Effect of polylactic acid microplastics on soil properties, soil microbials and plant growth
Researchers tested whether microplastics from biodegradable polylactic acid plastic, often proposed as an eco-friendly alternative to conventional plastic, affect soil health and plant growth. High concentrations of these biodegradable microplastics reduced soil pH, altered the ratio of carbon to nitrogen, decreased plant growth, and shifted soil microbial communities. The study suggests that even biodegradable plastics can negatively affect agricultural ecosystems when they break down into microplastic-sized particles.
Enhancing microplastics biodegradation during composting using livestock manure biochar
Researchers tested whether adding livestock manure biochar to composting systems could enhance the breakdown of biodegradable microplastics.

Researchers investigated how biodegradable polylactic acid microplastics affect dissolved organic matter in three different types of paddy soil. They found that the microplastics altered the molecular composition of organic matter in soil-specific ways, with some soils showing increased humic substances and others showing more protein-like compounds. The study highlights that even biodegradable plastics can change soil chemistry, and the effects vary depending on soil type.

Researchers examined how soil moisture levels affect the degradation of biodegradable poly(lactic acid) microplastics and their influence on soil organic carbon decomposition.

They found that biochar significantly improved microplastic retention in the soil, and experimented with different soil-biochar mixing configurations to optimize performance. The study suggests that biochar amendments could be a practical strategy for reducing microplastic migration through agricultural soils.

Researchers investigated how dissolved organic matter from natural sources versus biochar affects the breakdown of biodegradable polylactic acid (PLA) microplastics in sunlight. Naturally sourced organic matter accelerated PLA degradation nearly twice as much as biochar-derived matter by generating more reactive oxygen species, suggesting that the type of organic matter in a waterway significantly influences whether biodegradable plastics actually break down.
Mineralization and microbial utilization of poly(lactic acid) microplastic in soil
Researchers tracked how polylactic acid (PLA) microplastics, a common biodegradable plastic, actually break down in different agricultural soils.
