US Bitcoin mining firm turns to harmful coal waste for cleaner energy
In a bid to make crypto mining more environmentally friendly, Stronghold Digital Mining is turning harmful waste from coal mining into clean energy to power Bitcoin miners.
Stronghold Digital Mining (SDIG), a crypto mining company in Pennsylvania, is turning waste from old power plants into energy to power hundreds of Bitcoin mining rigs.
The company collects coal refuse, a leftover waste material from the process of coal mining, and burns it in what it says is an emissions-controlled environment at its energy generation facilities.
Coal refuse can cause a raft of environmental problems such as water and air pollution and acid mine drainage, the acidic water which comes from coal mining operations. Collecting this waste and safely disposing of it while generating power for crypto mining is a productive way of tackling the problem.
Last August, Argo Blockchain, a United Kingdom-based crypto mining company, announced its operations had become climate positive on its greenhouse gas emissions. Its planned 200 MV mining facility in Texas is also set to run on renewable energy.
