Towards Sustainable Composting of Source-Separated Biodegradable Municipal Solid Waste—Insights from Long An Province, Vietnam

Sustainability, Journal Year: 2023, Volume and Issue: 15(17), P. 13243 - 13243

Published: Sept. 4, 2023

Inadequate municipal solid waste (MSW) management has become a pressing concern, resulting in significant environmental contamination, particularly developing countries. Composting demonstrated its practicality and feasibility for addressing this issue; however, the lack of at-source separation remains major challenge. As result, study, first sustainable MSW at source was conducted Tan An City, Long Province. The objective study to evaluate compost process quality using City’s separated biodegradable organic as raw material, through windrow composting with active aeration. Biodegradable waste, slow-biodegradable plastic accounted 84.5%, 15.1% 0.4%, respectively, total waste. pH, moisture, volatile percentage, nitrogen, carbon carbon-to-nitrogen ratio were 8.7 ± 0.4, 76.8 1.9%, 68.3 1.3%, 2.1 0.1%, 35.7 2.2% 17 0.8, respectively. Rice straw mixed bulking material 31%:69% achieve moisture content 55% mixture. After 10 weeks, an evaluation compost’s revealed potential suitability agricultural applications. Notably, Salmonella not detected compost, heavy metal levels below standard limits, indicating safety compost. To ensure optimal nutrient effective plant growth, slight nitrogen phosphorus supplement recommended. Aligned C/N 12.1 consistent temperature approximately 29 °C, indicates high degree maturity stability process. framework demonstrates effectiveness paving path management.

Enhancing soil microbiome resilience: the mitigating role of silicon against environmental stresses

Frontiers in Agronomy, Journal Year: 2024, Volume and Issue: 6

Published: Oct. 4, 2024

The soil microbiome plays a pivotal role in the functioning and resilience of agricultural ecosystems, contributing to critical processes such as organic matter decomposition, nutrient cycling, plant growth promotion. However, is constantly challenged by various environmental stresses, including drought, heavy metal contamination, salinity, climate change, which can significantly disrupt delicate balance ecosystem. In this context, application silicon (Si) has emerged promising strategy mitigate adverse effects these stresses on microbiome. This review paper synthesizes current understanding impacts explores potential Si mitigating agent enhancing microbial community. Silicon enhance through several mechanisms, increasing pH, improving water availability uptake, altering root exudation patterns physiology, directly stimulating abundance, diversity, functional key groups. By microbiome, help maintain ecosystem services provided microorganisms, ultimately sustainability productivity systems. also highlights future research aspects, elucidating precise mechanisms Si-microbiome interactions, evaluating long-term resilience, optimizing strategies for specific crop-soil systems, integrating management with other sustainable practices, assessing microbiome-mediated services.

The New Zealand Biodiversity Factor—Residential (NZBF-R): A Tool to Rapidly Score the Relative Biodiversity Value of Urban Residential Developments

Land, Journal Year: 2025, Volume and Issue: 14(3), P. 526 - 526

Published: March 3, 2025

The loss of biodiversity in urban residential areas that are densifying response to increasing housing demand has serious implications for ecosystem functioning and human wellbeing. There is an urgent need integrating biodiversity-sensitive design into planning development. While several existing “Green Factor” tools guide greening strategies cities, none have as their primary focus. We describe here a tool specifically evaluates developments, with particular emphasis on supporting native biodiversity. NZBF-R (New Zealand Biodiversity Factor—Residential) also educates users through embedded explanations how various features positively impact it provides tailored recommendations effective enhancement, enabling professionals make informed landscape decisions. Developed literature review, analyses Green Factor tools, robust weighting process, the identifies ranks characteristics support biodiversity, based evidence from scientific literature. demonstrate application one case study. can be applied across planning, design, retrofitting stages projects, making valuable resource planners designers.

Published: March 31, 2025

Background A 4-year field study, on the adoption of a Biologically-Enhanced Agricultural Management (BEAM) protocol, in cotton/cover-crop rotation Turkey, was designed to observe “change-over-time” soil organic carbon (SOC%) and total nitrogen (TSN%) at three profile depths (0–15 cm, 15–30 cm 30–45 cm) while tracking farm productivity profitability. Methods BEAM systems employ regenerative practices: (a) no-till, (b) no, or reduced synthetic nutrient amendments, (c) continuous roots ground (commodity/cover), accompanied with an injection (in-furrow planting) extract beneficial microbes, from Johnson-Su bioreactor.
