E-Waste Recycling

Technological waste is currently one of the most important problems in this era of information and technology. The volume of electronic and electrical waste (e-waste) rises day by day due to a rapidly developing industry and technology, in tandem with the ever increasing need of a growing population. 

The major end-of-life devices and equipment are as follows: televisions, computers, printers, telephones, fax machines, photocopiers, screens, DVDs, VCRs, integrated circuits, semiconductors, printed circuits, sensors, cables, etc… According to the results of surveys conducted (data of 2009); 350,000-400,000 tones of e-waste emerges annually in Turkey and only 10,000 tons (2.5%) of this amount can be collected and be a subject to a healthy recyling process by the licensed recycling companies.
 
90,000 tons of the remaining e-waste are collected by the waste collectors and are disposed of in various ways, whereas the majority 300.000 tons are lost within other waste like iron and steel, thus resulting in a valuable loss of precious metals and conductives.

This kind of waste is quite hazardous to human health and the environment due to the toxins that it contains, such as chlorinated solvents, brominated flame retarders, PVCs, heavy metals, plastic and gases, lead, mercury and cadmium. For instance it is known that 4-6% of the weight of a PC screen with a CRT (cathode ray tube) consists of lead. The effects of these toxins on human health and the ability to reuse these precious metals through recycling highlights the importance of recycling e-waste and the precious metals contained within them. Thus, globally speaking and for the sake of a viable environment, it is an important process to have these wastes collected solely by professionals, seperated and finally recycled.

Technical competency, environmental awareness and, most of all, training and a sense of awareness are required in order to collect e-waste and to get them through the recycling process. Evciler has completed its investment in an almost hands-off, integrated processing facility with a capacity of 10,000 tons e-waste/year, and has succeeded in reaching the maxiumum recycling rate. The company’s innovative and dynamic structure, in addition to its team of experienced experts allows it to constantly expand its scope.

The principles concerning e-waste and the limits and regulations related to the use of hazardous materials in electrical devices are defined in the “Limiting of Some Hazardous Materials in Electrical and Electronical Devices Regulation” issued on May 30, 2008 in Turkey, and expected to take effect in 2011. As the regulation has not gone into effect, there is no current official regulation yet. However; companies with a Certificate of Conformity, issued by the Ministry of Environment and Forestry operate in the field of e-waste recycling, carrying out the processes of collecting, seperating and reuse of these waste. In addition, these certified companies must declare the details of their monthly activities to the Ministry of Environment and Forestry. As of March 2011, 16 companies are active in this field in Turkey.

Evciler, whose scope of activities is closely interrelated with environmental awareness, is getting prepared for the near future when the regulation will take effect. The company continues to manage its activities in accordance with both its quality policy and the Certificates of Corformity issued by the General Directorate of Environmental Management of the Ministry of Environment and Forestry.

The waste that can processed on the Evciler premises, in accordance with the Certificate, are listed below:

  • Large household appliances (dish washing machines, washing machines etc.)
  • Small home appliances (vacuum cleaners, toasters etc.)
  • IT and telecommunication equipment (computers, telephones etc.)
  • Consumer equipments (video cameras, musical instruments etc.)
  • Lighting equipment (flourescents, energy-saving bulbs etc.)
  • Electrical and electronical devices (drills, saws etc. except large and fixed industrial equipment)
  • Toys, entertainment and sports equipment (video games, automatic dispensers etc.)
  • Monitoring and control devices (thermostates, heat regulators etc.)
  • Automatic dispensers (ATMs, beverage vending machines etc.)

Regarding e-waste collection, Evciler thrives to reach all companies and municipalities which can be considered as e-waste producers throughout the country.

For Evciler, recycling starts with the collection of e-waste, followed by the seperation and the process is completed with reporting of the precious metals and raw metarials that are generated during recycling process. In the recycling loop, materials are first collected and transferred to facilities by suitable vehicles and licensed drivers. The waste then go through initial sorting stage before being classified into relevant types, and then processed. The generated materials are re-classified according to their types, and sent to relevant institutions to enable their diversion into raw material and their consequent return/recycling into the economy.

The stages of recycling;

  • E-waste collection: In case of long-term collections, it is possible to allocate waste boxes or containers (for large amounts), or for singular collections that will take place only once, waste can be collected from the customers premises based on a contract.
  • Transfer of e-waste: Transfers are realized by drivers holding ADR (European Agreement Concerning the International Carriage of Dangerous Goods by Road) certificates, licensed vehicles equiped with special metal and plastic containers and trained staff. If necessary, materials can be transferred in sealed containers and opened in the facilities under the supervision of an auditor. Required regulatory forms are completed and the Provincial Department of Environment, as well as the Ministry of Environment and Forestry, are informed for each waste collection and transfer.
  • Initial sorting of e-waste: The initial sorting process is realized during the unloading of the materials from vehicles; car batteries, lighting equipments containing flourescents, lamps and monitors are classified while remaining waste is taken to storage.
    • Car batteries are collected in temporary car battery storage sections, and sent to relevant car battery recycling facilities.
    • Alkaline batteries are disposed by means of transferring them to the authorized collecter, namely the Turkish Portable Battery Manufacturer and Importer Association (TAP).
    • CRT tubes, monitors and the flourescent lighting equipment generated on the Separation and Disassembly Line and during the initial sorting process are stored in a seperate division, and then transferred to Izmit Waste and Residue Treatment, Incineration and Recycling Inc.Co. (IZAYDAS) for disposal.
    • Other waste that contains precious metals, such as electronic cards, floppy disks and HDDs is sent to another storage area for transferring to licensed recycling companies located abroad.
  • E-waste storage: Waste materials are placed in suitable metal and plastic boxes, and stored in appropriate and safe conditions until processing.
  • Disposal of e-waste: Using a forklift, stored materials are tossed into a shredder where they are reduced to pieces smaller than 1 cm2. An automated system separates these pieces according to their weight and conductivity. Following further separation, they are placed into big bags, wrapped and weighed.

The entire disposal process is recorded by security cameras, and can be watched via the internet connection at any time.

  • Recycling: Recycling methods of materials acquired at the end of the process: 

    • Iron; is sold to recycling premises to be converted back into the raw material form and then used in manufacturing.
    • Noncorrosive; is sold to recycling companies.
    • Copper, brass is sold to recycling premises to be converted back into the raw material form and then used in manufacturing.
    • Plastics; are sold to recycling premises to be converted back intoraw material form and then used in manufacturing.
    • Ni-cd, NiMH and Li-on batteries; are recycled by means of export to licensed recycling companies abroad.

  • Reporting: All the stages of the recycling process are filmed and recorded; recycling, output and disposal rates can be reported.
