Process Involved in Rubber Recycling

 

The Recycling of Rubber, whether natural or synthetic, can be a tough yet lucrative process. Not only does recycled rubber cost half of newly produced natural or synthetic rubber, but has better properties than virgin rubber. Its production consumed lesser energy as well. Rubber Recycling is necessary because rubber is a major contributor towards landfill pollution. Rubber usually takes a long time to decompose and, if it is burnt, it releases carcinogenic and poisonous gases into the atmosphere. As such, not only is the recycling of rubber financially appealing, but is much needed for environmental conservation as well.

 

Process Involved in Rubber Recycling

 The Recycling of Rubber is not an easy process, yet, there are several methods that can be employed. One way of recycling rubber is to simply shred and grind it, mixing crumbs along with virgin rubber, and vulcanizing it to form new products.For rubber crumbs surface activation, different methods are developed to increase interaction between new rubber matrix and crumbs. In this way, the mechanical property of the crumbs increases.

 

3 Major Processes that are involved in Rubber Recycling:

 

Mechanical Process: In this method, the Pulverizing machine uses rotors for shredding rubber into strips, separating steel and other elements of magnet, and converting rubber into different sized granules that can be used later for various purposes.

 

Vulcanization: This process gives rubber mulch a spring like characteristic. Rubber polymers get increased strength by the addition of Sulphur and steel in it, which forms a strong bond between both of them.

 

Pyrolysis: This is a rubber melting process conducted in the absence of oxygen. This restricts combustion and toxic fumes will not be produced. During this process, rubber is decomposed into gases, char and oil.
