Fly Ash - The Problem Based on a study undertaken by the
WORLD COAL INSTITUTE, London, U.K. approximately
3.8 Billion metric tonnes of coal are mined worldwide each year. After
conversion of the coal into, for example, electricity approximately
400,000,000 metric tonnes of Fly Ash are left as residue as well as other
waste products. Approximately 10 % of the Fly Ash is used as
a by-mix for other products such as cement, etc. Almost 90 % is tipped onto
spoil heaps or down mines, causing ecological problems.
As a consequence: large areas, quite often attractive
countryside or valuable farm land, are changed into ugly ash tips,
soil and groundwater are polluted, erosion and
dust cause serious safety and health problems.a valuable raw material is wasted.
However this is a problem that can be solved by using the IVU-DISPERSOPT
Process! Fly Ash - The Solution to the Problem!Using the
IVU-DISPERSOPT Process means: instead of huge ash
tips and polluted ground and subteranean water, an ecologically safe building
material,
of considerable environmental and commercial value, is produced, instead of
excessive exploitation of natural resources (lime, dolomite, etc.)
many processes will require greatly reduced mineral resources because there
is an economically useful substitute now available,
instead of polluting the land with waste tips full of dangerous substances these
can be immobilised completely and the end product, a building
maerial, is totally safe, instead of using costly energy in the process, the
chemical reaction only requires water and creates no waste problems,
and even the water is resed instead of time consuming, and costly, preparations
for clay used in the cement and brick industries the processing
can be reduced to only a few minutes, instead of using expensive flue gas cleaning
processes, sulphure emissions from burning coal can be reduced significantly
by applying a desulphuriation sorbent.
