Agricultural Wastes as Useful Eco-friendly Construction Materials. Green Technology

      Аннотация: 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
