Interaction of MgO Recyclate‐Based Cermet Anode With KF‐AlF3‐Al2O3 at 800°C During Laboratory Scale Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, EarlyView.
A carbon‐free, as‐sintered MgO–steel cermet anode, fabricated via cold isostatic pressing using MgO–C refractory recyclate, was evaluated under laboratory‐scale K‐cryolite electrolysis at 800°C. Operation at this reduced temperature, combined with the electrolyte's limited electrical conductivity, led to an increase in cell voltage.

An assessment of environmental impacts of cassava starch extraction technologies [PDF]

, 2011
The environmental impacts of the transformation of cassava roots into starch were assessed for three contrasting technologies at small and large scale (1-2 and 100-200t starch per day), using the Life Cycle Assessment (LCA) methodology. The objective was

Water Recycling – Industrial Applications

Water Science and Technology, 1982
The application of industrial water recycling techniques is demonstrated by examples of various industrial branches such as: steel production, pickling and plating, coal mining and coking, sulphite cellulose and paper production, sugar works, and power plants. Special consideration is given to water recycling in metal finishing works and paper mills.

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

Advanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Matching livestock manure with suitable bioconversion strategies for efficient nutrient upcycling in China

Resources, Environment and Sustainability
Manure recycling is a priority in maintaining nutrient cycles within safe and just Earth System Boundaries. However, how to upcycle manure nutrients for higher bioeconomic benefits remains unclear, largely due to insufficient attention to matching ...

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

Advanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Isotopic values of the Amazon headwaters in Peru: comparison of the wet upper Río Madre de Dios watershed with the dry Urubamba-Apurimac river system [PDF]

, 2012
RATIONALE: The Amazon River is a huge network of long tributaries, and little is known about the headwaters. Here we present a study of one wet tropical Amazon forest side, and one dry and cold Atiplano plateau, originating from the same cordillera.

Water Recycling – Research Needs

Water Science and Technology, 1982
The very wide spectrum of potential applications for re-used water is reflected in a need for research in many diverse areas. The most critical area is re-use for potable supplies, and here the identification of potential health effects is paramount. Other areas of application and their research needs are also considered.
