Climate effects of recycled fertilizers and biochar: emissions of nitrous oxide, methane and ammonia in a field experiment [PDF]

open access: yes, 2018
Background Nitrogen (N) fertilizers are essential for crop production. Farmyard manure and slurry traditionally constitute about half of the total N inputs into crop production in Switzerland.

Dynamics of Circular Economy Transformation Processes in Relation to Individual Waste Types Recycling – Net Zero for Sustainable Development

open access: yesBritish Journal of Management, EarlyView.
Abstract The main goal of the study is the quantification of the disparities in the recycling rates of the individual types of waste in the European Union member countries. The data on the waste recycling rates for the period 2004–2021 come from Eurostat. A linear regression analysis is engaged for the analytical processing.

Tracer Test as a Tool for Optimizing the Flow Patterns and Efficiency of a Full‐Scale Drainage Water Treatment Wetland

open access: yesWater and Environment Journal, EarlyView.
Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

Hierarchical Porosity Engineering of Birch‐Derived Carbons via KOH Activation for High‐Performance Aluminum Batteries

open access: yesBatteries &Supercaps, Volume 9, Issue 2, February 2026.
Birch‐wood biochar activated with KOH at ratios 1:4 (CBW14) and 1:6 (CBW16) yields hierarchical micro‐ and mesoporous carbons for aluminum‐battery cathodes. CBW14 degrades with cycling, whereas CBW16 preserves structure and capacity, showing that tuned hierarchical porosity is key to stable aluminum‐battery performance. Aluminum batteries (ABs) present

The Assessment of Anaerobic Digestion Performance and Efficiency in Terms of Waste Collection

open access: yesEnergies
Municipal solid waste (MSW) management is identified as a significant sustainability concern. Source segregation (SS) is the most effective method of managing MSW, and anaerobic digestion (AD) is the most efficient treatment method. The aim of this study

Fluorescence based detection of bioaerosols to improve emissions characterization from environmental sources [PDF]

open access: yes, 2015
Bioaerosols are ubiquitous in ambient air but there have been increasing concerns about their human exposure and to health impact due to ever increasing environmental emissions from sources such as biowaste and intensive agriculture facilities (Borlée ...
