The possibilities for the management of disposable diapers in municipal solid waste have been studied. An in-depth revision of literature about generation, composition and current treatment options for disposable diapers showed that the situation for these wastes is not clearly defined in developed recycling societies. As a promising technology, composting of diapers with source-separated organic fraction of municipal solid waste (OFMSW) was studied at full scale to understand the process performance and the characteristics of the compost obtained when compared with that of composting OFMSW without diapers. The experiments demonstrated that the composting process presented similar trends in terms of evolution of routine parameters (temperature, oxygen content, moisture and organic matter content) and biological activity (measured as respiration index). In relation to the quality of both composts, it can be concluded that both materials were identical in terms of stability, maturity and phytotoxicity and showed no presence of pathogenic micro-organisms. However, compost coming from OFMSW with a 3% of disposable diapers presented a slightly higher level of zinc, which can prevent the use of large amounts of diapers mixed with OFMSW.
已对一次性尿布在城市固体废物管理中的应用可能性进行了研究。对一次性尿布的产生、组成和当前处理选择的深入文献回顾表明，在发达的回收社会中，这些废物的情况并未明确界定。作为一种很有前途的技术，对与城市固体废物的有机部分（OFMSW）进行源头分离的尿布进行了堆肥的全面研究，以了解在不使用尿布的情况下进行 OFMSW 堆肥时，该过程的性能和获得的堆肥的特性。实验表明，堆肥过程在常规参数（温度、含氧量、水分和有机物含量）和生物活性（以呼吸指数衡量）的演变方面呈现出相似的趋势。关于这两种堆肥的质量，可以得出结论，这两种材料在稳定性、成熟度和植物毒性方面完全相同，并且没有存在致病性微生物。然而，由含 3%一次性尿布的 OFMSW 制成的堆肥中锌的含量略高，这可能会阻止大量混合有 OFMSW 的尿布的使用。
