Strategies for a Circular Economy in the Construction and Demolition Sector: Identifying the Factors Affecting the Recommendation of Recycled Concrete

Claudia Rebeca Binder Signer, Ralph Hansmann, Ivo Philippe Baur, Valeria Superti, Cynthia Houmani

With increasing urbanisation, new approaches such as the Circular Economy (CE) are needed to reduce resource consumption. In Switzerland, Construction & Demolition (C&D) waste accounts for the largest portion of waste (84%). Beyond limiting the depletion o ...

Decision Framework to Balance Environmental, Technical, Logistical, and Economic Criteria When Designing Structures With Reused Components

Corentin Jean Dominique Fivet, Numa Joy Bertola, Jan Friedrich Georg Brütting, Célia Marine Küpfer

The reuse of structural components in new buildings has great potential to reduce the environmental impacts of the construction sector but remains uncommon practice. An obstacle to its wider implementation is the lack of robust assessment methods and decis ...

Comparison of environmental assessment methods when reusing building components: a case study

Corentin Jean Dominique Fivet, Endrit Hoxha, Catherine Elvire L. De Wolf

The building industry is responsible for 35% of all solid waste in Europe and more than a third of greenhouse gas (GHG) emissions. To address this, applying circular economy principles to the building sector is crucial, for example by reusing building elem ...

Optimum design of frame structures from a stock of reclaimed elements

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

This paper presents optimization methods to design frame structures from a stock of existing elements. These methods are relevant when reusing structural elements over multiple service lives. Reuse has the potential to reduce the environmental impact of bu ...

Critical overview of biomass feedstocks as sustainable substrates for the production of polyhydroxybutyrate (PHB)

Edgard Gnansounou

Polyhydroxybutyrates (PHBs) are a class of biopolymers produced by different microbial species and are biodegradable and biocompatible in nature as opposed to petrochemically derived plastics. PHBs have advanced applications in medical sector, packaging in ...

Hybrid Transcriptional Regulators for the Screening of Target DNA Motifs in Organohalide-Respiring Bacteria

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin, Marie Vingerhoets

The bioremediation of persistent organohalide molecules under anoxic conditions mostly relies on the bacterial process called organohalide respiration (OHR). Organohalide-respiring bacteria (OHRB) are phylogenetically diverse anaerobic bacteria that share ...

Optimum design of low environmental impact structures through component reuse

Jan Friedrich Georg Brütting

Load-bearing systems (structures) in buildings and infrastructure contribute to a significant share of adverse environmental impacts (EI) because of resource- and energy-intensive fabrication. A currently overlooked circular economy strategy to reduce EI i ...

Environmental impact minimization of reticular structures made of reused and new elements through Life Cycle Assessment and Mixed-Integer Linear Programming

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

An important share of building environmental impacts is embodied in load-bearing structures because of their large material mass and energy-intensive fabrication process. To reduce substantially material consumption and waste caused by the construction ind ...

Exploration of spatial structures made from reused elements and the design of optimal kits-of-parts

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

Reuse reduces raw material use, waste generation and energy consumption caused by building construction. A substantial share of these impacts is contributed by load-bearing systems be-cause of their mass- and energy-intensive production process. Therefore, ...

Form follows availability – Designing structures through reuse

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Gennaro Senatore

This work proposes a new direction in structural design: the synthesis of structures through the reuse of elements. Reusing structural elements reduces the environmental impacts of building structures because it avoids sourcing new material, it reduces was ...
