| dc.description | New palm oil mill processes are characterised by advanced oil separation technologies with zero dilution water (ECO-D System for example) and continuous sterilisation of the FFB. These processes have a deep impact on the amount and composition of waste water (POME). Compared to conventional palm oil mills the total amount of POME can be reduced from 0.65 m/ton FFB to 0.45 m/ton (conventional sterilisation and zero dilution water) and 0.25 m/ton (continuous sterilisation and zero dilution water). These changes influence the treatment processes and its cost significantly. One process for the EFB and POME utilization which can fulfil the demand of a sustainable palm oil production is the combined composting of both of the materials. The composting process is used also for biological drying of the POME. The final product of the process is compost or mulch which unifies the nutrients of both in one product. The POME can be used also for biogas production (in fixed bed reactors for POME with low dry matter content and in totally mixed reactors for ECO-D biomass) before composting. The investment cost and profitability of the composting and fermentation process is calculated in detail based on data from practise in Indonesia. The new developments of processes in palm oil mills can reduce the cost for the waste and waste water treatment up to 35 %. The benefits from biogas production and composting are the energy production, saved POME treatment cost in pond systems, total utilisation of the POME nutrients, reduced cost for the EFB transport and utilisation, higher FFB yields and from CDM. | |
