ClearIt is still too early to promote biodegradable mulch film on a large scale: A bibliometric analysis
Researchers conducted a bibliometric analysis of studies on biodegradable mulch film as an alternative to conventional plastic mulch in agriculture. The study found that despite growing research interest, significant knowledge gaps remain regarding biodegradation rates in real field conditions and potential ecotoxicity of degradation byproducts. The analysis suggests it is premature to promote large-scale adoption of biodegradable mulch film without further evidence of its environmental safety.
Are mulch biofilms used in agriculture an environmentally friendly solution? - An insight into their biodegradability and ecotoxicity using key organisms in soil ecosystems
Researchers assessed the biodegradation and ecotoxicity of a commercial biodegradable mulch biofilm in soil systems. The study found that while marketed as environmentally friendly alternatives to conventional plastic mulch, biodegradable films did not fully degrade under natural soil conditions as certification standards would predict. The results suggest that more rigorous testing under realistic field conditions is needed before assuming these products are safe for soil ecosystems.
On the quest for novel bio-degradable plastics for agricultural field mulching
This review examined the challenge of developing biodegradable plastic mulch materials suitable for agricultural use, noting that plasticulture consumes about 6.7 million tons of plastic annually, most of which cannot be practically recycled. The authors assessed candidate biodegradable polymers based on their degradation rates in soil, mechanical performance, and cost.

How to quantify the impact biodegradable materials may have?
Researchers at Wageningen examined how to quantify microplastic accumulation in nature to evaluate the impact of biodegradable polymers, noting that a comprehensive, universally applicable methodology is currently lacking. They presented predictive modelling approaches to examine whether biodegradable alternatives can reduce environmental microplastic burdens.
A progress update on the biological effects of biodegradable microplastics on soil and ocean environment: A perfect substitute or new threat?
This review examines whether biodegradable plastics, often marketed as eco-friendly alternatives, actually break down safely in the environment. The evidence shows that biodegradable plastics often fragment into microplastics rather than fully decomposing, and these biodegradable microplastics can harm soil organisms, marine life, and disrupt nutrient cycles. The findings suggest that simply switching to biodegradable plastics may not solve the microplastic pollution problem and could introduce new environmental risks.
Are biodegradable plastics an environmental rip off?
Researchers critically analyzed current technical standards used to certify plastic biodegradability and found that test conditions fail to reflect real-world aquatic and deep-sea environments where most plastic ends up, arguing that existing certifications may be misleading and that standards must be urgently revised to include deep-sea conditions, microplastic formation, and ecotoxicological endpoints.
Methodology development: evaluation of structural, thermal, and mechanical properties of poly(lactic acid)/poly(butylene adipate-co-terephthalate) blends for biodegradable mulch
Researchers developed a methodology for formulating and characterizing biodegradable PLA/PBAT mulch films as alternatives to conventional polyethylene mulch that contributes to microplastic pollution in agriculture. The proposed approach covers scalable formulation, processing, and comprehensive characterization aligned with regulatory guidelines and industry standards for biodegradable mulch performance.
Unravelling the ecological ramifications of biodegradable microplastics in soil environment: A systematic review
Researchers reviewed 85 studies on biodegradable microplastics in soil, finding that when biodegradable plastics fail to fully break down they can disrupt soil structure, nutrient cycling, and microbial life in ways that depend heavily on concentration and plastic type. The review highlights that "biodegradable" plastics are not a simple fix for microplastic pollution in agricultural soils.
Biodegradable plastics: Green hope or greenwashing?
This review examines biodegradable plastics and their limitations, finding that many do not break down effectively under real-world environmental conditions and may still fragment into microplastics. The authors caution that biodegradable plastics should not be viewed as a simple solution to plastic pollution without better standards and end-of-life infrastructure.
Plant stimuli-responsive biodegradable polymers for the use in timed release fertilizer coatings
