Bitcoin mining company Marathon Digital has launched a pilot project in Utah that uses methane gas from landfill waste to generate electricity for its mining operations. The company partnered with renewable energy firm Nodal Power for the 280 kW test project, which may be expanded if successful. Other mining companies have also been exploring alternative energy sources to power their operations and reduce greenhouse gas emissions, such as using wasted natural gas. Marathon CEO Fred Thiel said the project could help the company diversify its operations, lower energy costs, and improve the environment.
