Most colors are eco criminals: Here’s how to make purple greener

Goodbye to crude oil-based dyes: Biotech start-up and scientists revolutionize paint production


The colors of our clothes, cosmetics, furniture and all sorts of things around us are nearly all based on crude oil, making them far from environmentally innocent. University of Copenhagen researchers have teamed up with Danish biotech start-up Octarine Bio to create new types of sustainable ...

Chemists to capture atmospheric methane with sugar

Can a carbohydrate actually suck methane, a greenhouse gas, directly out of the air?


Researchers at the University of Copenhagen’s Faculty of Science are in the process of finding out. Methane gas is 86 times more potent than CO2 and one of the major contributors to global warming. It is estimated that methane accounts for 30 percent of all global warming from gaseous emissions. ...

Designing protection suits for hard working bacteria

A new technique makes bacteria cells more robust and efficient for various chemicals synthesis under harsh application conditions


Every day, chemical factories produce a wide range of products that will be extremely difficult to do without in a modern society; everything from medicines like insulin and antibiotics to fertilizers. The basis of such products often consists of bacteria, which can produce chemicals and drugs in ...

Breakthrough in separating plastic waste

Machines can distinguish 12 different types of plastic thereby separate plastics according to their chemical composition


In contrast to common perceptions, plastic is in no way near one material. Rather, it is a combination of many materials (polymers) with different chemical compounds and additives such as pigments or fibres, depending on its use. It is very difficult to tell the difference between different types ...

New method for producing synthetic DNA

Chemically synthesized short DNA sequences are extremely important ingredients with countless uses


The DNA sequences produced are also called oligonucleotides. These are widely used for disease identification, for the manufacture of oligonucleotide-based drugs, and for several other medical and biotechnological applications. The high demand for oligonucleotides therefore requires an efficient ...
