The chemical properties of alternatiye fuel from Automobile Shredder Residue (ARS)

Abstract

A technical object is wearing down and stop s to do its function what is connected with becoming a problem, in case of vehicles, especially in environmental aspect. The recycling rate of end-of-life vehicles (ELVs) has to increase to eighty-five per cent to 2014. Nowadays few methods of recycling can be mentioned. The most popular based on disassembly, second usage of recovered materials trough fragmentation and separation of raw materials and incineration of Automobile Shredder Residue (ARS) using maximum energy recovering and minimum emission causing processes. In this paper the methods of vehicle recycling was analyzed and discussed. Especially raw materials separation aspect was taken into consideration. An average sample of ARS which is a composition of materials like rubber, plastic, wood and fibers which is use as an alternative fuel for co-burning process in industry, was analyzed. Because of metals and organic compounds (PAHs - Polycyclic Aromatic Hydrocarbons, VOC's - Volatile Organic Compounds) toxic emission problem (combustion gas emission and waste emission with cinder) in ecology aspect it is very important to know chemical properties of burning fuel. The ARS very often consist potential hazardous on human health chemical compounds or compounds whose thermal treatment products are toxic. Even if concentration of potential dangerous compound is very low it can cause very serious consequences for environment and humans. The results of chemical properties investigation of alternative fuel from vehicle using AAS (Atomic Absorption Spectrophotometry) method are published in this paper. Also alternative solutions for those wastes (ARS) usage are proposed and discussed
