The title of this dissertation is Armchair travelling the innovation journey. ‘Armchair travelling’ is an expression for travelling to another place, in the comfort of one’s own place. ‘The innovation journey’ is the metaphor Van de Ven and colleagues (1999) have used for travelling the uncharted river of innovation, the highly unpredictable and uncontrollable process of innovation. This research study began with a brief remark from an innovation project leader who sighed after a long and rough journey: ‘had I known this ahead of time…’. From wondering ‘what could he have known ahead of time?’ the immediate question arose: how do such innovation journeys develop? How do other innovation project leaders lead the innovation journey? And could I find examples of studies about these experiences from an innovation project leader’s perspective that could have helped the sighing innovation project leader to have known at least some of the challenges ahead of time? This dissertation is the result of that quest, as we do know relatively little how this process of the innovation project leader unfolds over time. The aim of this study is to increase our understanding of how innovation project leaders lead their innovation journeys over time, and to capture those experiences that could be a source for others to learn from and to be better prepared. This research project takes a process approach. Such an approach is different from a variance study. Process thinking takes into account how and why things – people, organizations, strategies, environments – change, act and evolve over time, expressed by Andrew Pettigrew (1992, p.10) as catching “reality in flight”.

Traditionally construction industries in New Zealand and abroad have a low track record for successful sustainable innovations. This has a negative impact on private and government spending, and on quality, society and the environment. This conceptual paper posits that the construction industry needs non-incremental (i.e. architectural, system, radical, modular) sustainable technology innovations to make drastic improvements. Such innovations often come from entrepreneurial (small) firms from other industries or at the beginning of supply chains and must be procured and adopted further into such chains. However, after an extensive literature review it remains unclear how entrepreneurial firms procure non-incremental sustainable technology innovations for the construction industry. The paper focuses on procurement activities of entrepreneurial firms in the New Zealand context. These activities interact with (internal and external) innovation activities for an optimal firm performance. They are affected by clusters of internal and external variables.The paper discusses extant literature, a conceptual framework, main propositions, research aims and the choice for a focus group method. It is part of a doctoral project.Paper, presented at ACERE 2015 in Adelaide Australia.
The research concerned semi-dyadic relations in SMEs and large companies that managed innovative suppliers in New Zealand construction supply chains. It explored effects of (independent) company variables on (mediating) procurement management variables, and also the effects of these variable types on (dependent) procurement performance variables when managing innovative suppliers.Exploratory interviews (N=5) revealed that innovation procurement seemed professional and logical within their contexts.Survey I (N=112) revealed that most case companies followed a product leadership strategy, and were equally entrepreneurial to innovative customers and innovative suppliers. They were innovative and gave innovative suppliers a dominant innovation role. They seemed to prefer radical innovations less than incremental innovations, but still somewhat more than New Zealand averages. Companies had slight preferences for new, small, or foreign suppliers for radical innovations. Innovations with supplier interactions were more beneficial to the company and the natural environment, than innovations without supplier interactions. Higher company innovation-benefits could equal higher environmental innovation-benefits. This profile differed from the profile of average companies in the construction supply chain.Survey I found weak correlations among output performance variables and process or proxy performance variables.Dependent (procurement and performance) variables were affected differently. Conversely, independent (company and procurement) variables had different effects.Different from extant literature, Survey I found limited statistically-significant effects of company variables on procurement management variables, and of these two variable types on performance. A minority (41%) of company variables affected procurement variables; only two company variables (13%) affected performance; a minority (40%) of procurement variables affected performance.Product leadership and NPD/innovation experience affected performance. Moreover, trust, lifestyle strategies and survival strategies affected procurement variables. Conversely, 27% of performance variables (satisfaction on marketing & sales; benefits for the natural environment) and 30% of procurement variables (entrepreneurial orientation with innovative suppliers, relation intensity with manufacturers, and small vs large suppliers for radical innovations) responded stronger on some company variables. Company size (<99 versus >250 staff) had little effects.Innovating, opportunity-seeking and trust towards innovative suppliers, and relation intensity with innovative service providers had highest effects on performance. Conversely, 46% of the performance variables (satisfaction with innovative suppliers, benefits for natural environment and company) responded stronger on innovating, opportunities-seeking and trust variables.Survey II (N=33) identified 12 procurement best-practices that respondents used for specific supplier or innovation types.Causality should be treated cautiously. Findings reflected the inconclusive results from extant literature. The research provided a nuanced and varied understanding on management of innovative suppliers, on the effects of entrepreneurial orientation to innovative suppliers, on the limited effects of company size, on the complex relations between various performance measures, and on entrepreneurship as a theoretical lens in innovation procurement. Companies had several options on how they managed their innovative suppliers. Additionally, the company characteristics and context of in this nascent research domain could be more important than commonly assumed from extant research.

