignis is an SME that was spun-out from an EU research project (the FP7 advanced biofuels project DIBANET) that was written and coordinated by Celignis's founder Daniel Hayes. It has now been over ten years since the end of that project and over that time Celignis has grown in size and reputation and now occupies a valuable niche as being the premier analytical and bioprocess development provider to clients in the biomass sector. We provide a wide range of compositional analysis services and bioprocessing expertise to a diverse array of customers (including SMEs, multinationals, and universities) looking to utilise biomass feedstocks, residues and wastes for the production of biobased products, biofuels, and energy.



But we have not lost sight of the importance of science and in advancing the start of the art. We were born from pioneering research and we are still passionately committed to playing our part in advancing the bioeconomy. As a result we continue to be highly active in European research projects and are particularly excited by the calls presented in the 2024 CBE-JU work programme.

In April 2023 Celignis joined the Bio-based Industries Consortium (BIC) as a Full Industry SME Member, meaning that we can contribute to the strategic direction and future calls of the CBE-JU and that Celignis is an eligible partner for all CBE-JU actions. The CBE requires that any Large Industry or SME partner in Innovation Action (end TRL 6/7) or Flagship (end TRL 8) projects is a BIC member.



"Celignis had successful proposals in over 40% of the CBE-JU Innovation Action topics in 2023. Our Full-Industry BIC membership and extensive scaled-up bioprocessing capabilities make us particularly suited to participation in IA proposals"


Celignis is a partner in 1 ongoing CBE project, with a further 3 (successful awardees of CBE-JU funding in the 2023 call) starting between May and Sept 2024. The ongoing project, PERFECOAT is a RIA (Research and Innovation Action) project, whilst the 3 upcoming projects (BIONEER, PROMOFER, and MANUREFINERY) are Innovation Action (TRL 6/7) projects. The extensive developments in processing capacity (up to 1m3) by Celignis Bioprocess over the last few years make us particularly suited to participation in such higher-TRL topics.

Contributions Celignis Can Make to HORIZON-JU-CBE-2024-IA-05

As a Full Industry Member of the Biobased Industries Consortium (BIC), Celignis is eligible to participate as a partner in CBE Innovation Action projects such as this one.

  • Partially depolymerised lignin stream for aromatics production - Celignis’s EnXylaScope process uses an enzymatic approach for removal of lignin from forestry and agricultural residues. This lignin is partially depolymerised and, as it is extracted at low temperatures, it is a unique product compared to kraft and sulphated lignins. The lignin is cleaner compared to other types of lignins and is a by-product of the process. Celignis believes this lignin to be highly suitable for aromatics production because of its partially depolymerised form. As the call topic asks for co-production of lignin-derived aromatics, implying production of other biobased products from hemicellulose and cellulose streams, we believe the lignin generated from the EnXylaScope process perfectly fits the criteria, as the cascading production and use of lignin, hemicellulose and cellulose streams can be demonstrated. Additionally, this topic would complement Celignis's work in the CBE-JU 2023 Innovation Action project BIONEER which focuses on the production of platform chemicals, other than aromatics, from lignocellulosic biomass.
  • Microbial production of lignin derived aromatics - Certain groups of fungi and bacteria are capable of biotransformations of aromatics in lignin, such as ferulic acid, to high value compounds such as Vanillin. Celignis has a collection of cultures (up to 200 industrially-relevant strains) that can be screened for ferulic acid transformation to vanillin. However, production of vanillin by using wild-type micro-organisms is limited. Hence, based on the previous reports on certain bacterial species, Celignis is interested to collaborate with genetic engineering experts to genetically engineer the selected strain for increased conversion efficiency. Celignis can produce Kg-scale lignin using 1.5 m3 (x2) process capacity and 0.1 m3 capacity to use the modified strain for transforming Kgs of ferulic acid rich lignin to vanillin via the microbial route.
  • Techno-economics, process modelling & optimisations - Celignis's process engineering and modelling team has years of experience in the analysis of biological and chemical processes for technical and economic feasibility (TEA). The Celignis team can identify the possible high costing nodes of the process through modelling in the early stages of the project and provide suggestions of improving the feasibility of the process. The techno-economic analysis will be done iteratively during the course of the project by performing all the necessary sensitivity analyses on key operational inputs and parameters, including the side streams valorisation or treatment.

