Recircle Limited Secures £625k to Advance Rubber Waste Recycling Technology

Recircle Limited, a London-based industrial biotechnology company, has raised £625k in a new funding round, reaching an estimated post-money valuation of £4m. The company specialises in sustainability technology for the rubber industry, converting rubber waste into high-quality feedstocks for manufacturers.

Founded in June 2015, Recircle addresses a critical environmental challenge: the global accumulation of rubber waste. Historically, rubber products, particularly those that have been cured or vulcanised, are notoriously difficult to recycle. The vulcanisation process creates strong chemical bonds that make the material durable but resistant to breaking down. Recircle develops advanced biotechnology and material science processes to overcome this barrier, recycling both uncured and cured rubber waste.

By giving new life to these materials, Recircle enables customers within the rubber value chain to substitute unsustainable virgin raw materials with high-quality recycled rubber compounds. This process directly assists manufacturers in cutting their carbon emissions, reducing landfill waste, and transitioning towards a circular economy model.

The firm currently employs 42 people at its London headquarters. Specific financial metrics, such as revenue and profit or loss figures, were not disclosed in the latest corporate filings.

The latest equity allotment was filed on 24 March 2026, following an allotment date of 5 March 2026. The transaction brings in £625k of fresh capital, valuing the business at an estimated £4m post-money. The identities of the investors participating in this round have not been publicly named in the filings. Due to the limited public data on prior investments, it is not immediately clear how this valuation compares to previous funding rounds.

Recircle's funding arrives amid a broader surge of interest in the UK clean technology and circular economy sectors. Recent industry data indicates that sustainability-focused startups now account for between 15 and 20 percent of early-stage funding in the UK. The broader UK cleantech sector secured over £5bn in investment in 2024, driven by a national push towards net-zero targets and industrial decarbonisation. Investors are increasingly directing capital toward companies that offer tangible material science or deep tech solutions to climate problems.

Furthermore, London has become a prominent hub for circular economy innovation, supported by local government initiatives and grants aimed at reducing waste across various supply chains. Recircle's focus on material science and industrial biotechnology positions it within a growing cohort of UK enterprises aiming to decarbonise heavy industries. By providing a commercially viable alternative to virgin raw materials, the company is capitalising on the increasing regulatory and commercial pressure on manufacturers to improve their environmental footprints and adopt sustainable supply chain practices.
