Arq recycles and transforms coal waste into an entirely new source of high-value energy.

Making the world’s resources go further

Arq is using cutting-edge technology and scientific rigour to shake up the energy market. Our patented process unbinds microfine hydrocarbon particles from coal waste, by breaking it down into its elemental parts.

We strive to produce the lowest cost energy products – without compromising on performance – while cleaning up a serious environmental liability in the process.

Our solution is radically different from previous attempts to convert coal into liquid fuels, providing a simpler, economically viable alternative.


Tackling a global problem

Our process supports the recommendations set out by the UN Environment Programme, cleaning up a serious environmental liability by reclaiming and regenerating coal refuse sites.
