This paper presents work aimed at improved organization and performance of production in housing renovation projects. The purpose is to explore and demonstrate the potential of lean work organization and industrialized product technology to improve workflow and productive time. The research included selected case studies that have been found to implement lean work organization and industrialized product technology in an experimental setting. Adjustments to the work organization and construction technology have been implemented on site. The effects of the adjustments have been measured and were reviewed with operatives and managers. The data have been collected and analyzed, in comparison to traditional settings. Two projects were studied. The first case implied am application of lean work organization in which labor was reorganized redistributing and balancing operations among operatives of different trades. In the second case industrialized solution for prefabricated installation of prefabricated roofs. In both cases the labor productivity increased substantially compared to traditional situations. Although the limited number of cases, both situations appeared to be representative for other housing projects. This has led to conclusions extrapolated from both cases applicable to other projects, and contribution to the knowledge to improve production in construction. Vrijhoef, R.

In reflecting on Dutch Christmas shoppers, this article will discuss environmental Kuznets curve (EKC), postmaterialist values hypothesis, and ecological modernization theory. According to the EKC hypothesis, while at the initial stages of industrialization material resources are often used unsustainably, continuing industrialization leads to a threshold after which lead to progressively more sustainable technologies. According to the postmaterialist values hypothesis, only wealthier societies can ‘afford’ to care about the environment, assuming that wealth will lead to development of greater concern about and valuation of environment. Finally, ecological modernization theory postulates that environmental conditions improve with advanced technological development and suggests that enlightened self-interest, economy and ecology can be favourably combined and that productive use of natural resources can be a source of future growth. In generalizing economic, political and social trends in relation to consumption in The Netherlands, the aim of this article is to consider the consequences of Western-style consumption for the enterprise of global development. https://doi.org/10.1016/j.scs.2013.05.004 https://www.linkedin.com/in/helenkopnina/

Het Nederlands Openluchtmuseum (NOM) wil actief bijdragen aan een duurzame samenleving met zijn kennis van materialen, producten, diensten en culturele tradities die eeuwenlang functioneerden binnen circulaire gemeenschappen. Ondanks technologische vernieuwing en globalisering heeft het NOM de overtuiging dat deze historische kennis kan bijdragen aan duurzame producten voor de toekomst. Het NOM wil een structurele samenwerking met de creatieve sector om meetbare impact te realiseren binnen en buiten het museum voor de transitie naar een circulaire samenleving. Daarvoor wil het graag zijn collectie en kennis toegankelijk maken voor ontwerpers. Belangrijke praktijkvragen daarbij zijn: Welke rol kan het museum spelen i.s.m. ontwerpers? Hoe kan relevante kennis van het NOM toegankelijk en toepasbaar worden gemaakt voor ontwerpers? Hoe creëer je samen met ontwerpers de gewenste impact in de samenleving? Op basis hiervan is de onderzoeksvraag geformuleerd: Hoe kunnen maatschappelijke organisaties zoals het NOM relevante kennis en artefacten toegankelijk en toepasbaar maken voor ontwerpers t.b.v. meetbare impact voor een circulaire samenleving? Deze onderzoeksvraag is vertaald naar enkele sub-vragen over definities van duurzaamheid en circulariteit, de verwachte rollen van museum en ontwerpers, de gewenste structuur van samenwerking en over de rol van prototypen om de gewenste impact te realiseren. Naast het NOM als MKB, participeren in dit project twee creatieve ondernemers (1 MKB, 1 ZZP-er) die zijn geselecteerd op basis van hun specifieke ontwerpkwaliteiten, hun ervaringen in samenwerken met partners en hun kennis van circulair ontwerp. Samen met docent-onderzoekers en ontwerpstudenten van ArtEZ onderzoeken zij deze vragen. De belangrijkste projectresultaten zijn: prototypen, getest op gewenste maatschappelijke impact; een rapport dat beschrijft hoe het NOM kan samenwerken met de creatieve sector om bij te dragen aan ‘Nederland circulair’; en presentatie- en netwerkbijeenkomsten om kennis te delen en te bouwen aan het netwerk van stakeholders om beoogde impact te realiseren.
Human kind has a major impact on the state of life on Earth, mainly caused by habitat destruction, fragmentation and pollution related to agricultural land use and industrialization. Biodiversity is dominated by insects (~50%). Insects are vital for ecosystems through ecosystem engineering and controlling properties, such as soil formation and nutrient cycling, pollination, and in food webs as prey or controlling predator or parasite. Reducing insect diversity reduces resilience of ecosystems and increases risks of non-performance in soil fertility, pollination and pest suppression. Insects are under threat. Worldwide 41 % of insect species are in decline, 33% species threatened with extinction, and a co-occurring insect biomass loss of 2.5% per year. In Germany, insect biomass in natural areas surrounded by agriculture was reduced by 76% in 27 years. Nature inclusive agriculture and agri-environmental schemes aim to mitigate these kinds of effects. Protection measures need success indicators. Insects are excellent for biodiversity assessments, even with small landscape adaptations. Measuring insect biodiversity however is not easy. We aim to use new automated recognition techniques by machine learning with neural networks, to produce algorithms for fast and insightful insect diversity indexes. Biodiversity can be measured by indicative species (groups). We use three groups: 1) Carabid beetles (are top predators); 2) Moths (relation with host plants); 3) Flying insects (multiple functions in ecosystems, e.g. parasitism). The project wants to design user-friendly farmer/citizen science biodiversity measurements with machine learning, and use these in comparative research in 3 real life cases as proof of concept: 1) effects of agriculture on insects in hedgerows, 2) effects of different commercial crop production systems on insects, 3) effects of flower richness in crops and grassland on insects, all measured with natural reference situations
The global market for colorants is projected to reach €86.76 billion by 2030, with the majority of these colorants derived from non-renewable petroleum. The production process of synthetic colorants and its residuals can cause significant problems to environment and health. In light of these concerns, there is growing interest in natural colorants as a sustainable alternative. Fungal colorants are one of the promising candidates. Historically fungal colorants have been used for various purposes. However, the industrial productivity, scalability, and application possibilities of fungal colorants are yet to be fully explored. Many Dutch small and medium-sized enterprises (SMEs) are particularly interested in fungal colorants, but the limitation of experiences and knowledge in these novel products creates a gap among research, commodity, and markets. To fill this gap, it is essential to explore fungal colorant production from both technical and economic angles. This means a multidisciplinary approach would be needed including fermentation yield improvements, extraction upscaling and application discovery. These approaches require specific expert knowledge and facilities which are not easily accessible to SMEs. Therefore, by combining the expertise of 2 universities of applied sciences, 1 academic institute, 8 SME and 2 branch organizations, the TUFUCOL consortium proposes to conduct sets of studies contributing to fungal colorant industrialization in this project. The consortium will focus on blue and orange colorants produced by two different fungi as prototypes, and will conduct scaling-up and non-food application tests in industrial settings.The results will help to estimate the technological and economic potential of fungal colorants as a sustainable alternative to current synthetic sources. The development of a prototype fungal colorant business case could benefit achieving the climate neutral goal by reducing the reliance on non-renewable resources and reducing environmental pollution. This will contribute to the transition towards a circular economy.
