Project Abstract

Nature presents us with magnificent examples of cycles, where abundant nutrients and water are continually reused, with the remnants becoming immediate resources for others. Despite these awe-inspiring examples existing for centuries, humans persist in the linear "make, use, dispose" approach. Fortunately, a shift has begun with the concept of the circular economy, aiming to close loops and transform goods near the end of their service life into resources for others. The correct adoption of the circular economy yields immediate positive effects, ranging from reducing greenhouse emissions to fostering workforce growth. The notion of the circular economy has evolved beyond the simple idea of reusing and recycling materials. It now encompasses sustainable economic growth and positive impact on our environment through resource optimization and consumption efficiency. Essentially, the circular economy is a means to achieve sustainable development. This transition has necessitated changes in production chains and consumption models, leading to the redesign of industrial systems. While the circular economy has gained traction in certain industries like clothing, it is now being actively promoted in other sectors, including remanufacturing in the fields of computers, electronics, optics, and electrical equipment. Extracting, processing, producing, and consuming materials and products are responsible for a significant share of greenhouse gas emissions, accounting for a quarter in Europe and a third globally. The construction sector, in particular, stands to gain immense benefits from embracing circular economy practices. Recognising that construction, renovation, deconstruction, and demolition activities contribute significantly to embodied carbon emissions, which amounted to 3.67 million tonnes of carbon dioxide globally in 2019, addressing this issue becomes paramount. The construction sector heavily relies on carbon-intensive building materials. In the REBUILD project, our goal is to reimagine buildings as material banks and investigate the implications of reusing, optimising, changing, and testing a diverse range of building materials. This project aims to catalyse a breakthrough for the circular economy in the construction sector by addressing key challenges prevalent in current construction practices across three main areas. Firstly, we will strive to understand the primary barriers hindering the sector's transition to circular economy practices. Secondly, we will identify the key enablers that will facilitate the shift from passive linear economy practices to circular economy practices within the construction sector. Lastly, we will delve into studying the implications of adopting circular economy activities in construction, including estimating potential carbon emissions savings and examining the consequences of reducing the exportation of building materials that are currently designated for treatment. The methodologies employed in this project extend beyond the construction sector, contributing to the wider adoption of circular economy practices in other domains. As a holistic concept, the project will benefit society economically, socially, and environmentally. Economically, this project will contribute to Irish competitiveness by optimising the utilisation and allocation of materials. Environmentally, it will naturally reduce negative impacts on the environment, such as carbon emissions saved by making the range of selected materials more circular. Socially, the project will pave the way to create additional employment opportunities and promote social inclusion.
