Eco-friendly approach for converting agricultural wastes to useful construction

Agricultural activities have soared astronomically which
resulted to massive generation of agricultural wastes.
These agricultural wastes require proper handling to
prevent them from constituting an environmental risk
factor to human health. Agricultural wastes have been
found to be good pozzolanic materials (a supplement
or partial replacement for cement) in Civil engineering
construction works. In most cases, they have richer
chemical composition as construction materials when they
are incinerated to ash. The process of their conversion
to ash is purely a combustion reaction which inevitably
releases large amounts of carbon monoxide and carbon
dioxide into the atmosphere. These gaseous substances are
very poisonous and as such are global problem. The careful
handling of these dangerous gases during the process of
conversion to ash has received very little attention in
previous studies. Therefore, this paper recommended a
simply designed system arrangement for the combustion
of the agricultural wastes to ash and provision for the
conversion of the poisonous gases into substances that are
of economic value to man to save the atmosphere.
