Honeywell’s Technology Chosen By Vioneo For Its Planned European Production Of Fossil Feedstock-free Plastics

Vioneo and Honeywell announced today that Honeywell’s technology will be used by Vioneo as part of its plans to produce plastics using green methanol, at a new facility to be built in Antwerp, Belgium. Vioneo will use Honeywell’s advanced methanol-to-olefin (MTO) conversion technology to produce plastics without the need for traditional feedstock made from fossil fuels.

Honeywell's advanced MTO technology will enable Vioneo to use green methanol, containing only biogenic carbon dioxide, in place of coal and crude oil in its plastic production processes. This can avoid the high carbon emissions associated with fossil fuel-derived plastic, while still supporting the production of propylene and ethylene – essential components used in various everyday items such as medical equipment, food packaging, automotive parts, personal care products and toys.

“Vioneo aims to help transition the plastics industry by demonstrating that large-scale, cleaner production is economically viable using green methanol as an alternative to fossil fuel. This initiative offers Europe a chance to lead the €5 trillion chemicals and materials sector's defossilisation movement. Our collaboration with Honeywell for our Antwerp production facility marks a key step in our plans to support this transition

Vioneo plans to implement the technology at a new €1.5 billion plant in Antwerp, Belgium. This facility will use green methanol from renewable energy-based hydrogen and biomaterials and will be powered by renewable electricity.

“Vioneo’s Antwerp plant has the potential to significantly decrease greenhouse gas emissions, and help position Europe as a leader in lower emissions industrial innovation. We are delighted to be a critical technology partner to this initiative,” said Rajesh Gattupalli, president of Honeywell UOP. “Our MTO technology helps support the industry's commitment to reducing emissions and the European Union's ambitious climate goals. This technology will play a crucial role in helping transform the production of olefins, helping advance the shift away from plastics made from fossil-derived feedstocks and supporting a path to a net-zero emissions future for the region.”

Vioneo will also deploy Honeywell’s light olefins recovery process (LORP) and olefins cracking process (OCP) to ensure high-purity ethylene and propylene output while capturing and reusing byproducts. This approach minimizes waste, saves energy, reduces costs and maximizes yield.

Planned development of the Antwerp-based plant will proceed in phases, starting with a Front-End Engineering Design (FEED) in the fourth quarter of 2024 and potential Final Investment Decision (FID) in 2025. Commercial operations are anticipated to begin in 2028.

First Synthetic Eukaryotic Genome Completed

Scientists at the Macquarie University in Australia worked with an international team of scientists to achieve a major milestone in synthetic biology by completing the creation of the final chromosome in the world’s first synthetic yeast genome. This achievement represents the completion of the global Sc2.0 project to create the world’s first synthetic eukaryotic genome from Saccharomyces cerevisiae (baker’s yeast) and a new-to-nature tRNA neochromosome.

Using genome-editing techniques, including the CRISPR D-BUGS protocol, the team identified and corrected genetic errors that impacted yeast growth. These changes restored the strain’s ability to grow on glycerol, a key carbon source, under elevated temperatures.

The study “Construction and iterative redesign of synXVI a 903 kb synthetic Saccharomyces cerevisiae chromosome,” published in Nature Communications, demonstrates how engineered chromosomes can be designed, built and debugged to create more resilient organisms that could help secure supply chains for food and medicine production in the face of climate change and future pandemics, according to the researchers.

Landmark moment

“This is a landmark moment in synthetic biology,” says Sakkie Pretorius, PhD, co-chief investigator and deputy vice chancellor (research) of Macquarie University. “It is the final piece of a puzzle that has occupied synthetic biology researchers for many years now.”

“By successfully constructing and debugging the final synthetic chromosome, we’ve helped complete a powerful platform for engineering biology that could revolutionize how we produce medicines, sustainable materials, and other vital resources,” adds Distinguished Professor Ian Paulsen, PhD, director of the ARC Centre of Excellence in Synthetic Biology and co-director of the project.

The research team used specialized gene editing tools to identify and fix problems in the synthetic chromosome affecting how well the yeast could reproduce and grow under challenging conditions. They discovered that the placement of genetic markers near uncertain gene regions accidentally interfered with how essential genes were turned on and off, particularly affecting crucial processes like copper metabolism and how cells divide their genetic material.“The Sc2.0 global consortium to design and construct a synthetic genome based on the Saccharomyces cerevisiae genome commenced in 2006, comprising 16 synthetic chromosomes and a new-to-nature tRNA neochromosome,” write the investigators.

