Erica Stine's Sustainable Fly-Ash Chair,

In an effort to reduce global greenhouse gas emissions, Savannah College of Art and Design (SCAD) furniture design graduate student Erica Stine created the Fly-Ash chair, a modern and eco-conscious chair constructed entirely of recycled coal waste. 

The Fly-Ash Chair is constructed of a geopolymer concrete primarily comprised of waste from coal-based power plants. The volume of ash byproduct in each chair is the energy equivalent of a 100W lightbulb powered for 24 hours a day for 115 days.

The sustainable furniture design concept recently earned a notable honor in the 2020 international Red Dot Design Competition's "Home Furniture" category.

The Ground Granulated Blast Furnace Slag (GGBS/GGBFS) is a type of eco-friendly green building material and high quality secondary cementitious material for concrete and cement. It is recognized as one of the best secondary cementations material for building high durable concrete stricture in the world today! GGBS has taken over top place of high performance cement and concrete mineral additives with its unique characteristics of hydration, low-price raw material.

Fly ash is a by-product produced while burning finely ground coal in a boiler to produce electricity. It is removed from the plant exhaust gases primarily by electrostatic precipitators or baghouses and secondarily by scrubber systems. Physically, fly ash is a very fine, powdery material, composed mostly of silica. Nearly all particles are spherical in shape. Fly ash is a pozzolan, a siliceous material which in the presence of water will react with calcium hydroxide at ordinary temperatures to produce cementitious compounds. SiO2, Al2O3, Fe2O3 and occasionally CaO are the main chemical components present in fly ashes.
