Spatiotemporal Dynamics of Microbial Communities Colonizing Plastic Tent Fabrics in a Tropical Environment
<p>Plastic polymers provide immense utility in almost all industries. However, their mass production and persistence in natural ecosystems has resulted in a significant accumulation of plastic waste in our biosphere. To protect structurally important plastic products from degradation as well as …

Characterization of Novel Urethanases and a Commercial Cutinase for the Degradation of Polyurethane
Every year, 460 metric tons of plastic are produced, yet only 10% is recycled. Due to the chemical inertness and durability of plastic materials, recycling techniques employ combustion and melting, exacerbating the global climate crisis by releasing greenhouse gases. Polyurethane (PU) is the second …

Characterisation and plastic-degrading potential of plastisphere-associated microorganisms
The versatility and affordability of plastics have contributed to their largely unrestricted production, increasing from two million tons (Mt) in 1950 to roughly 400 Mt per annum in 2022. Consequently, plastic waste is accumulating in the environment, where its degradation is slow, impacting …

Abiotic and Biotic Polymer Degradation to Inform Sustainable Design
As global plastic production continues to rise, understanding environmental processes governing plastic degradation is crucial to inform the sustainable design of polymers. This thesis is structured into three chapters, each addressing critical aspects of polymer degradation: In the first chapter, …

Porous Carbon Fiber Functionalization and Thermochemical Degradation of Polystyrene-based Plastics for Resource Recovery
… and the environmental issues caused by plastic waste accumulation. First, porous carbon fiber (PCF) derived from PAN-based block copolymer was synthesized and functionalized for the extraction of REEs. Second, the thermochemical degradation of PS and PS-based engineering plastic into …

Promoting pulp and paper mill material circularity: functionalised organic-inorganic cellulosic mulch films
… prevent weed growth, respectively. However, microplastics remaining from poorly biodegradable mulch films, and the release of typical mulch film UV-absorbent additives bioaccumulate, which harms the environment. Concurrently, paper and pulp mills (PPMs) generate substantial amounts of inorganic …

Multi-omic Investigation of Plastic-Associated Microbes: Bioinformatic Insights into Plastic Biodegradation and Novel Degrading Genes Across Environments
Synthetic plastics and their resulting waste are ubiquitous across the planet, from the Arctic to the tropics. Despite increasing efforts to understand the fate and transport of these plastics, their fate and impact on the environment and public health are still not well understood. To better …

Studies of microplastics present in sewage sludge, effects on amended agricultural soils
Intensive plastic usage aims at making life easier, with the highest value and the lowest input of resources. Global environmental alarm and social sensitivity revealed that microplastics (MPs) are the most notable type of plastic degradation and pollution that has attracted much attention among …
