E-waste Recycling

Electronic Waste Shredding

The existence of modern world is beyond imagination without the use of electrical appliances and electronic gadgets. Therefore, there is a rise in the production and consumption of electronic goods. As per estimate, globally more than 40 million tons of electrical and electronic scraps are generated every year. India is the fifth biggest generator of e-waste in the world after U.S., China, Japan and Germany. In India, about 2 million tons of electrical and electronic waste is generated every year and it is annually growing at a rate of 21 percent. Recycling of e-waste is beneficial for both economical and environmental reasons. The e-waste contains many precious metals that can be recovered during recycling process. WANROOETECH developed and designed Shredders and Granulators, especially suitable for recycling of e-waste at affordable price and easy recovery of economical products during recycling process.

The WANROOETECH E-Waste Shredders and Granulators are tailor-made to suit specific customer requirements of recycling different types of e-wastes. The metals and non-metals present in the e-wastes can be separated and recycled in an efficient and economical manner with our Electronic Waste Shredding System. We provide low-speed and high torque e-waste shredders with Single-shaft and Dual-shaft, over-band magnetic separator, metal detector and separation systems especially suitable for the recycling of e-waste. The separation and recovery are critical elements of e-waste shredding process. Our electronic waste shredder provide recycled material, which is suitable for subsequent separation of precious metals from the impurities. The WANROOETECH Shredders and Granulators can be integrated to allow efficient shredding, separation and reclamation of marketable materials from the processing and recycling of e-wastes.

APPLICATIONS:

WEEE

The Waste Electrical & Electronic Equipments (WEEE) includes all electrical appliances and electronic equipments which become waste after their useful lifespan. The scrap refrigerators, freezers, televisions, washing machines, medical equipments, IT & telecommunication equipments, etc. are included under WEEE. The WEEE generation in India is approximately 1,50,000 tonnes per year, while at global level it is more than 40 million tonnes per year. The WEEE scrap could be shredded, processed and sorted into different components to recover valuable recyclable fractions.

IT PRODUCTS

The hardware components used in various Information Technology (IT) products become scrap after the end of their useful life. The scraps of IT products include main-frame computers, personal computers, monitors, laptops, notebooks, printers, keyboards, mouse, etc. During the recycling of scrap IT products, shredders are used to generate marketable output at economically efficient manner.

SMALL HOME APPLIANCES

The small home appliances include TV sets, CD players, microwave ovens, vacuum cleaners, coffee makers, irons, toasters, hair dryers, blenders, juicers, deep fryers, etc. All these small home appliances have definite shelf life and after that they become scraps. There is a great economic potential and useful marketable fractions could be generated by shredding of scraps of various small home appliances.

REFRIGERATOR RECYCLING

Several million scrap refrigerator units are disposed every year in India and at global level. The shredding and recycling of refrigerator waste generates marketable iron, incinerable pellets, marketable plastics and marketable non-ferrous metals. The recycling of scrap refrigerators is the most significant segment after consumer electronics and has associated economic benefits.

CIRCUIT BOARD

Almost all electronic products in the world have “Printed Circuit Board (PCB)”, which is a non- conductive material with conductive lines printed on it. Electronic components are mounted on the PCB to form a working assembly. The production value of PCB is more than 30 billion dollars; however the life cycle is very short for many such products. As a result, more and more PCB based electronic waste is generated all over the world. Two types of PCB wastes need to be recycled –one from the retired electromechanical products and second from the waste of PCB  production processes. PCB recycling should separate metal and non-metal effectively and efficiently. For the reuse of metal and non-metal, the separation ratio must be very high.

WANROOETECH  offers three-stage PCB Recycling line as Primary Shredding, Granulation and Fine Grinding as a complete solution. At the stage of Primary Shredding, PCB wastes undergo size reduction to obtain more manageable pieces. This helps in easy sorting of metal from ceramics and fiber-glass. It also helps to loosen the attached pieces from the board. The rough shredded PCB materials pass through granulation and fine grinding processes, followed by a separation process where undesired materials are removed and metals are recovered. Metallurgical process is used to refine the recovered precious metal from the metal powder, while the non-metal obtained by recycling is used as filling material for building materials and so on.
