This paper investigates interactions between exporting and productivity at the firm level, using a panel of firms in the UK chemical industry. This is both highly technology intensive and the UK’s largest exporting sector. We find exporters are more productive than non-exporters, but are also on average smaller. This superior productivity performance among exporters appears to be caused by both...
The chemical industry has an enormous need for innovation. To save resources, energy and time, currently more and more established chemical processes are being switched to biotechnological routes. This requires white biotechnology to discover and develop novel enzymes, biocatalysts and applications. Due to a limitation in the cultivability of microbes living in certain habitats, technologies ha...
Biocatalysis has proven to be a useful supplementary technology for the chemical industry, allowing in some cases reactions which are not easily conducted by classical organic chemistry or in other cases allowing reactions which can replace several chemical steps. Highly chemo-, regioand stereoselective bioconversions can simplify manufacturing processes to make them even more economically attr...
