The increasing demand for sustainable alternatives to conventional plastics has propelled the interest in bioplastics. While numerous studies have showcased their environmental advantages, particularly reducing global warming potential and fossil fuel usage, comprehensive reviews on holistic impacts of bioplastics throughout life cycle are scarce. This paper aims fill this gap by critically evaluating sustainability bioplastics, from production disposal. We find that impact is influenced feedstock choices, processing methods, disposal practices. Although intensive agriculture can cause acidification eutrophication as well incomplete biodegradation may lead formation bio-micro/nano-plastics, generally present a lower burden than traditional plastics, evidenced reduced carbon footprint enhanced biodegradability, which contributes decreased plastic waste. Importantly, positively affect soil dynamics, underscoring role promoting agricultural management advocate future Life Cycle Assessment develop inventory database enabling more thorough evaluation impacts. research provides critical insights policymakers viability

Occurrence of microplastics and nanoplastics in aquatic systems, as well water compartments used to produce drinking have become a major concern due their impact on the environment public health. Nanoplastics particular, regard fate removal efficiency treatment plants (DWTP), which ensure quality supply for human consumption been, by far, rarely investigated. This study investigates polystyrene (PS) conventional plant providing 500'000 consumers. For that purpose, pilot-scale DWTP, located within main station, reproducing at reduced scale different processes conditions is used. The results show filtration process through sand granular activated carbon (GAC) filters absence coagulation achieves an overall nanoplastic 88.1%. mainly attributed physical retention adsorption mechanisms. On other hand, it found greatly improves with global equal 99.4%. effective increases considerably from 54.3% 99.2% presence coagulant, indicating most PS are removed during process. higher addition coagulant related surface charge reduction aggregation thus significantly increasing filter media.

Bioengineered microbes for soil health restoration: present status and future

Bioengineered, Год журнала: 2021, Номер 12(2), С. 12839 - 12853

According to the United Nations Environment Programme (UNEP), soil health is declining over decades and it has an adverse impact on human food security. Hence, restoration a need of hour. It known that microorganisms play vital role in remediation pollutants like heavy metals, pesticides, hydrocarbons, etc. However, indigenous microbes have limited capacity degrade these will be slow process. Genetically modified organisms (GMOs) can catalyze degradation process as their altered metabolic pathways lead hypersecretions various biomolecules favor bioremediation This review provides overview application bioengineered for by pollutants. also sheds light challenges using GMOs environmental introduction may affect normal microbial community soil. Since refers potential native survive, possible changes with are discussed. Finally, future prospects engineering applications make fertile healthy been deciphered. With alarming rates loss, treatment fastened greater pace combinatorial efforts unifying GMOs, plant growth-promoting rhizobacteria, other amendments provide effective solution heath ten years ahead.