    Celignis’s Chief chemical engineer and Bioprocess head Oscar Bedzo has a PhD in chemical engineering with a focus on biomass fractionations and enzyme transformations. He has experience in working with large industry clients through public and private projects and leads the projects very smoothly. Currently, he is doing TEA work for a number of Celignis's private projects and also for the ongoing Horizon-Europe project EnXylaScope which is developing and demonstrating the production of 6 consumer products (personal care, feed/food) from three different feedstocks.

    Celignis is also the partner for full TEA analysis for a successful CBE-JU 2023 proposal. That project (MANUREFINERY), which comprises 23 partners and 11 different technologies being proven at demonstration scale, will start in September 2024.

    Celignis’s team of biomass valorisation and bioprocess experts support the TEA analysis and perform process optimisations based on their years of experience in biomass processing technology development. We are a world-renowned bioprocess development service provider and consultant for the bioeconomy. Having Celignis as a TEA and process optimisation partner in a consortium will bring this extensive expertise to the project.


  • Extraction and fractionation of high-value aromatics derived from lignin - In Celignis’s EnXylaScope process, the two main feedstocks used are wheat straw and poplar residues. It is known that the aromatics of lignin vary between different biomass types with some feedstocks (e.g. wheat straw) high in aromatics such as p-coumaric acid, while others have more vanillin, p-hydroxy benzoic acid, vanillin, vanillic acid, syringaldehyde, syringic acid etc. In this project, Celignis can use enzyme-assisted clip-off process to release the aromatics from lignin and to produce crude aromatics powder that can be further purified. Celignis’s enzyme assisted process development together with our separation and purification expertise will be of help to the consortium for the demonstration of novel low-energy and less chemical-intensive process routes for valorisation of lignin streams. We propose this enzymatic route as a pre-step before thermo-catalysis reactions that produces a broth of aromatics which can then be separated.
  • Rapid analysis and process optimisations - As part of our Bioprocess Development Services that we provide to a range of clients, we are able to effectively optimise conditions for a wide range of processes, including biomass fractionations, and enzymatic and chemical conversions of polysaccharides. This is done by improving upstream and downstream process conditions following design of experiments and statistical data analysis. We can effectively apply these approaches to the objectives of this project.

    In addition to this, Celignis’s near infra-red models development expertise for custom feedstocks or products (>20,000 samples used for generating Celignis's global models) will help in use of this analysis for process control especially when feedstock variability can be substantial (waste streams). Our NIR expertise was effectively demonstrated in the recently-completed CBE-JU Innovation Action project VAMOS. It concerned the demonstration (TRL7) of a technology for producing lactic acid from biomass. Celignis's role in the project was as an at-scale rapid analysis developer. Work involved the development of custom rapid NIR models developed for the streams in the VAMOS project. This including us installing an NIR-device at the demo biorefinery and customising the user-side software experience (proprietary Celignis software "CelDeep") so that routine plant operators can get quick actionable data regarding the composition of feedstocks and process outputs. This allowed for much more responsive decision making and process optimisation.

    CelDeep results

  • Proposal Evaluation - In 2020 Celignis was the primary writing partner in EnXylaScope, a project specifically focused on the extraction of xylan and on its subsequent modification to be suitable as a component in a range of consumer products. This proposal was successful, and the project started in May 2021. In 2023 Celignis actively took part in writing a CBE-JU Innovation Action project (BIONEER), together with the co-ordinator, and was successful in securing funding.We were also in two other successful CBE-JU proposals in the 2023 call. Additionally, Celignis's Lalitha and Dan have worked for several years as EU Expert Evaluators reviewing CBE-JU proposals and so understand the differences between good proposals and the great ones that end up getting funded.

