Blockchain para fomento da economia circular na construção: um panorama sobre a produção científica

Abstract

O impacto ambiental promovido pela indústria da construção atrelado a carência de tecnologias para gestão de resíduos, evidencia o potencial da tecnologia de registro blockchain para apoiar iniciativas circulares no setor. Este artigo apresenta um panorama da literatura atual sobre o uso da blockchain para a gestão de resíduos e fomento da economia circular na construção civil. A pesquisa bibliográfica utilizou indicadores bibliométricos e cientométricos e realizou uma análise de conteúdo para identificar tendência e lacunas do conhecimento. Como resultado, observam-se avanços ainda incipientes e possível tendência futura a estudos integrando outras tecnologias para suporte, como internet das coisas e inteligência artificial.

Blockchain-based framework for improving waste management and circular economy in construction

“…Such evidence was used in the decision making about the structure of the platform to be developed in Stage 3. These results were published by the current author on Barreto Neto et al [13] and Costa et al [9].…”

“…At this stage, the need for transportation tracking was considered. Costa et al [9] highlights the potential for registration and monitoring of materials from intelligent transportation using BT. Kouhizadeh, Zhu and Sarkis [3] indicates that BT contributes directly to the process of global trade digitization by enabling multiple trading partners to collaborate using shared visualizations and updates of data details regarding waste transportation.…”

“…It has strong potential to drive circular economic initiatives, since BT acts as a facilitator that can moderate relationships with diverse stakeholders, can bring more transparency to processes involving waste management, and can minimizing the need for intermediation IOP Publishing doi:10.1088/1755-1315/1101/6/062009 3 in transactions [8]. Costa et al [9], in turn, indicate that the use of BT can be applied to life cycle analysis, construction management, materials value management, inventory management, and stakeholder performance, among other practices linked to the circular economy. Studies on BT highlight that it is a recent concept, whose unique characteristics have inspired wider use in distinct markets [10].…”

“…The technology provides decentralization, security, immutability, auditability, reliability, transparency, disintermediation, and veracity in data processing [6]. Thus, the association of BT to CE has been adopted by the productive sector seeking greater automation of processes and reliability of information [9].…”

“…Even though it is an emerging technology that can support the CE paradigm. In the academic field, it is observed that most of the existing studies have an exploratory nature, which tends to address optimization, servitization, recycling, energy efficiency, and modularization [9]. In the market sphere, it is observed that only two of the thirteen Brazilian constructechs working with CDW mapped in Table 1 use BT as main technology.…”
