Activating Paper Applying Gelatin, Starch and Chitosan Coatings Loaded With O/W Emulsions Encapsulating Rutin, Carvacrol and α‐Tocopherol

Packaging Technology and Science, EarlyView.
Emulsion type governed the microstructure and functionality of papers coated with biopolymers matrix loaded with hydrophobic bioactives encapsulated into O/W emulsions. Emulsified systems improved UV–Vis barrier and antioxidant activity, whereas gelatin coatings with conventional or Pickering emulsions provided the greatest mechanical reinforcement ...

Relationship Between Micro‐Level Circular Economy and Sustainable Performance in the Metalworking Industry

Sustainable Development, EarlyView.
ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...
