Safe water in conflict zones is extremely important
by Kees Roest PhD BSc

UNICEF published a report on water supply for children in complex humanitarian emergencies, drawing on data from 16 conflict-affected countries. The UN agency notes that almost three times as many children under 15 worldwide die from diarrhoeal diseases caused by lack of water, sanitation and hygiene (WASH) facilities than from actual conflicts; for children and infants under five, more than…...

Sewage reveals levels of antimicrobial resistance worldwide
by Kees Roest PhD BSc

Sewage can reveal the occurrence of antimicrobial resistant bacteriain in the, mainly healthy, population. Antimicrobial resistance is mainly related to the sanitary conditions in the country and the population’s general state of health and less to the use of antimicrobials. The Netherlands, New Zealand and Sweden have the lowest levels of antimicrobial resistance, whereas Tanzania, Vietnam and Nigeria have the…...

Global Green Economy Index 2018
Global Green Economy Index 2018
by Kees Roest PhD BSc

The results from the new 2018 Global Green Economy Index™ (GGEI) are online. This 6th edition covers 130 countries (up from 80 in the 2016 edition). Like in past years, the GGEI is an integrated measurement of how each country performs around climate change, sector decarbonization, green market development and the environment. The GGEI was the first green economy index,...

Drought 2018: maize crop benefits from treated wastewater
Drought 2018: maize crop benefits from treated wastewater
by Ruud Bartholomeus PhD MSc

The 2018 drought affected agriculture heavily, especially in the sandy Eastern part of the Netherlands where freshwater supply by rivers is not possible. Treated wastewater is increasingly being considered as freshwater source for irrigation. Our experimental site in Haaksbergen clearly showed the benefits for crop yields of subsurface irrigation using treated wastewater. Additionally, the drought provides insight in the ‘worst...

Recycling for cobalt & lithium is imprtant for climate change
by Kees Roest PhD BSc

Renewable technologies (such as electric vehicles, solar panels and wind turbines) cause increased demand for cobalt and lithium. However, global supplies of both minerals are not projected to meet demand, with research forecasting shortfalls in the coming decade. Recycling of cobalt and lithium is essential to heading off predicted metal shortfalls, empowering clean energy transitions and reducing risk of human…...

Ion-exchange membranes for (waste)water treatment
by Kees Roest PhD BSc

Functional membranes based on covalent incorporation of a functionalized monomer facilitate selective electro-driven transport of phosphate or citrate from model dairy wastewater. The presented approach has the potential to prepare ion-exchange membranes that address other ions that are environmentally relevant. In this way selective membrane transport of ions can be controlled....
