As it stands, there are approximately 1.35 million tons of husk waste generated from the coffee production industry, per year. The goal is to divert the by-product materials and form a compostable alternative cup.
Technical: The coffee fruit is comprised of an outer skin, called the husk, a layer of pulp beneath that, and a type of parchment that wraps the bean, also known as the hull. These materials have their individual properties but a combination of the skin and pulp can potentially form a water proof, and temperature-retaining form. We can compress these materials within a cup-shaped mold, and if necessary, allow mycelium to grow within the remaining pores of the material to form a watertight seal. As these are all organic materials, we wouldn't run into chemical leaching from container to the liquid it is holding.
Business: As manufacturers would buy the coffee bean by-products, this business plan would incentivize coffee production facilities to collect their waste and become zero-waste facilities. This would in turn potentially boost the economy and protect the local water from contamination.
