Composting is a good recycling method to fully utilise all the organic wastes present in kitchen waste due to its high nutritious matter within the waste. In this present study, the optimised mixture proportions of kitchen waste containing vegetable scraps (V), fish processing waste (F) and newspaper (N) or onion peels (O) were determined by applying the simplex-centroid mixture design method to achieve the desired initial moisture content and carbon-to-nitrogen (CN) ratio for effective composting process. The best mixture was at 48.5% V, 17.7% F and 33.7% N for blends with newspaper while for blends with onion peels, the mixture proportion was 44.0% V, 19.7% F and 36.2% O. The predicted responses from these mixture proportions fall in the acceptable limits of moisture content of 50% to 65% and CN ratio of 20-40 and were also validated experimentally.
堆肥是一种很好的回收方法,可以充分利用厨房废物中存在的所有有机废物,因为废物中含有很高的营养物质。在本研究中,通过应用单纯形质心混合设计方法,确定了含有蔬菜残渣(V)、鱼加工废物(F)和报纸(N)或洋葱皮(O)的厨房废物的最佳混合比例,以达到所需的初始水分含量和碳氮比(CN),从而实现有效的堆肥过程。对于与报纸混合的混合物,最佳比例为 48.5%V、17.7%F 和 33.7%N;而对于与洋葱皮混合的混合物,最佳比例为 44.0%V、19.7%F 和 36.2%O。这些混合比例的预测响应值落在水分含量为 50%至 65%和 CN 比为 20-40 的可接受范围内,并且也通过实验进行了验证。
