Modern Synthesis

Modern Synthesis is a London‑based biomaterials venture founded in 2019 that “weaves” bacterial nanocellulose into non‑woven textiles. The firm engineers cellulose‑producing bacteria to spin fibres directly onto 3‑D frameworks, eliminating the need for looms or chemical dissolution. Its patent‑pending microbial‑weaving platform feeds microbes agricultural sugars and captures the resulting pellicle as a leathery composite with high tensile strength and tunable hand‑feel.

Life‑cycle assessments indicate double‑digit reductions in carbon, water and chemical loads versus chrome‑tanned hide, while mechanical data show tear resistance that already meets ISO 3376 for leather goods. A £4.1 million seed round (2022) financed a pilot line that now outputs 30,000 m² yr and supplies R‑&‑D rolls to fashion and automotive brands. The company’s go‑to‑market strategy couples direct sheet sales with future licensing of its bioprocess to contract manufacturers.

In 2024 it delivered its first commercial part—the Bou Bag panels for Danish label GANNI—demonstrating geometry‑specific growth and 40 % material savings relative to cut‑and‑sew leather.
