1st small production campaign bio-aromatic MPA realised

November 2, 2021

In October Relement has finished the first sample production campaign to produce >25 kg MPA at >99,5% purity of bio-aromatic 3-methylphthalic Anhydride (bio-MPA). Relement used Biorizon’s facilities at the Green Chemistry Campus in the Netherlands for this campaign. 


CTO Stefano Iannacone says he is happy with this initial production carried out with the assistance of TNO, allowing simultaneously tech transfer from TNO to the spin-off company Relement.


“It is exciting to learn about the Diels-Alder chemistry and process details to produce bio-aromatic MPA and the best way is to perform the actual process yourself. I can notice TNO has put a lot of effort in designing the chemistry and convert it into a workable process at Kg-scale and now I am keen to scale-up and improve this procedure to the next level”. 


Relement will soon start scale-up projects and collaborations with leading chemical manufactures partners toward the next stage: bigger scale demonstration. In summer 2022 a process book will be ready to allow subsequent contract manufacturing of bio-aromatic MPA starting a ton-scale.



Nieuwe aliBio-aromatic 3-methylphthalic anhydride (bio-MPA) is the first bio-aromatic Relement will launch at the market, using its versatile platform technology. The ingredient can only be made via non-edible biomass residues and can be applied in applications like coatings, specialty polymers, adhesives and material resins. 


Bio-MPA is thé missing ingredient to make a 100% renewable performance coating. Relement is the first company worldwide that can offer this biobased aromatic ingredient for coatings. Our ingredient is slightly different then the fossil ingredient, therefore it results in an even better coating. Costumer validation of bio-MPA show improved properties in coatings such as:


·       Easier film spreadability due to lower viscosity

·       Reduced yellowing effect due to UV exposure

·       Enhanced hardness and film performance


External studies show bio-MPA can lower the CO2-footprint with 3.1kg CO2 eq /kg bio-MPA compared to the fossil equivalent.
We will change the future of coating industry so that we can make a big step forward to a more sustainable planet now and in the future. All elements matter. That is Relement’s mission.

We encourage companies to take the opportunity to conduct application testing to evaluate the properties and benefits of bio-MPA in your application. Would you like to request a sample? Please contact us:

Relement won a Tech Tour Bio-Based Industries 2024 Award

November 21, 2024
Relement is honored and grateful to be among the winners of the Tech Tour Bio-Based Industries 2024 Award. The Tech Tour event highlighted >30 selected companies at the forefront of bio-based innovation, chosen through a rigorous selection process led by a panel of active investors. Our CEO Roger Blokland was on site to present our activities. He pitched about transforming sustainable biomass residues into high-performance bio-aromatics for coatings, adhesives, and materials, offering a renewable alternative to fossil-based ingredients while also enhancing product performance. The expert jury acknowledged Relement as one of the companies that is setting new benchmarks in sustainability, circular materials, and green technology. The Tech Tour Bio-based Industries 2024 event was co-organized by Bio-based Industries Consortium (BIC) and co-hosted by Circular Valley and City of Wuppertal, as well as supported by partners like Bayer, DWNRW, ZAZ Ventures, and Shaping Bio. Of course, we would also like to congratulate the other winners: Arda Biomaterials, Blue Ocean Closures, Mevaldi, Origin by Ocean, Quorium and SenseUP Biotechnology.

Collaboration project with Fontys University of Applied Sciences completed

July 1, 2024
Relement has completed its first collaboration project with Fontys University of Applied Sciences, Eindhoven (The Netherlands). During a 18 months period, a team of teachers and 21 students worked on alkyd coating research based on Relement’ launching product bio MPA. To accelerate the research, coating experts Joost van Dijk (Puroc) and Henk van den Haak (Resinconsult) advised the students with experimental setup and formulation work. A wealth of knowledge has been created supporting the commercial use of bio MPA in performance alkyd coatings. The Relement team enjoyed the project and is convinced about the effectiveness of collaborative applied research. We are thankful with at least 21 new ambassadors for sustainable chemistry! This project is partially funded with subsidy from KIEM GoChem, a joint subsidy program from the Dutch Regieorgaan SIA and ChemistryNL. 

Bio MPA production process improved

June 24, 2024
Relement has contracted R&D partners to further optimize the production process for our launching product bio MPA (3-methylphthalic anhydride), enabling us to commence industrial-scale manufacturing soon. The efforts resulted in: a leaner and more robust process; increased bio MPA product recovery; reduced formation of byproducts such as humins; reduced the use of organic solvents; reduced energy requirement. After the summer, we will select a Contract Manufacturing Organisation to begin the production of our launching product bio MPA. Join us on our mission towards a greener chemical future. Get in touch if you would like to purchase bio MPA for your coating, adhesive or composite resin. For more information please contact our CTO Stefano Iannacone: Stefano.iannacone@relement.eu 

HOBUM and Relement created high performing biobased composite material

June 17, 2024
Relement achieved an important milestone by successfully demonstrating the use of our ingredient bio MPA in high-quality composite materials. Relement worked with Hobum to create this game-changing material: a high-performance, biobased composite material with a glass transition temperature of >110 degrees Celsius. Hobum aimed to develop composites parts made of plant fibres and a vegetable oil-based resins using a resin-transfer moulding process to create a bisphenol A-free product. Hobum reached out to Relement for the utilisation of our ingredient bio MPA to replace fossil-based anhydrides such as MHHPA in their resins. After 1.5 year of testing of various formulations, the partnership hit a breakthrough with a recipe based on admergenic acid (ADA), epoxidized linseed oil (ELO) and Relement’s ingredient 3-methylphthalic anhydride (bio MPA). This resulted in a prototype car interior panel part. The composite material reached the highest % biobased (85%) and the highest glass transition temperature (Tg 95-120 °C depending on catalyst and temperature). A higher Tg results in enhanced strength, stiffness and heat resistance. There is a strong demand worldwide on availability of lightweight composite materials with high performance. Bio MPA can be a gamechanger for this industry. HOBUM recently showed all technical data at their HOBUM Innovation Exchange Webinar. Please view the complete record using the link below:
