EPFL’s Prof. Jeremy Luterbacher on turning plants into plastic

Mirai foods burger

Prof. Jeremy Luterbacher from EPFL’s Laboratory of Sustainable and Catalytic Processing has developed a way to turn plant by-products into materials that could serve as an alternative to some types of plastic.

Researchers at EPFL found that some types of sugar are particularly well-suited to functionalization reactions. One sugar – xylose – is ideal, and plant residue contains a lot of it – up to 20–30%. This means that by using functionalization reactions, they can produce 300 grams of bioplastic out of one kilogram of corn cobs.

“It must be because I’m a chemist, but I find functionalization reactions fascinating. They involve adding a functional group to a chemical compound in order to give it additional properties, but without changing its base structure. These reactions are fairly easy to perform and consume little energy and other resources. You don’t have to break down complicated chains.”, commented Jeremy Luterbacher from EPFL’s Laboratory of Sustainable and Catalytic Processing.

A wide range of applications

The process for producing bioplastic from xylose is simple to carry out and it employs materials that are readily available. It doesn’t alter the base xylose molecules, meaning that as the bioplastic degrades, it simply releases the sugar – which is harmless to the environment.

The resulting material is both tough and heat-resistant and could be used in a variety of application. It can be manufactured as a film, as thread for making fabric or fishing nets, or rolled up in spools for use with 3D printers. It can also make polyesters and polyamides such as nylon with excellent properties, sometimes even better than those made from petroleum-based products. Food packaging could be another application, but the material still needs to go through various certification processes.

Bringing the bioplastic to market

To bring the bioplastic to market, EPFL need to be able to manufacture it at a competitive cost. This would mean around half the price of existing bioplastics and on par with petroleum-based plastics. But their estimates show that this is possible. 

“The leaf I’m showing here illustrates the vast potential for our bioplastic. You can see that it allows for extreme precision for producing objects of all kinds. We’re right at the beginning of our journey and we still have a lot of work ahead of us, both in the research lab and with Bloom Biorenewables, a startup we founded to market the technology coming out of our lab. But that just makes our work all the more exciting!” concluded Jeremy.

Nestlé and EPFL collaborate on biobased food packaging with Project BIOPACK

Nestlé and EPFL collaborate on biobased food packaging with Project BIOPACK

Mirai foods burger

In our first Co-create & Innovate case study, we find out more about Project BIOPACK – a collaborative partnership between EPFL’s Laboratory for Processing of Advanced Composites, Algaltek, an EPFL spin-off and Nestlé Research.

The challenge

Rethinking the way that packaging materials are produced is key to a sustainable, waste-free future. But some packaging elements are still not recyclable, or are not sorted or collected correctly. This means that they’re still sent to landfill or end up polluting our oceans.

The opportunity

In 2019, Nestlé opened a dedicated Institute of Packaging Sciences in their Research Center in Lausanne to enable them to play a leading role in finding alternatives to single use plastic. As a member of the Integrative Food and Nutrition Center, the Nestlé team was able to connect with EPFL’s Laboratory for Processing of Advanced Composites and the GR-LUD, an algae specialized laboratory at EPFL. This gave them access to specific scientific capabilities that could accelerate their work – and Project BIOPACK was born.

The collaboration would focus on creating life-cycle engineered, bio-based food packaging solutions that would minimise their environmental impact. But that wasn’t all. The project would also consider how these materials would be treated at the end of their lives – something that is key for a sustainable waste-free future. The project aimed to contribute to both organisations’ visions of a zero-waste food sector.

The collaboration

The partners decided that they wanted to adopt a “holistic life-cycle” perspective. This meant moving away from non-renewable and non-recyclable resources and instead concentrating on cost-efficient bio-based materials with reduced environmental footprints.

These materials are typically based on microfibrillated cellulose – MFC, a new form of engineered cellulose – that’s made from renewable biomass sources like microalgae and wood. The materials are designed to be compatible with existing end-of-life valorisation methods.

Reflections & next steps

The collaboration allows both partners to play to their respective strengths: EPFL focuses on the production and disposal of bio-based materials and their characterization, while Nestlé contributes with Life Cycle Assessment studies that take the entire life cycle into consideration. Nestlé also provides inputs for specific case studies related to target markets and product types for which the packaging materials will be designed.

