The GOB mycelium earplugs are biodegradable noise-reducing plugs grown from fungal material rather than manufactured from petroleum-based foam. Designed as a direct replacement for traditional disposable earplugs, they use aerial mycelium to create a soft, porous structure that conforms to the ear canal without the expansion pressure of polyurethane foam. The material is biofabricated as a single-ingredient foam, eliminating synthetic binders while maintaining comparable acoustic performance.
The earplugs provide noise reduction in the range of 12 to 25 decibels, suitable for concerts, travel, and everyday noise exposure. Their compostable composition allows them to break down into nutrients after use, addressing the environmental impact of billions of single-use plastic earplugs discarded annually. GOB partnered with live event organizers to place the product directly at concerts and venues
Biodegradable Mycelium Earplugs
GOB Earplugs Use Fungi-Based Foam to Replace Disposable Plastic
Trend Themes
-
Mycelium Biofabrication — A scalable fungal cultivation platform capable of producing soft, porous materials presents alternatives to petroleum-based foams across acoustic and cushioning applications.
-
Compostable Single-use Alternatives — Materials engineered to biodegrade into nutrients after short service lives create opportunities to eliminate plastic waste from high-volume disposables such as earplugs and packaging.
-
Venue-embedded Product Distribution — Embedding sustainably produced consumables directly into live-event ecosystems enables new product placement models tied to experiential consumption and brand visibility.
Industry Implications
-
Live Events and Entertainment — Event organizers and venues can integrate biodegradable audience amenities to reduce waste footprints while aligning with sustainability-focused sponsorships and guest experience enhancements.
-
Personal Protective Equipment — Replacing synthetic foams with biofabricated, compostable materials offers a path to lower environmental impact for hearing protection, disposable masks, and other single-use PPE.
-
Consumer Hearing Accessories — Retailers and brands in the ear care market may benefit from soft, conforming mycelium foams that provide tailored acoustics and end-of-life compostability for mainstream consumers.
