Linus Larsson Green is the co-founder and CEO of PulPac, a Swedish deep-tech company pioneering dry moulded fibre, a breakthrough manufacturing technology that turns cellulose pulp into packaging and single-use products that can fully replace plastic.

Every year, we produce more than 400 million tons of plastic, with a huge chunk of that used just once but PulPac are tackling that problem head on… PulPac’s unique process uses 90% less water than traditional methods and slashes carbon emissions, while still retaining the ability to mass-product fibre cups, trays and lids at global scale.

Over the last 7 years, PulPas has raised major funding, built a network of international licensees and partnered with some of the world’s biggest packaging players. I’m very much looking forward to hearing about this journey in more detail

Today, I’m speaking with Armando Leal Puente, co-founder and managing director of Eutechtics, a deep-tech startup based in Sheffield, that’s taking on one of the biggest challenges in climate and industry - decarbonising the chemical supply chain.

Eutechtics has built a platform called EvoCarbon, which turns captured CO₂ into valuable chemical building blocks - things like carboxylic acids that go into everyday products such as cosmetics, food ingredients, pharmaceuticals and even plastics which are currently made using fossil fuels.

Armando and his team are reimagining how we make the molecules that power modern life, proving that sustainability and profitability don’t have to be at odds. In just a few years, they’ve secured national innovation funding, won major cleantech awards, and attracted the attention of investors and industry alike.

Fabien Koutchekian is the co-founder and CEO of Genomines, a start-up pioneering the extraction of nickel from the ground.

Instead of bulldozers and explosives, Genomines uses genetically enhanced plants, called hyperaccumulators, to pull nickel out of the soil. The result is a process that could deliver battery-grade metal with a fraction of the environmental footprint of traditional mining. With such transformational potential, it’s not a surprise that they successfully closed an incredible $45m Series A raise in September 2025.
