Estudio del impacto ambiental del uso del bagazo como fuente de energía en centrales azucareros en Cuba. Estudio de caso "Melanio Hernández"

This work was carried out to study the environmental impacts produced by power generation from biomass (bagasse) in sugar mills in Cuba. For this purpose, with the collaboration of the Center for Energy and Industrial Processes (CEEPI), the University Center of Sancti Spiritus and using different research methods and techniques, conducted an environmental survey of the area. Gaseous emissions were characterized and the suspended solid particles, allowing knowing that these concentrations do not exceed the maximum emission limit set by the cubana Standard. In addition, the dispersion model applied DISPER allowed us to obtain information in crisis conditions of air emissions from sugar mill and distillery associated and concluded that emissions from the distillery are the pollutants that contribute more the atmosphere. The correlating emissions with respiratory diseases, (acute respiratory infections or subacute (IRA) and ASMA), concurrent Asthma Crisis (CAB) is the most affected. The calculated costs associated in these diseases, amounting to $ 119 599.23 per year. In order to minimize the negative alternatives are proposed to be implemented in industry and community.

Phosphine fumigation of silo bags.

Fumigation with phosphine has the potential to disinfest grain stored in silo bags but only limited research has been conducted on whether phosphine fumigation can be undertaken effectively and safely in this form of storage. Fumigation with phosphine was tested on two (70 m) replicate silo bags each containing 240 t of wheat (9.9 and 9.2% m.c.). The target application rate of phosphine was 1.5 g m 3 with a fumigation period of 17 days. Aluminium phosphide tablets were inserted into each bag at ten release points spaced at 7 m intervals starting 3.5 m from either end of the bag. A total of 14 bioassay cages containing mixed age populations of strongly phosphine resistant Rhyzopertha dominica (F.) were inserted into each fumigated silo bag. Complete control of all life stages of R. dominica was achieved at all locations in the fumigated silo bags. Phosphine concentrations at release points increased rapidly and remained high for the duration of the fumigation. Concentrations at midway points were always lower than at the release points but exceeded 215 ppm for ten days. The diffusion coefficient of available phosphine averaged over the first three full days of the fumigation for both fumigated silo bags was 2.8 x 10 7. Venting the silo bag with an aeration fan reduced the phosphine concentration by 99% after 12 h. Relatively small amounts of phosphine continued to desorb after the venting period. Although grain temperature at the core of the silo bags remained stable at 29degreesC for 17 days, grain at the surface of the silo bags fluctuated daily with a mean of 29degreesC. The results demonstrate that silo bags can be fumigated with phosphine for complete control of infestations of strongly phosphine resistant R. dominica and potentially other species.
