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.

Since 2016, the Amsterdam Dapperbuurt in the East of Amsterdam, has its own Zero Waste Lab (ZWL), a collection and recycle centre for separated household waste. Drawing on the specific case of wood as a waste-stream, the project Circulair Wood for the Neighbourhood supports the ZWL (initiative of the foundation De Gezonde Stad) realizing two of their ambitions: (A) to transition from recycling to up-cycling; (B) to transition from awareness raising to social engagement and shared ownership. The project is a partnership between the ZWL, the Amsterdam University of Applied Sciences (Research Group Psychology for Sustainable Cities & Research Group Digital Production) and Verdraaid Goed (a Rotterdam based company up-cycling devalued materials by research and design). The project Circulair Wood for the Neighbourhood contains three components/sub-projects, 1) research on the wood waste stream and possibilities for production; (2) research on design possibilities, and (3) research on stakeholder involvement. This is the final report of the sub-project stakeholder involvement led by the research group Psychology for Sustainable Cities. This sub-project specifically examined the psychology behind the decision making process of residents to hand in (or not) separated household wood waste to the ZWL in the neighbourhood of the Dapperbuurt and proposes possible interventions.
Growing volumes of wood are being used in construction, interior architecture, and product design, resulting in increasing amounts of wood waste. Using this waste is challenging, because it is too labor-intensive to process large volumes of uneven wood pieces that vary in geometry, quality, and origin. The project “Circular Wood for the Neighborhood” researches how advanced computational design and robotic production approaches can be used to create meaningful applications from waste wood. shifting the perception of circular wood as a simply harvested stream, towards a material with unique aesthetics of its own right. The complexity of the material is suggested to be tackled by switching from the object-oriented design towards designing soft systems. The system developed uses a bottom-up approach where each piece of wood aggregates according to certain parameters and the designed medium is mainly rule-sets and connections. The system is able to produce many options and bring the end-user for a meaningful co-design instead of choosing from the pre-designed options. Material-driven design algorithms were developed, which can be used by designers and end-users to design bespoke products from waste wood. In the first of three case studies, a small furniture item (“coffee table”) was designed from an old door, harvested from a renovation project. For its production, two principle approaches were developed: with or without preprocessing the wood. The principles were tested with an industrial robotic arm and available waste wood. A first prototype was made using the generated aggregation from the system, parametric production processes and robotic fabrication.
In Amsterdam's neighbourhoods, much of the waste that is disposed has the potential of becoming something else by means of recycling or upcycling. Zero Waste lab –which is part of the organization De Gezonde Stad- is a place where inhabitants can bring their own separated waste in exchange for value coins. Now, Zero Waste Lab now wants to take this a step forward and further develop their own project: from recycling to upcycling waste. In this endeavour, HvA will collaborate by researching the possibilities for upcycling a local waste stream by means of digital production pro-cesses, as well as ways of involving the neighbourhood. Because it is of vital importance for the project not only to be technically possible, but also scalable and economically feasible, Zero Waste Lab and HvA have asked for partnership to the company Verdraaid Goed. This partnership and specific case study, presented here as ‘Wood for the neighborhood’ can be summa-rized in four main goals: • (Production) Explore the design and manufacturing possibilities of using digital production to upcycle a local wood waste stream (with an industrial robotic arm) • (Design) Show how explorative research, when carried on from the beginning of the de-sign process, can bring great added value to the development of project concepts. • (Social) Demonstrate that involving stakeholders early in the process of reusing and de-signing with waste materials can shape the future in new directions • (All three) Highlight how this case study is relevant and fits the principles of the circular economy
Professionals van woningbouwcorporaties en gemeentes die zich bezig houden met verduurzaming hebben vragen over hergebruik van afvalhout uit hun (renovatie) projecten. De doelstelling van dit voorstel is het onderzoeken van de mogelijkheden om hout te hergebruiken door gebruik te maken van innovatieve digitale productietechnieken, en om implementatiestrategieën hiervoor te ontwikkelen voor publieke organisaties in de bouwsector, in het bijzonder woningcorporaties en gemeentes. Strategieën omvatten concrete voorstellen om a) afvalhout van woningen in te zamelen en te verwerken; b) waarde toe te voegen aan houtafvalstromen door middel van digitale productie; c) de betrokkenheid en acceptatie van huurders te vergroten bij circulaire verwerking van hout in nieuwe toepassingen; en d) goede toepassingen voor een circulaire economie te realiseren. Het project onderzoekt aard en omvang van houtafvalstromen uit woningrenovatie en identificeert de mogelijkheden voor het hergebruik van specifieke fracties daarvan voor (lokale) toepassingen. Uit voorgaande projecten blijkt dat digitale productie mogelijkheden biedt om stedelijk afval om te zetten in zinvolle circulaire producten. Digitale productie maakt de (lokale) creatie van unieke prototypen en grootschalige toepassingen mogelijk. Het onderzoek wordt uitgevoerd in vier werkpakketten. De eerste identificeert de aard van huishoudelijk houtafval (volume, houtsoort, verzamelproces) door zorgvuldig cases van Ymere en Rochdale te bestuderen. Daarnaast worden er een raamwerk van indicatoren gedefinieerd om projectresultaten te kunnen evalueren. Het tweede werkpakket onderzoekt welke toepassingen kunnen worden bedacht, gegeven de beschikbare houtfracties. In het derde werkpakket wordt een aantal case studies uitgevoerd voor concrete projecten van de deelnemende woningcorporaties. Deze applicaties hebben als doel het potentieel van digitale productie met houtafval te laten zien, rekening houdend met het perspectief van bewoners. Het biedt belangrijke inzichten in de uitvoerbaarheid van concrete toepassingen uit teruggewonnen hout. In het vierde werkpakket worden alle projectbevindingen gecombineerd in een set implementatie strategieën voor publieke organisaties in het stedelijk domein.
