Doubting radiocarbon dating from in-slag charcoal
Archeologické Rozhledy, 2018 A Roman-Period bloomery smelting site had been excavated in the Lahn valley at Wetzlar-Dalheim in central Germany during 2006–2012. The production unit consisted of a big rectangular workshop pit with 13 slag pit-furnaces, two waste dumps and a small ...

Influence of Slag Composition and Temperature on Slag Foaming.
ISIJ International, 1992 The slag foaming behavior caused by the reaction between FeO containing slag and hot metal was investigated for the CaO-SiO2-Al2O3-P2O5-TiO2-MnO-MgO-CaF2 system. The peak of slag foaming height was observed when (CaO)/(SiO2) was around 1.2 and the peak value of (CaO)/(SiO2) became slightly large with the increase in temperature and the CaF2 mixing ...

Phosphorus removal in passive treatment technologies for tertiary wastewater treatment [PDF]
, 2014 The treatment of phosphorus at small sewage works requires alternative approaches to the traditional chemical precipitation and biological removal pathways, as such approaches do not align well to the requirements at such a scale in relation to the use

Business Strategy and the Environment, EarlyView.ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Slag Splashing: simulation and analysis of the slags conditions
Journal of Materials Research and Technology, 2019 The successful application of the repair and prevention of LD converters refractories technique called Slag Splashing requires a close control of the slag physicochemical properties (basicity, viscosity and surface tension), as well as suitable selection of operational parameters and geometric configurations.

Business Strategy and the Environment, EarlyView.ABSTRACT Policy intervention can be a driver for industrial symbiosis (IS). However, given the wide variety of policy instruments available, policymakers should be guided in the policy design process to ensure that their intervention is effective and efficient. In this paper, we propose an agent‐based (AB) model intended to assess the effectiveness and

Carbon Energy, EarlyView.Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and
