Evaluation of Plastic Waste Management in Thailand Using Material ...

of them. For example, one individual waste generator may not seem to be as
important as policy makers or recyclers, but can cause high effects/influence on the
plastic waste management by generating reckless amount of plastic waste, not
participating in source separation and recycling activities.
Group D: Stakeholders with low importance and low influence are unlikely to be
the direct subject of plastic waste management schemes, but can help in
information sharing and raising awareness hence supporting the plastic waste
management strategies and goals. NGOs normally fall under this Group.
4.4.3 Roles and opinions of stakeholders
Identification of roles and their respective opinions have great influence on overall plastic
waste management. Some stakeholders in Figure 4.37 who were interviewed are classified
into five components/processes of plastic waste management: plastic manufacturing,
plastic consumption, waste collection and transportation, recycling, and waste disposal.
Plastic Manufacturing Stakeholders
These stakeholders are the plastic producing organizations/companies. Not only the actual
plastic manufacturers, but the technology providers such as Thai Plastic industries
association (TPIA) fall under this category. Stakeholders like TPIA supports the plastic
manufacturing factories by providing technology knowledge, product designs, markets,
information sharing, and producer networks. Similarly, Thai Bioplastics Industry
Association (TBIA) and Plastic Institute of Thailand (PIT) provides similar support to the
plastic manufactures. TBIA only focuses on the biodegradable plastic products and
producers.
The petrochemical industries who supply the plastic resins (raw materials) to plastic
converters and are the members of Petroleum Institute of Thailand (PTIT) are also the
stakeholders in this group. PTIT is the information sharing stakeholder for plastic waste
management in Thailand because it collects the information from plastic industry and
presents the petrochemical consumption and plastic production of plastic industry.
Department of industrial Works (DIW) and Department of Industrial Promotion (DIP)
support the Public-Private sector institution and plastic companies. The environmental
issues from plastic industry are control by DIW, while, DIP provides funds and markets for
plastic industries including the promotion of investment in both of country and foreign
countries.
Office of Industrial Economics (OIE) is an information sharing stakeholder who shares the
plastic industry statistic and evaluates economic trends of plastic industry. Plastic
Intelligence Unit (PIU) is under OIE and PTIT. It presents information on Thai and world
plastic production such as plastic knowledge and technology, prices of plastic resins,
import-export statistics and plastic production data base.
PIT stated that the plastic industry should label seven codes of recyclable plastics on
plastic products. These codes will make people separate plastic wastes easily. The green
production and green products are the related projects of industrial sector to save the
environment. The biodegradable plastics will become the new issue of plastic waste
management because there are TBIA and NIA which are studying the possible production
