Evidence and lessons from Latin America (Ella, 2012) brief illustrated and summarized the advantages and disadvantages of switching from manual to mechanized sugarcane harvesting in Brazil. The brief showed that pre-harvest burning of sugarcane leaves is a common practice that enables manual pickers to collect the crop quickly, suffering less personal injury. The burning process, however, has negative impacts on the environment, on human health and on the potential energy value of the plant. On the other hand mechanization eliminates the need for burning, speeding up the collection process, eliminating harmful emissions from smoke, reducing crop wastage and thus increasing productivity in terms of energy generation. Electricity generated from sugarcane biomass can also be sold to the grid, increasing both producers’ income and the national energy supply.
Table 2 indicates clearly the effect of the rehabilitation work and the renewal of the equipment carried out in Sennar by Sudanese Sugar Company from year 1993 onwards and till now the follow up is going on which leads to improvement year after year.
