Logistiek Biobased Economy: toekomstbeelden 2025 & agenda 2013-2017

Naast de afzetmogelijkheden van biobased producten (markten) en de technologische verwerkingsmogelijkheden, bepalen de beschikbaarheid, handel en logistiek in sterke mate de wijze waarop de biobased economy in Nederland zich zal ontwikkelen. Het is noodzakelijk in de komende jaren duurzame, economisch rendabele logistieke biomassaketens op te zetten. Op dit terrein bestaat nog veel onduidelijkheid. Het doel van het project is het vormen van: gedragen toekomstbeelden van de logistiek in de biobased economy in 2025 en een gedragen agenda met actiepunten voor 2013-2017 (ofwel waarmee moeten we starten in de eerstkomende 5 jaar om de toekomstbeelden te bereiken)

Practices and Obstacles to Provider-Initiated HIV Testing and Counseling (PITC) Among Healthcare Providers in Côte d’Ivoire

Practices of Provider-Initiated HIV Testing and Counseling (PITC) remains suboptimal in Côte d'Ivoire. The aim of this survey was to identify the practices and obstacles to PITC among healthcare professionals in Côte d'Ivoire. A nationally representative cross-sectional survey was conducted in 2018 by telephone among three separate samples of midwives, nurses and physicians practicing in Côte d'Ivoire. The number of HIV tests proposed during consultation in the month preceding the survey was collected for each professional. Factors associated with the number of proposed tests were identified through ordinal logistic regression models. A total of 298 midwives, 308 nurses and 289 physicians were interviewed. Midwives proposed the test more frequently, followed by nurses and physicians. Among midwives, a higher number of proposed tests was associated with the perception that HIV testing does not require specific consent compared to other diseases (aOR 4.00 [95% CI 1.37-14.29]). Among nurses, having received HIV training and the presence of community HIV counselors were associated with a higher number of proposed tests (aOR 2.01 [1.31-3.09] and aOR 1.75 [1.14-2.70], respectively). For physicians, the presence of a voluntary testing center was associated with a higher number of proposed tests (aOR 1.69 [1.01-2.86]). PITC practices and barriers differed across professions. Beyond improving environmental opportunities such as dedicated staff or services, strengthening the motivations and capabilities of healthcare professionals to propose testing could improve PITC coverage

Hibernation of mobile phones in the Netherlands:The role of brands, perceived value, and incentive structures.

Mobile phones contain valuable and rare earth minerals. At the end of their useful life, these phones are little reused or recycled since most of them are stored at home, a phenomenon also known as hibernation. Accurate hibernation rates per country or region do not exist but are assumed to be low, making end-of-life mobile phones an interesting waste stream to improve on waste recovery. This paper presents the results of a survey on the end-of-life mobile phone behavior in the Netherlands taken place in June 2019 amongst 296 participants. In so doing, it considers earlier addressed empirical concerns regarding the drivers of hibernation behavior, recycling and replacement. The hibernation rate turned out to be 61%. In line with earlier studies on mobile phone hibernation, technical and functional obsolescence are confirmed to be the main drivers of mobile phone replacement. Moreover, study results confirmed that the majority of mobile phones are replaced within three years and that using the old phone as a spare is the major reason for hibernation. This article advances several novel insights. First, the willingness to recycle appears to be inversely proportional to the perceived value of the discarded phone and proportional to the age of the mobile phone owner. Secondly, the perceived duration of ownership, a characteristic also reported in many previous studies, is incorrectly remembered by many respondents when gauging their responses against the actual mobile phone release date. Thirdly, financial incentives are shown to be the best driver to increase the intention to recycle

A service network design model for multimodal municipal solid waste transport

A modal shift from road transport towards inland water or rail transport could reduce the total Green House Gas emissions and societal impact associated with Municipal Solid Waste management. However, this shift will take place only if demonstrated to be at least cost-neutral for the decision makers. In this paper we examine the feasibility of using multimodal truck and inland water transport, instead of truck transport, for shipping separated household waste in bulk from collection centres to waste treatment facilities. We present a dynamic tactical planning model that minimises the sum of transportation costs, external environmental and societal costs. The Municipal Solid Waste Service Network Design Problem allocates Municipal Solid Waste volumes to transport modes and determines transportation frequencies over a planning horizon. This generic model is applied to a real-life case in Flanders, the northern region of Belgium. Computational results show that multimodal truck and inland water transportation can compete with truck transport by avoiding or reducing transhipments and using barge convoys
