Approval requirements, Standards & Pollution control of Tyre Industry

Tyre manufacturing industry is one of the largest industries in Sri Lanka. The tyre manufacturing process begins in the rubber tree plantations. According to the data in 2002 total no. of tyres imported and manufactured in Sri Lanka is 2.1million per year. (Source: Technical Guidelines on used tyre management in SL).
This industry needs several requirements and standards are needed for its establishment and pollution control. Normally use the general standards that given by the Central Environmental Authority (CEA) for any industry. Therefore National standards and requirements for tyre industries should be prepared.
When consider the requirements that needed for a Tyre industry are, Environmental Impact Assessment (EIA) and Environmental Protection License (EPL). The EIA Should be carried out, if the proposed industry will make production of 50 tons per day. EPL for this industry should not be considered as an approval for carrying out this activity/process at this location. It is only a permit for the discharge of effluents/emissions or emitting of noise levels according to stipulated standards. There are several conditions in EPL. As an example, there are standard levels for noise that generated form the manufacturing process. Those standards vary with the time of the day.
When consider the Tyre manufacturing process, it is a complex process. Basically there are five stages. They are Mixing process, Extruding process, Plies making process, Bead making process and Building process. Wastes are generating in an every stage. The Mixing process has the highest waste generation. It is dust. Mainly the Carbon dust generated in that process. Therefore industries use dust collectors to minimize the dust emission to the environment. Because this dust affects not only to the laborers, but also to the people in the surrounding area. Another waste is rubber scraps that release in various stages. Mostly the industries sell these scraps to the rubber products manufacturers. Eg: CEAT Tyre Company sells their scraps to the DSI, Arpico, etc. noise is a pollution that happens in these industries. The industries always try to maintain the noise within the given levels in EPL. Planting trees around the periphery of the site will reduce the effect of the noises.
Therefore good practices can reduce the waste generation in the tyre industry.
