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.
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.
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.
The Hanzehogeschool Groningen (HUAS hereafter) is a University of Applied Sciences that is strongly inspired by the challenges of the North Netherlands region and firmly embedded in the city of Groningen in particular. HUAS has a strong track record in education, and practice-based research, and is dedicated to enhancing innovation and entrepreneurship. HUAS currently has 31,000 students Bachelor and Master students in 70 teaching programs. The 3.000 member of staff forming 17 schools and 7 centres of applied research collaborate to offer a cutting-edge teaching-based research. HUAS took the challenge to develop a strong research capacity with 67 professors, and an increasing number of researchers at various levels, supported by dedicated technical and administration support staff. PhD research thesis are co-supervised in collaboration with various universities in the Netherlands and abroad. HUAS positions itself as an Engaged and Versatile university, both in education and research. In line with this, the overall strategic ambitions of HUAS are to develop suitable learning pathways with recognised qualifications; to conduct applied research with a visible impact on education and society; and to be an adaptive, versatile and approachable organisation. HUAS links these strategic ambitions to three strategic research themes: Energy, Healthy Ageing and Entrepreneurship and four societal themes: strengthening a liveable and sustainable North Netherlands; transition to a healthy and active society; digital transformation; and energy transition and circularity. These four challenges define the focus of HUAS education and research.One of the societal themes is explicitly linked to the region: strengthening a liveable and sustainable North Netherlands. North Netherlands is a powerful, enterprising region with the city of Groningen as the healthiest city in the Netherlands. The region is a front runner in the energy transition, has a European exemplary role in the field of active and healthy ageing, and as an agricultural region, has many opportunities for the development of the circular economy and consequently the development of biobased construction material to mitigate climate change. Cooperation with different groups and stakeholders in the region is central in HUAS’s strategy. HUAS is part of extensive local and regional networks, including the University of the North and Akkoord van Groningen. As such, HUAS is well- connected to the research ecosystem in North Netherlands.HUAS has the ambition to better align, connect & develop on a local as well as a regional, national and international levels. Many of the challenges the North is faced with are also relevant in the EU context. Therefore, HUAS is a strong advocate and actor on engaging in European projects. HUAS monitors regularly the EU’s priorities and aligns its research between these priorities and its immediate societal needs. The EU provides a range of funding opportunities that fulfil our ambition as a research and teaching university and responds directly to our challenges from social, energy, and digital transformation. Indeed, over the last decade, HUAS has been successful in European programmes. In the Horizon 2020 programme, HUAS was part of five approved projects. In Horizon Europe so far two projects were granted. HUAS has performed particular well in the EU societal challenge for a secure, clean and efficient energy system. Examples of this are Making City (https://makingcity.eu/) focussing on the developing Positive Energy Districts, and IANOS (https://ianos.eu/) about the decarbonisation of islands. In addition to EU research and innovation schemes, HUAS has a considerable track record in projects funded by the Interreg schemes. In particular, these types of projects have strong links with region, and partners in the region. Currently, EU participation and involvement of HUAS is mainly concentrated in one field: sustainability & energy. In order to further disseminate to other parts of the university, only a well-designed strategy will allow the various research centres to better reach European fundings and satisfy the university’s ambitions. However, so far, no structured mechanism is in place internally to guide the research community and regional stakeholders how to reach European collaboration with confidence. Therefore, this pilot project aims to develop a strategic framework to enhance the participation of all parties at HUAS, including a pilot project that will lead to improvement and validation.
