Recovery of aluminum from plastic packages containing aluminum by gasification.

The standing pouch, a packaging material made of multiple layers of plastic and metal, presents a significant challenge for full recycling. Gasification shows promise as a method to recover aluminum from this type of waste and convert it into energy. This study aims to evaluate the efficiency of gasification in treating aluminum-containing plastic packages, and recovering aluminum while identifying the optimal combinations of temperature and equivalence ratio (ER) to achieve the best outcomes.

Reutilization of Fe-containing tailings ore enriched by iron(iii) chloride as a heterogeneous Fenton catalyst for decolorization of organic dyes.

In this study, the Fe-containing tailings (Fe-TO) ore was reutilized and enriched with FeCl as a heterogeneous catalyst for the Fenton process to degrade the organic dyes from aqueous solution. The determinants of the heterogeneous catalytic Fenton system which included iron modification ratio, solution pH, catalyst dosage, HO dosage and initial concentration of organic dyes were systematically investigated. The modification ratio of 15% (w/w of iron), pH of 3, MFe-TO15 dosage of 0.
