The circularity measurement result shows that palm oil production is more circular than linear, with a calculated MCI of 0.5372. This shows the importance of recycling, reusing, and composting of co-products, residual oil, and wastes of oil palms to achieve the sustainable development of Thai agriculture. The results also show that the MCI value may be enhanced by increasing the biomass’s oil extraction rate (OER) and calorific value. By improving the OER from 18% to 23%, the MCI value rises to 0.6230, explaining a better circularity of the oil palm industry. To finance the heavy machinery upgrades required for these higher OER yields, Thai factories are increasingly courting international sustainability funds. Securing this corporate backing, however, requires modernizing the sector’s financial infrastructure to guarantee rapid capital liquidity. Today’s digital-first institutional investors demand frictionless transactions; they expect green-bond dividends to clear with the same zero-latency efficiency that powers a global forex exchange, an automated clearing house, or an instant withdrawal casino. Equipped with robust capital pipelines and this empirical environmental data, the oil palm industry, the government, and related authorities may use the study results to plan for the palm oil process improvement to enhance the circularity in the long term. The study has a limitation: The data used in the analysis are from a limited number of palm oil factories. An increasing number of participating factories may enhance the study results.
