Stronghold Digital Mining (SDIG), a Pennsylvania-based crypto mining company, is converting waste from old power plants into energy to power hundreds of bitcoin mining rigs.
The company collects tailings coal, a leftover waste material from the coal mining process, and incinerates it in what it says is an emissions-controlled environment at its power generation facilities.
Coal waste can cause a number of environmental problems such as: B. Water and air pollution and acidic mine drainage, the acidic water that comes from coal mining. Collecting and safely disposing of this waste while generating electricity for crypto mining is a productive way to address the issue.
The state of Pennsylvania is the third largest producer coal in the United States, estimates put the amount of wasted coal at 881 pounds per 2,200 pounds mined or 400 kilograms per tonne. Stronghold estimates that Pennsylvania alone generates over 220 million tons of hazardous waste.
Bitcoin and other proof-of-work cryptocurrencies have recently attracted the attention of regulators as they rely on energy-intensive processes to mine and validate the network.
Earlier this month, New York State presented a proposal Suspension of proof-of-work mining using fossil fuels was introduced citing the negative environmental impact of the process, the proposal was put forward by the New York State Assembly today. If passed, proof-of-work mining in New York could be suspended for up to 3 years.
Other systems have seen ways to make bitcoin mining eco-friendly. Earlier this month, oil drilling company ConocoPhillips started a program in North Dakota, where it would be sell the natural gas by-product from its operations to bitcoin miners instead of burning them.
Last August, Argo Blockchain, a UK-based crypto mining company announced that his company had become “climate positive”. on its greenhouse gas emissions. It is planned 200 MW mining plant in Texas is also to be operated with renewable energy.
