Light pollution is one of the fastest growing and most pervasive of environmental pollution (Chepesiuk, 2009). In the last couple of years, a lot of research has been done about the effects of light pollution. The interest in light pollution has been growing in many fields of science, extending from the traditional field of astronomy to atmospheric physics, environmental sciences, natural sciences and human sciences. Better insight in light pollution is likely to contribute to design and operation of Facility Management (FM) based on evidence. According to Cinzano, Falchi, & Elvidge (2001), the Netherlands is one of the countries with the highest amount of light pollution, just as the United States. A sample of students in the Netherlands and the United States has been taken to explore differences and similarities between the two countries.

Two key air pollutants that affect asthma are ozone and particle pollution. Studies show a direct relationship between the number of deaths and hospitalizations for asthma and increases of particulate matter in the air, including dust, soot, fly ash, diesel exhaust particles, smoke, and sulfate aerosols. Cars are found to be a primary contributor to this problem. However, patient awareness of the link is limited. This chapter begins with a general discussion of vehicular dependency or ‘car culture’, and then focuses on the discussion of the effects of air pollution on asthma in the Netherlands. I argue that international organizations and patient organizations have not tended to put pressure on air-control, pollution-control or environmental standards agencies, or the actual polluters. While changes in air quality and the release of greenhouse gases are tied to practices like the massive corporate support for the ongoing use of motor vehicles and the increased prominence of ‘car culture’ globally, patient organizations seem more focused on treating the symptoms rather than addressing the ultimate causes of the disease. Consequently, I argue that to fully address the issue of asthma the international health organizations as well as national health ministries, patient organizations, and the general public must recognize the direct link between vehicular dependency and asthma. The chapter concludes with a recommendation for raising environmental health awareness by explicitly linking the vehicular dependency to the state of poor respiratory health. Strategic policy in the Netherlands then should explicitly link the present pattern of auto mobility to public health. https://onlinelibrary.wiley.com/doi/book/10.1002/9781118786949 LinkedIn: https://www.linkedin.com/in/helenkopnina/

Metropolitan Cebu, the third largest agglomeration in the Philippines with a population of approximately 3 million, faces significant challenges in managing domestic wastewater and solid waste. This mismanagement has led to the pollution of its water bodies, including the Mahiga Creek and the Butuanon River, the latter of which was declared dead in 1992 and can no longer support flora and fauna. Between 2017 and 2025, seven international River Challenge Climate Cafes were conducted by Dutch universities of Applied Sciences and Filipino universities . During these events, teams of young professionals assessed the upstream, midstream, and downstream stretches of Metro Cebu's rivers and evaluated the vulnerability of 12 urban poor communities living along these rivers. The primary aim of these rapid appraisals was to raise awareness among community members, local governments, and students, as well as to build capacity. Throughout the process, there was a shift from merely gathering data on pollution levels to engaging the community, identifying risks, and finding feasible solutions to mitigate these risks. Various methods were employed to measure water quality, river width, river discharge, flood heights, ecology, plastic waste pollution, and residents' perceptions. The results were shared online via Climatescan.org with the global climate adaptation community. The findings demonstrate that river challenges are effective tools for creating context-rich learning environments for students, with more than 250 participants. The River Challenge Climate Cafe enable young professionals, primarily with technical backgrounds, to gain firsthand field experience, exposure to environmental degradation, severe pollution, and vulnerable communities, thereby enhancing their environmental awareness. Additionally, the river scan challenge proves to be a valuable tool for increasing awareness of river pollution and promoting rehabilitation effortsHow to cite: Heikoop, R., Boogaard, F., Abrenica, B., Fornis, R., Borgonia, K., Ledesma, D., Nasara, J., Boer, E., and Oudendammer, T.: Enhancing Environmental Awareness Through River Challenges: A Case Study of Metropolitan Cebu, Philippines , 12th International Conference on Urban Climate, Rotterdam, The Netherlands, 7–11 Jul 2025, ICUC12-1052, https://doi.org/10.5194/icuc12-1052, 2025.

