Abstract
This paper proposes an economic analysis of technologies in construction and demolition waste management. The processing technologies analyzed are the current advanced, the advanced and the advanced sorting. The methodology adopted is in the economic evaluation concept of projects and it is classified with a scoping study phase. In these contexts, three levels of CDW's processing capabilities for recycling platforms are analyzed (100, 300 and 600 thousand tons per year). This article considers data base obtained from similar projects, published in specialized literature and the data sources are mainly from the European continent. The data costs researched and estimated are analyzed. The model adopted for the calculations and the simulations of the results, in the economic order, was the method of discounted cash flow and the main indicators analyzed are IRR (internal rate of return) and NPV (net present value). The paper shows that current advanced process has better economic performance, in terms of IRR. The IRR associated with advanced and advanced sorting processes could be raised by higher capacity of platforms and/or by higher sharing of better quality material in the total production. The first two points depend on the market conditions (prices and total quantity of CDW available) and (potential) fiscal or incentive policies.
