Rapid generation of waste printed circuit boards has become a very serious issue worldwide. Numerous techniques have been developed in the last decade to resolve the pollution from waste printed circuit boards and also recover valuable metals from the waste printed circuit boards stream on
It is estimated that up to 80 of a mobile phone can be reused. The most valuable commodities held within phones are precious metals such as gold silver and platinum which are contained within the circuit board. The mobile phone battery also contains many useful commodities and this can be recycled too though usually separately.
Early experiments in printed circuit boards show that it is possible to collect gold platinum iron and silver nanoparticles in less than one hour. The small-scale process can treat one circuit board at a time although it should be possible to run several circuits simultaneously Rodriguez suggests.
Recycling of WEEE is a specialist part of the waste and recycling industry. It is a rapidly growing sub-sector due largely to the implementation of the original WEEE Directive in the UK by the WEEE Regulations 2006 With that came the associated requirements for the recovery reuse recycling and treatment of WEEE.
Waste Electrical and Electronic Equipments (WEEE) is the fastest growing waste stream in the world. In 2014 a total amount of 41.8 metric kilotonnes of WEEE was generated globally. There are two main parts of a WEEEa) The Printed Circuit Board (PCB) and b) The Casing i.e. the polymer and/or metal portion that covers the PCB.

This circuit is designed with a basic astable-multivibrator designed with an IC 555 timer. A resistance probe is placed on a position where the alarm is turned ON once the water level increase to the set level. This circuit uses fewer components it can be simply connected on a printed circuit board. Alarm Circuit for Fire with Low Cost

Scientists at the Fraunhofer Institute for Laser Technology ILT in collaboration with project partners have succeeded in developing a novel industrial manufacturing process one that makes it possible to use low-cost FR4 circuit board substrates in power electronics for example in electric motors.
The high technical recyclability of platinum group metals means that over 95 recovery can be achieved once pgm-containing scrap reaches a state-of-the-art refining facility. Technical challenges exist but the main barriers to recycling pgms lie in ensuring the collection of scrap and in the capacity and technical capabilities of recycling chains around the world.
Electric Vehicle Charging Infrastructure . The Challenges. In recent years the problems of "range anxiety" associated with electric vehicles (EVs) have been alleviated by the introduction hybrids (HEVs) and plug in hybrids (PHEVs) and the development of higher energy density batteries capable of storing more energy in the same space.
Mobile phones generally charge with 5v regulated DC supply so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits breadboard circuits ICs microcontrollers etc. You can also build 6V DC 9V 12V 15V etc by using proper transformer

With over 300 tonnes of gold used in electronics each year end-of-life electronic equipment offers an important recycling potential for the secondary supply of gold. With gold concentrations reaching g/t for mobile phone handsets and g/t for computer circuit boards this "urban mine" is significantly richer than what is available in primary ores.
This is an etched circuit board that is soldered onto condensers resistors or LEDs. In the mass production of electrical technology circuit board assembly machines are important. These machines are somewhat inconsistently labelled. Other machines used for the manufacturing and assembly of circuit boards are wave soldering machines THT

Mobile phones are everywhere and many people cannot conduct their day-to-day business without them. 205 million people in the USA alone use a cell phone. Millions of mobile phones are thrown away every day and e-waste (electronic waste) is the world s fastest growing waste material.
Recycling one million laptops saves the energy equivalent to the electricity used by more than 3 500 US homes in a year. For every million cell phones we recycle 35 thousand pounds of copper 772 pounds of silver 75 pounds of gold and 33 pounds of palladium can be recovered. Top of Page.
