Advancing sustainable materials in a circular economy for decarbonisation

Journal of Environmental Management, Journal Year: 2024, Volume and Issue: 360, P. 121116 - 121116

Published: May 20, 2024

This research paper delves into the intricate interplay between decarbonisation and sustainability, focusing on adopting chemical looping technologies. Deep scenarios necessitate a profound transformation in various sectors to mitigate climate change, oil refineries, as pivotal players, must adapt these changes. Employing BLUES integrated assessment model, we evaluate evolution of refining sector pathways, emphasising its potential for sustainability through repurposing emissions mitigation. Additionally, delve technologies, including Solar Thermal Chemical Looping (STCL), Reverse Water Gas Shift (RWGS-CL), Reforming (CLR), Super Dry (SDR), elucidating their principles contributions carbon dioxide (CO2) conversion. These technologies offer promising routes CO2 capture present opportunities sustainable loop cycles, potentially revolutionising industries' reduction efforts. In world this illuminates path forward by integrating innovative management strategies.

The Utilization of Dissolved Organic Matter Spectral and Molecular Properties in Freshwater Eutrophication Studies: A Mini Review

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 151 - 151

Published: Jan. 8, 2025

Eutrophication is a major environmental issue affecting freshwater ecosystems worldwide. While its impact on the composition of dissolved organic matter (DOM) well recognized, relationships between DOM’s optical and molecular properties across eutrophication gradients remain underexplored. This review synthesizes recent research (derived from UV-Vis absorption fluorescence spectroscopy) characteristics (analyzed using Fourier-transform ion cyclotron resonance mass spectrometry, FT-ICR MS) in systems varying trophic states. Generalized additive model (GAM) analysis was used to assess correlations state index (TSI). The carbon (DOC), a254, SUVA254, SR, HIX, BIX, FI averaged 11.44 ± 11.97 mg/L, 23.23 16.95 m−1. 2.98 0.99 L·mg−1·m−1, 1.42 0.38, 2.38 1.31, 1.08 0.16, 2.11 0.44, respectively, mesotrophic middle-eutrophic sites. GAM results revealed significant linear correlation DOC properties, including FI, with TSI, suggesting that DOM accumulation intensifies eutrophication. such as O/C H/C ratios, double bond equivalents (DBEs), CHOS% content, exhibited nonlinear TSI. These trends imply shift sources terrestrial macrophyte-derived inputs those dominated by algal- sediment-derived progresses. We concluded indices alone may not serve reliable indicator states; future studies should focus integrating both offer more comprehensive assessment Given limited number variables examined this study, work only offers preliminary investigation into relationship changes More systematic focusing molecular-level analyses states broader geographic scale are needed.

A Multilevel Risk Assessment Framework for Nanoplastics in Aquatic Ecosystems

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 180 - 180

Published: Jan. 10, 2025

To date, the assessment of risks related to nanoplastics (NPLs) has been incipient. Attempts establish safety levels support decisions regarding restrictions on use or reuse materials derived from petrochemicals are critical, but complexity datasets makes it difficult communicate potential NPLs-related environmental risks. Therefore, seems essential reduce relevant data a factor/number that easier clarify whether there is risk and, above all, easily report information legislators so prohibition, reductions, and/or readjustments monitoring programs can be implemented accordingly. Accordingly, this study aimed propose an improved and tiered for NPLs following NORMAN network, which may outlined as follows: (i) conducting screenings assess level through deterministic methodologies (involving collection effective concentrations or, in their absence, no-effect lowest-effect concentrations, also known NOEC LOEC, respectively); (ii) comparing exceedance values obtained previously relation predicted non-environmental (PNECs); (iii) ranking different NPL types based prioritization indeces facilitate future decision-making. Of total six polymers available, was only possible deliver indices three (two freshwater one saltwater) due lack PNEC (PECs). The majority research topic focused PS. PS classified high-priority polymer, since its estimated index ≥65 (the base value 1). Furthermore, freshwater, PE indicated priority polymer (with exceeding 1000). It should noted other widely used (such PMMA PVC), insufficient data. therefore clear current management control measures products containing must reconsidered NPLs’ impacts.

Dissolved organic matter (DOM) exerts a crucial role in biogeochemical processes and ascertaining water quality reservoirs, where it is vulnerable to the dynamic impacts of surface inflows. However, understanding how DOM quantity biochemical features responds hydrodynamic forces tropical reservoirs remains limited. To enhance our vertical profiles characteristics under varying (strong, moderate, weak regions) Chitian Reservoir (18°43′–18°42′ N, 109°68′–109°70′ E), December 2023, we investigated concentrations column samples using multispectral techniques, parallel factor model, two-dimensional correlation analysis. Our results indicated that (4.34 ± 0.36 mg/L) are highest reservoir center, whereas total nitrogen (0.52 0.04 mg/L), phosphorus (0.02 0.03 nitrate (1.01 0.07 present their values inlet region.
