利用油棕废弃物，特别是空果串（EFB），叶子和树干作为堆肥，现在越来越受到研究人员的关注。目前，这些有机废料尚未在农业上或工业上大规模地充分利用以生产有用的副产品。在马来西亚，另一种需要妥善处理的有机废物是污水污泥。共同堆肥这些废物材料可以潜在地将这些废物转化为增值产品。本研究的目的是确定最佳配方使用油棕废料和污水污泥生产堆肥材料用作盆栽媒体在园艺。在温室中使用聚苯乙烯箱进行不同油棕废弃物与污水污泥的堆肥。将切碎的油棕废弃物（EFB、叶子和树干）与污水污泥以3种不同的比例（1：0、3：1和4：1的比例）混合，并调节至60%的含水量。从油棕废弃物堆肥过程中的温度、C/N、NH 4 + -N和NO3- - N + NO2- -N的变化规律来看，油棕废弃物堆肥过程中，EFB、油棕叶片和油棕树干的堆肥效果相似，但由于堆肥体积小，热量散失，温度不能维持在45 ℃以上。结果表明，油棕树干与污泥按4：1的比例混合后，其质地不紧不硬，养分含量高（N2.05%，P0.640%，K1.39%，Ca0.705%，Mg0.229%，pH6.2），C/N比低（19.
The use of oil palm wastes, particularly the empty fruit bunch (EFB), frond and trunk as compost are now receiving greater attention by researchers. Currently, these organic waste materials have not been fully utilized on a large scale, either agriculturally or industrially, for manufacture of useful by-products. Another organic waste that needs to be appropriately disposed of in Malaysia is the sewage sludge. Co-composting these waste materials could potentially convert these wastes into value added product. The objective of this study was to determine the best formulation using oil palm wastes and sewage sludge in producing a composted material to be used as a potting media in horticulture. Composting different oil palm wastes with sewage sludge was carried out in the glasshouse using a polystyrene box. Shredded oil palm wastes (EFB, frond and trunk) were mixed with sewage sludge in 3 different ratios (1:0, 3:1 and 4:1 ratio) and adjusted to 60% moisture content. Based on the temperature, C/N, NH4+ -N and NO3- - N + NO2- -N patterns of the oil palm wastes added with sludge during composting, the EFB, frond and trunk added with sludge composts seemed to perform similarly.However, due to the small volume of compost, the temperature did not sustain > 45oC because of dissipation of the heat. Oil palm trunk with sewage sludge at 4:1 ratio was found to be the most optimum compost as potting media for ornamental plants because of its texture suitable for potting media, not stringent or stiff, had high nutrient contents (2.05 % N, 0.640 % P, 1.39 % K, 0.705 % Ca, 0.229% Mg), pH 6.2 and low C/N ratio, 19.