    As a result of these experiences, plus our Full-Industry membership of the Biobased Industry Consortium (BIC), and due to our experience in offering research and technology development services related to industrial biotech processes, we have a good understanding of the current art in this topic and how an impactful proposal with strong Excellence and Impact can be developed. As a result, we will be happy, as part of our partner constributions towards a proposal, to put forward suggestions as to how a competitive proposal can be drafted.

Expected Outcomes of CBE-2024-IA-05

Projects are overall expected to address the EU Bioeconomy Strategy and its action plan, the Chemicals Strategy for Sustainability (under the EU Zero pollution ambition for a toxic free environment), the EU Industrial Strategy, the EU Biodiversity strategy 2030, as well as and the co-implementation of the Transition Pathway for the Chemical Industry.

Project results should contribute to the following expected outcomes:
  • Scaling-up the cascading use of lignocellulosic biomass with improved atom economy, upcycling lignin. Significantly contributing to divesting from fossil resources, also considering the aromatics platform.
  • Improved sustainability, strategic autonomy, resilience and competitiveness of the European chemical industry while reducing the fossil feedstock dependence in other downstream sectors.
  • Significant improvement of environmental and safety performance across the value chain against specified fossil and/or bio-based benchmarks.
  • Availability of broader range of bio-based chemicals meeting market and technical performance requirements, facilitating the market uptake of scalable bio-based solutions.
  • Societal relevance and social acceptance of circular bio-based solutions and products.

Scope of
CBE-2024-IA-05

Aromatics production is a billion € market and the share of EU is around 25%. Aromatics have impact on applications such as solvents, agrochemicals, dietary supplements, while also being important in plastics production and other materials (e.g. resins, polyurethanes).

The demand for chemicals from renewable sources is rapidly increasing and there is an urgent need for alternative feedstock and sustainable technologies to produce aromatics in bio-based industry.

Lignin is available at large volumes and currently mostly downcycled because of the lower feasibility to obtain scaled up, selective aromatic streams, of which there are very few alternatives to fossil-based aromatics. Approximately, only 1-2% of the lignin annual production is used in chemicals production.

Proposals Under CBE-2024-IA-05 Should:

  • Demonstrate the efficient, cost-competitive and sustainable production of aromatic bio-based chemicals from lignin, including phenols, alkylphenols, BTX (Benzene, toluene and xylenes) and/or other aromatics.
  • Address the upstream processing of lignocellulosic biomass and the downstream processing of lignin to obtain targeted aromatics, demonstrating high yield and selectivity for the targeted aromatics. Under this context, consider the integration of advanced analytical characterisation capabilities of lignin and lignin-derived aromatics if applicable.
  • Describe reaction mechanisms and pathways leading to the production of the targeted bio-based aromatics in the context of further advancing process scale-up during or beyond the project duration.
  • Clarify the relevant feedstock in scope including availability and process flexibility aspects in relation to feedstock composition if relevant. The cascading valorisation of secondary biomass and residual streams is also in scope.
  • Include a task to integrate assessment based on the safe-and-sustainable-by-design (SSbD) framework, developed by the European Commission, for assessing the safety and sustainability of chemicals and materials. Under this context, projects are expected to contribute with and develop recommendations that can advance further the application of the SSbD framework. The safety and environmental performance assessment must account for the full value chain and the most relevant final application(s) and end-of-life, ensuring safety for workers, end-users/consumers as well as the environment.
  • Test and validate (end TRL: 5 and above) the bio-based aromatics for their further conversion or integration further down the value chain.
Proposals must implement the multi-actor approach and ensure adequate involvement of all key actors in the value chains relevant for this topic, across the sustainable circular bio-based system, including B2B actors, end users as well as feedstock providers.

Proposals should seek for links and complementarities and avoid overlaps with past, ongoing and upcoming EU funded projects, including those funded under H2020, HEU and the BBI JU and CBE JU. Collaboration among projects from the same topic are encouraged.

Proposals should also describe their contribution to the Specific CBE JU requirements, presented in section 2.2.3.1.

