Waste management and SDGs
Hazardous waste
Definition of e-waste Electronic waste, or e-waste, refers to all items
- f electrical and electronic equipment (EEE)
and its parts that have been discarded by its
- wner as waste without the intent of re-use

The properties of persistent organic pollutants and mercury
- 1. Persistence to chemical and biological
exposure
- 2. Bioaccumulation and bioconcentration
- 3. Poor solubility in water, solubility in the
fat tissues
- 4. Volatility, transboundary transfer
- 5. Toxicity: reproductive, neuro- and
immune toxicity, canceriginity
Human health effects of e-waste
lung cancer and chronic

Potential value of raw materials in waste in 2016
Стекло и керамика – 20%
Если бы каждый пользователь мобильного телефона утилизировал всего один телефон, вместе мы бы сэкономили около 240 000 тонн сырья.
black metals - 3% glass and ceramics - 20% Non-ferrous metals - 32% Plastic - 40% Others - 5%
If every one user of mobile phone utilizes
- ne phone all together we would economy
240 000 tons of raw
Nokia has conducted a research in 13 countries (Finland, Germany, Italy, Russia, Sweden, Great Britain, United Arab Emirates, USA, Nigeria, India, China, Indonesia and Brazil), in which 6,500 people took part. 3% - sent their old cell phones for utilization 4% - threw out the old devices to the landfill 15% - gave to relatives 16% - sold 44% - kept them at home 74% never thought about recycling the phone
The total weight of all mobile phones produced in the world is tens of thousands of tons per year, and tens of thousands more tons are accessories.
1 ton of gold ore
0,3- 5 g of pure gold
1 ton of cell phone
280 g of pure gold 140 g of Platinum 140 g of Copper
Only a few high-tech companies around the world can extract gold and other expensive materials from their phones, as this process is truly dangerous and can lead to poisoning.
