Implementing materials passports in the construction industry: empirical evidence from Ghana

Abstract

Purpose

The increasing concern for waste reduction in the global construction industry has led to diverse sustainable approaches emerging globally in the past decade. Material passport (MP), a growing approach, has been seen to be very promising. This study examines the implementation of materials passports in the Ghanaian construction industry.

Design/methodology/approach

The study adopted the quantitative research method. Having reviewed literature related to this study, questionnaires served as a means of soliciting the views of 77 professionals in the built environment in the Ghanaian construction industry on the theme under investigation. Descriptive and inferential statistical analyses were used to analyze the data retrieved.

Findings

Findings from the study revealed that Ghanaian construction professionals possessed a low level of awareness of the concept of MPs. However, they showed a massive willingness to adopt MPs in their professional practice. The findings further revealed that the professionals believed challenges such as the lack of knowledge, complexities of MP in terms of its preparation, and lack of quality assurance for recovered products hinder the adoption of MPs. The findings also revealed that strategies such as adequate training and education, policies and regulations, and adequate stakeholder engagement could aid in the implementation of MPs in the Ghanaian construction industry.

Originality/value

For the concept of MPs to gain a firm foundation globally, its perception and implementation must be explored thoroughly. This empirical study, being the first to investigate MP implementation in Ghana, has provided insights into the topic from the perspective of professionals operating in the Ghanaian construction industry. The paper reveals information on the practice of MPs from the context of a typical developing country.
