The present disclosure teaches magnesium scrap cleaning processes that remove surface oil, grease, hydrocarbons, and other contaminants from dirty, magnesium scrap produced from different machining operations and provide clean magnesium scrap ready for re-melting. The magnesium scrap cleaning processes can reduce the dross produced during re-melting of the magnesium scrap.

A method for recovering noble metal from a heterogeneous catalyst comprising a solid carrier material and palladium, platinum or rhodium, present at least partially in elemental form, said method comprising the steps of converting the noble metal to an oxidation state>0 by treating the heterogeneous catalyst with an oxidizing agent in the presence of hydrochloric acid so as to form a two-phase system A comprising a hydrochloric aqueous phase A1 and a solid phase comprising the carrier material which is insoluble therein, optionally, at least partially separating the hydrochloric aqueous phase A1 from the two-phase system A and adding a further aqueous phase to the remaining residue of the two-phase system A so as to form a two-phase system B comprising a hydrochloric aqueous phase and a solid phase comprising the carrier material insoluble therein.

Disclosed is a system and method for the recycling of waste composite feed materials such as printed circuit boards (PCBs), batteries, catalysts, plastic, plastic composites such as food packaging materials, for example Tetra Pak, mattresses, compact disks (CDs, DVDs), automobile shredder residue (ASR), electric cable wastes, liquid display panels, mobile phones of various sizes or combinations of the above using a new pyrolysis system and method.

Systems and processes for recycling printed circuit boards, wherein precious metals may be reclaimed. The system generally includes a number of modules to systematically remove materials from the printed circuit boards and to separate the precious metals from the materials.

A method for recycling used cells such as saline cells, alkaline cells, button cells and used rechargeable batteries, includes the step of introducing the cells and/or rechargeable batteries as feedstock into a metal melting furnace, at the charging door thereof. The cells and/or rechargeable batteries are subjected to a compression operation in order to remove the electrolytes contained in the cells and/or rechargeable batteries, prior to introducing the cells and/or rechargeable batteries into the metal melting furnace.

The method can be used for recycling used cells and rechargeable batteries.

An apparatus for carrying out size reduction of battery materials under immersion conditions can include a housing configured to hold an immersion liquid comprising at least one of sodium hydroxide and calcium hydroxide. A first feed chute may define an opening therein for receiving battery materials of a first type into the housing and a first submergible comminuting device may be disposed within the housing and submerged in the immersion liquid to receive the battery materials of the first type from the first feed chute. The first submergible comminuting device may be configured to cause a size reduction of the battery materials of the first type to form a first reduced-size battery material.
