There are very few construction and demolition (C&D) waste recycling centres in Brazil. To encourage the building and operation of new units, data were collected and analysed relating to C&D waste management and recycling in Brazil. Based on the results of this analysis, a conceptual model is presented for conducting viability studies of future C&D waste recycling centres. Applying this model to verify the viability of private recycling centres, the results show that under current market conditions in Brazil, C&D waste recycling centres are not financially feasible based solely on revenue from the sale of processed products. Nevertheless, under the same market conditions, the recycling centres could be economically viable for public authorities depending on the particular circumstances of each municipality. The feasibility, however, depends on continuity and the production volume reached. The conceptual model, the results of its applications and the discussions about the experiences of existing centres can strongly support public authorities and private initiatives in their decision-making about investments in Brazil and in other developing countries.
巴西的建筑与拆除（C&D）废物回收中心非常少。为鼓励新设施的建设与运营，收集并分析了巴西C&D废物管理与回收的相关数据。基于该分析结果，提出了一个概念模型，用于对未来的C&D废物回收中心进行可行性研究。应用此模型验证私人回收中心的可行性，结果表明，在巴西当前的市场条件下，仅靠加工产品销售的收入，C&D废物回收中心在财务上不可行。然而，在相同的市场条件下，根据每个城市的具体情况，回收中心对公共当局而言可能在经济上可行。不过，可行性取决于连续性和达到的产量。该概念模型、其应用结果以及对现有中心经验的讨论，可以有力地支持公共当局和私人倡议在巴西及其他发展中国家进行投资决策。
