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,
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
- 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!
