dirty diapers can become the ideal substrate for the construction of cover crops. The disposable diapers are a serious problem for the environment because its components are not biodegradable and often end up in landfills. While starting to be valid alternatives to disposable diapers and some companies have emerged as Knowaste dedicated to the recycling of diapers, most consumers still opt for this type of single-use diapers.
Most disposable diapers contain SAP (Super Absorbent Polymers). Chemically, they are particles of sodium polyacrylate to the human eye can be seen as a white powder without smell. This material can absorb up to 30 times its weight in fluid, a property that makes it ideal for use in diapers, sanitary napkins or chemical processes that require water absorption. A diaper, therefore, may contain up to half a liter of urine, making it also a major source of nitrogen.
green roofs, partially or completely covered by plants, are interesting because, among other things, improve the climate of the building, filter air pollutants and rain reduce the overheating of cities, urban and preserve biodiversity act as noise barriers. Plants that live in these green roofs, although they are adapted to extreme conditions, also need a supply of water and nutrients. Hence, the architects of the study Qenep introduced used diapers in one of his projects, because in addition to the SAP are able to accumulate a lot of water that the plant can be consumed over time, are loaded with nitrogen from urea, an essential nutrient for plants.