Buildings are responsible for approximately 40% of energy consumption and 36% of carbon dioxide (CO2) emissions in the EU, and the largest energy consumer in Europe (https://ec.europa.eu/energy). Recent research shows that more than 2/3 of all CO2 is emitted during the building process whereas less than 1/3 is emitted during use. Cement is the source of about 8% of the world's CO2 emissions and innovation to create a distributive change in building practices is urgently needed, according to Chatham House report (Lehne et al 2018). Therefore new sustainable materials must be developed to replace concrete and fossil based building materials. Lightweight biobased biocomposites are good candidates for claddings and many other non-bearing building structures. Biocarbon, also commonly known as Biochar, is a high-carbon, fine-grained solid that is produced through pyrolysis processes and currently mainly used for energy. Recently biocarbon has also gained attention for its potential value with in industrial applications such as composites (Giorcellia et al, 2018; Piri et.al, 2018). Addition of biocarbon in the biocomposites is likely to increase the UV-resistance and fire resistance of the materials and decrease hydrophilic nature of composites. Using biocarbon in polymer composites is also interesting because of its relatively low specific weight that will result to lighter composite materials. In this Building Light project the SMEs Torrgas and NPSP will collaborate with and Avans/CoE BBE in a feasibility study on the use of biocarbon in a NPSP biocomposite. The physicochemical properties and moisture absorption of the composites with biocarbon filler will be compared to the biocomposite obtained with the currently used calcium carbonate filler. These novel biocarbon-biocomposites are anticipated to have higher stability and lighter weight, hence resulting to a new, exciting building materials that will create new business opportunities for both of the SME partners.
The Netherlands must build one million homes and retrofit eight million buildings by 2030, while halving CO₂ emissions and achieving a circular economy by 2050. This demands a shift from high-carbon materials like concrete—responsible for 8% of global CO₂ emissions—and imported timber, which inflates supply-chain emissions. Mycelium offers a regenerative, biodegradable alternative with carbon-sequestration potential and minimal energy input. Though typically used for insulation, it shows structural promise—achieving compressive strengths of 5.7 MPa and thermal conductivities of 0.03–0.05 W/(m·K). Hemp and other lignocellulosic agricultural byproducts are commonly used as substrates for mycelium composites due to their fibrous structure and availability. However, hemp (for e.g.) requires 300–500 mm of water per cycle and centralized processing, limiting its circularity in urban or resource-scarce areas. Aligned with the CLICKNL Design Power Agenda, this project explores material-driven design innovation through a load-bearing mycelium-based architectural product system, advancing circular, locally embedded construction. To reduce environmental impact, we will develop composites using regional bio-waste—viz. alienated vegetation, food waste, agriculture and port byproducts—eliminating the need for water-intensive hemp cultivation. Edible fungi like Pleurotus ostreatus (oyster mushroom) will enable dual-function systems that yield food and building material. Design is key for moving beyond a singular block to a full product system: a cluster of modular units emphasizing geometry, interconnectivity, and compatibility with other building layers. Aesthetic variation (dimension, color, texture) supports adaptable, expressive architecture. We will further assess lifecycle performance, end-of-(service)-life scenarios, and on-site fabrication potential. A 1:1 prototype at The Green Village will serve as a demonstrator, accelerating stakeholder engagement and upscaling. By contributing to the KIA mission on Social Desirability, we aim to shift paradigms—reimagining how we build, live, grow, and connect through circular architecture.
Lightweight, renewable origin, mild processing, and facile recyclability make thermoplastics the circular construction materials of choice. However, in additive manufacturing (AM), known as 3D printing, mass adoption of thermoplastics lags behind. Upon heating into the melt, particles or filaments fuse first in 2D and successively in 3D, realizing unprecedented geometrical freedom. Despite a scientific understanding of fusion, industrial consortium experts are still confronted with inferior mechanical properties of fused weld interfaces in reality. Exemplary is early mechanical failure in patient-specific and biodegradable medical devices based on Corbion’s poly(lactides), and more technical constructs based on Mitsubishi’s poly(ethylene terephthalate), PET. The origin lies in contradictory low rate of polymer diffusion and entangling, and too high rate of crystallization that is needed to compensate insufficient entangling. Knowing that Zuyd University in close collaboration with Maastricht University has eliminated these contradictory time-scales for PLA-based systems, Corbion and Mitsubishi contacted Zuyd with the question to address and solve their problem. In previous research it has been shown that interfacial co-crystallization of alternating depositioned opposite stereo-specific PLA grades resulted in strengthening of the interface. To promote mass adoption of thermoplastics AM industries, the innovation question has been phrased as follows: What is a technically scalable route to induce toughness in additively manufactured thermoplastics? High mechanical performance translates into an intrinsic brittle to tough transition of stereocomplex reinforced AM products, focusing on fused deposition modeling. Taking the professional request on biocompatibility, engineering performance and scalability into account, the strategies in lowering the yield stress and/or increasing the network strength comprise (i) biobased and biocompatible plasticizers for stereocomplexed poly(lactide), (ii) interfacial co-crystallization of intrinsically tough polyester based materials formulations, and (iii) in-situ interfacial transesterification of recycled PET formulations.
