The World Bank (2016) has estimated the air pollution co-benefit estimate for the EU, for each tonne of greenhouse gas emissions reduced, at an additional $200. Deng et al. (2017) noted that while the co-benefits of mitigating GHG can serve as an input to CBA, perhaps more importantly...
The present methane emissions in the Netherlands amount to 1190 ktonne per year. It is expected that these emissions will decrease by 20% up to the year 2000 due to environmental policies already in place. However, additional emission reduction may be necessary. In this article, the reduction ...
Using #4 rebar this equates to 14.1 kg of zinc for every tonne of rebar. The hot dip galvanization process obtained from the industry average of the American Galvanizers Association (AGA) was used as a proxy for the continuous galvanizing process, modified to account for the difference...

It was also stated that an average 2.4 % of the total population experienced the fracture per year and while distinguishing between genders, it was found that men carried a slightly greater percentage (2.8 %) than women (2.0 %) [1]. For bone fracture treatment, some European surgeons have ...
Compared to the virgin crushed stone and sand sub-base and unbound-base courses; virgin HMA base, binder and wearing courses; and 100% ordinary Portland cement (OPC) used in “AR1”; recycled materials were used in “AR2”. The material requirements and performance parameters of the “AR1...
The sand used for the moulds can be regenerated by thermal processing and can be valorised this way several times before it is discarded [13], reducing the amount of waste generated per cycle. The surfaces of the mould cavity have to be lubricated in order to facilitate removal of the ...