Both stakeholders plan to continue their collaboration to develop a comprehensive understanding of the entire packaging life cycle and their performance in relation to relevant sustainability criteria. 

A few words from the partners

Commenting on the collaboration, Yves Leterrier, senior scientist at EPFL’s Materials Science Institute, said: “Sustainable packaging does not exist, but an approach based on a sustainable product life cycle can help to optimise the net system impact of new packaging solutions.”

Lise Zeboudj, Department Manager, Packaging Materials at the Nestlé Institute of Packaging Sciences, said: “The development of new high performing, sustainable alternative packaging materials is a key part of our waste-free strategy. This requires a fundamental understanding of material structures and performance – which is why we are collaborating with our partners at EPFL.”

Eya Damergi Nicodeme, Posdoc researcher and co-founder of Algaltek added: “We, the research team at GR-LUD led by Prof. Christian Ludwig, have developed a unique culturing technique for algae that yields pure, high-yield microfibrillated cellulose. With a filed patent and a partnership with Nestlé, we aiming to scale this technology and explore the limitless possibilities this algae offers.”

Fribourg’s agri-food strategy proves to be an effective catalyst

Fribourg’s agri-food strategy proves to be an effective catalyst

Image of the Yumane team

Three Fribourg State Councillors recently presented the early results of the Canton’s economic development strategy for the agri-food sector. Over the last year, an interdisciplinary team has developed a project for each of the Strategy’s three flagship programmes. The results now are set to pave the way for new, sustainable economic activities in this booming sector.

Three flagship projects

Over the last year, Valley partner Cluster Food & Nutrition has been working to deliver Fribourg’s new strategy for the development of its agri-food sector, powered by a CHF 1 million budget. Throughout 2022, three interdisciplinary teams worked in close collaboration with leading local and regional companies to develop a project relating to each of the strategy’s three priority areas:

Project 1: Optimized nitrogen fertilization 
This project focused on optimizing fertilizer quantities by using data analysis to increase yields and reduce environmental impact. Several methods were tested and by using drones equipped with multispectral cameras, the project was able to gather a large amount of data that confirms that these methods were more efficient than traditional approaches.

Project 2: Proteins and additives for a circular economy
This project aimed to develop circular and sustainable models by finding new ways to use local by-products, in particular whey. Project partners developed a technique that enables the production of high value-added, nutritionally beneficial ingredients.

Project 3: Food & Farm Living Lab 
This project was designed to actively enable consumers and citizens to drive a more efficient and sustainable food system. Over 500 individuals took part in seven consumer tests conducted throughout 2022 in collaboration with regional companies. This led to the development of targeted methodological tools to rapidly test new products, concepts, or business models. 

Linking practical knowledge with scientific expertise

Commenting on the projects, the President of the Cantonal Government and Minister of Institutions, Agriculture and Forestry, Mr. Didier Castella, stated: “The development of the Grangeneuve-Posieux campus and the AgriCo site in St-Aubin make it possible for Fribourg to support the entire Swiss agri-food sector both in the area of production, as well as in research and training.”

Minister of Education and Cultural Affairs, Ms. Sylvie Bonvin-Sansonnens added: “This strategy provides a real opportunity to link practical knowledge with the expertise of scientific research in order to create a more sustainable and efficient agri-food sector in the future,” while the Minister of Economic Affairs and Vocational Training, Mr. Olivier Curty, remarked that the initial results “are very encouraging and show that thanks to the investments made in recent years, the Canton of Fribourg now has both the tools and the skills needed to become the Swiss leader in this sector.”

How Givaudan’s Sense It® taste language translates science into emotions

How Givaudan’s Sense It® taste language translates science into emotions

Givaudan

With over 400 descriptors and digitalisation plans, the sensory language is building as ever-clearer window into the consumer mind.

Sense It®, a proprietary taste language created by Givaudan, is celebrating its 30th anniversary. First developed in 1993, it has become a universal and standardised language used around the world for food experience characterisation, differentiation, and product innovation.

