Puraffinity' Press

October, 2024 Puraffinity, which develops precision technologies to remove toxic “forever chemicals” perfluoroalkyl and polyfluoroalkyl substances (PFAS) from water, has appointed Jessica Middlemiss as Chief Technology Officer. Jessica joins from Matter, an environmentally focussed startup which develops technology to remove micro-scale pollution from water. Prior to Matter, Jesscia was Head of Plastics Technology at Sartorius and spent ten years at Dyson including two years as Head of Operations for The Dyson Institute – Dyson’s in-house undergraduate degree-apprenticeship programme. “Jessica has a really broad technical and business network across both industry and academia which is valuable to us,” said Puraffinity co-founder Henrik Hagemann. “Jessica brings relevant start-up experience from her time at Matter, leading a large team of scientists at Sartorius and held a variety of engineering and management positions at Dyson. We are delighted to have her join us.” “I believe I have the combination of technical understanding and people skills which will help Puraffinity flourish,” said Jessica. “I have built my career on an ability to bring together exceptional technical people to work on clear and targeted challenges as a team. I know how to get people motivated and focussed on a common goal that delivers commercially for the organisation.” Jessica has a Masters in materials science and engineering from Imperial College London and is a Fellow of the Institute of Materials Minerals and Mining (IOM3).

Puraffinity, a start-up developing precision technologies which remove toxic “forever chemicals” perfluoroalkyl and polyfluoroalkyl substances (PFAS) from water, has announced ambitious plans to scale, following the appointment of Vincent Caillaud as its new CEO and securing £6.73 million in new investment from BGF. Mr Caillaud brings exceptional industry experience, with more than 20 years working in the water sector. He was previously CEO of Veolia Water Technologies & Solutions, a global water technology business unit within the world’s largest water, energy and waste management company, Veolia. The appointment of Vincent Caillaud as Chief Executive Officer to boost market access for the technology, will allow Puraffinity’s founder Henrik Hagemann to focus on furthering the company’s market-leading technological advantage as Chief Product and Innovation Officer. BGF’s investment completes Puraffinity’s £16.93 million Series A funding round, following existing funding from Octopus Ventures, HG Ventures, Kindred Capital, and Verve Ventures, as well as materials science sector specialist fund Universal Materials Incubator Co (UMI). The funding will enable Puraffinity to scale up production of its patented, PFAS-capturing material, “Puratech ®”, to meet exceptionally strong and growing demand across multiple sectors. It will also support the company’s work developing fresh commercial applications that use Puraffinity’s patented materials. Founded in 2015 by Henrik Hagemann & Gabi Santosa and spun out of Imperial College London, Puraffinity provides a differentiated solution to the world’s ever-growing PFAS problem as its technology consistently and reliably removes PFAS from water, in a much more cost-effective manner compared with conventional treatments. Puraffinity’s precision technologies place it at the forefront of the fight against PFAS, which have been linked to multiple health issues, including cancer. Developed in the 1940s, PFAS’ molecular make-up makes them resistant to water, grease and oil, meaning they have multiple industrial uses. However, these same qualities make them hard to destroy, hence the name “forever chemicals”, and according to the National Institute of Environmental Health Sciences, they have entered water supplies worldwide, with an estimated 97% of people having PFAS in their bodies. International regulators are examining bans or limits on the amount of PFAS drinking water can contain in an attempt to tackle the estimated €16 trillion annual cost of environmental remediation and healthcare costs. Puratech, the breakthrough adsorbent media that Puraffinity has developed, can be applied across use cases as it features a customisable plug-in solution that fits into any existing water treatment system. Puratech can also be tailored to capture specific PFAS compounds, ensuring that global users can meet the regulatory standards of different markets. The high-performing material also adopts a green chemistry technology which, according to Systemiq 2022, results in 60% less carbon emissions in its manufacturing than existing petroleum-based products. Henrik Hagemann, founder and Chief Product & Innovation Officer at Puraffinity, said: “Attracting such a respected water industry figure as Vincent, alongside nvestment from BGF underlines not only the progress Puraffinity has already made, but the incredible potential of the business. The new management structure will allow me to focus on accelerating our existing technologies and developing new product roadmaps, confident that Puraffinity’s business development is assured with Vincent as CEO.” Vincent Caillaud, CEO of Puraffinity, said: “At Puraffinity, we are delighted to join BGF’s growing network of climate tech start-ups as the company continues on its mission of providing PFAS-safe water to the world. With BGF’s expertise in helping start-ups in breakthrough technologies achieve transformational growth, we look forward to meaningfully expanding our commercial capability and extending the global reach of our patented PFAS-removal solutions.” Luke Rajah, investor at BGF, said: “Puraffinity is well-positioned to fulfil its vision of bringing PFAS-safe water to one billion people by 2030. BGF is thrilled to work with Puraffinity as it enters a new phase of rapid, global growth, taking a meaningful step towards enhancing water safety. BGF has developed a strong reputation for identifying and providing early-stage support for companies creating technologies which not only have huge potential but offer huge societal benefits.”

Puraffinity wins Morgan Stanley sustainable solutions award $250,000 prize and a year-long partnership to help growth and scale up

With US$13.9m raised in Series A funding, this water treatment company which focuses on per- and polyfluoroalkyl substances (PFAS) aims to eliminate these ‘forever chemical’ contaminants in both industrial and domestic settings by scaling its technology and expanding its manufacturing investment, according to Puraffinity CEO Henrik Hagemann.

The Royal Society of Chemistry is calling on the UK Government to overhaul its drinking water standards, after new analysis reveals more than a third of water courses tested in England and Wales contain medium or high-risk levels of PFAS, more commonly known as forever chemicals.

Puraffinity, which develops precision technology for the removal of PFAS ‘forever chemicals’ across multiple water treatment applications, has raised $13.9m in Series A funding. The round was led by Octopus Ventures, with participation from existing investors Kindred Capital, HG Ventures, Verve Ventures and Acequia Capital. Materials science sector specialist fund Universal Materials Incubator Co (UMI) also joined the round.

HG Ventures recently increased its investment in Puraffinity, participating in the London-based startup’s $13.9M Series A funding round. Puraffinity is focused on combating the ‘forever chemicals’ found in water; here, Co-founder and CEO Henrik Hagemann shares his insights from participating in this year’s United Nations Water Conference, and his ambitions for the future.
