Evidence-based study of the impacts of maintenance practices on asset sustainability

In practice, without clear evidence of the positive impacts of maintenance on sustainability, organisations/companies are not encouraged to look at (or invest in) maintenance as an effective tool to enhance sustainability. Therefore, it is essential to show them that such evidence exists, which is the aim of this paper. The paper reviews and analyses evidence from the literature about maintenance’s social, environmental, and economic impacts. It identifies the required sustainability-related indicators associated with these impacts and provides aggregate quantified percentages for them (positively or negatively), as shown in the reviewed papers. An evidence-based research is conducted in this paper to achieve this purpose. The search process results in a research sample of 58 publications that have been surveyed and analysed. Based on the conducted analysis, the results show that maintenance positively impacts economic, environmental, and social sustainability. Many reviewed cases appear in manufacturing and buildings (both residential and commercial) and primarily consider environmental and economic sustainability indicators. The cases with social sustainability indicators are limited. Regardless, these results bring adequate evidence to encourage researchers and practitioners to view maintenance as a practical approach to improve sustainability and to investigate more in this domain.
