Reaction-Mediator-Based Chlorination for the Recycling of Titanium Metal Scrap Utilizing Chloride Waste

Reaction-Mediator-Based Chlorination for the Recycling of Titanium Metal Scrap Utilizing Chloride Waste

In this study, a novel chlorination technique for metallic titanium (Ti) was devised in order to establish a recycling process that uses both Ti metal scrap and iron chloride (FeClx) waste, and its feasibility was demonstrated. Direct reaction between Ti and FeClx has drawbacks such as slow kinetics of Ti chlorination and high volatilization of FeClx. To overcome these, the authors proposed a c...

Scrap prices, waste and recycling policy

This study examines the effect of waste and recycling policy on scrap prices and the importance of scrap price feedbacks as a determinate of the costs of waste and recycling policy. The effects of a deposit/refund, advance disposal fee, and recycling subsidies on scrap prices are derived, and the direct and indirect channels of waste reduction are decomposed for the three instruments. Scrap pri...

Recycling of Scrap Tires

As Rachel Louise Carson (1907-1964) successfully noted in her phrase “The human race is challenged more than ever before to demonstrate our mastery not over nature but of ourselves”, we are challenged to find ways to produce more energy, reduce our waste production while minimizing use of limited natural resources. Although recycling of materials has a history going back to the times of Plato B...

Recycling of Precious Metals from E-scrap

Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...
