In a sustainable palm oil production the objective is the use of all valuable components of EFB without environmental pollution. Table 1 and 2 show the composition of EFB. They are characterised by a high content of organic matter and plant nutrients, especially potassium but also nitrogen, and a relatively wide C/N ratio. The content of holocellulose is about 70 % and 17 % is lignin (Goenadi et al. 1994).
The alternatives for the use of EFB are beneath fuel as mulch (Singh et al., 1989, Singh 1994) compost, and raw material for pulp and paper industry (Lubis et al., 1994; Goenadi et al., 1994; Guritno et al., 1995).
Composting of EFB is an interesting alternative, because this alternative can reuse not only the mineral plant nutrients, but also the organic matter with the positive impact on soil structure, improving water and air capacity. The nitrogen concentration of EFB is low compared to their carbon concentration, so added N source can be important to induce the micro-organisms growth.
