“…In Romania, wastewater generated by urban communities is poorly treated by outdated wastewater treatment plants (WWTPs), with primary and secondary stage treatments, and there is a poor connection to the sewage system in smaller urban areas or villages [26]. Additionally, industrial plants with their WWTPs are additional water pollution sources for nearby water bodies, where in effluents are discharged [27]. Consumption of water resources without proper sanitation facilities and wastewater treatment plants is a major environmental threat particularly in rural areas where drinking water sources are still reliant on wells [28].…”

This paper reveals the linear economy contribution to resource degradation and environmental pollution in eastern Romania that could further feed environmental crimes and conflicts, such as in the Pungesti shale gas case. Preservation of material and water resources in the region is required through various circular mechanisms under a cross-sectoral approach including solid waste as a material resource for industry and agriculture; wastewater treatment and water reuse; composting and organic agriculture; and using renewables. Six non-conflictual sustainable alternative routes related to circular economy mechanisms, water preservation, and to the clean energy transition are proposed in this paper, which are further examined through key statistics and indicators, current best practices, and local development pathways in both urban and rural communities.

“…Clean water is strongly needed for humanity, animals and plants on a planet with more and more diminishing natural water resources. Society has learned that for prevention of disease and reduction of environmental pollution levels, all wastewater produced must be treated and even reused/recycled to save fresh water supplies [ 1 , 2 , 3 ].…”

Hydrogel Based on Tricarboxi-Cellulose and Poly(Vinyl Alcohol) Used as Biosorbent for Cobalt Ions Retention

A biomaterial based on poly(vinyl alcohol) reticulated with tricarboxi-cellulose obtained by TEMPO oxidation (OxC25) was used as a new biosorbent for Co(II) ions retention from aqueous solutions. The biosorption process of Co(II) ions was studied while mainly considering the operational factors that can influence it (i.e., biosorbent concentration, pH of the aqueous media, temperature and contact time of the phases). The maximum adsorption capacity was 181.82 mg/g, with the biosorption well fitted by the Langmuir model. The kinetic modeling of the biosorption process was based on certain models: Lagergreen (pseudo first order model), Ho (pseudo second order model), Elovich (heterogeneous biosorbent model), Webber–Morris (intraparticle diffusion model) and McKay (film diffusion model). The corresponding kinetic model suggests that this biosorption process followed a pseudo-second order kinetic model and was developed in two controlled steps beginning with film diffusion and followed by intraparticles diffusion.
