  1. The £200 Billion Problem That Algae Might Solve | HutanBio Founders

    The £200 Billion Problem That Algae Might Solve | HutanBio Founders

    Six years of continuous algae cultivation. Zero crop failures. A world first. In this episode of the Sustainable Times Podcast, we sit down with HutanBio CEO Manshu Agarwal and Founder & Chief Scientific Officer Dr John Archer — the Cambridge-based biotech quietly building one of the most credible answers to the hard-to-abate fuel problem. Where ExxonMobil walked away from algae biofuel and competitors like Viridos spent years on genetically-modified strains, HutanBio took a fundamentally different path. Their proprietary marine microalgae strain, Sphaerica — discovered through a multi-year bioprospecting programme in extreme tropical marine habitats — delivers up to 10x the yield of previous algae and oil crops. No genetic modification. No fresh water. No competition with arable land. Grown on seawater, in desert environments, using only CO₂ and sunlight. The result: HBx Bio Oil — a net-negative carbon biofuel designed for the sectors fossil fuels still own. Maritime. Aviation. Heavy land transport. What we cover: — The two-decade scientific journey from Cambridge and KAUST to commercial deployment — Why the algae biofuel market has failed before, and what HutanBio is doing differently — The Sphaerica discovery and what makes it commercially defensible — Building a high-yield, modular production platform engineered for desert deployment — The £2.25m Clean Growth Fund investment and what scaling looks like next — The IMO 2030 emissions mandate and why maritime is the beachhead market — What investors should understand about the hard-to-abate fuel opportunity in 2026 — GUESTS Manshu Agarwal — CEO, HutanBio linkedin.com/in/manshuagarwal Dr John Archer — Founder & Chief Scientific Officer, HutanBio linkedin.com/in/john-archer-b551569 Harvey Knight — CEO & Founder, Sustainable Group linkedin.com/in/harvey-knight-38aa91a9 — ABOUT HUTANBIO Founded in 2019 by Dr John Archer (Cambridge), Dr Noor Azlin Mokhtar, and Suhaiza Jamhor, HutanBio is a UK-based climate biotech developing scalable, net-negative carbon biofuels from proprietary marine microalgae.

    Sustainable Times Investor Series — Robin Grenfell Cowan: What Really Drives Early-Stage Investment Decisions

    Host: Stuart Hall, Managing Director, Sustainable Media GroupGuest: Robin Grenfell Cowan, High-Net-Worth Investor Episode Overview In the first episode of the Sustainable Times Investor Series, Stuart sits down with HNW investor Robin Grenfell Cowan to explore how early-stage investment decisions are really made in private markets. Robin has backed multiple pre-seed and seed-stage companies and brings a candid view on founders, deal flow, due diligence and sustainability-led innovation. This episode focuses on what makes an opportunity stand out, what makes investors walk away, and how honesty, humility and long-term thinking shape investment outcomes. • Why people matter more than anything • Due diligence beyond the numbers • The biggest red flags • Pitch decks: what works and what doesn’t • Why he doesn’t require revenue • EIS/SEIS and the awareness gap • Where the next wave of innovation will come from • Advice for founders This conversation cuts through the noise. It’s a grounded look at how investors actually think, something both founders and early-stage investors will find useful as the market resets for 2026.

    Ep.35 Claire Tange, Joanna Invests

    “When you change who invests, you change what gets built.” This week on Profit Meets Purpose Claire Tange, Co-Founder of Joanna Invests, discusses the community of female investors and founders she has built since 2022. Claire saw the problem of gender inequality first-hand while working in both investment banking and startups. “We need to be smarter with our money,” she says. “Once we have it, we need to invest.” Even for willing investors, Claire says, deal flow is hard to access without an established network and harder still when focusing on female founders. Since the first deal in 2022, into tech platform ‘We Are Eves', described as TripAdvisor for beauty products, Joanna Invests has backed ten female-founded companies across sustainability, fintech, health, and sport. Joanna Invests has placed great emphasis on the value of community. Before investment, founders host webinars with potential investors. Afterwards, Joanna Invests arranges small “investor dinners” at the founders’ offices, where women meet the people behind the products they’re backing. “Those evenings are incredibly energising,” she says. “Women ask different questions; they're more interested in understanding how the business really works, not just what the numbers say”. Ultimately, Claire wants Joanna Invests to complete the loop by funding female founders who later become investors themselves. “That’s the goal,” she says. “You invest in them, they build something successful, they exit and then they come back and invest in the next generation.” Listen to the episode for the full conversation with Claire and learn how Joanna Invests is empowering a generation of female investors.

