Within capitalism, many commercial brands grow at the expense of the environment, contributing to degenerative systems, and leading to the irreversible damage of the Earth. Knowing this, how might we develop a method for brands to interact with its environment in a sustainable way? This research aims to find a lens for designers to rethink their current methods and bring about positive change through the interactions of brands with and within their environments. The outcome of this research is a regenerative model inspired by fungal mycelium, The Mycelial Framework, which is meant to guide brands towards sustainability by collaborating through symbiotic interactions.
