Title StatementMeasuring the economic and environmental benefits of high pressure sap displacement technology for treating poles
General NoteCollege, Laguna: UPLBCF, 1995. 108 p
Summary, Etc.The study determined the economic and environmental benefits derived by selected cooperatives and other direct beneficiaries by adopting the high pressure sap displacement (HPSD) technology for treating poles. Data were gathered from adoptors of the technology, sellers of raw poles, the pressure cap fabricator, a firm using the vaccum/pressure treatment method and other relevant institutions. Analysis of the data was done by simple net returns, cash flow, percentage and chemical analysis. The HPSD technology benefited the adoptors through savings generated from treating their own poles rather than buying already treated ones. Other benefits of the technology were: development of manpower skills, and added income to sellers of raw poles (growers and middlemen) and to the pressure cap fabricator. The cost of treating electric poles through HPSD technology was cheaper than the cost of treating similar size of poles through the vaccum/pressure treatment method. Moreover, the present value of the cost of using HPSD technology treated poles was less than the present value of cost of using vaccum/pressure treated poles. The HPSD technology also contributed, to some extent, in the electrification program of the government through the delivery of electric power especially to less accessible and far-flung barangays. Furthermore, the results also showed that in the HPSD technology treatment sites, concentration of copper and chromium in the soil were greater than those in the off-site. The concentration decreased as the time elapsed after treatment increased. While pressure caps were considered leak-proof, the results of the soil and water analysis did not clearly show that the technology was less polluting than the vaccum/pressure treatment method. The pollution mitigating capabilities of the technology depended on whether the proper procedures and mitigating practices were observed during and after treatment. The HPSD technology can be commercialized if favorable government policies were implemented
