Chapter 2: Background
The problem of tyre waste management is a significant problem for many
countries. Privately owned vehicles as well as public transportation vehicles, such as
buses and taxis, produce thousands of tons of waste tyres every year. In this chapter,
we describe basic tyre designs along with possible recycling technologies and
regulations that have an impact on tyre waste management.
2.1 Tyre Manufacturing Techniques
In this section we will give an overview of the methods used to make current
motor vehicle tyres. We will also discuss how tyre life can be lengthened through
different emerging technologies.
2.1.1 Conventional Tyre Designs
Creating a tyre requires processing rubber, steel, and fabric components
separately before combining them into a tyre (Refer to Figure 1) (Rodriguez et al,
2001). The rubber sap is mixed with carbon black, and a variety of chemicals. These
chemical components determine the composition and specialty of the tyre along with
curing temperature and time (Frederick, 2000).
