Company profile
researched Sep 2026Alkemy Environmental is a clean technology company that converts industrial waste streams into structural-grade lightweight concrete aggregate. Its process is described as a waste-to-ceramics recycling technology that produces high-strength building materials from industrial byproducts, with the stated aim of reducing hazardous landfilling.
The resulting aggregate is described as structural grade and LEED accredited, and is targeted at ready-mix concrete, masonry, precast concrete, roadwork, and other sustainable building and infrastructure applications. The company positions industrial byproducts as inputs that can be recycled rather than disposed of, allowing generators of those waste streams to lower disposal costs and convert waste liabilities into materials with commercial value.
Business model
Alkemy applies its recycling technology to industrial waste streams to produce lightweight aggregate products sold for construction applications, while offering industrial waste generators a route to convert disposal liabilities into a revenue-generating asset. The company also references custom solutions and services alongside its material products.