Sense It® has grown enormously since its inception, with Givaudan regularly adding new descriptors to the language. What began as a local tool for flavour characterisation has been transformed into a robust universal language with descriptors for flavour, taste and mouthfeel.  As the language has grown, so has its ability to describe up-and-coming categories, such as plant-based meat. For example, the introduction of a mouthfeel language for solid applications was recently rolled out, enabling manufacturers to better understand how to modulate dry, astringent and juiciness characteristics in plant-based products. 

Fabio Campanile, Valley Executive Committee member and Global Head of Science & Technology Taste & Wellbeing, explains, “Consumers know if they like or do not like a product, but have difficulty explaining why. Sense It® helps bridge the gap between what consumers perceive and what they are able to express. Over the years the language has been expanded into new, important categories and so it continues to be very valuable in helping guide our customers with their product creation.”

A strength of the Sense It® language is that it allows usage in virtual environments, when alternatives to in-person consumer testing are needed. Trained panels at Givaudan were able to use Sense It® along with their proprietary holistic profiling method to provide customers with highly accurate information on consumer perception without going to consumers. 

Looking to the future, digitisation will play a key role in simplifying the language’s increasing complexity and creating a seamless experience for users. Fabio remarked, “We’re creating a new set of digital tools that will help the user put their sensory perception of a product, such as a plant-based burger, into descriptive words that convey the full experience, including mouthfeel, colour and taste.”

While Sense It® will greatly benefit from this digitisation, it’s also playing a pivotal role in helping AI tools and digital tools become more effective. By translating consumer perception into language, Sense It® provides a rich vocabulary with which we can digitally communicate about the senses, supporting and enabling our next generation of language-based AI applications.

Nestlé inaugurates new research institute aimed at supporting sustainable food systems

Nestlé inaugurates new research institute aimed at supporting sustainable food systems

Image of the Yumane team

Nestlé has officially inaugurated the Institute of Agricultural Sciences to help advance sustainable food systems by delivering science-based solutions in agriculture.

Speaking at the inauguration, Paul Bulcke, Nestlé Chairman, said: “We have nurtured direct relationships with generations of farmers around the world. To continue providing people with tasty, nutritious and affordable foods, we need to transition together to a more sustainable food system. The new institute will strengthen our expertise and use our global network to support farming communities and protect our planet.”

With global food systems under pressure, there is an urgent need to accelerate new approaches that ensure a sustainable food supply for a growing world population while contributing to farmer livelihoods.

At the new institute, Nestlé experts screen and develop solutions in key focus areas such as plant science, agricultural systems and dairy livestock.

It builds on the company’s existing plant science expertise in coffee and cocoa. Over many years, Nestlé plant scientists have been contributing to Nestlé’s sustainable cocoa and coffee sourcing plans – the Nestlé Cocoa Plan and Nescafé Plan (pdf, 9Mb) – including the recent discovery of more disease and drought-resistant coffee varieties.

Nestlé is now strengthening this expertise and expanding it to further crops, including pulses and grains. The institute is also working with farmers to trial regenerative agriculture practices to improve soil health and encourage biodiversity. In addition, experts explore novel approaches in dairy farming that have potential to reduce greenhouse gas emissions in the areas of cow feed and manure management.

Jeroen Dijkman, Head of Nestlé Institute of Agricultural Sciences, said: “Our goal is to identify the most promising solutions to promote the production of nutritious raw materials while minimizing their environmental impact. We take a holistic approach and look at several factors including impact on yield, carbon footprint, food safety and cost, as well as the viability of scale-up.”

As part of Nestlé’s global R&D network, the institute collaborates closely with external partners including farmers, universities, research organizations, startups and industry partners to assess and develop science-based solutions. The new institute reaffirms the company’s commitment to strengthening Switzerland’s unique innovation ecosystem.

Speaking at the official opening, Valérie Dittli, State Councilor of the Swiss Canton of Vaud, said: “The new institute is strengthening the Canton of Vaud as a center of excellence for research and education in agriculture and nutrition. It also contributes to the efforts that are underway to support farmers in the face of climate change. Agriculture is at the core of quality nutrition and in the Canton of Vaud we can count on an innovative ecosystem that brings together partners including agricultural professionals, schools for higher education and private research centers such as the one from Nestlé.”

In addition to its new facilities at Nestlé Research in Switzerland, the institute incorporates an existing plant science research unit in France, and farms based in Ecuador, Côte d’Ivoire and Thailand, as well as partnerships with research farms.
