Abstract

The generation of large amounts of ash from sugarcane bagasse by its
producing countries is becoming a worldwide-problem. Its irregular
application, such as in fertilizers, contaminates soil and water, causing a
great environmental problem. Studies show it is possible to apply ash in
some specific areas, such as replacement of portland cement, replacement
of clay, as an adsorbent, in the treatment and stabilization of soils, in the
pavement of road asphalt, among others. The objective of the present article
is to evaluate which are the most promising areas for the use of sugarcane
bagasse ash. The work was developed with a bibliographic search, using
the bibliometrics technique. The results obtained show that it is possible to
use ash in several different areas. However, having a detailed study of the
characteristics of the ash obtained is important, because they are directly
related to the regions and climates where sugarcane is cultivated, besides
its granulometry, collection time the ashes in the boilers, pHs, curing time,
etc. In conclusion, results can be very different for the same application area,
depending on the properties of the ash obtained.
