Baby diaper companies are increasingly using biodegradable materials, but they do not always perform as well as non-renewable plastics in terms of:
Absorbency
Plant-derived fibers and gels absorb liquid well, but may not retain as much volume or dry as quickly as synthetic options. This affects how long a diaper can be worn before changing.
Breathability
Biodegradable materials are often thicker and less breathable than extremely thin plastics, which can increase warmth and lead to skin irritation in hot/humid climates.
Fit & Leak Prevention
Non-renewable plastics result in thinner diaper cores that contour closely to babies’ bodies for excellent leakage protection. Natural fibers are not as precision-engineered.
Strength & Durability
Plastics stand up better to stress without degrading as quickly, resulting in diapers that maintain integrity longer during wear and wash cycles. Plant materials can deteriorate faster.
Scent Control
Synthetic absorbents and barriers are better at masking odors than biodegradables, which may transmit smells more readily.
Cost
Producing diapers from renewable resources usually increases manufacturing costs compared to oil-based plastics, which are then passed on to consumers.
However, biodegradable options are improving and many parents find their eco-friendliness worthwhile for occasional or overnight use. Performance continues to close the gap with petrochemical diapers.
