The Future of Green Chemicals: Blue-Green Algae Takes Center Stage

As the world races to decarbonize industries, sustainable chemical production has become a critical frontier. U.K.-based startup Deep Blue BioTech is pioneering an innovative approach using cyanobacteria (blue-green algae) to create high-performance, eco-friendly chemicals for skincare and beyond.

Photosynthetic Biomanufacturing: A Game-Changer

Founded in May 2023, Deep Blue BioTech leverages:

  • Genetically engineered cyanobacteria (single-cell prokaryotes, not true algae)
  • Photosynthesis-based production requiring only light, water, and CO₂
  • Computational modeling to optimize chemical outputs

This method offers two key advantages:

  1. Carbon-negative process: Consumes more CO₂ than it produces
  2. Cost parity with conventional petrochemical methods

“Our technology creates superior green chemicals that outperform traditional options,” explains co-founder Manuel Rios, former VP of Sustainable Design at Unilever.

Why Cyanobacteria Outshine Other Bio-Based Methods

Compared to precision fermentation (which requires expensive sugar feedstocks), Deep Blue BioTech’s approach:

  • Uses 3x faster-growing cyanobacteria strains
  • Delivers 7x higher productivity
  • Features simpler downstream processing

“This breakthrough removes the commercialization barriers that previously held back photosynthetic biomanufacturing,” notes Rios.

Market Strategy: Beauty First, Textiles Next

The startup is initially targeting the $500B+ beauty industry with:

  • High-performance hyaluronic acid (first product)
  • Low molecular weight formula for better skin penetration
  • Multiple letters of intent from cosmetic brands

Future verticals include:

  • Sustainable textile dyes
  • Medical applications
  • Biofuels (considered but deprioritized for slower commercialization)

$800K Pre-Seed Funding Accelerates Development

The recent funding round led by Sustainable Ventures will support:

  • Commercial MVP development (small-scale production demonstrator)
  • Paid pilot programs with beauty partners
  • Second ingredient R&D (likely textile dyes)
  • Patent filings and team expansion

Competitive Edge in Green Chemistry

While compe*****s like France’s Microphyt and Australia’s Bondi Bio work with similar organisms, Deep Blue BioTech differentiates through:

  • Industry-specific chemical formulations
  • Modular photobioreactor systems for easy scaling
  • Focus on both sustainability AND performance

“We’re not just making green versions of existing chemicals,” emphasizes Rios. “We’re engineering superior molecules that happen to be sustainable.”
