The circle of it: This company replaces metal-and-silicon RFID tags with fully recyclable, chipless paper tags — cutting CO2 emissions by 60% and costs by 30%
PULPATRONICS
Summary
PulpaTronics is a London-based deep tech startup developing fully recyclable, metal-free, chipless RFID tags made from paper. RFID (Radio Frequency Identification) tags are widely used across retail, logistics, and transportation to track inventory, prevent theft, and enable auto-checkout — yet around 18 billion are produced globally each year as single-use items, becoming one of the fastest-growing waste streams in Europe. Traditional tags contain a metal antenna and a silicon microchip, making them incompatible with standard recycling. PulpaTronics solves this by using laser technology to induce a conductive carbon circuit directly onto paper, encoding data in the geometric pattern of the material rather than in a chip — much like a QR code stores information in its shape. The result is a tag that performs the same functions as conventional RFID but can be recycled alongside ordinary paper waste. The company estimates its tags cut CO2 emissions by 60% and reduce manufacturing costs by 30%, and has been recognised as a B Corp. (Source)
Story
PulpaTronics was co-founded by Chloe So and Barna Soma Biro, who met on the first day of a dual master’s programme in Innovation Design Engineering taught jointly by Imperial College London and the Royal College of Art. The idea emerged from a final-year group project in late 2022, driven by a shared frustration: as we move toward a more digitalised world, the hidden environmental cost of single-use electronics was going largely unnoticed. Chloe, who had previously worked at a venture capital accelerator in New York, had become increasingly aware that more products often means more harm to the planet. Soma, with a background in biology and a passion for turning scientific research into real-world solutions, brought the technical drive. Together they embraced the concept of “substraction” — adding value by removing complexity rather than adding it. The company was formally founded in 2023 and has since raised pre-seed funding, run pilot studies with major UK retailers, and grown its team with specialists in laser engineering, radio frequency, and materials science.

“We check the sustainability box, and we check the price-point box, and I think that’s why investors were so excited about this product and willing to give us their money.“