    Ep.34 Karan Chopra, Kevin Vranes, Earthena AI and Worldly

    "Resilience through intelligence." On this week’s Profit Meets Purpose, Sustainable Times explores how artificial intelligence is reshaping business resilience. Daisy Moll speaks with Karan Chopra, Co-founder of Earthena AI, and Kevin Vranes, Chief Product Officer at Worldly, about how AI is helping companies manage risk, improve efficiency, and uncover opportunity in an age defined by climate uncertainty. Founded in 2023, Earthena AI offers “decision intelligence for resilience,” an AI-reasoning engine that helps organisations turn complexity into action - translating data into insight and insight into strategy. Their partnership with Worldly, a leader in supply-chain intelligence, fuses global datasets with proprietary supplier data to identify risks, model returns, and surface investment opportunities with unprecedented precision. For investors and founders alike, the conversation reveals how AI can accelerate transformation, from decarbonisation to supply-chain optimisation, turning sustainability from a compliance exercise into a driver of competitive advantage. Chopra and Vranes also reflect on the responsibility that comes with innovation, and how intent, not technology, determines impact.

    Ep.33 TJ Mitchell, ARDA Biomaterials

    “Imagine a Guinness X Gucci leather jacket!” This week on Profit Meets Purpose, TJ Mitchell, Co-founder and Chief Technology Officer of ARDA Biomaterials, explains how they are turning beer waste into a scalable, plastic-free leather alternative. After completing a PhD in supramolecular chemistry at Oxford, Mitchell joined the startup accelerator Entrepreneur First, where he met his co-founder Brett Cotten.  Leveraging Mitchell’s chemistry expertise, ARDA transforms proteins from waste grain from breweries into a material as strong and flexible as leather that is bio-based and plastic-free. From making two-litre samples in Mitchell’s kitchen to partnering with Beavertown Brewery on a limited run of cardholders, ARDA has scaled fast. The company raised £1.1m in seed funding led by Clean Growth Fund and secured an £800k Innovate UK grant, followed by a £4m round led by Oyster Bay, early investors in Oatly. Now part of AB InBev’s 100+ Accelerator, ARDA is running a paid pilot using waste grain from major global beer brands. The company envisions decentralised facilities co-located with breweries, turning local waste into local materials. Arda’s goal is to reach price parity with plastic leather, then undercut animal leather which would achieve circularity at industrial scale. “The first half of our process looks like a brewery, the second like a plastics plant,” he says. “That means we can scale fast without reinventing the system.” Website: https://arda.bio/ ST Website: www.sustainabletimes.co.uk Contact: daisy.moll@sustainabletimes.co.uk

    Ep.32 Christophe Williams, Naked Energy

    “I call it the Cinderella of solar” This week on Profit Meets Purpose, Daisy Moll sits down with Christophe Williams, Founder and CEO of Naked Energy, to explore why solar thermal is the forgotten Cinderella in the clean energy story… Williams doesn’t come from the typical engineering mould. Before launching his clean tech venture, he led award-winning ad campaigns for Sony, Microsoft and BMW — even earning a Guinness World Record for a Toshiba commercial. But a chance conversation in 2009 opened his eyes to “the big heat problem” the fact that half the world’s energy goes into producing heat and led to the creation of Naked Energy. Today, Naked Energy is redefining solar with Virtu, a hybrid technology that combines photovoltaic and thermal technology to generate both electricity and heat,  delivering up to four times the carbon savings of standard panels. With 24 patents, TÜV certification, and £30 million raised, the company has already completed more than 150 projects across 10 countries, from luxury hotels to the British Library and even Wimbledon. But scaling clean tech isn’t just about engineering. Williams talks candidly about navigating the “valley of death” between innovation and mass adoption and why education, policy, and patient capital are key to unlocking solar heat’s potential. He also shares how Naked Energy’s new software platforms, Clarity 24/7 and Clarity 360, are turning data into design, slashing project timelines and helping organisations that, as he puts it, “want to decarbonise but don’t know where to start.” From the challenges of grid electrification to the opportunities of heat decarbonisation, this episode dives into what it takes to scale climate innovation and why Williams believes solar thermal is finally ready for its moment in the sun.

    Ep.31 Asad Hamir, Klyk

    “E-waste is the world’s fastest-growing waste stream.” Entrepreneur Asad Hamir is tackling the growing e-waste crisis with his fourth venture Klyk, a circular IT company helping SMEs cut costs, extend the life of technology, and unlock the hidden value in discarded devices. Asad explains how Klyk’s model replaces new purchases with refurbished ones, manages those assets in life, and then collects, repurposes, or donates them at end-of-life. This approach not only reduces waste but monetising every stage of a device’s lifecycle. With target customers among fast-growing SMEs, Klyk helps founders save money, stretch limited runways, and adopt IT that’s both affordable and sustainable. Their strength also lies in customer support, positioning themselves as an outsourced IT team for their clients. Klyk’s growth comes at a time when right-to-repair laws and digital product passports are reshaping the tech industry, but Asad argues big manufacturers are still holding back true circularity by controlling parts and limiting accessibility. To counter this, Klyk has built out its IT services arm to reduce reliance on hardware sales and create sustainable recurring revenue. Bootstrapped with £1 million of his own capital, Asad has kept operations lean and prioritising services over hardware margins. He shares lessons for both founders and investors: stay focused, build on your strengths, and recognise that circular models represent one of the most profitable opportunities in business today.
