New Journal Publication by Celignis

A new peer-reviewed article by Celignis founder Daniel Hayes has been published. It concerns the use of our NIR models to analyse the lignocellulosic composition of a variety of papers and cardboards.

The article is published in the Faraday Discussions journal and Daniel Hayes will present this work, along with additional information concerning the Celignis NIR models, at the Faraday Discussions conference, entitled "Bio-resources: feeding a sustainable chemical industry", being held in London between June 19-21.

The abstract of the paper is copied below and please click here to access the full article.


Analytical data and quantitative near infrared (NIR) spectroscopy models for various lignocellulosic components (including Klason lignin and the constituent sugars glucose, xylose, mannose, arabinose, galactose, and rhamnose), ash, and ethanol-soluble extractives, were obtained for 53 samples of paper and cardboard. These samples were mostly the type of materials typically found in domestic wastes (e.g. newspapers, printing paper, glossy papers, food packaging). A number of the samples (48) were obtained by separating a sample, after milling, into two particle size fractions. It was found that the fractions containing the smaller particles typically had higher ash and Klason lignin contents and lower glucose and xylose contents that the larger particle size fractions. Nevertheless, all of the sample types had attractive total sugars contents (>50%) indicating that these could be suitable feedstocks for the production of biofuels and chemicals in hydrolysis-based biorefining technologies. NIR models of a high predictive accuracy (R2 of > 0.9 for the independent validation set) were obtained for total sugars, glucose, xylose, Klason lignin, and ash and with values for the Root Mean Square Error of Prediction (RMSEP) of 2.36%, 2.64%, 0.56%, 1.98%, and 4.87%, respectively. Good NIR models (R2 of > 0.8) were also obtained for mannose, arabinose, and galactose. These results suggest that NIR is a suitable method for the rapid, low-cost, analysis of the major lignocellulosic components of waste paper/cardboard samples.

We Now Determine Chlorine Content

We have added another analyte to our analytical services. We can now determine the chlorine content of biomass samples. Our analysis protocol follows standard method EN 15289:2011 (Solid biofuels - Determination of total content of sulfur and chlorine). This method invovles the digestion of the sample in our bomb calorimeter followed by a rinsing of the bomb and analysis of these washings using our ion chromatography system.

We have tested our protocols with standard reference materials and found our results to be in very close agreement with the certified values. Our method is suitable for samples with low ppm chlorine contents and also those with much higher amounts of chlorine.

Currently, you can determine the chlorine content of biomass using analysis package P35 - Chlorine and Sulphur or using our comprehensive analysis package P40 - Combustion Package which also involves proximate and ultimate analysis of the sample as well as a determination of its heating value.

Presentation at IBioIC Conference

Celignis CEO Daniel Hayes will today give a presentation on Celignis at the 3rd Annual Conference of The Industrial Biotechnology Innovation Centre (IBioIC) which takes place at The University of Strathclyde's Technology and Innovation Centre (TIC) in Glasgow.

Daniel's presentation will be in the "Member's Showcase' as part of the "Impact" session of the conference.

If you are also attending the conference then you are welcome to have a chat with either Daniel or Celignis's Laboratory Analyst Christopher Comerford, who will also be attending.

New Addition to the Celignis Team

We are happy to announce that Christopher Comerford has joined the Celignis team. He will work as a Laboratory Analyst, undertaking analysis and supervision of all our biomass analysis methods. He will also assist in the development of quality management protocols and standard operating procedures as part of our development for ISO17025 accreditation.

Chris is a recent graduate of Horticultural Science at University College Dublin and also has experience working in an ISO17025 accredited laboratory. He was our first choice from a competitive field of 125 applicants for this position and we look forward to his contributions towards the continued growth of Celignis.

We are Looking for a PhD Candidate


The Irish Research Council's Employment Based Programme provides co-funding for a student to undertake a PhD associated with a university but based in a company.

We are looking to make an application for a research project focused on the development of new algorithms for rapid biomass analysis predictive models. This will involve the use of software such as MATLAB or the open-source alternative Octave.

The evaluators of the proposal will consider the innovation potential and impact of the proposed project as well as the calibre of the PhD applicant. It is therefore important that the candidate is the right fit for the proposed research programme.

Applicants should be adept with computational software, and programming experience (particularly with MATLAB/Octave) would be a major plus.

Applicant with high-level degrees (i.e. a 1st or 2-1) in a related discipline would be preferred. The scheme also allows current undergraduate students to apply providing that they will graduate in 2017 and are expected to achieve a high level degree.

Prior experience with chemometrics would also be desirable.

The scheme has had a pre-call announcement which can be viewed here. The call will officially launch on December 8th 2016 with the deadline for submission being February 16th 2017. If the application is successful then the PhD would start in October 2017 and last 3 years.

If you are interested in being our chosen candidate for this application then please send a cover letter (specific to the role described) and a CV to The candidate we choose will be expected to make significant input with regards to the content of the proposal to be submitted to the IRC.

The placement will be in our laboratory in Limerick, Ireland and will most likely be associated with the University of Limerick.

New Analysis Package for Starch

We can now determine the starch content of your biomass samples with Package P14.

Starch, a polymer of glucose units, functions as a sugar store in many plants. It is a mixture of two polysaccharides: amylose and amylopectin. You can obtain more information about starch at our dedicated webpage for this constituent.

If starch analysis is not carried out then it is possible that, in our analysis packages for determining the lignocellulosic sugars, some of the glucan could come from starch. However, if we do quantify starch then we subtract the starch content from the glucan content determined in those analysis packages ensuring, when water soluble sugars are also removed by using one of our extraction packages, that the glucan content that we report comes from lignocellulose.

We follow a Megazyme method for the determination of starch in biomass. Specifically, we use AOAC Official Method 996.11 for our analysis. This is very similar to the NREL Laboratory Analysis Procedure 'Determination of Starch in Solid Biomass Samples by HPLC' (17/07/2005).

Please refer to our Package P14 webpage for more information on our starch analysis.

Work Has Started on a New Research Project

Today marks the launch date of BIOrescue, a research project funded by the Biomass Based Industries (BBI) subset of the European Union's Horizon 2020 Programme.

The BIOrescue project targets to develop and demonstrate a new innovative biorefinery concept based on the cascading use of spent mushroom substrate (SMS) supplemented by wheat straw and other seasonal underutilised lignocellulosic feedstocks. It is expected that this new concept will avoid disposal and allow for the production of some biodegradable bio-based products and bioactive compounds that will help to replace the existing ones based on fossil resources. More information on the expected impacts of the project can be found on its webpage on the BBI website.

Celignis is one of 11 participants in the BIOrescue consortium. Our roles within the project include the analysis of various biomass feedstocks and process intermediates and residues (using our NIR models and chemical analysis methods) as well as developing new methods and algorithms to improve the breadth, depth and precision of our rapid analysis techniques.
