A method for recovering lithium from lithium ion battery scrap according to this invention comprises subjecting lithium ion battery scrap to a calcination step, a crushing step, and a sieving step sequentially carried out, wherein the method comprises, between the calcination step and the crushing step, between the crushing step and the sieving step, or after the sieving step, a lithium dissolution step of bringing the lithium ion battery scrap into contact with water and dissolving lithium contained in the lithium ion battery scrap in the water to obtain a lithium-dissolved solution; a lithium concentration step of solvent-extracting lithium ions contained in the lithium-dissolved solution and stripping them to concentrate the lithium ions to obtain a lithium concentrate; and a carbonation step of carbonating the lithium ions in the lithium concentrate to obtain lithium carbonate.

A system for decomposing a waste material in an unlined landfill including a landfill site having at least one waste disposal zone for receiving the waste material. The system also includes a remediation system configured for extracting a mixture of leachate and groundwater from groundwater within or adjacent to the landfill site and feeding the mixture into the at least one waste disposal zone along with air and other nutrients to enhance a rate of decay of the waste material within the at least one waste disposal zone.

The disclosure provides a recycle apparatus. The recycle apparatus is configured to separate a back sheet and a glass sheet assembly of a photovoltaic module. The recycle apparatus includes a conveyor, a flattening device, and a cutting tool. The conveyor includes a first roller and a second roller opposite to each other. The flattening device is located aside the first roller and the second roller. The cutting tool is located aside the flattening device. The flattening device is located between the first roller and the second roller of the conveyor and the cutting tool. The first roller and the second roller is configured to clamp the photovoltaic module and to feed the photovoltaic module to the flattening device configured to flatten the photovoltaic module and to the cutting tool configured to separate the back sheet from the glass sheet assembly.

Provided is a method for processing electronic/electrical device component waste, which can increase an amount of electronic/electrical device component waste processed in a smelting step and efficiently recover valuable metals. The method for processing electronic/electrical device component waste includes a step of processing the electronic/electrical device component waste in a smelting step, wherein prior to the smelting step, the method includes a step for reducing smelting inhibitors contained in the electronic/electrical device component waste

Compositions and methods for treating waste water produced by copper mining operations are described herein. Slag from steel making operations and other industrial waste materials that include alkali metal and/or alkaline earth elements have been found to both raise pH of the waste water and also reduce arsenic content. Following such treatment the spent slag or industrial waste can be utilized as a source of valuable metals or incorporated into stabilized building materials.
