Waste composting is becoming a key element of integrated waste management. Composting has a number of advantages, including economic benefits, improvement of soil properties through the use of compost, reduction in the use of chemical fertilisers, and minimization of environmental pollution. Composting on a landfill surface appears to be an economical solution that can help close the waste loop and material cycle. In this study, a composting plant located on a landfill surface was analysed. The main objective of the research was to identify the species of plants growing in the organic fraction of municipal solid waste in temporary storage, in the composting plant, and in maturing compost located in a reclaimed plot at the landfill site. During monitoring, 88 plant species were identified altogether. It was observed that compost can become a source of weed infestation. To control the presence of weeds in the compost, basic principles of composting are to be followed to reduce the quantity of weed seeds. The thermophilic phase must occur to reduce the viability of seeds in the input materials and sufficient moisture must be ensured during the composting process. When these principles are strictly observed and the stored compost is maintained without vegetation, the supply of seeds in the compost will be low, and the undesirable spread of plant species to adjacent areas will be controlled. The results showed that the use of the obtained compost did not result in the propagation of weed species. This study demonstrates that composting on a reclaimed landfill offers various advantages such as a closed waste management cycle, coverage of the active landfill body, and fertilisation of the reclaimed part of the landfill.
垃圾堆肥正在成为综合废物管理的关键要素。堆肥有许多优点，包括经济效益、通过使用堆肥改善土壤性质、减少化学肥料的使用以及最小化环境污染。在垃圾填埋场表面进行堆肥似乎是一种经济的解决方案，可以帮助封闭废物循环和物质循环。在本研究中，分析了位于垃圾填埋场表面的一个堆肥厂。研究的主要目的是确定在临时储存、堆肥厂和位于垃圾填埋场回收区域的成熟堆肥中的城市固体废物有机部分中生长的植物种类。在监测过程中，总共确定了 88 种植物。观察到堆肥可能成为杂草滋生的来源。为了控制堆肥中的杂草，必须遵循堆肥的基本原则，以减少杂草种子的数量。必须发生高温阶段，以降低输入材料中种子的活力，并确保堆肥过程中有足够的水分。当严格遵守这些原则并保持储存的堆肥没有植被时，堆肥中的种子供应将减少，并且可以控制植物物种向相邻区域的不良传播。结果表明，使用获得的堆肥不会导致杂草物种的繁殖。本研究表明，在回收的垃圾填埋场上进行堆肥具有各种优点，例如封闭的废物管理循环、覆盖活动的垃圾填埋体以及对垃圾填埋场回收部分的施肥。
