Aluminates Made Using New Raw Materials
A huge number of recent research studies have focused on an effective solution for waste treatment. This has led some residues to be made into new raw materials for many industries. Such an achievement ensures a reduction in energy and natural resource usage, decreasing of the negative environmental impact and creating new fields of work.
A good example comes from the metals industry, particularly the aluminum industry. Aluminum recycling is a beneficial activity for the environment, since it recovers resources from both manufacturing and consumer waste. Slag and scrap which were previously considered as waste, are nows the raw material for some highly profitable new industries. There is added-value in materials made using an aluminum residue which is currently considered as a hazardous waste. Current research is investigating the use of this waste to manufacture glass, glass-ceramic, boehmite and calcium aluminate.

Famous quotes containing the words raw materials, raw and/or materials:
“In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.”
—Henry David Thoreau (1817–1862)
“One farmer says to me, “You cannot live on vegetable food solely, for it furnishes nothing to make bones with;” and so he religiously devotes a part of his day to supplying his system with the raw material of bones; walking all the while he talks behind his oxen, which, with vegetable-made bones, jerk him and his lumbering plow along in spite of every obstacle.”
—Henry David Thoreau (1817–1862)
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
