Carbon Energy, EarlyView.Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Understanding the biochar's role in ameliorating soil acidity
Journal of Integrative Agriculture, 2019 Extensive acidic soils, which suffer from accelerated soil acidification, are found in southern China. Soil acidity, aluminum toxicity, and nutrient deficiencies severely limited crop productivity in acidic soils.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Isotopic exchangeability reveals that soil phosphate is mobilised by carboxylate anions, whereas acidification had the reverse effect [PDF]
SOILMineral P is an increasingly scarce resource, and therefore the mobilisation of legacy soil P must be optimised to maintain soil fertility. We have used isotopic exchangeability to probe the lability of native soil P in four contrasting soils following ...

ENERGY EFFICIENCY AND LIFE CYCLE ANALYSIS OF ORGANIC AND CONVENTIONAL OLIVE GROVES IN THE MESSARA VALLEY, CRETE, GREECE. [PDF]
, 2003 Environmental Impacts of agricultural activities have to be assessed in order to address cultural practices and the type of farming that are best suited to avoid the trade-off between the Ecology and the Economy. Furthermore, this study, comparing the

Reducing Ammonia Losses By Adding FeCI3 During Composting Of Sewage Sludge [PDF]
, 1999 The release of ammonia nitrogen during composting of sewage sludge mixed with a lignocellulosic bulking agent leads to a reduction in the agronomic value of the final compost and to harmful effects on the environment. We propose adding a cheap salt FeCl3

Influence of Different Washing Hair Procedures in the Quantitative Determination of THC and THCCOOH
Drug Testing and Analysis, EarlyView.Different hair decontamination protocols significantly affect THC quantification, with marked analyte loss—particularly after aqueous‐organic washing—whereas THCCOOH remains stable. These findings highlight the risk of misinterpretation and the need for standardized washing procedures in hair analysis.

Strategies for Controlling Acidity of Arable Soils—Sustainable Liming Systems
AgronomyStabilizing soil pH is not only a production effect, but mainly an environmental effect that requires a holistic approach and action. Current liming practices in arable soils are limited solely to mitigating and potentially eliminating the negative ...
