Bacteria Nanocellulose Leather

Speculative Surfaces is a textile company based in Chicago, IL, currently developing lab-grown leather from bacteria and yeast.

This novel material is grown by fermenting infinitely renewable bacteria-nanocellulose (BNC) and grows within weeks. Bacteria and Yeast form interlocking fibers that produce a pellicle, ready to harvest, neutralize, dry and finish. Growing BNC material consumes little water, utilizes abundant resources (sugar) and emits no greenhouse gases or toxic waste products. This growth method allows control over the desired thickness and dimensions of the material.

Through lab-grown leather, we can replicate qualities most desired in leather and envision a material thicker than any animal collagen possible. We can eliminate the use of animal hides and harsh chemicals like Chromium and replace them with bacteria and yeast; infinitely renewable and ethical resources.

Our goal is to address the toxicity of the leather industry and create a product that can replace these current modes of production. From biodegradable packaging to faux leather for upholstery, our methods of operation prove to be expansive and scalable. Through the use of vertical farming and regenerative growth cycles, BNC leather is a sustainable alternative to conventional leather.

Our material is currently undergoing the following textile testing: Tensile strength, water contact angle, flex bally test, and overall quality testing.
