However, some additional concerns regarding the decomposition of disposable diapers and resulting by-products must be considered. However, wood pulp used in disposable diapers comes from tree farms operating for this purpose rather than forests or woodlands. Questions concerning the completeness of decomposition of both sections of the chemical plastic units in diapers exist. Another potential problem could be leachate, primarily from older landfills, entering ground water supplies. Viruses excreted in human feces could pose health problems long term.
Biodegradable diapers are one option for parents.
They are made from a cornstarch base and, when acted on by bacteria, more rapidly decompose than conventional disposable diapers. The process requires oxygen and water, however, often lacking in landfill operations. Biodegradable diapers may have more potential for composting uses than to address landfill concerns. Nevertheless, neither the quantity of solid waste contributed by diapers nor the potential spread of infection are eliminated with the biodegradable product. Although disposable diapers pose environmental concerns from a solid waste perspective, cloth diapers raise concerns regarding air and water pollution.
