Abstract Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review sources, formation, occurrence, toxicity and remediation methods microplastics. We distinguish ocean-based land-based sources Microplastics have been found biological samples such as faeces, sputum, saliva, blood placenta. Cancer, intestinal, pulmonary, cardiovascular, infectious inflammatory diseases are induced or mediated by exposure during pregnancy maternal period also discussed. Remediation include coagulation, membrane bioreactors, sand filtration, adsorption, photocatalytic degradation, electrocoagulation magnetic separation. Control strategies comprise reducing plastic usage, behavioural change, using biodegradable plastics. Global production has risen dramatically over past 70 years reach 359 million tonnes. China world's top producer, contributing 17.5% global production, while Turkey generates waste Mediterranean region, at 144 tonnes per day. 75% marine waste, with responsible 80–90% pollution, account only 10–20%. induce toxic effects on humans animals, cytotoxicity, immune response, oxidative stress, barrier attributes, genotoxicity, even minimal dosages 10 μg/mL. Ingestion animals results alterations gastrointestinal tract physiology, system depression, differential gene expression, growth inhibition. Furthermore, bioaccumulation tissues aquatic organisms can adverse ecosystem, potential transmission birds. Changing individual behaviours governmental actions, implementing bans, taxes, pricing carrier bags, significantly reduced consumption 8–85% various countries worldwide. The microplastic minimisation approach follows an upside-down pyramid, starting prevention, followed reducing, reusing, recycling, recovering, ending disposal least preferable option.

Recent advances and challenges of inter-disciplinary biomass valorization by integrating hydrothermal and biological techniques

Renewable and Sustainable Energy Reviews, Journal Year: 2020, Volume and Issue: 135, P. 110370 - 110370

Published: Sept. 28, 2020

Biomass valorization for the production of various value-added biochemicals and biofuels plays a significant role in modern biorefineries/bioenergy towards climate neutrality future. Among developed techniques biorefining, hydrothermal biological treatments have been demonstrated to valorize raw biomass materials or upgrade biorefinery intermediate products afford respectably desired product yields. From perspective both green chemistry circular bioeconomy, whether inter-disciplinary approach could achieve complete with balanced energy extra profits remains questionable. This review is presented provide an overview opportunities combining valorization. Combinations including (1) pretreatment followed by (such as enzymatic hydrolysis, fermentation, anaerobic digestion, composting) (2) substrates generated from hydrolysis pretreated food waste, digestion produced digestate) biochar, biocrude syngas are comprehensively reviewed. The recent advances regarding treatment conditions, synergies between techniques, optimal performances summarized compared. Assessment balance economic feasibility different integrated options reported previous studies also Finally, challenges perspectives advancing toward concluded.
