Renewable biomass fuel as 'Green Power' alternative for sugarcane milling in the Philippines.

摘要: The potentials of three renewable biomass types as 'Green Power' alternatives for sugarcane milling were evaluated: (1) baled trash, (2) high-yielding perennial grass (ie, Napier grass), and (3) fast-growing tree species. data shows that approximately 5.9% energy used boilers in sugar processing, provided by 365,000 barrels imported bunker oil, can be displaced 246,000 tonnes (at 26% moisture) cane trash. This trash volume represents 50% the 496,000 recoverable (low estimate), harvested following final ratoon crop a 3-year planting-harvesting cycle. cost producing was projected to 7% higher than harvesting, mainly due land lease crop. A purchase price equal (US$ 31.73/ tonne) will likely encourage farmers plant Napier. main concern with fastgrowing trees is relatively longer period would have wait prior receiving an economic return. Also, promoting wood biofuel use contribute further deforestation problems Philippines. Sugar refineries been cited major cause past. Overall, economic, environmental social implications utilizing year substitute oil appears most promising Philippine industry. Positive socio-economic impacts include provision rural employment minimization imports. It also develop expertise necessary create reliable supply year-round power generation. Investment research development these technologies essential effective utilization system future.
