Laguna Castellanos et al. 61 Figure 1. Flow diagram of treatment and separation plant for municipal solid wastes. The first step of separation of plastic wastes from the overall waste stream was successfully achieved in an industrial plant having a capacity of 7x104 tons year which was designed by ENADIMSA Spain and operated in Madrid according to the layout given in Figure 1. The economic evaluation once the recyclability 62 Management of Plastic Wastes was determined was made taking into account the actual sale price of the wastes based on the amortization costs and profitability of the plant during the 1983-86 period. A preliminary economic study was conducted using a classic method based on Engines and Machinery. The results obtained were then taken as starting data for more realistic evaluation based on the state of the Spanish polymers market in the 1985-1988 period. Only the main results of these works will be presented here with the goal of showing that the plastics recycling business is also very attractive from an economical point of view. EXPERIMENTAL Materials The film plastic wastes were supplied by ENADIMSA from the Municipal Treatment Plant of Urban Solid Wastes in Valdemingómez Madrid . The identification of polymers present in plastic wastes was carried out by IR and DSC methods. The results are compiled in Table 1.

The physical properties of virgin polymers supplied by Repsol Química . wastes and of polymers chosen as interfacial modifiers are collected in Table 2. Procedures and Utilities The study of the rheological behavior of wastes and HDPE LDPE system was carried out using a O. .
