Scaling nature: biomanufacturing and the rise of the bioeconomy

Biomanufacturing, the process of producing goods and materials using biological systems, is at the forefront of the bioeconomy.

By harnessing the power of living organisms, biomanufacturing offers sustainable alternatives to traditional industrial processes, addressing global challenges such as climate change, resource scarcity, and food security. This article explores the advancements, applications, and challenges of biomanufacturing, with a focus on its potential to drive the bioeconomy and create a sustainable future.

Advancements in biomanufacturing

Biomanufacturing has evolved significantly due to advancements in biotechnology and synthetic biology:


  1. Precision fermentation
    Precision fermentation enables the production of complex molecules, such as proteins and enzymes, by programming microbes. Companies like Perfect Day use this technology to create animal-free dairy proteins.
  2. CRISPR and gene editing
    Gene-editing tools like CRISPR have revolutionised the engineering of microbes, plants, and cells, enabling the production of bio-based materials with high efficiency.
  3. Bioreactor innovations
    Next-generation bioreactors have increased the scalability of biomanufacturing. Modular and automated systems allow for flexible and cost-effective production.
  4. Automation and AI integration
    Artificial intelligence accelerates the design-build-test cycle in biomanufacturing, optimising processes and reducing time to market. Companies such as Zymergen and Ginkgo Bioworks leverage AI to design high-performing microbial strains.


Applications of biomanufacturing

Building public trust in biomanufactured products, particularly in food and healthcare, requires transparent communication and robust safety standards.

Biomanufacturing is revolutionising diverse sectors of the global economy:

  1. Food and agriculture
    • Alternative proteins
      Precision fermentation produces plant-based and cell-cultured meat, offering sustainable alternatives to traditional livestock farming.
    • Sustainable farming inputs
      Engineered microbes produce biofertilisers and biopesticides, reducing the environmental impact of agriculture.
  2. Healthcare and pharmaceuticals
    • Biologic drugs
      Biomanufacturing enables the production of complex biologics, such as monoclonal antibodies and insulin.
    • Vaccines and therapies
      Rapid development and scalable production of vaccines, such as mRNA COVID-19 vaccines, exemplify biomanufacturing’s impact on healthcare.
  3. Industrial and consumer goods
    • Bioplastics
      Biomanufactured plastics derived from renewable sources provide an eco-friendly alternative to petroleum-based plastics.
    • Bio-Based textiles
      Companies like Bolt Threads produce biofabricated materials, such as spider silk, for sustainable fashion.
  4. Energy and environment
    • Biofuels
      Biomanufactured fuels, including ethanol and biodiesel, offer renewable energy alternatives.
    • Bioremediation
      Engineered microbes break down pollutants, such as oil spills and plastics, contributing to environmental restoration.
