REDUCING THE AIR POLLUTION IMPACT OF THE RECYCLED AUTO VEHICLES
Abstract
This paper addresses the problem of atmospheric pollution due to the scrapping of motor vehicles. Most of the materials used in the automotive industry are non-renewable, so the decommissioning of cars is a global problem. The environmental impact of this type of pollution is irreversible. In Romania, this problem is amplified by the purchase of second-hand cars that have a low life expectancy and are much earlier in the situation of being scrapped. Recovery of scrapped materials must be done selectively because a number of such products are top polluters (lead, engine oil, antifreeze, old air conditioning freon). If the recycling rate was around 70% between 1980 and 1990, starting in 2015, the reuse and recycling percentage increased to about 85%. Government programs support dismantling of vehicles, but the issue of component recycling does not provide a vision for the circular economy of these materials. Transforming the need for scrapping cars to save money, metal can be reused (about 75%), tires can be recovered (about 3%), batteries can be reused (about 1%) or can be reused and recovered (about 3%).
