Coal ash includes a number of by-products produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler. Bottom Ash, a coarse, angular ash particle that is too large to be carried up into the smoke stacks so it forms in the bottom of the coal furnace.

In 2020, the average delivered price of coal to the electric power sector was $36.14 per short ton, which includes both spot and contract purchases. A more expensive coal is used to make iron and steel. In addition to producing electricity, coal is also used to produce coal coke, or coke, which is used in smelting iron ore to make steel.

What Makes Coal Valuable? Coal is a fossil fuel formed from dead plant matter trapped between rock deposits. Over a period of millions of years, biological and geological processes turn this material into peat and then through further metamorphosis into lignite, sub-bituminous coal, and finally anthracite coal.

Fossil fuels are the remains of organic material, such as plants and animals, which lived millions of years ago. Different fossil fuels are created depending on how long the material is buried, but it is generally accepted that the process takes millions of years. Fossil fuels are the product of a sort of natural geological "cooking".

Many industries use coal to manufacture certain products.

US coal power plants emitted more than 3.1 million tons of SO 2 in 2014. Nitrogen oxides (NOx): Nitrous oxides are visible as smog and irritate lung tissue, exacerbate asthma, and make people more susceptible to chronic respiratory diseases like pneumonia and influenza. In 2014, US coal power plants emitted more than 1.5 million tons.

In the case of coal, the commodity is typically bagged in either woven plastic or paper bags, which need to be sturdy enough to hold the weight of the coal and potentially withstand getting hefted around and stacked on. These bags can then be palletized to make it easier for warehouse workers to load and unload them onto the back of a truck.

Can we make steel with less coal? For a start, we could recycle much more than we do. Steel can theoretically be recycled indefinitely, with the remelting and alloying process ensuring its quality. That requires energy, but much less than to make new steel, and it needs no new source of carbon so is generally produced in electric arc furnaces.

We use to use the blender method to make recycled paper. It would take a little longer, but would still get the paper into pulp. Also, I was thinking you could take the squeezed pulp and smoosh it into smaller containers (butter tub, bottom of milk carton, etc) to get smaller "bricks" or different shapes. Love this idea!
