Bagasse is commonly used as a fuel in cogeneration to produce steam and generate electricity. In this process, sugar cane bagasse ash (SCBA) remains as the final waste in the sugar production chain. Each ton of burnt bagasse may generate 2540 kg of bagasse ash [ 10] and, subsequently, a considerable amount of SCBA could be generated.

In this work, a planetary ball milling was used to modify the surface properties of calcitebased material from waste oyster shell under the rotational speed of 200600 rpm, grinding time of 5180 min and sample mass of 110 g. The milling significantly changed the microstructural properties of the calcitebased minerals (, surface area, pore volume, true density, and porosity). The ...

oyster shell, ball milling, powder material, surface characterization, true density. It is well known that the oyster shell is a natural biomaterial with excellent fracture strength and hard toughness, which are attributed to its laminated microstructure [ ]. This mineral material is primarily composed of calcium carbonate (CaCO, calcite) laid ...

A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier machine and other types of paper machine that use an endless belt, all paper in a paper mill was made by hand, one sheet at a time, by specialized laborers.
