以园林废弃物、污水污泥和木灰为原料，在一年中的不同时间生产两种堆肥，对其作为观赏植物基质的使用进行了评价。这两种堆肥的成熟和无植物毒性，以及没有大肠杆菌，首先通过使用实验室程序和快速检测试剂盒得到证实。以矮牵牛（Petunia sp.）和万寿菊（Tagetes sp.）两种观赏植物为试验材料，对堆肥作为植物基质的适宜性进行了评价。将含25%、50%和75%酸性泥炭苔藓的堆肥及其混合物的性能与商业通用基质的性能进行了比较。在堆肥中加入泥炭可以改善一些物理和化学性质。盆栽试验结果表明，在试验条件下，绿色废弃物堆肥不需要添加其他组分，适合作为植物基质使用；这似乎是利用研究中所考虑的城市废物类型的有效方法。
Two composts produced at different times of the year from garden waste, sewage sludge and wood ash were evaluated for use as ornamental plant substrates. The maturity and lack of phytotoxicity of both composts, as well as the absence of E. coli, were first confirmed by use of laboratory procedures and rapid test kits. A greenhouse experiment was then carried out with two ornamental species, Petunia sp. and Tagetes sp., to evaluate the suitability of the composts as plant substrates. The performance of the composts as well as mixtures of each with 25, 50 and 75% acid peat moss was compared with that of a commercial universal substrate. Addition of the peat to the composts improved some of the physical and chemical properties. However, the results of the pot experiments indicated that under the experimental conditions used, the compost produced from green waste was suitable for use as a plant substrate, without the need for addition of other components; this appears to be an effective way of utilizing the type of urban waste considered in the study.
