Een slimme belastinghervorming kan een oplossing bieden voor werkloosheid, vervuiling en een te hoog verbruik van grondstoffen. Wat de Nederlandse overheid in de belastingwetgeving kan aanpassen, zodat de belastingheffing op arbeid minder is en de belastingheffing over vervuiling en grondstoffen meer is.

De gemiddelde facility manager is waarschijnlijk bekend met het feit dat een utiliteitsgebouw op meerdere aspecten wordt gewaardeerd om een energielabel te verkrijgen. Zo wordt het gebouw gewaardeerd op zowel bouwtechnische aspecten als op historisch energieverbruik.

De opbrengst van het zonnepark van Ameland heeft nauwelijks te leiden onder de ganzen die periodiek op Ameland neerstrijken. De vervuiling die zij veroorzaken is ieder jaar met name in april duidelijk zichtbaar maar zorgt amper voor een vermindering van de stroomproductie van het zonnepark. Dat hebben studenten en onderzoekers van de Hanzehogeschool Groningen vastgesteld. Mogelijke redenen hiervoor zijn het wegspoelen van de vervuiling door regen of de beperkte oppervlakte die de vervuiling inneemt.

Het loskoppelen van regenwaterafvoer van het riool is een beter middel tegen vervuiling van oppervlaktewater dan bergbezinkbakken. Dat stelt Paul van Eijk, lector Duurzame watersystemen bij hogeschool Van Hall Larenstein.

Over the past 20 years, water quality in Indonesia has deteriorated due to an increase of water pollution. Research and analysis is needed to identify pollution sources and assess contamination in Indonesian water resources. Water quality management is not yet sufficiently integrated in river basin management in Indonesia, which mainly focuses on water quantity. Women are comparatively highly impacted by failing water resources management, but theirinvolvement in decision making processes is limited. Water quality deterioration continues to increase socio-economic inequality, as it are the most poor communities who live on and along the river. The uneven water quality related disease burden in Brantas River Basin widens the socio-economic gap between societal groups. In the Brantas region, cooperation and intention between stakeholders to tackle these issues is growing, but is fragile as well due to overlapping institutional mandates, poor status of water quality monitoring networks, and limited commitment of industries to treat their waste water streams. The existing group of Indonesian change makers will be supported by this project. Three Indonesian and three Dutch organisations have teamed up to support negotiation platforms in order to deal with institutional challenges, to increase water quality monitoring capacity, to build an enabling environment facilitating sustainable industrial change, and to develop an enabling environment in support of community concerns and civil society initiatives. The project builds on integrated water quality monitoring and modelling within a framework of social learning. The strong consortium will be able to build links with civil society groups (including women, farmer and fisher unions) in close cooperation with local, regional and national Indonesian governmentinstitutions to clean the Brantas river and secure income and health for East Java’s population, in particular the most vulnerable groups.

Stormwater runoff has severe negative and direct impact on the quality of surface waters and groundwater. The impact can cause chemical and heavy-metal pollution. Applying well established methods to map pollutants in urban areas and specifically in Nature-Based Solutions (NBS), such as Sustainable UrbanDrainage Systems (SuDS) is a step towards improving the water quality in the urban water cycle. Traditional mapping of pollutants by the means of soil samples is costly, which is the main reason why the environmental-technical functioning of rainwater facilities has not been investigated on a large scale andsystematically. X-ray fluorescence (XRF) is a known analysing method for finding metals and other components, for laboratory analysis and portable instruments. In this work we propose a new approach of mapping method for pollutants in-situ, such as heavy metals in soil in SuDS, with case studies from theNetherlands where swales were implemented 20 years ago. In situ XRF measurements is a quick and costefficient analysis for heavy meatal mapping in the respect to contaminated soil. In situ XRF measures of various elements, including heavy metals is carried out in a quickscan and accurate manner and measures both qualitatively and quantitatively. It makes the time-consuming and costly interim analyses by laboratories superfluous. In this study, we suggest a new methodology approach for in situ mapping of pollutants in various swales that were implemented from 20 to 5 years ago. The results differ due to multiple factors (age, use of materials, storage volume, maintenance, run off quality, etc.). Several locations reached unacceptable levels, above the national thresholds for pollutants. The spatial distribution of pollutants in the over 30 swales mapped in the Netherlands show that the preferred water flow in theSuDS controls the spreading of pollutants. The swales investigated are presented in an interactive way with the open source tool www.climatescan.nl, containing more than 100 swales, part of which has been investigated with in situ XRF measurements. The research results are of great importance for all stakeholders in (inter)national cities that are involved in climate adaptation. SuDS is the most widely used method for storing stormwater and infiltrating in the Netherlands. However, there is still too little knowledge about the long-term functioning of the soil of these facilities.

Het imago van De Hurk in Eindhoven is ten onrechte negatief, vindt Cees-Jan Pen van Fontys. ‘Met verbazing lees ik recente berichtgeving over hinder, overlast en vervuiling van een van onze grootste werkgevers, industriepark De Hurk.’ Wat Pen betreft is De Hurk van groot belang voor Eindhoven, nu maar zeker in de toekomst.

Geen gebrek aan loftuitingen voor de circulaire economie. Méér banen, minder grondstoffen, méér groei, minder vervuiling. Maar er zijn ook schaduwzijdes. Drie inconvenient truths tonen risico’s voor de verdeling van macht en waarde in de circulaire economie. Bij dit artikel horen vijf referenties; deze vindt u op vvm.info/nu-in-tijdschrift-milieu
