Resumo: | Although some countries have presented positive results from strategies to reduce construction and demolition (CDW) waste generation and/or increase recycling, many have high generation rates and low recycling rates, like Brazil. This paper presents results of two case studies, involving CDW recycling plants: a) with external sale of recycled aggregate (RA); and b) without external sale of RA, with the objective to analyze financial results, the main influence factors and the role of different players in the viability of CDW recycling. Results show the essential role that must be played by the Public Power in terms of waste flow guarantee: the arrival of the waste in the recycling plants and the consumer market for the recycled product. However, while landfill disposal and natural aggregate are available at a relatively low cost,the flow guarantee is a challenge. Both cases showed a positive financial result, considering the first years of operation. In the first, results showed advantages in the 75t/h plant compared to the 50t/h plant. In the second, the amount of the recycled aggregate consumed is a key factor in order to optimize the costs related to the implementation and operation of the construction waste recycle plant. |

Esse artigo apresenta dois estudos de casos que envolvem implantação e operação de plantas de reciclagem: a) com venda externa de agregado reciclado (RA); e b) sem venda externa de reciclado. O objetivo do trabalho consisitu em analisar resultados financeiros e tempo e retorno de investimentos em diferentes cenários, assim como fatores de influência e papéis dos agentes. Os resultados mostram o papel essencial do poder público na garantia do fluxo de chegada do resíduo na planta e saída como agregado. Entretanto, enquanto as taxas de cobrança de disposição dos resíduos e o preço de agegado naturais são relativamente baixas, o fluxo se torna um grande desafio. Ambos os casos mostram cenários com resultado financeiro positivo nos 10 primeiros anos de operação. No primeiro, os resultados apontam vantagens na planta de 75t/h em comparação à de 50t/t. No Segundo, a demanda de agregado reciclado é um fator-chave para a otimização dos custos relacionados à implantação e operação da planta de reciclagem de RCD.UFSC - Federal University of Santa Catarina2021-04-192023-05-29T21:27:53Z2023-05-29T21:27:53Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/421510.29183/2447-3073.MIX2021.v7.n2.79-92https://repositorio.ufsc.br/handle/123456789/246556Mix Sustentável; Vol. 7 No. 2 (2021): Mix Sustentável (edição regular); 79-92MIX Sustentável; v. 7 n. 2 (2021): Mix Sustentável (edição regular); 79-922447-30732447-0899reponame:Repositório Institucional da UFSCinstname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/4215/3577Copyright (c) 2021 Andrea Parisi Kern, Joana Michelon Moresco, Eduardo Pizoni, Marco Aurélio Stumpf Gonzálezinfo:eu-repo/semantics/openAccessKern, Andrea ParisiMoresco, Joana MichelonPizoni, EduardoGonzález, Marco Aurélio Stumpf2023-05-29T21:27:53Zoai:repositorio.ufsc.br:123456789/246556Repositório InstitucionalPUBhttp://150.162.242.35/oai/requestopendoar:23732023-05-29T21:27:53Repositório Institucional da UFSC - Universidade Federal de Santa Catarina (UFSC)false |
