Meet the woman tackling a neglected environmental challenge by transforming urine into fertiliser

Meet the woman tackling a neglected environmental challenge by transforming urine into fertiliser

Farmer Connect and SCANTRUST join iforces

When Nadège de Chambrier decided to study environmental engineering she didn’t think she’d end up talking about urine all day long. Her startup has created a unique solution that relates to two resources that are critical to effective food systems: water and fertiliser. And now she’s gearing up to set up three treatment systems in France, Switzerland and Germany as part of a joint programme with the European Space agency.

Tell us a bit about you and your VunaNexus story.

My name is Nadège de Chambrier and I studied Environmental Engineering at EPFL and ETH Zurich, specialising in wastewater treatment. About 2 years ago I joined forces with my brother David and two other co-founders Kai Udert and Bastian Etter and together we founded VunaNexus AG. 

Kai and Bastian had previously been researching how to recycle the nutrients contained in urine for around 15 years with the help of the Eawag (the water research institute of the ETH Domain) and the Bill and Melinda Gates Foundation, so we had a great deal of knowledge and practical research to draw on. 

I’ve been working on developing and implementing this urine treatment technology for 5 years now. During the first lockdown, David, who had a background in business, started helping us to build a business case out of it. Then we decided to go ahead and found a company focused on selling the technology. 

Describe what your company does in a single sentence.

VunaNexus uses a patented technology to transform human and livestock urine into two valuable products: an authorised NPK fertiliser, Aurin,  that is free of all dangerous pollutants and water that can be reused, while drastically reducing ammonia emissions and water pollution.

What gets you out of bed in the morning? 

CO₂ has become “the” topic when it comes to sustainability, but there are many other issues that impact our ecosystem more than global warming – and of which most people are not aware.  

If we look at the planetary boundaries, the cycles of nitrogen and phosphorus have been radically changed by humans and this has a devastating impact on the environment. Raising awareness of the multiple problems linked to wastewater and sanitation, and recycling these precious nutrients, as well as trying to change the linear system we’re currently working within thanks to great technology – this is what gets me up in the morning.  

It’s not always easy to talk about pee and poo, but people are actually really interested in better understanding the challenges associated with this topic, and appreciate that everyone can contribute in their own way to closing the nutrient cycle.

What key milestones have you hit so far?

So far, we’ve bootstrapped the business. But we recently got accepted into a business support program run by the European Space Agency. This will help us install a treatment system at the European Space Agency headquarters in Paris, one at BlueFactory in Fribourg and one in the region of Berlin in the context of the projekt Zirkulierbar. 

At the moment, we don’t think that external investment is the right choice to accelerate the adoption of the technology, as we need to make sure the market can absorb the fertiliser we will produce. Over the next two years we aim to prove that our model can scale, that we can resell fertiliser locally and that these treatment plants are financially viable.

What projects are you and your team working on at the moment? 

We have an ongoing project with Innosuisse that aims to test our technology on animal urine on a larger scale. We have a test reactor that can process up to 3000 litres of urine a day. When it comes to reducing ammonia emissions, this could be a huge step for many farms all over the world. It could also help to tackle micropollutants including antibiotics and other drugs before spreading the manure on fields. 

How do you collaborate and support others in the ecosystem? 

We’re currently new to the ecosystem so we haven’t had the chance to support other Valley partners yet. But we have lots of knowledge and a strong network around wastewater and sustainable fertilisers that we would be more than happy to share! 

What support could the Valley community offer to further your work?

We’re looking for contacts that would be interested in experimenting with a novel fertiliser, and would love to connect with anyone open to collaborating around wastewater recycling more generally. Please get in touch! 

Tell us something we don’t know about your company.

Vuna started as a project in South Africa to tackle two connecting issues that affected decentralised communities: how to treat their wastewater and how to find an economical fertiliser for their fields. The word Vuna means harvest in isiZulu. First there was Vuna GmbH, a company specialised in decentralised sanitation alternatives, and then we created VunaNexus, a sister company.

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.

Swiss plant-based startup Yumame Foods closes pre-seed funding round

Swiss plant-based startup Yumame Foods closes pre-seed funding round

Image of the Yumane team

Yumame Foods AG, a Swiss startup that develops and produces vegan products, has announced the closure of its first funding round, raised in participation with industry partners. The funding will allow the plant-based startup to scale up the production of their products and prepare for market entry in Switzerland.

Minimally processed and locally produced alternatives

Founded in 2021, Yumame Foods develops and produces vegan alternatives to meat. Unlike meat analogues that aim to mimic the real thing, Yumame’s plant-based products have their own unique and delicious taste, are minimally processed and locally produced.

Driven by the need to improve environmental sustainability, health, and animal welfare, consumers worldwide are on the hunt for vegan meat substitutes like Yumame’s. Several industry reports predict that the global market for meat alternatives will experience strong growth in the coming years and reach a multi-billion dollar value by 2030. But despite the momentum in the category, some plant-based meat analogues struggle to attract and maintain consumers, due to concerns about artificial flavours or the lack of a  natural mouthfeel and texture.

Blending fungi and fermentation

Yumame Foods is on a mission to develop healthy, tasty and sustainable foods that fundamentally overcome these limitations. The company blends fungi and fermentation to create vegan alternatives to meat: instead of aiming to simulate animal products, Yumame’s products have their own unique taste and texture, and undergo minimal processing. They are easily cooked with a variety of methods and can be produced in any location using local ingredients. This innovative approach lies in both the product formulation and the production process. The proprietary formulations have been developed in collaboration with chefs and fermentation specialists.

So far, the company has received financial support from Innosuisse and the startup program VentureKick. The new investment round was supported by Italian food company Molino Quaglia S.p.A. and Swiss company Juna Holding A.G.

Next steps

The funds will accelerate the industrialization of Yumame’s consumer products ahead of their launch on the Swiss market.

Founder and CEO Eliana Zamprogna Rosenfeld says a large proportion of the money will go towards further optimizing the company’s production capacity, as well as the product’s shelf life and nutrient profile. Yumame will also develop further recipes to expand its range. This will happen alongside investment in the communication of the concept and brand, and consumer testing of the product ahead of launch.  

“We’re thrilled to have closed this investment round with the support of leading investors, who have profound knowledge of the food industry and business development,” said Eliana Zamprogna Rosenfeld. “This achievement is a sign of the confidence in our approach. The funds will enable us to better address consumers’ need for tasty, simple and local foods that are nutritious and convenient to use in place of meat.”

“We are really pleased to support Yumame Foods in this important step into the domestic market and to prove that food can be made fundamentally more sustainable by using local resources and efficient production methods,” said Philipp Balmer, CEO of Juna Holding AG. “It is also a key milestone in terms of the future internationalization of the products and extension into other food categories,” added Lucio Quaglia, CEO of Molino Quaglia S.p.A.

About Yumame Foods

Founded in 2021 and based in Küsnacht in the canton of Zurich, Yumame Foods produces delicious, healthy and sustainable food based on fungi and fermentation. Their aim is to provide consumers with a delicious center-of–the-plate option as an alternative to meat and highly processed meat alternatives.