The Value Celignis Can Bring to a CBE Project


We believe that we can make valuable contributions to projects covering a large number of the topics in the 2024 CBE work programme, based on our expertise in:

Extraction of Hemicellulose Polysaccharides

To date much of the innovations related to the valorisation of lignocellulosic feedstocks has focused on the cellulose and lignin fractions. In most technologies hemicellulose is broken down in the process to either monomeric sugars (e.g. xylose) or their derivatives (e.g. furfural). However, hemicelluloses, when retained in the polymeric form, can have outstanding physical and chemical properties which make them suitable for incorporation in an array of consumer products, replacing less-sustainable product components and so allowing for greener market options for the consumer.

Celignis is the technical lead in the €6m Horizon Europe project EnXylaScope which focuses on the efficient extraction of xylan, the most abundant hemicellulose polysaccharide, and its subsequent modification to confer properties that make it suitable as an ingredient in a scope of consumer products. In the CBE/BBI project PERFECOAT Celignis is also working on extraction of xylan, from different feedstocks, so that it can ultimately be used as a binder in paints and coatings. In the CBE-JU Innovation Action project BIONEER, due to start in June 2024, we will be scaling-up to TRL7 (1.5m3 reactor-scale) the xylan extraction process developed in these projects. We consider that integrating efficient methods for extracting hemicellulose polymers within the wider biorefinery process scheme will allow for higher-value products and a more sustainable and profitable process.

Our expertise in hemicellulose extraction is therefore relevant to a large number of topics within the CBE-JU 2024 Work Programme, in particular:
Related Projects


Modification of Polysaccharides

An efficient extraction process is only one component in developing value-added products from polysaccharides. In many cases further treatment of the polymer is required in order to confer the physical and chemical properties that are required for the desired application/market. Such properties that can be influences with these modifications include the the rheology and water-resistance of the polymers.

At Celignis we also have extensive experience in such modifications using both enzymatic and chemical approaches. For example, in the Horizon Europe project EnXylaScope we are active in the discovery and application of enzymes for the debranching of xylan and for its subsequent modification for additional functionalities. In the CBE/BBI project PERFECOAT the focus is on the chemical modification of xylan in order to enhance its properties for application as a binder in paints and coatings. We consider that integrating efficient methods for extracting hemicellulose polymers within the wider biorefinery process scheme will allow for higher-value products and a more sustainable and profitable process.

In PERFECOAT we are also working on the extraction and modification of chitosan, from prawn shells, whilst we have also internally worked on processes focused on the extraction and modification of pectin. Additionally, as outlined in the video below, we have developed processes for the modification of seaweed-derived alginate to confer the desired physicochemical properties.

In the CBE-JU Innovation Action project BIONEER, due to start in June 2024, we will be scaling-up to TRL7 (1.5m3 reactor-scale) many of the polysaccharide modification approaches described above.

The ability to selectively and cost-effectively modify polymers is a key component of many topics in the CBE-JU 2024 Work Programme, in particular:

Identification, Extraction, and Purification of High Value Chemicals in Biomass

The CBE-JU recognises that biomass valorisation can involve much more than the processing of cellulose, hemicellulose, and lignin. Non-structural components of the plant can also be of value, in some cases being worth thousands of Euros per kilogramme. There are numerous examples of such high value constituents, with the most prominent recent example being the extraction, isolation, and purification of cannabinoids (in particular CBD and CBG) from hemp, which has developed into a multi-billion Euro industry.

At Celignis, we can play important roles at all stages in the valorisation of such compounds, starting from their identification and ending in their purification and the testing and modification of their functional and chemical properties. For identification, we firstly get a crude extract from the feedstock, obtained via various approaches, including pressurised liquid extraction. This extract is then profiled using our top-range QTOF-LC/MS system (Agilent iFunnel 6550), which can identify constituents to the femtogram-level, and the spectra and chromatograms reviewed by Sajna, our Bioanalysis Developer. If necessary, we can collect the relevant fractions from the LC system and confirm the identification using a number of different chemical and spectroscopic techniques. We then determine which constituents warrant extraction and then work on optimising a targeted extraction method. This method considers not only the yield of the target compound(s) but also the chemical and energy costs of the process and the implications for the downstream processing and valorisation of the solid residue, evaluated by Oscar, our technoeconomics analysis (TEA) expert. We subsequently work on the isolation and purification of the targeted compound(s) from this extract, again considering the commercial and scale-up implications.

