PERFECOAT is a multi-disciplinary project with an aim to develop paint and coating formulations with more than 25% biobased content. The project addresses three important markets for coatings: (i) high-volume, UV-curable clear coatings; (ii) waterborne trim paints for DIY; and (iii) waterborne wall paints. The project brings together diverse expertise under one hood to achieve the desired target.

The biobased contents are divided into polysaccharides, lipids and pigments. Celignis is involved in extracting xylan and chitin from terrestrial and aquatic biomass respectively and modifying them chemically and enzymatically to produce water based and UV-curable coatings.

PERFECOAT product areas


The project is linking the industrial biotechnology sector to the paint and coating sector, as the biobased products developed in the project are microbially- or biomass-derived and modified using microbially-derived enzymes. The project integrates chemical approaches with biochemical approaches to achieve the final superior quality product. The polysaccharides are both chemically and enzymatically modified separately or sequentially to obtain unique functionalities.

Celignis is involved in the modification of chitin/chitosan, xylan and alginates using both chemical and enzymatic approaches. The modification involves: hydrolysing to obtain desired molecular weight polysaccharides; grafting chemical groups (chemical and enzymatic means) on to xylan, chitosan, and alginate to produce UV-curable binders; and grafting chemical groups to convert water soluble polysaccharides to water resistant forms.

The modified polysaccharides developed for the PERFECOAT project can be used for a variety of applications outside of the paints and coatings industry.

The work programme allows the process to reach TRL of 5 by the end of the project.

Current Projects

The UNRAVEL project (UNique Refinery Approach to Valorise European Lignocellulosics) is focused on the optimsiation of a biomass pre-treatment technology. Celignis plays a key role by analysing and evaluating the extractives present in a wide variety of feedstocks and determining how they influence pre-treatment. Further info...VAMOS concerns the construction and operation of a demonstration-scale biorefinery producing lactic acid from the paper fraction of municipal waste. In the project Celignis will develop custom NIR models for the rapid at-line on-site analysis of the feedstock and process outputs. Further info...

Current Projects

Enxylascope aims at bioprospecting and producing a novel set of xylan debranching enzymes, thereby demonstrating its ability to make xylan a key ingredient in a variety of consumer products. Celignis is playing a key role, being the technical lead and responsible for the extraction and modification of xylan from biomass. Further info...This demo project involves innovative superheated steam processing of unwanted bush and invasive biomass into high-value, clean-burning, low-cost solid biofuel. Celignis will analyse feedstocks, and process outputs, and use our QTOF-LC/MS system to profile the steam condensate for high value chemicals. We will then develop a method to recover target constituents. Further info...BIO4AFRICA will empower smallholder farmers by creating value from locally available biomass. Celignis is analysing a wide range of biomass feedstocks, from a number of African countries, and providing recommendations regarding the most suitable ones, under the best conditions, for the given processing technology. We also analyse the outputs of the various processes. Further info...

Completed Projects

DIBANET was an FP7 research project, written and coordinated by Celignis founder Dan Hayes, that concerned the production of second generation biofuels from biomass feedstocks in Europe and Latin America. The advances in the state of the art of biomass analysis made in DIBANET led to the formation of Celignis. Further info...The focus of ENABLING was on supporting the spreading of best practices and innovation in the provision of biomass for the Bio-Based Industry (BBI). Celignis played a key role in the project with regards to stressing the importance of biomass composition in terms of evaluating feedstock and technology suitability. Further info...Celignis was the sole partner in SAPHIRE. The project, funded by the European Union's INNOSUP programme, concerned the production of high-value hydrogels from lignocellulosic residues. These are expected to have applications in the cosmetic and pharmaceutical sectors. Further info...This was a Marie-Curie Individual Fellowship (MCSA-IF) involving Celignis's Lalitha in which algae were used to recover nutrients from anaerobic digestion (AD) process streams.
