Post Carbon Lab secures £62k to scale carbon-absorbing textile coatings

A London-based biotech firm specialising in carbon-absorbing textiles has raised an estimated £62k in new funding. Post Carbon Lab Ltd, which is headquartered in the E14 area of the capital, reached an estimated post-money valuation of £3.6m following the transaction.

The company was incorporated on May 28, 2020, to address sustainability challenges within the textile and polymer industries. Post Carbon Lab provides microbial finishing and coating services, with a primary focus on its Photosynthesis Coating technology. This specific application allows fabrics to absorb carbon dioxide from the surrounding environment, mimicking the natural processes of plants.

The business operates as a B2B service provider, targeting designers and brands across the fashion, interior, automotive, and product design sectors. While the technology has broad industrial applications, the company currently prioritises partnerships with small and medium-sized enterprises across Europe. Its microbial solutions are marketed as climate-positive and cost-effective alternatives to traditional chemical-based textile treatments.

Financial records indicate that the company maintains a small team, with three employees listed in the latest accounts and two employees noted on its professional social media profile. The allotment of shares for this latest funding round occurred on April 4, 2026, with the official filing completed on May 3, 2026.

Post Carbon Lab aims to provide the textile industry with microbial colour and finishing solutions that reduce the carbon footprint of manufacturing. By integrating biological processes into fabric production, the company seeks to solve the problem of high carbon emissions associated with standard textile finishing.

The company's reach extends into the automotive industry, where its coatings can be applied to interior fabrics, and the interior design sector for use in upholstery and other soft furnishings. By focusing on SMEs in Europe, Post Carbon Lab provides accessible biotech solutions to businesses that may lack the resources to develop proprietary carbon-capture technologies.

The £62k raise was documented in a filing on May 3, 2026. This latest capital injection supports the company's ongoing work in microbial research and the commercial application of its Photosynthesis Coating. The current valuation of £3.6m places the biotech firm within the early-stage growth category for UK-based sustainable technology companies.
