This research paper aims to investigate the impediments faced by innovation-driven enterprises in Thailand and to explore the current measures, policies, and mechanisms related to innovation-driven enterprises (IDEs)’ development both domestically and internationally. The study encompasses a comprehensive approach, including an analysis of an innovation entrepreneur database comprising 320 investors and 883 IDEs. Moreover, semi-structure in-depth interviews were conducted with three investors, twenty-two IDEs’ founders, eight executives, and experts from various sectors, including government, university incubators, and the private sector in Thailand. Through this multifaceted investigation, this paper sheds light on the key factors that hinder the success of IDEs in Thailand, which primarily revolve around the quality of entrepreneurs (Team), Product and Market Fit, and Support. These factors collectively impact the depth of knowledge, business incubation, acceleration programs, and the effectiveness of laws, measures, and policies in supporting innovation capability development within IDEs. In addition, this paper presents a framework for Thailand’s IDEs hub, facilitating the connection between the university's innovation and entrepreneurship ecosystem with public and private stakeholders. This framework serves as a mechanism to address the identified hindrances and foster a conducive environment for IDEs development. To address the obstacles, this paper proposes three crucial strategies, namely, (1) talent management, (2) ease of doing scaleup, and (3) availability of funding. These strategies are envisioned to counteract the identified challenges and can be effectively implemented through an operating model and practical working procedures tailored to suit the specific context of Thailand.

Although stakeholder collaboration is key for sustainable development of tourism in small islands, research on its determinants is only emerging. The lack of empirical studies hampers an understanding of how effective stakeholder partnerships for sustainability in small tourism islands can be formed and sustained. To partially address this knowledge gap, this study explores stakeholder collaboration for solid waste management in the island of Koh Phayam, Thailand, from the perspective of stakeholder theory, social capital and proximity effect. Semi-structured interviews (n = 26) reveal a lack of understanding of collaboration benefits alongside leadership and reciprocity among stakeholders. However, due to geographical proximity, the level of stakeholder trust in each other is significant, thus indicating potential for future successful partnerships. For these partnerships to become effective, a system of financial incentives for stakeholders to separate and recycle solid waste in situ should be designed. To improve stakeholder communication and reciprocity, capacity building workshops and round tables can be organised. Municipal authorities should lead on solid waste management, and a steering committee comprising the representatives of all other stakeholders needs to be established to oversee the work of municipal authorities. Lastly, the feasibility of setting private public partnerships for solid waste management in Koh Phayam should be considered given the significant extent of knowledge and trust among local stakeholders. External stakeholders, such as farmers, can be involved in management of organic waste, thus extending the scope of partnerships for sustainability beyond the island.

In alignment with the United Nations’ Sustainable Development Goals (SDGs) 12 (Responsible Consumption and Production) and 13 (Climate Action), this research explores the sustainable valorization of mangosteen peels into mangosteen peel powder (MPP), a value-added product with pharmaceutical properties. Mangosteen peels are an abundant agricultural waste in Thailand. This study evaluates six MPP production schemes, each employing different drying methods. Life Cycle Assessment (LCA) is utilized to assess the global warming potential (GWP) of these schemes, and the quality of the MPP produced is also compared. The results show that a combination of frozen storage and freeze-drying (scheme 4) has the highest GWP (1091.897 kgCO2eq) due to substantial electricity usage, whereas a combination of frozen storage and sun-drying (scheme 5) has the lowest GWP (0.031 kgCO2eq) but is prone to microbial contamination. Frozen storage without coarse grinding, combined with hot-air drying (scheme 6), is identified as the optimal scheme in terms of GWP (11.236 kgCO2eq) and product quality. Due to the lack of an onsite hot-air-drying facility, two transportation strategies are integrated into scheme 6 for scenarios A and B. These transportation strategies include transporting mangosteen peels from orchards to a facility in another province or transporting a mobile hot-air-drying unit to the orchards. The analysis indicates that scenario B is more favorable both operationally and environmentally, due to its lower emissions. This research is the first to comparatively assess the GWP of different MPP production schemes using LCA. Furthermore, it aligns with the growing trend in international trade which places greater emphasis on environmentally friendly production processes.

During the early periods of civilization, solid waste was conveniently collected transported and disposed because of the low number of population. However, waste generation is expected to increase becasue of rapid population growth and consequently shows an increase in solid waste collection, transportation, and disposal. Waste transportation planning is a difficult task due to the issues of the increasing numbers of garbage vehicles and the fluctuation of fuel prices as well as the cost-effectiveness and health and environmental impacts. An unsustainable waste collection and transportation is heading towards a variety of indirect human health impacts. Accordingly, the vehicle routing problem (VRP) plays a significant role in the field of waste collection and transportation system. This study compares three different Life Cycle Assessment (LCA approaches for the waste transport in Ladkrabang, Bangkok, Thailand. The three scenarios are modelled using GaBi 7 software tool and results are presented based on the CML 2001. The assessment outcomes indicated that the routing optimization with diesel and electric garbage trucks could significantly reduce the GWP impact by 8.51% and 66.44% compared to the baseline scenario, respectively.

Global warming is an increase of average temperature in the atmosphere, which causes adverse effects on the environment. Carbon dioxide (CO2) from transportation sector is one of the main contributors of the overall greenhouse gases (GHG). To cope with this issue, electric car services are increasingly seen as popular alternative modes of green transportation especially for urban cities as it is more flexible, more environmentally-friendly, and less expensive than the use of conventional vehicles. The study analyses and compare the hypothetical electric car systems from airport transportation services. Center of Environmental Science of Leiden University (CML) 2001, the Life Cycle Impact Assessment (LCIA) method, is applied to convert life cycle inventory data into environmental impacts. The observed results showed that the electric shuttle bus had the highest impact in global warming potential (GWP) compared to other transportation types. Alternatively, this Life Cycle Assessment (LCA) study that evaluated different transportations provided important information for decision makers on quantifying the differences between each scenario.
