Landfill mining projects and mining companies will receive renewable energy credit, which will be administered by a program put in place by the World Trade Organization (visit the inernational regulations page for more information. These incentives make landfill mining more economically viable to new companies wishing to enter the market.
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
