TL;DR: In this article, the authors identified a common Streptomyces sp. (MN262194) from forest soil as an efficient decolorizer of triphenylmethane (TPM) dyes.

TL;DR: In this paper, a research and development project focused on the integration of serial treatment processes, including the use of moving bed biofilm reactor (MBBR), pre-treatment with sand filters and activated carbon filters, and membrane technology for aerobically-digested palm oil mill effluent (POME) treatment.

TL;DR: In this paper, the potential use of digestates from anaerobic reactors treating food waste in single (D1) and two-stages (D2: hydrolytic/acidogenic and D3: acetogenic/methanogenic) configurations was evaluated.

TL;DR: In this paper, thin-film composite with embedded polyester screen, cellulose triacetate with a cast nonwoven and CTA-ES was examined as the intermediate membranes in osmotic microbial fuel cells (OsMFCs).

TL;DR: In this paper, the authors investigated the kinetic behaviors and gas evolution of Rice straw, sewage sludge, and their blends under co-thermal decomposition processes using Thermogravimetric analysis combined with Fourier-Transform Infrared Spectroscopy (FTIR).

TL;DR: In this article, a metakaolin-based geopolymer was used to tackle the problem directly in an actual industrial environment, which allowed a rapid consolidation at room temperature, the average compressive strength was between 14 and 43 MPa.

TL;DR: In this article, an industrial applicability of the eco-composites was verified through the production of five different consumer products by extrusion and injection processes, using mixtures with 40% coffee husks.

TL;DR: In this paper, a KFeS2 whisker was formed in mass production at a low temperature, with waste cold-rolling sludge as Fe source, which exhibited good performance in the removal of Zn/Ni from real electroplating effluent.
