Needless to say, waste can be paid by the place where it is brought, and the money may be paid as a valuable thing oppositely. Recently, it was traded as a valuable thing, and the case where money came out came out to have paid the money so far according to the kind of the waste. For instance, the waste tire is so. As for thermal recycling, the processing cost of 40 to 60 yen per bottle was required when bringing in cement high school (for cement firing). When it is brought to the steel mill, it is bought as a valuable thing.
In this background, the demonstration operation of the new recycling process to put the waste tire into the converter by introducing the new Japan manufactured by Hirohata Ironworks from February 1999 to the steelmaking fuel, and the demand of the waste tire has increased in the full-scale operation transition. By the way, the steel plant is fitted with a cut tire input equipment to the molten iron manufacturing equipment, as a reducing agent such as carbon black included in the waste tire, the iron-funnel is used for molten metal raw material, synthetic rubber is gasifier and blowing gas. This will accelerate the thermal recycling of waste tires at once.
However, waste thermal recycling is the final means of recycling. When we consider the finite properties of resources, we want to emphasize material recycling and reuse. Generally, the recycling of waste tires is 36% material, and thermal 51%. In addition to recycled rubber and rehabilitation tires, materials such as pavement materials and mats. The remainder is exported to Southeast Asia as used tire and is used. In order for material recycling to spread, it is assumed that the price, quality, and appearance are the same or superior to the conventional products, in terms of the market for recycled products. On the other hand, standardization of JIS is also important. Otherwise, it is inevitable that the waste tire will be swallowed by the wave of the incineration principle.