Celignis undertook such an approach in the CBE/BBI project UNRAVEL where the extractives of 25 feedstocks were profiled using QTOF-LC/MS. We identified betulin in birch bark as the most attractive compound and subsequently worked on developing an optimised extraction protocol and an isolation/purification process scheme that offered several advantages, in terms of sustainability and safety, over the current art. Click here for a news article on this work. We are also using employing our compositional analysis and purification expertise in the Horizon Europe project SteamBioAfrica where we evaluate and process the liquid condensate obtained from the steam torrefaction process and consider market applications for its constituents, fractions, and derivatives.

Our high-value-chemicals expertise is of particular value for improving the competitiveness of a biorefinery process, through employing the principle of the cascading use of biomass. For example, a relatively minor component of biomass can substantially improve the financial viability of a technology if it can be sold at a high price. As a result, such an approach can make important contributions to a number of the 2024 topics, such as:

Real-Time Analysis of Feedstocks and Process Outputs

We have extensive expertise in the development of algorithms and models for rapidly predicting the composition of samples using their near infrared spectra. This allows the time for analysis to be reduced from weeks to seconds. To date we have tens of thousands of biomass samples in our proprietary models for lignocellulosic composition and we have also developed custom models for feedstocks and pretreatment/bioprocess outputs in the CBE-JU/BBI-JU RIA projects BIOrescue and UNRAVEL. In BIOrescue we developed custom software, employing a browser interface for the user, that allowed us to tailor the model-generation and composition-prediction experience to the requirements of our lab personnel and in-house chemometricians. This software also employed advanced chemometric techniques that we proved, in project deliverables, to deliver improved accuracies in prediction over the conventional PLS approaches.

Our NIR and software development expertise was demonstrated at-scale in the recently-completed CBE-JU Innovation Action project VAMOS. At the demo-scale facility in Swansea, UK, we installed NIR equipment and deployed our latest software, "CelDeep", for at-line analysis by biorefinery operators. The VAMOS project allowed us to extend the reach of our predictive models beyond our own laboratories and into the global biorefinery landscape.

CelDeep results


We see many opportunities, within the 2024 CBE-JU topics, to apply and refine this at-line analysis system to other IA projects as well as for Flagship projects. In addition, we also plan for the deployment of in-line analyses, using Celignis-developed models, using the latest state-of-the-art and cost-effective hardware on the market.

While there are numerous options currently on the market for NIR hardware, there is no robust solution currently available for the at-line/in-line analysis of lignocellulosic feedstocks and process outputs/residues. This is due to the complexity of such analysis, the difficulties often faced in getting precise and representative data, and the widely varying outputs of different biomass processing technologies. At Celignis, however, we have years of expertise in getting precise lignocellulosic data and in using these data as inputs to our chemometric tools. As a result Celignis provides full vertical integration regarding advancing the art in rapid biomass analysis and the utilisation of biorefinery data.

Our abilities to develop on-site rapid analysis solutions are applicable to many of the Innovation Action and Flagship topics of the 2024 CBE-JU Work Programme, including:

Compositional Analysis

As detailed throughout this website, the Celignis team are highly experienced in a wide array of methods for the compositional analysis of biomass and process intermediates and outputs/residues for lignocellulosic and thermal properties. Our expertise also extends to seaweed, algae, and a large variety of functional molecules many of which have large future potential in substituting for the use of fossil fuels in the production of consumer and industrial products.

We have an wide array of equipment that allow us to obtain the required compositional data, including an extensive chromatography laboratory that includes state-of-the-art equipment, such as our QTOF-LC/MS system.

Our in depth understanding of the steps involved in the processing of biomass also allow us to bring forward suggestions to other partners in the consortium, based on the analytical data we obtain, on how the project's technologies can be improved.

Our expertise in compositional analysis, and in the understanding and process implications of compositional data, is relevant to all of the RIA, IA, and IAFlag topics of the 2024 CBE-JU Work Programme.

