Automobile industry waste production

The minerals processing industry has made contributions to all areas of technology, both in terms of products and processing. Technologies developed in the mineral industry are used extensively in the chemicals industry as well as in municipal and industrial waste treatment and recycling industry, eg, scrap recycling, processing of domestic refuse, automobiles, electronic scrap, battery scrap, and decontamination of soils. 

CBPC matrix composites can incorporate a high volume of industrial waste streams such as fly ash, mineral waste such as iron taUings and Bayer process residue from the aluminum industry (red mud), machining swarfs from the automobile industry, and forest product waste such as saw dust and wood chips. Table 14.1 lists some of these waste streams and potential products or applications. 

Subsurface soils and groundwaters can become contaminated with heavy metal as a result of a number of activities, including the application of industrial waste, fertilizers, and pesticides mining, smelting, and metal plating/metal finishing operations automobile battery production vehicle emissions and fly-ash from combustionAncineration processes. 

The use of ultrafiltration (UF) membranes for the separation of dissolved molecules of different size and nature has seen an increased interest in recent years. Depending on their pore size, membranes can be used in a variety of fields, such as removal of particulates from air, filtration of colloidal suspensions, treatment of product streams in the food and beverage industry, recovery of useful material from coating or dyeing baths in the automobile and textile industries and treatment of industrial waste waters (J, 2 ). UF membranes also serve as supports for ultrathin reverse osmosis (composite) membranes. 

Today, plastic used in the automobile industry is receiving some attention from academics however, the majority of the focus on waste plastics is by the automobile company along with the utilisation of waste plastic in its products. The automobile industry has improved production using process development one step involved the utilisation of plastics waste to create economic models for the automobile market. Economy can be realised by implementing the recycling of waste as opposed to its disposal. 

Active carbons are unique and versatile adsorbents, and they are used extensively for the removal of undesirable odor, color, taste, and other organic and inorganic impurities from domestic and industrial waste water, solvent recovery, air purification in inhabited places, restaurants, food processing, and chemical industries in the removal of color from various syrups and pharmaceutical products in air pollution control from industrial and automobile exhausts in the purification of many chemical, pharmaceutical, and food products and in a variety of gas-phase applications. They are being increasingly used in the field of hydrometaUurgy for the recovery of gold, silver, and other metals, and as catalysts and catalyst supports. They are also well known for their applications in medicine for the removal of toxins and bacterial infections in certain ailments. Nearly 80% (-300,000 tons/yr) of the total active carbon is consumed for liquid-phase applications, and the gas-phase applications consume about 20% of the total production. 

In some cases, the advantage of a sustainable product is specific and readily observable by the customer, such as a Post-it Recycled Paper Notes, made with 100 percent recycled paper fiber (20 percent post-consumer waste). 3M paint replacement films, which allow automobile and aircraft manufacturers to reduce their use of paints and solvents, are an example of an industrial application where the customer is striving to achieve its own sustainability goals. 

Ammonia can also enter the atmosphere by volatilization from the waste water of industrial processes that involve its production or use, and from the volatilization from the effluent of waste water treatment plants (Buijsman et al. 1987 Langland 1992 Roy and Poricha 1982 Wilkin and Flemal 1980). Ammonia has been found in the exhaust of automobile and diesel engines (Asman et al. 1998 Pierson and Brachaczek...
