Waste Batteries Disposal and Recycling
Disposal and Recycling of Waste Batteries
IMPORTANCE OF RECYCLING WASTE BATTERIES
Since waste batteries do not show biological degradation, they cannot be disposed of by composting methods. Likewise, waste cells are not preferred for incineration because they do not burn well due to their structure and as a result they do not show sufficient shrinkage in their mass.
Controlled storage of waste batteries under or above ground is still practiced in many countries. However, after the waste batteries are classified according to their chemical structure, it is best to dispose of them by recycling processes.
The fact that EU countries' metal and metal sprouts needs are dependent on imports in the order of 80 -100% (eg nickel 86%, cobalt 95%) and the fact that batteries constitute the richest resources following primary metal shoots and alloys in terms of metal contents have been realized in a short time and In the latest Directive 2006/66 / EC published on 26 September 2006, the obligation to recycle waste batteries was clearly emphasized. On the other hand, it is also important that the amount of energy consumed in the process of obtaining metals from metal shoots is much higher than that required for the recycling of waste batteries.
RECYCLING TECHNIQUES
The objectives of recycling portable waste batteries are to protect the receiving environment from harmful emissions from waste batteries, to prevent heavy metals from entering the soil or water, and in particular to generate economic benefits by recycling certain precious metals within the batteries.
From the recycling of portable waste batteries, zinc and zinc compounds, manganese compounds, ferromanganese, ferronickel, nickel, cadmium and cadmium compounds, lithium, silver, cobalt and few rare earth elements are recycled in several large capacity plants. The recycling of mercury and mercury compounds has lost its importance as a result of the extremely reduced amount of mercury present in zinc-carbon and alkaline batteries.
Recycling methods can be mechanical, hydrometallurgical (chemical / physical) or pyrometallurgical (thermal). In the hydrometallurgical processes, it is possible to achieve a much higher degree of purity than in thermal processes. On the other hand, recycling efficiency in thermal processes is much higher.
MECHANICAL AND CHEMICAL SEPARATION
SITUATION IN TURKEY
A project titled esi Disposal of Waste Batteries and Development of Recycling Technologies ”was initiated in 2009 by TÜBİTAK Chemistry Institute. In this project, the Ministry of Environment and Urbanization is the customer institution and TUBITAK MRC is the executive organization. The aim of the project is to recycle waste zinc-carbon / alkali-manganese type batteries by various physical and hydro-metallurgical processes. EXITCOM Recycling Company was established in Kocaeli in the second half of 2017.
