Abstract

Empty fruit bunches and palm oil mill effluent are the major and bulky by-products in palm oil mill after extraction of palm oil, both facing practical difficulties in direct soil application. In this experiment, the objective was to standardise an efficient and ecofriendly technique of utilising the nutrient potential of palm oil mill by-products for nutrient recycling. Bunch waste was mixed with raw effluent and digested effluent with and without urea as starter. Both were mixed based on the proportionate availability of the residues from the palm oil mill. A combination of digested slurry from a biogas plant and bunch wastes took only 90 days for maturity of compost whereas the fresh palm oil mill effluent (POME) mixed with bunch waste took 150 days. The final compost was rich in both nitrogen and potassium, for which the palm requirement also is high. Hence the nutrient potential of these by-products can be exploited in an integrated nutrient management approach in oil palm plantations. The nutrients recovered from compost expected from the by-products from a hectare of plantation could meet almost 30 per cent requirement of nitrogen and the full requirement of potassium. The biogas produced during the process is an added advantage of this technique which can be utilised as a fuel source in the mill. Keywords: Biological oxygen demand, composting, empty fruit bunches, nutrient recycling, oil palm, palm oil mill effluent.

空果束和棕榈油厂废水的养分回收-一种共同堆肥技术
空果束和棕榈油厂废水是棕榈油厂提取棕榈油后的主要副产物,它们在直接土壤应用方面都面临着实际困难。在这项实验中,目的是标准化一种有效和环保的技术,利用棕榈油厂副产品的营养潜力进行营养循环。将束状废液与原液和消化废液混合,以尿素和不含尿素为发酵剂。两者都是根据棕榈油厂残留物的比例进行混合的。沼气厂的消化浆液和堆废物的组合只需要90天就能使堆肥成熟,而棕榈油厂的新鲜废水(POME)与堆废物混合需要150天。最终的堆肥富含氮和钾,对棕榈的需求量也很高。因此,这些副产品的营养潜力可以在油棕种植园的综合营养管理方法中加以利用。从一公顷种植园的副产品堆肥中回收的养分可以满足几乎30%的氮需求和钾的全部需求。在此过程中产生的沼气是该技术的一个额外优势,它可以用作磨内的燃料来源。关键词:生物需氧量,堆肥,空果串,养分回收,油棕,棕榈油厂废水。
