Abstract

Today, in developing countries like Malaysia, the problem of material waste is a critical concern. There is a recycling model named the Product Recycling Desirability Model was able to boost the recycling rate. However, the model is not applicable to Malaysia because of missing element of material security index. To determine the material security index, a database is needed. There are two dimensions used to develop material security database, which were supply risk and material risk. There are four measures of supply risk, which are scarcity, monopoly supply, political stability and climate change vulnerability. While the four indicators for material risk are Malaysia’s consumption levels, substitutability, global warming potential and total material requirements. Each indicator had its own scoring method for evaluating the security and criticality of the material. Then the materials plotted on material security matrix to determine the most critical material. In this project, critical materials had been identified and assessed where 89 materials were classified as a critical for Malaysia with the five top ranked material are Palladium, Rhodium, Gold, Platinum and Tellurium. The outcome of this project was used in the Product Recycling Desirability Model to assess the desirability index for recycling products. By having the material list, the recycling policies and initiatives can be strategically enforced by the government, including the implementation of Product Recycling Desirability Model, by developing the material security database for the Malaysia’s economy.
