ABSTRACT
In today’s competitive construction industry, ready-mixed concrete (RMC) batching plants should produce and operate in a green manner when the related legal regulations on the protection of natural environment and urban life are taken into account. At the end of each working day, both residual and over-ordered fresh concrete in truck-mixers returns to RMC batching plants. For these wastes, there are fresh concrete recycling plants which make aggregate and water reusable and decompose sand and cement from the fresh concrete. In some countries, such plants are not popular because of financial and economic reasons, and thus, it becomes inevitable that the concrete waste pollutes the external environment. Therefore, in the current study, the establishment of such a recycling plant for fresh concrete wastes was investigated from a cost management perspective. In doing this research effort, components of the life cycle cost analysis were mainly examined. In fact, these are composed of all fixed and variable costs related with the investment throughout the recycling plant’s whole life. These costs can be listed as follows: (i) capital costs, (ii) operating costs, (iii) maintenance costs, and (iv) replacement or retirement costs. Consequently, the recycling concept in RMC batching plants was discussed in a detailed manner from a cost-focused viewpoint.
