Outdoor textiles must be practical and functional: they should protect equally well against rain, wind and dirt. To meet these high demands, the textile industry has so far used so-called hydrophobing agents for impregnation. However, these usually consist of petroleum-based fluorine compounds, which have been proven to harm the environment and people. Rudolf GmbH, a company specializing in textile chemicals, now wants to launch a fluorine-free alternative made from renewable raw materials.

“Environmental policy is part of agriculture.” This was a clear message by Christian Schmidt, the Federal Minister of Agriculture, at the recent  “Dialogue for the future: Agriculture and Food”. Thus far this sector is under a lot of pressure due to its high CO₂ Emissions. The demands for more sustainability in terms of farming and animal husbandry have been at the top of the political agenda for some time now. However, there are already a number of farms that fully embrace a resource-saving and environmentally conscious production.

Fossil resources are becoming scarce and their use is a burden on the environment. Therefore new technologies to replace these resources are needed. Part of the replacement can be achieved by employing electrical power production based on renewable resources, such as wind and solar energy. Additionally, renewable feedstocks and waste streams have to be considered as valuable precursors for the production of commodities and fuels.

Last May Clariant announced a merger with the US company Huntsman regarding biobased chemicals. And now there are again news out of the headquarters: the Swiss chemical company licensed their Sunliquid-Technology for the conversion of biowaste into ethanol to the Slovakian bioethanol specialist Enviral.

The specialty chemicals company Evonik opened a new production site for its Evonik Advanced Botanicals subsidiary in Tours, France. Evonik is active in over 100 countries and the subsidiary was originally founded in 2016, when Evonik acquired the French startup Alkion Biopharma SAS, an expert in biotechnological production of plant-based active ingredients.

Many animals provide ingenious inspirations for new materials and their production. Spiders, for instance, produce silk that withstands enormous forces and which has since been artificially generated in a laboratory setting. Similarly, mussels secrete byssus threads that can attach strongly to any material underwater – a long sought-after property. Velvet worms, small animals somewhere between an earthworm and a caterpillar, are equipped with an equally unique material: a sticky liquid that wards off enemies or catches prey.

Mosses are the second largest group of land plants today, and arguably the oldest. For millions of years, these plants have been producing highly complex molecules out of simple chemical building blocks, in a sustainable, efficient and cheap manner. Many of these chemical substances are used in medicine and the perfume industry today.

Air pollution is most commonly associated with traffic and car emissions. However, there are a number of other sources for pollution, such as agricultural emissions due to fertiliser use. According to researchers at the Max Planck Institute for Chemistry in Mainz, Germany, reducing ammonia (NH₃) emissions by 50% could avoid the deaths of more than 250,000 people each year that are caused by air pollution worldwide.
