This review summarizes the bioremediation and phytoremediation technologies proposed so far to detoxify PCB-contaminated sites. A critical analysis about the potential and limits of the PCB pollution treatment strategies by means of plants, fungi and bacteria are elucidated, including the new insights emerged from recent studies on the rhizosphere potential and on the implementation of simultaneous aerobic and anaerobic biodegradation processes. The review describes the biodegradation and phytoremediation processes and elaborates on the environmental variables affecting contaminant degradation rates, summarizing the amendments recommended to enhance PCB degradation. Additionally, issues connected with PCB toxicology, actual field remediation strategies and economical evaluation are discussed.

Per- and polyfluoroalkyl substances (PFAS) are synthetic organofluoride compounds, widely used in industries since the 1950s for their hydrophobic properties. PFAS contamination of soil and water poses significant environmental and public health risks due to their persistence, chemical stability, and resistance to degradation. The Chemical Abstracts Service catalogs approximately 4300 PFAS globally.

Bioplastics, particularly polyhydroxyalkanoates (PHAs), are emerging as promising alternatives to traditional materials due to their biodegradability. This study focuses on the production of PHAs as bioplastics using effluent from hydrogen production in a two-stage Biohythane Pilot Plant, which provides a low-cost substrate. The aim is to optimize production conditions, with Cupriavidus necator TISTR 1335 being used as the PHA producer.

Used engine oil is considered to be one of the high-risk pollutants, and if introduced untreated in the environment, it threatens the whole ecosystem. Therefore, there is a need to find some rapid and efficient methods for the remediation of used engine oil. The present study aimed to isolate indigenous bacterial strains having the capability to degrade used engine oil.

Faced with all kinds of serious ecological and environmental protection problems in today's society, development must take the sustainable and green road. Nanocellulose aerogels with the advantages of wide resource of raw materials, low cost, good biocompatibility and biodegradation, are good thermal and sound insulation materials. Herein, a versatile composite aerogel with good thermal stability and heat-insulating property was prepared by freeze-drying method using cellulose nanocrystals (CNCs), waterborne polyurethane (WPU) and sepiolite (SEP) as substrates.
