There are a lot of ways to deal with e waste collection. While e waste recycling in Adelaide is given importance, there are other places in the world where non-environmental friendly ways of disposing waste are followed. Here we are going to share some methods of old electronics disposal.
Landfilling
One of the most popular ways of disposing off the electronic waste is landfilling. In this methodology, the soil is first excavated and then trenches are made in order to bury the e-waste into it. Following this, impervious liner of clay or of plastic is made with a leachate basin in order to collect as well as transfer the e-waste to this treatment plant. Although, this is one of the common methods followed for e-waste disposal but it is not favourable for the environment. It releases toxins like cadmium, lead as well as mercury into the soil and through leaching into the groundwater.
Acid bath
In this methodology, the electronic circuits are soaked in the solution of sulphuric, hydrochloric or nitric acid that is quite powerful. This powerful solution frees the metals from electronic pathways. The mental that is then recovered is employed in manufacturing of other products. The hazardous acid waste is discarded into the local water sources.
Incineration
This approach of disposing the electronic waste involves the combustion of electronic waste at a very high temperature in incinerators that are specifically designed for this. This mode of disposing e-waste is considered to be advantageous as it helps in getting rid of high volumes of waste while the energy so produced can also be utilized separately. However, one thing that cannot be ignored is that it releases a great amount of toxins into the atmosphere.
These are some of the commonly used methods of e-waste disposal though these are not in favour of the environment.
