Indonesia has approximately 16.8 Mha of degraded lands. These lands have the potential to grow biofuel species to meet the need for energy security, income generation and land restoration. As a promising species Calophyllum inophyllum is suitable to grow in 5.7 Mha of degraded land in Indonesia and could contribute to green energy production and restoration of these degraded lands. During the growing stage, this species can grow up to 1 m in height per year and tolerates to harsh environmental conditions. Its seed provides high levels of non-edible oil, thus making it ideal for biodiesel production. In addition, during the biodiesel production process, its waste and by-products can be used as a raw material in pharmaceuticals and cosmetic industries, and as a compost for soil enrichment. Growing various cash crops with Calophyllum inophyllum as agroforestry can provide extra income to farmers, thus create added value of Calophyllum inophyllum cultivation.
