Waste activated sludge high‐rate treatment of septage: Stabilization phase trials and comparison with winery wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Performance evaluation of the waste activated sludge high‐rate (WASHR) process for septic wastewater treatment. Abstract The waste‐activated sludge high‐rate (WASHR) process is evaluated as a batch‐mode pre‐treatment for actual septage using a high‐rate contact stabilization (HRCS) approach.

Clumped Isotopologue Fractionation by Microbial Cultures Performing the Anaerobic Oxidation of Methane [PDF]

, 2020
Methane is abundant in marine subsurface sediments, sourced from microbial or thermocatalytic products. The relative composition of its isotopologues (12CH4, 13CH4, 12CH3D and 13CH3D) is used to infer its sources and sinks.

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

The Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

Methane‐Driven Arsenic Biogeochemical Cycling in Deep‐Sea Cold Seeps: Implications for Oceanic Arsenic Geochemistry

Geophysical Research Letters
Arsenic accumulation in seafloor cold seeps is poorly understood. Here, we investigate the interplay between arsenic and methane biogeochemical cycles at the Haima cold seep, South China Sea.

Operational and environmental barriers to centralized composting in two small Brazilian municipalities: A longitudinal study

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Municipal solid waste management in small cities faces severe logistical and financial barriers regarding organic fraction treatment. This study evaluates biological selective collection in two small Brazilian municipalities (Astorga and Sabáudia), comparing dynamics between gated communities (GC) and public thoroughfares (PT) over an annual ...
