In Sweden, the mining industry accounts for over 80 percent of the countrys total waste production each year. While the amount of waste can be substantial, not all waste is considered harmful to the environment. Some waste might even be safe to use in other applications, such as in building materials.

Green Energy Reality Check Its Not As Clean As You Think

Green Energy Reality Check Its Not As Clean As You Think Jul 09, 2020 Green machines mean mining more materials per unit of energy delivered to society. Since clean tech is about supplying energy in a more sustainable fashion, one needs to consider not just the physical mining realities but also the hidden energy costs of the underlying materials themselves, i.e., the embodied energy costs.Jul 09, 2020 Green machines mean mining more materials per unit of energy delivered to society. Since clean tech is about supplying energy in a more sustainable fashion, one needs to consider not just the physical mining realities but also the hidden energy costs of the underlying materials themselves, i.e., the embodied energy costs.Mining was the chief industry for miles around. 1861 saw the completion of the first copper-rolling mill. Federal troops occupied Cleveland in 1863. The mill was burned and mining ceased until 1865. During the early mining days, mules pulled ore cars underground.
