Structuring Knowledge

While participation in environmental decision-making is widely recognised and valued in democratic countries as beneficial, its format and scope have not always been the source of agreement. The use of environmental systems assessment (ESA) offers the opportunity for structuring knowledge and decision-making systematically and appropriately to decision makers' concerns, to enable lay publics to participate in development of policy and implementation in public sector initiatives. In order to perform participatory ESA, effective means of involving lay people are required. This paper describes the development and testing of an innovative interactive multimedia package (WOMBLE), written for non-experts to enable them to use the expert tool WISARD, a quantitative life cycle assessment package, to enable involvement in developing and assessing options for management of Municipal Solid Waste (MSW). It was shown that this combination of tools can reduce the time needed to achieve effective communication, learning and active engagement.

Demolition Waste

The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction and demolition waste (C&Dw). Unfortunately, even today, the majority of this waste ends up underexploited and not considered as valuable resources to be re-circulated into a closed/open loop process under the umbrella of circular economy (CE). Considering the amount of virgin aggregates needed in civil engineering applications, C&Dw can act as sustainable catalyst towards the preservation of natural resources and the shift towards a CE. This study completes current research by presenting a life cycle inventory compilation and life cycle assessment case study of two buildings in France. The quantification of the end-of-life environmental impacts of the two buildings and subsequently the environmental impacts of recycled aggregates production from C&Dw was realized using the framework of life cycle assessment (LCA). The results indicate that the transport of waste, its treatment, and especially asbestos’ treatment are the most impactful phases. For example, in the case study of the first building, transport and treatment of waste reached 35% of the total impact for global warming. Careful, proactive, and strategic treatment, geolocation, and transport planning is recommended for the involved stakeholders and decision makers in order to ensure minimal sustainability implications during the implementation of CE approaches for C&Dw.

Construction Product

This paper introduces the need for the responsible selection of construction products and then analyses a number of assessment methodologies. Some computer packages and guidebooks that assist in life cycle assessment or aid construction product selection are briefly reviewed. Issues that affect decision-making and complexities in the construction industry are discussed. A tool for assisting responsible construction product selection is then presented that involves carrying out a streamlined life cycle assessment, comparing a novel product to a traditional product. The tool is pragmatic because only three environmental criteria are considered (resource consumption, energy use and human and ecological impacts) and a relative rather then absolute assessment is required. The decision-assisting methodology is demonstrated with a case study. The limitations and benefits of the streamlined LCA are finally presented.
