SPECIAL REPORT: Bio Methacrylic Acid
France-based Global Bioenergies has reached the first milestone in its development of bio-based
methacrylic acid (trademarked under BioMA+) using renewable isobutene feedstock. Methacrylic acid
is a key intermediate in the production of methyl methacrylate (MMA). This milestone resulted in the
company unlocking a €1.7 million payment from the French Investissements d’Avenir State program. The
French State had granted a €5.2 million financing to a consortium that included Global Bioenergies,
Arkema and CNRS. The objective was to develop and demonstrate at pilot scale a complete process of
producing isobutene from a renewable resources and converting isobutene into methacrylic acid.
Global Bioenergies started up an industrial pilot plant in November 2014 on the agro-industrial site of
Pomacle-Bazancourt where BioAmber used to have its bio-succinic acid tolling facility. ARD, a subsidiary
of the sugar refiner, Cristal Union, is in charge of the pilot’s operation, and now carries out on a weekly
basis, fermentation trials mimicking the exploitation of bio-isobutene to MA at full-scale.
Global Bioenergies has been able to produce more isobutene in the last three months than over the past
five years. The company said the oil price meltdown does not affect its fundamentals in the short or medium
term because of the expectation that the oil market’s equilibrium will be back before its commercialisation
of bio-isobutene process, which is projected to begin in the 2017-18 time frame. The isobutene process is
said to be competitive with crude oil at $50/bbl in specific markets.
There are other companies currently developing either bio-based MA or its ester derivative, methyl
route; using the isobutylene feedstock route; or via a isobutyric acid route, which can be dehydrogenated
to MA. Methacrolein can also be obtained from formaldehyde and ethylene.
Mitsubishi Rayon (MRC), through its subsidiary Lucite International, has been developing several bio-based
MMA routes either by using biomass for feedstock in the existing production processes, or using a novel
one-step fermentation route to produce bio-MMA. According to Lucite, all of its major raw materials can
be potentially sourced from bio-feedstocks such as acetone from the ABE fermentation process; bioethanol
can be converted into bio-ethylene; or bio-methanol can be made from biogas or from the gasification of
domestic waste.
Lucite is currently working with a number of companies to investigate the feasibility of bio-acetone production
as well as to evaluate the introduction of bio-methanol and bio-ethylene into its MMA manufacturing
for MMA feedstock. Lucite has been running its Alpha Technology at a commercial scale since 2008 with
a 100 ktpa petro-MMA plant in Singapore.
Lucite said its bio-based MMA project is ongoing as the company addresses many technological challenges
in designing complex new biochemical routes. The fermentation process must be able to deliver high
concentrations of the product at acceptable output rates and at an economical level. The company noted
that customers’ attitudes towards lowering their environmental footprint, especially in the coatings industry
is a positive note towards further development of plant-based MMA.
Specialty chemicals company, Evonik, through its Creavis business unit, is also working on bio-based
MMA using a fermentation process that can convert syngas to pure 2-hydoxyisobutyric acid (2-HIBA).
Evonik has partnered with LanzaTech for its gas fermentation expertise. Evonik is already offering in the
market its VISIOMER® Terra methacrylate monomers partially based on bio-renewable raw materials.
The VISIOMER® Terra IBOMA uses a main raw material, camphene, produced from pine tree resin. The
product enables formulation of paint resins with a lower VOC content, and reduces resin viscosity.
Evonik’s VISIOMER® Terra C13-MA and VISIOMER® Terra C17.4 MA are based on natural oils and
are typically used to increase the hydrophobicity of resins. The products improve water repellency and
resistance to polar solvents.