“In this paper we describe assembly and debugging of the 902,994-bp synthetic Saccharomyces cerevisiae chromosome synXVI of the Sc2.0 project. Application of the CRISPR D-BUGS protocol identified defective loci, which were modified to improve sporulation and recover wild-type like growth when grown on glycerol as a sole carbon source when grown at 37˚C. LoxPsym sites inserted downstream of dubious open reading frames impacted the 5’ UTR of genes required for optimal growth and were identified as a systematic cause of defective growth.

“Based on lessons learned from analysis of Sc2.0 defects and synXVI, an in-silico redesign of the synXVI chromosome was performed, which can be used as a blueprint for future synthetic yeast genome designs. The in-silico redesign of synXVI includes reduced PCR tag frequency, modified chunk and megachunk termini, and adjustments to allocation of loxPsym sites and TAA stop codons to dubious ORFs.

“This redesign provides a roadmap into applications of Sc2.0 strategies in non-yeast organisms.”

One of our key findings was how the positioning of genetic markers could disrupt the expression of essential genes, noted co-lead author Hugh Goold, PhD, research scientist at The NSW department of primary industries and Honorary Postdoctoral Research Fellow from Macquarie University’s School of Natural Sciences. “This discovery has important implications for future genome engineering projects, helping establish design principles that can be applied to other organisms.”

New possibilities in metabolic engineering and strain optimization

The completion of the chromosome known as synXVI allows scientists to explore new possibilities in metabolic engineering and strain optimization. The synthetic chromosome includes features that enable researchers to generate genetic diversity on demand, accelerating the development of yeasts with enhanced capabilities for biotechnology applications.

“The synthetic yeast genome represents a quantum leap in our ability to engineer biology,” according to Briardo Llorente, PhD, CSO at the Australian Genome Foundry.

The construction of such a large synthetic chromosome was only possible using the robotic instrumentation in the Australian Genome Foundry, he pointed out.

“This achievement opens up exciting possibilities for developing more efficient and sustainable biomanufacturing processes, from producing pharmaceuticals to creating new materials,” continued Llorente.

The research provides valuable insights for future synthetic biology projects, including potential applications in engineering plant and mammalian genomes, explains the research team whose new design principles for synthetic chromosomes to avoid placing potentially disruptive genetic elements near important genes will help other researchers working on synthetic chromosomes.

Today's KNOWLEDGE Share : Breaking Polymer Chains

Today's KNOWLEDGE Share

Have you ever asked yourself if breaking a plastic part (or tensile bar) always means you are breaking polymer chains ?

It is not a trivial question and it is actually quite an important aspect to address if we want to better understand a polymer performance.

As it turns out it has a lot to do with the polymer chain entanglement density of the polymer of interest (and the temperature).

In a loosely entangled polymer, like Polystyrene, the lower ability to delocalize stress inside the network will allow an easier reach of the carbon-carbon bond strength limit, allowing thus significant chain scission when breaking a PS sample.

On the other side, highly entangled polymers like PC or PSU/PES/PPSU will spread the stress around the much denser entangled network, making carbon-carbon bonds way more unlikely to fail. The result is that failure will be dominated by disentanglement.

This has been proven by observing the significant appearance of free radicals (testifying chain scissions) on the PS fracture surface, contrary to the lack of free radicals for a PC fractured sample.

Of course, at very low temperatures, plasticity is almost totally suppressed, leaving chain scission as the only failure mechanism for all polymers, regardless of their entanglement density.

The Physics at play is not so different from what we observe in GF filled grades. Classical short GF (150-250 micron long) are too short to develop a stress higher than the glass stress at break, so fibers will be pulled out when breaking a sample.

LGF (long glass fibers, say longer than 1 mm) will typically break because the fibers are beyond the “critical length”, allowing the maximum stress in the fiber to reach the strength of glass.

Researchers Develop Bioinspired Adhesive for Fetal Surgery & Repairs:

For over 20 years, Professor Phillip Messersmith from Berkeley has drawn inspiration from nature to develop innovative resins and adhesives for medical and industrial applications. This approach, which he refers to as bioinspiration, involves studying natural molecules to create synthetic counterparts in the lab.