The objective of Waterrecreatie Nederland is to improve water recreation in the Netherlands. One of the focus points that the foundation focuses on is strengthening sustainable water recreation. With this study, Waterrecreatie Nederland wants to map the current CO2 emissions of recreational shipping (here: sailing and motor boats), in order to be able to report and communicate about this, and also as a baseline measurement for future monitoring in this area.Societal IssueShipping has a substantial impact on several environmental systems, amongst others through air and water pollution, and its contribution to climate change. The role of recreational shipping in these issues is not well known, as measurements are scarce and often partly based on assumptions. Benifit to societyThis project tries to strengthen the knowledge base on the carbon (CO2) emissions of recreational shipping in the Netherlands, and to provide detail on fuel use, fuel types, distances, etc. That knowledge can help in making more informed choices on the future development of recreational shipping, with a lower impact on climate change.
Fungal colorants offer a sustainable alternative to synthetic colors, which are derived from fossil fuels and contribute to environmental pollution. While fungal colorants could be effectively produced through precision fermentation by microorganisms, their adoption in industry remains limited due to challenges in processing, formulation, and application. ColorFun aims to bridge the gap between laboratory research, artisanal practices, and industrial needs by developing a scalable and adaptable colorant processing system. Building on the TUFUCOL project, which focused on optimizing fungal fermentation, ColorFun consortium gears the focus to downstream processing and industrial applications by using green chemistry. Many SMEs have explored fungal colorants using traditional methods, but due to lack of consistency and reproducibility, they are unsuitable for large-scale production. Meanwhile, lab research usually does not translate directly to industrial applications. Researchers can fine-tune processes under controlled conditions while large-scale production requires consistent formulations that work across different material substrates and processing environments. Without bridging these gaps, fungal colorants remain confined to research and small-scale applications rather than becoming viable industrial alternatives. Instead of developing separate solutions for each sector, ColorFun is working towards a set of standardized extraction and stabilization methods for a stable base colorant product. This pre-processed colorant can then be adjusted by different industries to meet their specific needs. This approach ensures both efficiency in production and flexibility in application. Professionals will collaborate in a test-improve-test circle, ColorFun will refine these formulations to ensure they work in real-world conditions. Students will be involved in the project, contributing to curriculum developments in biotechnology, chemistry, and materials science. Combining efforts, ColorFun lowers the barriers aiding fungal colorants to become a mainstream alternative to synthetic feedstocks. By making these colorants scientifically validated, industrially viable, and commercially adaptable, the project helps accelerate the transition to sustainable color solutions and circular economy.
In Europe we consume 50 million tonnes of plastic a year. The use of plastic has increased fiftyfold in fifty years and the growth continues. Collecting and recycling plastic is thus essential to avoid the pollution of the land and sea. However, generally, post-consumer plastics have very low recycling rates, at present only 7% of plastic used in Europe comes from recycled polymers. Polyethylene terephthalate (PET) is one of the most recycled materials; in 2017 more than 57% of PET bottles were recycled in Europe, used in both packaging and fibre applications. Especially transparent PET bottles have high collecting and recycling rates over Europe. However, the plastics have very different value depending on their colour. If the plastic is even very lightly coloured, the plastic will lose a large percentage of its value. Decolouring plastic is complicated and currently no efficient and economically viable system exists. FT Innovations, a SME with the core-expertise in extraction, sees potential in developing a sustainable decolouration process with a new extraction technology, which offers significant potential in replacing hazardous, relatively expensive and environmentally damaging organic solvents that are currently used on decolouration. Avans has relevant expertise in both (biobased) plastic colourants and the extraction techniques as demonstrated in previous projects, and therefore FT innovations approached Avans with the request to assist in the feasibility study. The consortium is further strengthen by CCT Oss with their strong industrial know-how of colourants and their use in plastics and Plastic Company with their core activity on recycling of PET and other plastic materials.
