Co-composting of palm oil wastewater sludge and biosolids

The present study deals with the co-composting of palm oil wastewater sludge (OS) and biosolids (BS) as a possible environmental friendly alternative to handle these wastes. Five laboratory scale composters, each containing 5 kg soil spiked with 10 % OS (mass basis) were used. Shredded empty fruit b...