Fermentation Optimisation

Microbial conversion of sugars to chemicals and fuels is considered advantageous over chemical processes, but is a challenging area due to the high number of variables involved in the process. Fermentation process development involves: selection of microbes to produce the desired product, screening of microbes, media engineering, process optimisation, scale-up, downstream designing, etc. Screening and optimisation involve hundreds of runs which is labour and time intensive. Know-how in the area of microbiology, bioprocess engineering and design of experiments (DOE) can significantly reduce the number of experimental runs and time involved in the preliminary screening and optimisation process.

With our CIO Lalitha and our Bioanalysis Developer Sajna we have the expertise and knowledge to optimise fermentation processes for high yield and productivity in short-time. Our personnel have proven scientific records in producing enzymes, biofuels, biosurfactants, exopolysaccharides and prebiotics through aerobic and anaerobic fermentation processes.

Celignis also has numerous bioreactors, ranging from 1 litre to 1.5m3 litres capacity, that allow us to undertake an extensive DoE approach in optimising fermentations.

Our expertise in fermentation is particularly relevant to the following topics of the 2024 CBE-JU Work Programme:
Related Projects


Discovery and Use of Enzymes

Our team has years of experience in discovery and use of enzymes for deconstruction of lignocellulosic biomass and, with Celignis participation in EU projects like EnXylaScope, this experience is expanded to enzymes useful for modification of the xylan fraction of lignocellulosic biomass.

The discovery of enzymes needs rapid analysis methods and, by understanding the action of enzymes and the changes that occur in the substrate, the Celignis team can develop simple high-throughput screening methods for the discovery of enzymes. This is currently being undertaking in EnXylaScope for xylan side-chain acting enzymes.

Celignis is also discovering enzymes and designing enzyme cocktails for lignocellulose deconstruction aiming at production of monomeric and oligomeric sugars and for generating clean lignin for lignin valorisation purposes. We are undertaking the scaled-up (1.5 m3 reactor-scale) deconstruction of lignocellulosic biomass to sugars as part of the CBE-JU Innovation Action project PROMOFER, which will start in July 2024.

As part of our STEAME project we are also isolating the microbes that have the ability to produce a cocktail of enzymes for increasing the productivity and yields of biogas from complex recalcitrant streams such as late cut grass, wheat straw and garden waste.

Celignis follows traditional methods in enzyme screening allowing the isolation of natural enzyme producers which means that enzyme cocktails developed by Celignis are non-recombinant in nature. The enzymes discovered are studied for various characteristics such as nature of protein (Molecular weight, hydrophobicity); kinetics (reaction and inhibition); optimum reaction conditions etc. Celignis has a collection of around 200 strains capable of producing a range of enzymes that act on a variety of substrates.

Our expertise in enzymes is particularly relevant to the following topics of the 2024 CBE-JU Work Programme:

Anaerobic Digestion and Fermentation

We have years of experience in various types of anaerobic fermentation and anaerobic digestion for the production of chemicals and fuels. The team has knowledge and experience in isolation and handling of Clostridial strains and clostridial fermentations for the production of hydrogen, organic acids and solvents. Celignis's CIO Lalitha Gottumukkala has published several articles in the area of Clostridial fermentation, especially for biobutanol. Lalitha also, during her time in Stellenbosch University, South Africa, optimised a process for the sequential production of bioethanol and biogas from paper sludge.

Celignis is using this expertise in the development of an advanced anaerobic digestion process design (STEAME) that allows high volumetric productivity and yields. This is being done as part of a nationally-funded project. In this process, the thermophilic nature of archaea is taken advantage of together with the ability of Clostridia to digest complex feedstocks. In STEAME Celignis is using expertise in biomass pretreatment together with microbial and enzyme expertise to enhance the anaerobic digestion of late-cut grass, wheat straw and other complex-recalcitrant agricultural residues.

