ARQ

Arq, Inc.

An environmental technology company that turns coal into activated carbon that pulls pollutants like mercury and PFAS out of air, water, and soil for power plants, industry, and city treatment plants. It began in 1997 as ADA Environmental Solutions, a coal-emissions specialist, later known as Advanced Emissions Solutions until it rebranded as Arq in 2024. The name came from buying Arq Limited, whose "arq" evoked earth and all-around solutions — fitting for a cobalt-blue logo that symbolizes air, water, and soil.
