the current situation of Thai plastic industry and the overview of plastic waste management
in Thailand. The field observations were also done to collect data related to the actual
activity of stakeholder and recheck the secondary data. The questions in questionnaire
differ in each key person and key organizations, and the lists of questions are presented in
Appendix B.
3.5.3 Data analysis for stakeholder analysis
Stakeholders of plastic waste management in Thailand were listed and filled in stakeholder
table (see Table A-11 in Appendix A). Information of each stakeholder was reviewed from
secondary data, and the information from primary data collection was then added more in
stakeholder table. After filling stakeholder table, all parameters were analyzed, and

of plastic wastes, plastic manufactures, recycling technology researches, and laws and
policies. Moreover, the available secondary data in other countries were also searched and

3.6.2 Proposing scenarios
There three different scenarios proposed were set to evaluate the plastic waste management
situation in 2016 following the National Environmental Quality Control Plan in 2012-2016
(MNRE, 2013), the plastic bag taxation research in 2011, and Alternative Energy
