Composting System

composting

The palm oil wastes, including empty fruit bunch (EFB), decanter cake, boiler ash and palm oil mill effluent (POME) were mixed together using a special formulation and allowed to undergo fermentationfor a period of 45 days to produce superior quality palm-based living organic fertilizer. During the fermentation process, a scientifically formulated biological cocktail,Bio-Plus Activator (BPA) was added to enhance the decomposition of palm oil wastes. BPA consists of 25 “super-strain” microbes that work together to transform and mobilize nutrient elements in the organic fertilizer into readily assimilable forms.

Throughout the decomposition period, temperature and moisture content of the compost pile were closely monitored. Addition of POME and turning process were carried out when these two parameters fall below the average level. The fertilizer quality (nitrogen, phosphorus, potassium, moisture, pH, total organic matter and total organic carbon contents) was analysed by laboratory with ISO standard. Once the fertilizer quality is satisfactory, they will be packaged, stored and ready to be distributed.

Our current composting system is efficiently achieving the following performance as shown in Table 1.
