Instead of using ancient fossil carbons to make materials, a startup wants to utilize the greenhouse gas methane to create a new model of garment production. To do this, the startup is feeding waste methane to a certain type of bacteria that eats it and produces biodegradable bio-polyester fibers. These fibers can then be spun into thread, which can be used to produce clothing. Once the clothing is worn out, it can either be composted or sent to a landfill where it will biodegrade naturally.
