Value chain analysis for green productivity improvement in the natural rubber supply chain: a case study

The main objective of this research was to map and to analyze green productivity of a natural rubber supply chain and formulate scenarios for increasing its green productivity level. The case studies were conducted in private enterprises engaged in natural rubber plantation and processing. Material flow analysis was performed using the green material flow map to analyze the seven sources of green wastes. The best strategy for green productivity improvement was determined by using the Analytic Hierarchy Process (AHP). The performance of green productivity improvement strategies was then assessed as future GPI (Green Productivity Index) and compared with current GPI. Results of this research have shown that the natural rubber cultivation combined with latex production improvement and waste minimization was the best green productivity improvement strategy. The best selected strategy for the production process was reusing the processing water.