Celignis also provides services for biomethane potential (BMP) determination; anaerobic toxicity assays; specific hydrolytic, acidogenic and methanogenic potential using its 90 1L anaerobic digestion reactors. Celignis has also the reactor set-up for continuous anaerobic digestion and sequential continuous anaerobic digestion that allows two stage and multi-stage digestion. Additionally, the Celignis team also has strong expertise in the valorisation and treatment of food industry effluent streams and is providing consultancy for three years for the operation of high-rate digesters that process 60 m3/h of dairy industry waste streams. This expertise is of particular value in EU projects where zero-pollution is the process target.

Our AD experience is particularly relevant to the following topics of the 2024 CBE-JU Work Programme:

Biomass Pretreatment and Fractionation

Based on our bioprocessing and compositional expertise, we have a very good understanding of how to optimise biomass pretreatment processes. For our clients we have analysed hundreds of samples of outputs from biomass pretreatment processes. We have a very strong understanding of the chemistry of biomass and how to evaluate the conversion and valorisation of the main constituents of lignocellulosic biomass (cellulose, hemicellulose, and lignin). We target mass-closure in our analysis so that the full mechanisms of conversion can be understood and we have a suite of analytical methods to characterise process liquids for monomers, oligomers, sugar degradation products, and fermentability. Our CBE-JU project UNRAVEL concerned the development of a pretreatment process and Celignis played a key role in the project regarding the analysis of the products of pre-treatment and by investigating the influence of extractives in biomass pretreatment. In our completed BBI project BIOrescue we also analysed the solid and liquid outputs of biomass pretreatment and developed rapid analysis models for them using near infrared spectroscopy.

Additionally, in July 2024 the CBE-JU Innovation Action project PROMOFER will start. In that project Celignis is resposible for the at-scale (1.5m3 reactor-scale, equivalent to TRL7) pretreatment and hydrolysis of lignocellulosic biomass in order to provide second-generation sugars to other partners in the consortium. We will also be involved in optimising downstream stages of the process so that the sugars delivered to the project partners will be suitable for fermentation.

Our pre-treatment/fractionation expertise is particularly relevant to the following topics of the 2024 CBE-JU Work Programme:

Process Flow Diagrams and Techno-Economic Analysis of the Process

Bioprocesses are complicated, with several upstream and downstream process unit operations to achieve the final product. Celignis's process engineering team has several years of expertise in performing techno-economic analyses (TEA) for the conversion of biomass to biofuels and chemicals. Celignis performs techno-economic analysis from the process concept design and uses it for economic optimisation of the process together with the yield optimisation. This process is done iteratively during the course of the project to achieve the process optimised for conversion efficiencies and economics. Our process engineers develop TEAs for multiple scenarios of the same process and perform sensitivity analyses to identify the major contributors of the operation's cost to allow development of economically-viable processes without sacrificing the process yields.

Celignis is developing PFDs and performing TEA for the Horizon Europe project EnXylaScope, where the analysis is being performed for enzyme production, extraction of xylans, and use of enzymes for the modification of xylans.

Additionally, Celignis is the key TEA partner for the CBE-JU Innovation Action project MANUREFINERY, which will start in September 2024.

Our TEA expertise is relevant to all RIA, Innovation Action, and Flagship topics in the 2024 CBE-JU Work Programme.

Successful Proposal Writing and Proposal Evaluation

Dan Hayes wrote the €3.7m, 14 partner, EU project DIBANET from which Celignis spun-out of whilst, more recently, Lalitha Gottumukkala wrote the €6m, 13 partner, Horizon Europe project EnXylaScope, which started in 2021. Celignis personnel have also been successful as the primary authors of proposals for the EU's INNOSUP and Marie-Curie programmes, as well as for a number of nationally funded projects (e.g. the STEAME project).

In 2023 Celignis was invited to large number of consortia for CBE-JU proposals and we actively contibuted towards the writing process for these projects. As a result, we celebrated a number of successes when the results were announced in January 2024.

In addition, both Lalitha and Dan have, for a number of years, been Expert Evaluators for proposals submitted to the BBI-JU (the precursor to the CBE-JU). As a result we have a good understanding of what makes a good proposal and what will improve the chances of a project being funded, hence we can give valued advice to proposal coordinators regarding the direction and focus of a proposal.
