Microbial electrosynthesis (MES) is an electricity-driven production of chemicals from low-value waste using microorganisms as biocatalysts. MES from CO2 comprises conversion of CO2 to multi-carbon compounds employing microbes at the cathode which use electricity as an energy source. This thesis presents innovations on MES from CO2 using anaerobic ...
Interest in sustainable development together with limited amounts of fossil resources have increased the demand for production of chemicals and fuels from renewable resources. The market potential for bio-based products is growing and a transition from petrochemicals to biomass-based chemicals is ongoing. Itaconic acid is a C5-dicarboxylic acid whi...
De lijst van zeer zorgwekkende stoffen is lang. Onderzoeker Daan van Es van de Wageningen UR liep de lijst door en ziet goede kansen voor biobased vervangers.
Exposure models are used to calculate the amount of potential harmful chemicals ingested by a human population. Examples of harmful chemicals are residues of pesticides, chemicals entering food from the environment (such as dioxins, cadmium, lead, mercury), and chemicals that are generated via heating (such as acrylamide and furans). In this report...
While providing an option for development in coastal areas, shrimp farming is usually associated with high environmental cost due to the loss of mangrove forest and high social cost as farmers suffer heavy financial losses due to disease outbreaks. Planning shrimp farming requires to integrate risk as well as social and environmental cost. This the...
A quick scan of the ZZS (zeer zorgwekkende stoffen) list of 371 substances of very high concern shows that there is significant potential in biobased replacement of part of the list. It is shown that in many cases easily implementable biobased alternatives are already available or in advanced stages of development. However, in some cases safe, biob...
Rijkswaterstaat van het Ministerie van Infrastructuur en Milieu is in 1992 gestart met de uitvoering van het monitoringprogramma “Monitoring Zoete Rijkswateren”. Dit vormt een onderdeel van de “Monitoring van de Waterstaatkundige Toestand des Lands” (MWTL). Doelstellingen van de metingen zijn: - het signaleren van langjarige ontwikkelingen in de bi...
The diet of children aged 2 to 6 years in the Netherlands is safe regarding the exposure to fumonisin B1, deoxynivalenol, patulin (toxic compounds produced by fungi), nitrate and organophosphorus pesticides. For dioxins, that are mainly present in animal fats, there is a limited probability that an adverse health effect will occur. For acrylamide, ...
Het RIVM en het RIKILT-Instituut voor Voedselveiligheid schatten hoeveel chemische stoffen mensen via voeding binnenkrijgen. De huidige methode zou meer inzicht moeten kunnen geven in de mate waarin deze blootstellingsschattingen onzekerheden bevatten. Het kwantificeren van onzekerheden sluit aan bij de internationale wetenschappelijke activiteiten...
