Exploring the contributions of circular business models towards the transition of green economy in the Ghanaian construction industry

PurposeIn recent times, both academics and industrialists have undertaken research into various areas of circular business models (CBM) in a bid to promote a green economy. Yet despite numerous studies conducted, the ensuing discourse contains scant information regarding the contributions of CBM towards the transition of green economy in the construction industry. This present study therefore aims to explore the contributions of CBM in the transition towards a green economy in the Ghanaian construction industry.Design/methodology/approachA comprehensive literature review was first conducted to identify the contributions of CBM towards the transition towards a green economy. A quantitative research strategy was then adopted to collect primary questionnaire data from professionals with knowledge of CBM and the green economy from 104 participants for the study. The data gathered was analyzed using descriptive statistics and exploratory factor analysis viz. Principal component analysis.FindingsThe contributions of CBM towards the transition towards a green economy were found to be: value contributions (i.e. lower carbon footprint, lower emission of waste by the industry, value creation for clients, innovation in construction materials and methods, reduced maintenance cost, creation of energy efficient infrastructures, improved value proposition for firms, improved sustainability of the industry and reduced pressure on finite resource.); green contributions (i.e. recycling and reuse of construction waste, promotion of green building technology, increased potential for economic growth, increased resource efficiency and creation of green building market) and longevity contribution (i.e. increased life span of buildings). It was evident that CBM make significant contributions in the transition towards green economy and as such, policymakers and other stakeholders within the construction industry must adopt these models to maximize their green credentials and accrue inherent benefits associated with transitioning towards a green economy.Originality/valueThis paper presents a novel and comprehensive study that explores the contributions of CBM towards engendering a green economy. The study’s results provide construction industry stakeholders and policymakers with clear insight into the contributions of CBM towards the transition into a green economy. In practice, this study provides much needed guidance to support construction practitioners to transition towards a green economy in alignment with the United Nations' Sustainable Development Goals (SDGs).

EFFECT OF FLY ASH ON THE PROPERTIES OF CEMENT

Effect of fly ash on the properties of cement. This experimental work is an effort to try to develop the awareness & importance trial waste management & its utilization in productive manner among the people. In today’s more environmentally-Conscious world, a more responsible approach to the environment is to increase the use of by-products of one industry which is disposed off as waste as row material for some other industry developed countries have made rapid strides in the utilization of supplementary Cementitious material in cement and concrete. lack of awareness, consumer preferences, negative marketing strategies & Lot of missunderstanding among the people have impeded their utilization in our country. In this work I have chosen fly ash for blending with Portland cement Viz. Fly ash. This waste after grinding properly was blended with ordinary Portland cement in different proportions. Then that blended cement was tested for various properties of cements such as fineness, Standard Consistency, Soundness, Setting time & Compressive Strength. As the waste in powder form is of cementitious materials, they are proved to be best when blended with cement. I have got improved results related to most of the properties of cement as compared to that of ordinary Portland Cement. As industrial wastes pose a big problem of their disposal such waste can be blended with cement, bringing economy in Construction industry. So such waste can be blended with Cement, is the step towards economy & obviously towards progress of the nation.
