To ensure a circular economy for plastics, insights in the environmental impacts of recycling and optimal recycling choices for specific plastic polymers are crucial. This was obtained by determining the environmental performance of 10 selected recycling technologies with varying TRL levels, using the chemical properties of the top 25 produced...

Tropospheric ozone is a secondary pollutant which can affect human health and plant growth. In this paper, we investigated transferred convolutional neural network long short-term memory (TL-CNN-LSTM) model to predict ozone concentration. Hourly CNN-LSTM model is used to extract features and predict ozone for next hour, which is superior to...

The unprecedented order, in modern peaceful times, for a near-total lockdown of the Greek population as a means of protection against severe acute respiratory syndrome coronavirus 2, commonly known as COVID-19, has generated unintentional positive side-effects with respect to the country’s air quality levels. Sentinel-5 Precursor/Tropospheric...

We quantify the reductions in primary emissions due to the COVID-19 lockdowns in Europe. Our estimates are provided in the form of a dataset of reduction factors varying per country and day that will allow the modelling and identification of the associated impacts upon air quality. The country- and daily-resolved reduction factors are provided...

The second Cabauw Intercomparison of Nitrogen Dioxide measuring Instruments (CINDI-2) took place in Cabauw (the Netherlands) in September 2016 with the aim of assessing the consistency of multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements of tropospheric species (NO2, HCHO, O3, HONO, CHOCHO and O4). This was achieved...

The effect of potential policy measures to reduce the emissions of NOx and NH3 in several sectors has been analyzed and reported in this document for the Dutch government. In this background report of TNO the effect of four policy measures has been described, which all focus on the industrial sectors and energy sectors, such as electricity...

Elemental Carbon (EC) is a good indicator for aerosol air quality and a main component in global warming; therefore data on its historic concentration would be highly valuable for an assessment of historic levels. There were already major sources of EC in Europe in the early 20th century, but the component has only been measured since the late...

Particulate matter (PM) remains as one of the most relevant air-quality concerns in urban environments. The Berlin agglomeration area is still affected by exceedances of the daily limit value of the PM concentration, especially during wintertime PM episodes. In this study, we present test-case studies with the LOTOS-EUROS CTM to improve the...

This study aims at estimating errors to be accounted for in atmospheric inversions of methane (CH4) emissions at the European scale. Four types of errors are estimated in the concentration space over the model domain and at selected measurement sites. Furthermore, errors in emission inventories are estimated at country and source sector scales....

De Green Deal Duurzaam GWW 2.0 (GD DGWW 2.0) is gestart in 2017 en heeft als ambitie om “duurzaamheid in 2020 een integraal onderdeel te laten zijn van spoor-, grond-, water- en wegenbouwprojecten”. Nu de green deal ten einde loopt, rijst de vraag welke resultaten er tijdens deze looptijd zijn bereikt. De hoofdvraag van deze kwantitatieve...

Samenvatting Om naderinzicht te krijgen in de besmettingsrisico’s met SARS-CoV-2 in binnenruimten en welke factoren hierin een rol spelen, is er behoefte aan berekeningsmodellen waarmee we dit kunnen inschatten. De berekening van de kans op een individuele besmetting met Sars-CoV-2 via de aerogene route wordt momenteel vaak bepaald met het...

We present a modelling framework for fossil fuel CO2 emissions in an urban environment, which allows constraints from emission inventories to be combined with atmospheric observations of CO2 and its co-emitted species CO, NOx , and SO2. Rather than a static assignment of average emission rates to each unit area of the urban domain, the fossil...

Natural sea-salt aerosols, when interacting with anthropogenic emissions, can enhance the formation of particulate nitrate. This enhancement has been suggested to increase the direct radiative forcing of nitrate, called the "massenhancement effect". Through a size-resolved dynamic mass transfer modeling approach, we show that interactions with...
