Abstract
This study aims to examine the factors affecting the management of biogas
production from the wastewater produced by natural rubber processing at community
level and to develop a management model. The methodologies consist of a literature
review on the factors affecting biogas management and the sites studies based on
structural interviews with three rubber sheet production cooperatives in Songkhla
Province. The data are summarized to find the key factors and criteria. These factors
and criteria were ranked using the Analytical Hierarchy Process (AHP) to establish a
management model. The initial model was then tested on six natural rubber processing
companies including the Wangluang Cooperative Rubber Production, Wangkiri
Cooperative Rubber Production, Baan Nong-Khla Cooperative Rubber Production,
Wangcharearn Cooperative of Agriculture, Chiang Rai Rubber Center Co. Ltd., and
the LaanNa Rubber Co. Ltd. As a result, five key factors were found including
environmental factors, social factors, health impact factors, economic factors and
technological factors, respectively. The results from the test model showed that there
were 0.791 points for the two sites of successful biogas production that were
considered to have good management in the biogas production plants. Meanwhile,
0.388-0.390 points showed a failure in biogas production. Moreover, 0.101 points
were given to those companies for which details of biogas production were not be
obtained. Practical guidelines for a management model for biogas production from the
wastewater produced by natural rubber processing at the community level were developed as follows: 1) identifying the environmental problems, 2) building the
social cooperation, 3) sanitation improvement, 4) economic analysis, and 5)
considerations relating to biogas technology. The relevant authorities should evaluate
biogas production from the wastewater produced by natural rubber processing using
this model to avoid the failure of biogas production at other sites. In addition, the
successful sites of biogas production from wastewater produced by natural rubber
processing should provide training to the employees of biogas production companies
to increase the potential of biogas production at new sites and to avoid failure at those
sites.
