IMM contributed 40 million TL to economy from ship-waste collected

The Istanbul Metropolitan Municipality (IMM) has collected harmful wastes such as bilge, sludge, slop and oil from the ships passing through the Bosphorus, which is one of the world’s busiest waterways.

Istanbul Metropolitan Municipality's (IMM) environmental cleaning project has successfully collected 186,804 cubic meters of waste collected from sea surfaces in a year amid concerns of increasing environmental damage. As a result of the recovery of the wastes disaggregated according to their qualifications, approximately, a contribution of 40 million TL was made to the national economy. Thus, 22 million cubic meters of clean water was prevented from contamination. 

The Bosphorus is one of the busiest maritime passages in the World, with nearly 55,000 vessels passing through in 2018. Although this mobility contributes significantly to economic development, especially in the trade and tourism sectors, the hazardous waste that ships bring with them is a major threat to the seas. The Istanbul Metropolitan Municipality has been collecting the harmful wastes of the ships and preventing both sea pollution and recycling of waste according to their nature and bringing them back to the national economy. İSTAÇ has collected a total of 186,804 cubic meters of waste from 7,458 ships in the last one year.

14 Waste Collection Vessels are Operated 24/7

The IMM is the only institution that has an authority to control and manage cruise ship wastes in Istanbul's marine responsibility area and it provides services with its 14 waste reception ships and 110 personnel 24/7. Shipowners who want to hand over their waste are contacted by the IMM. The waste ship is directed to the ship's anchor point and the waste such as bilge, sludge, slop, waste oil, and sewage is delivered to the ship for a service fee. Wastes are then brought to the first waste acceptance facility (WAF) from ships was founded in Haydarpaşa, Istanbul and operated by İSTAÇ, a subsidiary of the IMM. In order to make it suitable for recycling, dewatering, treatment, de-gassing, and sedimentation are carried out at the WAF. İSTAÇ has collected 186,804 cubic meters of waste from 7,458 ships in the last one year. A total of 21,901 cubic meters of waste oil was obtained from the treated wastes.

Collected waste is recovered as raw-material 

The waste oils obtained are sent to the Ergene Recovery Plant of Enerji AŞ by licensed tankers. The obtained waste oils are transported to the Ergene Recovery Plant of Enerji Co., a subsidiary of the Istanbul Metropolitan Municipality with licensed tankers. Waste stored in giant silo tanks are heated by reactors to produce waste solvent and waste oil. These are used as raw materials in many industrial fields, especially in the petrochemical, automotive and construction sectors. Thanks to the recycling of wastes as raw materials and the reduction of imports, a contribution of 40 million TL was made to the national economy. 

1 Liter of waste oil pollutes 1 million Liter of water

Recycling of waste oils provides a significant benefit to the environment as well as the economy. According to scientific research, 1 liter of waste oil pollutes 1 million liters of clean water. The Istanbul Metropolitan Municipality (IMM) has recycled 21 thousand 901 cubic meters of waste and prevented the pollution of 22 million cubic meters of clean water at the same time in a year.
