The effect of sewage sludge application to an agricultural soil on the fecundity of the Rose Grain aphid (Metopolophium dirhodum).

open access: yes
A pot trial was used to assess the effect of amending soil with sewage sludge on the number of offspring produced by individual Rose Grain Aphids. Results demonstrated that the highest application rate (100 t.d.s.

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2842-2861, June 2026.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

A Comprehensive Review of the Key Factors Affecting Biogas Production From Anaerobic Digestion of Organic Waste

open access: yesCleanMat, Volume 3, Issue 2, Page 74-98, June 2026.
Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

The Challenges of Domestic Wastewater/Sewage Systems for Māori Communities

open access: yesKōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
The development of domestic wastewater systems in contemporary Aotearoa New Zealand has presented a significant challenge for Māori communities. While those communities have supported attempts to address the pollution of land and waterways through modern treatment methods, the solution has included continuing discharges of sometimes untreated and often
