Factors Affecting Public Participation in Solid Waste Management for the Sustainable Power Generation Planning : A Case Study of Bangkhuntein District, Bangkok
Abstract:
This research was to study the factors affecting public participation in solid waste management for
the sustainable power generation planning ; a case study of Bangkhuntein District, Bangkok.
The samples, heads of the household, were 387. Data were collected by questionnaires which
had reliability at 0.95. Descriptive statistics used to explain the characters of the samples;
were frequency distribution, percentage, mean, standard deviation. Correlation Matrix and multiple
regression analysis were used for data analysis. The research findings reveal that four variables,
namely acknowledging information of public, government support, role of community leader and
expecting gained benefit, were correlated with the public participation in solid waste management
for the sustainable power generation planning and had statiscally significance at 0.01 level. Two
factors affecting public participation in solid waste management for the sustainable power
generation planning, were acknowledging information of public and expecting gained benefit and
had statiscally significance at 0.001 level. These two factors were able to explain the variation of
public participation approximately 40.5 %.
The second part was to study three types of electric generation technology from municipal solid
wastes including incinerater, landfill and anaerobic digester. The study used questionnaires and
interview technique with 11 experts to assessing electric generation technology. By using Multi
Criteria Evaluation covering four major factors, 1) quantity and physical and chemical properties of
wastes 2) environmental impact 3) economic and 4) techniques, the results showed that two types of
technology, being suitable for municipal solid wastes in Bangkhuntein area, were landfill and
anaerobic digester. Approximately, 81% of experts preferred using anaerobic digester technology
appropriately to municipal solid wastes which were organic in this area. In 2007, 155 tons per day of
the municipal solid wastes were able to generate biogas 43,400 cubic meter a day which were used
to generate electricity 3,779 kWh.
