Background and aim ʹ Many countries signed the Paris Agreement to mitigate global average temperature rise. In this context, Dutch government decided to realize a reduction of 50% using resources and raw materials in 2030. This paper explores how practice-based research into facility operations can contribute to this aim. Methods / Methodology ʹ Practice-based research which includes direct observations, desk research, and participatory action research. Results ʹ This explorative research presents principles and suggestions for facility managers and procurement managers on how they can embed sustainable materials management in the organisation and how to take control of waste. The proposed suggestions are derived from practice-based research and presented as topics of attention for facility professionals. Originality ʹ Within education of Dutch universities of applied sciences and daily professional facility practices, the phenomenon of materials management is underexposed. To contribute to the national and international climate objectives, (future) facility professionals need better support to reduce waste. Bachelor students were involved throughout this research. This approach gave refreshing insights into waste at the end of the supply chain (control separation units) that can improve informed decisionmaking at the beginning of the supply chain. Practical or social implications ʹ Facility management professionals have an important role to play in the mitigation of global average temperature rise, because of their leading role in procurement, service operations, and materials management. However, they struggle to find sustainable solutions. This paper seeks to inspire professionals with interventions that have proven effectiveness on the reduction of waste. Type of paper ʹ Short research paper.

In the housing market enormous challenges exist for the retrofitting of existing housing in combination with the ambition to realize new environmentally friendly and affordable dwellings. Bio-based building materials offer the possibility to use renewable resources in building and construction. The efficient use of bio-based building materials is desirable due to several potential advantages related to environmental and economic aspects e.g. CO2 fixation and additional value. The potential biodegradability of biomaterials however demands also in-novative solutions to avoid e.g. the use of environmental harmful substances. It is essential to use balanced technological solutions, which consider aspects like service life or technical per-formance as well as environmental aspects. Circular economy and biodiversity also play an im-portant role in these concepts and potential production chains. Other questions arise considering the interaction with other large biomass users e.g. food production. What will be the impact if we use more bio-based building materials with regard to biodiversity and resource availability? Does this create opportunities or risks for the increasing use of bio-based building materials or does intelligent use of biomass in building materials offer the possibility to apply still unused (bio) resources and use them as a carbon sink? Potential routes of intelligent usage of biomass as well as potential risks and disadvantages are highlighted and discussed in relation to resource efficiency and decoupling concept(s).

This study evaluates the effectiveness of the European Union's Corporate Sustainability Reporting Directive (CSRD) in quantitatively measuring the transition of companies to a circular economy. First, using the most recent literature review on circularity metrics, a complete overview of the currently available circularity metrics is developed. Subsequently, it is determined which circularity metrics can be generated with the available quantitative datapoints of CSRD. The metrics that can be generated were analyzed on their ability to cover all circular strategies, to represent different Product-as-a-Service systems and to acknowledge the key role of Critical Raw Materials in a circular economy. The study finds that, with data disclosed under CSRD, metrics can be generated to cover all circular strategies. However, gaps remain in representing pay-per-use and pay-perperformance systems and the use of Critical Raw Materials. Recommendations are to include ‘Product utilization’ and ‘Mass of Critical Raw Materials used’ in the data disclosed under CSRD and to have an independent institution report data to enable benchmarking of performances. Finally, this study concludes with an overview of the metrics which enable to measure circular transitions using data disclosed by CSRD

An important step towards improving performance while reducing weight and maintenance needs is the integration of composite materials into mechanical and aerospace engineering. This subject explores the many aspects of composite application, from basic material characterization to state-of-the-art advances in manufacturing and design processes. The major goal is to present the most recent developments in composite science and technology while highlighting their critical significance in the industrial sector—most notably in the wind energy, automotive, aerospace, and marine domains. The foundation of this investigation is material characterization, which offers insights into the mechanical, chemical, and physical characteristics that determine composite performance. The papers in this collection discuss the difficulties of gaining an in-depth understanding of composites, which is necessary to maximize their overall performance and design. The collection of articles within this topic addresses the challenges of achieving a profound understanding of composites, which is essential for optimizing design and overall functionality. This includes the application of complicated material modeling together with cutting-edge simulation tools that integrate multiscale methods and multiphysics, the creation of novel characterization techniques, and the integration of nanotechnology and additive manufacturing. This topic offers a detailed overview of the current state and future directions of composite research, covering experimental studies, theoretical evaluations, and numerical simulations. This subject provides a platform for interdisciplinary cooperation and creativity in everything from the processing and testing of innovative composite structures to the inspection and repair procedures. In order to support the development of more effective, durable, and sustainable materials for the mechanical and aerospace engineering industries, we seek to promote a greater understanding of composites.

This working paper is the introduction and exploration of the theme 'Value of waste' for the Energize festival 2015. What is the value of waste? Based on ideas concerning the lifecycle of materials it depends on where you are in this cycle: have you consumed material, then what remains is usually waste that has no value. But if the remains can function as raw materials for a product, then this same waste may turn out to be valuable. When you think in cycles like this, can you say that there is such a thing as waste at all? Or is ‘waste’ simply the stage in which materials are temporarily without value? And if so, who or what determines when something is waste?

From a circular standpoint it is interesting to reuse as much as possible construction and demolition waste (CDW) into new building projects. In most cases CDW will not be directly reusable and will need to be processed and stored first. In order to turn this into a successful business case CDW will need to be reused on a large scale. In this paper we present the concept of a centralized and coordinated location in the City of Utrecht where construction and demolition waste is collected, sorted, worked, stored for reuse, or shipped elsewhere for further processing in renewed materials. This has expected advantages for the amount of material reuse, financial advantages for firms and clients, generating employability in the logistics and processing of materials, optimizing the transport and distribution of materials through the city, and thus the reduction of emissions and congestion. In the paper we explore the local facility of a Circular Hub, and the potential effects on circular reuse, and other effects within the City of Utrecht.

Wood is an increasingly demanded renewable resource and an important raw material for construction and materials. Demands are rising, with a growing attention for re-use and upcycling. This opens opportunities for new business models, empowered by the use of digital design and technologies. A KPI-framework has thus been developed to assess the impact of waste wood upcycling, to provide new business perspectives. It is conceived as a tool to enable circular businesses to select the most appropriate circular wood applications for their portfolio. The framework currently consists of eight indicators addressing circularity, environment, society and economics. This paper presents these indicators and shares insights for further development and enhancement of the framework.

Green energy is just one of the two types of energy humanity needs, the energy for our man-made world, including cities, road networks, industries and technological systems (energy for the systems that drive out the ecology). However, a second type of energy is needed to meet our biological needs, energy from plant and or animal raw materials (from ecology). Green energy feeds the main competitor of ecology, our organistic source of energy. With the expansion of energy for unbridled technology, the imbalance between the man-made world and ecology will increase. Renewable energy is quickly running out at the expense of the ecological energy sources needed for life. It is argued that unless we control ourselves now, the imbalance between man-made (inorganic)systems and life (organic systems) will easily increase.
