PE Mulch vs. Biodegradable Mulch — A Practical Comparison for Cost-Conscious Farmers

As the agricultural industry shifts toward sustainability, many growers find themselves weighing the pros and cons of traditional PE mulch versus emerging biodegradable alternatives. While biodegradable mulch films offer clear environmental benefits, PE mulch remains the most cost-effective choice for the majority of commercial farming operations — and here’s why.

Cost comparison. PE mulch films are significantly more affordable, with prices ranging from $1 to $1.5 per kilogram, whereas biodegradable alternatives such as PLA and PBAT cost $3 to $7.5 per kilogram. For large-scale farmers, this price difference translates into substantial annual savings.

Performance and durability. PE films are known for their durability and effectiveness, reliably improving crop yields while withstanding the full growing season without premature degradation. Biodegradable films, by contrast, face challenges such as variable degradation rates — some degrade too quickly, failing to provide season-long protection, while others degrade incompletely. A recent study also warns that biodegradable mulch may not always disappear as expected, with degradation byproducts potentially accumulating in the root zone.

End-of-life considerations. While PE mulch does require removal and disposal at the end of the season — typically via landfilling or incineration — the removal cost is often offset by the lower initial purchase price. Biodegradable mulch eliminates removal costs but comes with a much higher upfront price tag.

The bottom line. From an economic perspective, PE mulch delivers the highest net benefits, primarily due to its low market price and consistently high yields. For farmers in price-sensitive markets — particularly in Asia, Africa, and South America — PE mulch remains the practical, proven choice.
