Mechanisation of sugarcane harvesting is growing rapidly in Southern Brazil where nearly 80% of Brazil's crop is cultivated. Currently a maximum of 20% of the cane is mechanically harvested and the proportion is expected to rise to about 50% by 2005. However, most of the cane is burned prior to harvesting and less than 2% is harvested green. Issues such as topography, crop cultivation and management methods, labour costs, machine performance, environmental legislation and markets for sugarcane residues will influence the increase in mechanical harvesting of burned or green cane. This paper discusses the prospects for green cane harvesting technology, with emphasis on Southern Brazil, and compares harvesting technologies which are being commercialised today. The paper also addresses the recovery of cane residues (dry and green tops and leaves) and comments on their possible use and commercialisation, particularly for electricity generation.

Faaij A, Meuleman B, Turkenburg W, et al., 1998, Externalities of biomass based electricity production compared with power generation from coal in the Netherlands, BIOMASS BIOENERGY, Vol: 14, Pages: 125-147, ISSN: 0961-9534
Externalities of electricity production from biomass and coal are investigated and compared for the Dutch context. Effects on economic activity and employment are investigated with help of input/output and multiplier tables. Valuations of damage from emissions to air are based on generic data from other studies. In addition external costs are estimated for nitrogen leaching and for the use of agrochemicals for energy crop production. The average private costs for biomass and coal based power generation are projected to be 68 and 38 mECU/kWh, respectively in the year 2005. It is assumed that biomass production takes place on fallow land. Coal mining is excluded from the analysis. If the quantified external damages and benefits are included the cost range for bio-electricity is 53-70 mECU/kWh and 45-72 mECU/kWh for coal. Indirect economic effects (increment of gross domestic product) and the difference in CO2 emissions are the most important distinguishing factors between coal and biomass in economic terms. Damage costs of other emissions to lair (NOx, SO2, dust and CO) are of the same order of magnitude for both coal and biomass (coal mining excluded). In this analysis environmental impacts of energy farming are compared mainly with fallow land focused on the use of fertilisers and agrochemicals. The related damage costs appear to be low but should be considered as a preliminary estimate only. The quantitative outcomes should not be considered as the external costs of the two fuel cycles studied. Many impacts have not been valued and large uncertainties persist, e.g. with respect to the costs of climate change and numerous dose-response relations. More detailed analysis is desired with respect to macro-economic impacts. The results serve as a first indication, but the outcomes plead for the support of bio-electricity production and/or taxation of coal-based power generation.
