This first publication of the CBCI project (Circular Bio-based Construction Industry) is a practical guide aimed at real estate professionals, (public) property owners and developers. This White Paper will discuss some of the challenges surrounding bio-based and circularity such as; price competition from virgin material alternatives, confidence in quality, hazardous material substance (when reusing in a circular context), lack of existing building data as well as the time delay between building and deconstruction. Next to this, the White Paper aims to illustrate how one could be more successful at taking circular and bio-based construction initiatives. The learnings from interviews and desk research are put together in five essentials, which are explained and illustrated by insights, exemplary projects (case studies) and readily applicable solutions. These five essentials form the outline of this White Paper: 1. AFFORDABLE cost-effective & inclusive reuse, 2. FLEXIBLE prepare for future functions, 3. PASSIVE stay cool & healthy with bio-based materials, 4. INTEGRAL continuously reflect on circular bio-based benefits & 5. TRADITIONAL OWNERSHIP keep it, simple. The thirteen exemplary cases explored for the creation of this White Paper show that it is possible to adopt circular and bio-based construction initiatives. However, it is not always easy and requires perseverance as well as leadership. Therefore, the five essentials and cases in this white paper can be used as inspiration and could help real estate professionals, property owners, developers and other interested parties in the construction sector to realise affordable and feasible circular bio-based constructions. By focusing on the essentials, one could prevent valuable resources (including energy) going to waste, today and in the future.

Circular, biobased, and modular construction practices are gaining traction as cities seek to reduce the environmental impact of the built environment. However, little is known about how these strategies affect construction logistics and their associated emissions. We develop an agent-based model to assess the environmental and spatial impacts of construction logistics in the Amsterdam Metropolitan Region (AMA) under six future scenarios. These scenarios vary in transport modes, construction practices, and logistics hub configurations. Results show that modular construction significantly reduces emissions through delivery consolidation, while circular and biobased approaches present trade-offs. Circular logistics reduce total emissions by sourcing materials locally but increase local emissions and congestion due to more frequent, short-distance trips in case of fossil transport. Biobased construction reduces transport emissions because of lower weight but may increase emissions when materials are sourced from distant suppliers, often located abroad, e.g. in Austria. The study also reveals that water transport lowers CO₂ but often raises NOₓ and PM emissions in case of use of ships with older engines. Also, decentralized logistics networks may perform worse than centralized ones without advanced coordination. These findings emphasize that sustainability benefits depend not just on what is built, but how and where materials are transported. Policymakers and urban planners must weigh both global and local trade-offs when designing logistics systems for sustainable construction. Our model offers a data-driven framework to support such decisions, highlighting the need for integrated, spatially grounded planning approaches in the circular transition.

Worldwide, plastic cups are used for serving drinks. Some typical examples of large-scale consumption are large concerts and festivals. As a part of the BIOCAS project, which focusses on the valorization of biomass through various routes, a PHA biobased festival cup was developed and created to reduce the impact of current fossil plastics. The role of VHL was to assess the environmental impact. The aim of the report is to inform the BIOCAS-partners about the use of plastic cups, and address the environmental impact in comparison with other types of biobased plastic cups and fossil-based cups. This report can serve as a basis for making choices within all different types of (plastic/biobased) cups. Besides, it can be used as a public communication tool about the environmental impact of different types of (plastic/biobased) cup applications.

Om de toepassing van biobased plastics te stimuleren is een belangrijke rol weggelegd voor ontwerpers. Omdat zowel gevestigdeontwerpers als studenten weinig tot geen kennis hebben van biobased plastics, doet de Hogeschool van Amsterdam (HvA) onderzoek naar verschillende aspecten van ontwerpen met biobased plastics.

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).

Dit boekje is een weerslag van de inaugurele rede als Lector Biobased Economy bij Hogeschool Van Hall Larenstein die Hans Derksen op 8 mei 2012 hield. De kern van het betoog is wat de biobased economy kan betekenen voor een duurzame samenleving. Maar ook wat deze niet kan betekenen, want biomassa is niet de oplossing voor alles. Uiteindelijk gaat het vooral over de kansen die biomassa, en meer in het bijzonder een biobased economy, de mens biedt.

This paper shows how locally available biomass is used to its full potential as source for renewable energy and bio-based products with a multidimensional integrated approach. The use of locally available biomass streams, which are currently hardly or not optimally used, is the center of the project Energy Conversion Parks (ECP). In this work we show the project results for the municipality of Breda, in the southern part of the Netherlands. The ECP developed for this municipality combines anaerobic digestion of various biomass streams, use of waste heat in biogas installations, and use of biogas output for several purposes (heat, electricity, green gas and liquid bio-methane). Models have been developed to quantify the production of various energy vectors as a function of inputs. Moreover, choices can be made about the inputs and outputs, allowing to vary the quantities produced. The models can also calculate the internal rate of return and influence of subsidies for the different process configurations.

Door de ondertekening van het klimaatakkoord van Parijs hebben overheden beleid ontwikkeld om de voorziene opwarming van het klimaat te beperken. Voor de bouwsector gaat het dan vooral om zuinig omgaan met grondstoffen en minder energieverbruik in de productie en het gebruik van gebouwen. Om de doelstellingen van het akkoord van Parijs te behalen, is een andere opvatting over het economische model ontstaan: de circulaire economie, als tegenhanger van de huidige gangbare lineaire economie. De wet- en regelgeving volgt deze ontwikkeling, maar dat is pas sinds kort. Er is veel in beweging. In deze whitepaper schetsen wij de ontwikkelingen in de wet- en regelgeving voor een circulaire bouwsector. Eén van de ontwikkelingen is een grotere rol voor hernieuwbare materialen en producten in die toekomstige economie. Deze whitepaper geeft antwoord op verschillende vraagstukken: • Welke wet- en regelgeving is belangrijk voor opschaling van circulair biobased bouwen? • Wat is te leren van het verschil in aanpak tussen de betrokken landen? • Hoe belemmerend is wet- en regelgeving nu écht? • Hoe flexibel is wet- en regelgeving in het kader van functieverandering? • Hoe groot is de ruimte voor het stimuleren van circulair biobased bouwen binnen de wet- en regelgeving?