Manipulate Lipoic Acid Chemistry to Improve Stability:

Messersmith’s early work focused on the "glue proteins" secreted by mussels to attach to surfaces, and his research has expanded to include other natural molecules, such as lipoic acid. This molecule, produced in the human body to support cell respiration and energy production, also serves as a monomer for creating larger polymers.

According to Messersmith, lipoic acid’s inherent flexibility makes it a versatile material. However, Subhajit Pal, a postdoctoral researcher in his lab, discovered, that the polymerized form of lipoic acid tends to degrade when exposed to water. This challenge has motivated ongoing research into improving its stability and broadening its potential applications.

Water-activated Superglue:

By modifying 7 to 15 percent of lipoic acid monomers with the molecule N-hydroxysuccinimide, Pal created a stable solution that would form a superglue on contact with water. That superglue could be applied during surgery to incisions in the amniotic sac, the layers of tissue surrounding a fetus in the uterus.

Starting small, Messersmith’s team applied the new polymer adhesive via a “patch” to the fetal membranes of lab mice, into which they poked holes. All of the mice fetuses in patched uteruses survived without issue while all of the “control” mice died.

The next step is to try the polymer adhesive on a larger animal like a sheep. If that works, it’s on to humans. An effective superglue holds promise for pregnant women in two situations: one, when the fetal membranes rupture spontaneously in the third trimester and need to be repaired; and two, when a surgeon needs to enter the uterus to perform a procedure on the fetus and then patch the surgical incision.

“That’s why we do this, to eventually apply it to humans,” Messersmith says.

Today's KNOWLEDGE Share:New Adhesive from Kiilto

Today's KNOWLEDGE Share

A new adhesive line with further improved quality and efficiency in bonding of load-bearing wooden structures

In the production of wooden structures, Kiilto Pro SW, a new line of one-component polyurethane adhesives, can boost the bonding process by up to 30%. The adhesives meet the requirements of EN 15425:2023 I 90 GP 0.3 w (adhesive type I). The different stages involved in the production of engineered wood have been extensively studied in developing the adhesive. In addition to improved production efficiency, this attention to detail can be seen in the excellent foaming properties of the adhesive. These properties reduce the need for adhesive in production.

Wood construction is becoming increasingly popular, as it contributes to achieving the goal of carbon neutrality. Wood is also a warm, safe and aesthetic construction material. Cross-laminated timber, or CLT, has provided the industry with new opportunities, and log construction has once again become popular.

Kiilto has developed a new adhesive line, offering a wide range of technical solutions for the engineered wood industry. The Kiilto Pro SW line is suitable for applications requiring strength and quality that can withstand decades of use. According to Business Development Manager Juha Rinne of Kiilto, the product’s applications include not only cross laminated timber but also roof trusses, glulam beams, log construction and structural finger jointing.

Optimal ratio between open and pressing time

As RDI Manager Jussi Hänninen of Kiilto points out, the required open time of adhesive vary, depending on the number of layers that the CLT element is to be made up of – for example, three, five or seven.

“The Kiilto Pro SW line includes options with an optimal ratio between the open and pressing times. This way, the customer can choose the adhesive that is best suited for their factory and production.”

Often, the optimal solution for the engineered wood industry is one with a long open time but the shortest possible pressing time.

“Usually, when the pressing time is divided by the open time, the resulting coefficient is 2.5. However, with the Kiilto Pro SW line, in standard conditions the coefficient can be as low as 1.5,” says Hänninen.

Rinne calculates that optimising the ratio between the open time and pressing time can help increase the efficiency of the bonding process by up to 30%.

“In other words, productivity can also be improved by simply changing the adhesive, without the need to invest in a new press, for example.”

 

Less adhesive – without compromising on quality

“The adhesive spreads well and penetrates the wood during the pressing phase. A high-quality bonding result can be achieved with less adhesive, which reduces production costs. Material efficiency also contributes to environmental friendliness,” Rinne points out.

The product is highly shear-thinning, meaning its viscosity is high when stationary and decreases during movement.

Bio-based option on the way

Wood construction is already a good option for achieving a lower carbon footprint in construction. If the carbon footprint of the end products is to be further reduced, there is also an option for that.”

“Kiilto will also launch a product with identical technical properties but made of partly bio-based components instead of fossil ones. The proportion of bio-based materials can be up to 25%,” says Hänninen.
