Recycling technologies

Sharp is continuously researching new recycling technologies to support and strengthen its recycling objectives.

Memory shape - enables easy disassembly of end-of-life electronics products

The washer remains securely fastened in use (Fig. 1) but expands when heated (Fig. 2), enabling the two combined pieces to come apart easily (Fig. 3)

 

Recycling Indium from LCD waste

The technique developed by Sharp with Aqua Tech.Co.ltd takes advantage of the unique properties of this metal. LCD panels are first crushed into glass cullet (small chips) and then dissolved in an acid solution. It is a simple process using common chemicals that eliminates the need for large energy expenditures, such as those required to achieve high temperatures or high pressures.

 

Closed-loop material recycling flow for television cabinets

Sharp developed and implemented a technology for closed-loop material recycling. This enables the repeated reuse of scrap plastic components that consist of a single resin material (polypropylene [PP] or polystyrene [PS]) recovered waste appliances into new home appliances, thereby reducing the amount of virgin plastic usage and helping to save fossil resources.
