What are Critical Raw Materials?
CRMs are materials which are significantly important for companies in order to manufacture their products but have a high-risk associated with their supplier. This high-risk is that the materials are very rare and unique and there is a lack of substitutes for them. Nowadays the supply of these raw materials is increasingly coming under pressure. In order to control this problem, the EU commission has created a list of CRMs and is monitoring the CRM market at all times. Here are some examples: More...
We focused on Transportation all over the world including planes, cars and lorrys. Transportation, not only goods but also people transportation, causes 30 % of the whole CO2-emission. We made some research about what could be a usable and simple solution to reduce the amount of the worldwide emission. Have you ever asked yourself what causes the most CO2-emission?

Urban mining
Eco-friendlier with urban mining (Audio)
Urban mining is a revolutionary way of environmental recycling. In urban mining a city is seen as a place to regain raw materials. It is different from the recycling process we usually know (such as for glass or PET), because it is the recycling of different valuable substances from a mix of materials. It involves methods which are alike to those used by the extraction of resources from rocks, which is why it’s called “mining”. When a house is abandoned, both objects like a wooden door and raw materials like iron can be saved from the ruin. More...
First of all, what is plastic? It is a durable material that takes up to 450 decompose. It is estimated that 3-10% of the 300 million tonnes produced every year end up directly in the oceans.
How can you reduce using plastic? Try not to use plastic bags. Require a bag made of fabric instead. And in place of plastic bottles buy a bottle, which is a little expensive but one that you can use for a long time. Say no to plastic utensils and avoid microbeads. More...

What is electronic waste?
Electronic waste are used electronics which are destined for refurbishment, reuse, resale and recycling.
Norway and other european countrys lead the world electronic waste production. In 2017, each inhabitant in Norway produced 28.5 kg of electronic waste.
However, electronic devices can be recycled. They are often shredded and sorted. After they are separated into clean commodities that can be used to make new products.
The problem is, not every electronic device can be recycled easily. For example ovens or cooling equipments such as freezers, are often full of toxic chemicals such as lead and ozone destroying substances.
Sadly, electronic waste does often get mixed up with general household waste. If it ends up in general waste, it can not be recycled. This is why an efficient separation of waste is very important!

The breakdown of sulfur is a very challenging and hard work. It is extracted out of highly toxic gases in acid lakes or out of volcano mines. The workers have a big lack of equipment and their life expectancy is at 50 years, coughing blood is normal for them.
The mineworkers who breakdown sulfur on the Java island in Indonesia are working on the most difficult and dangerous conditions. But what are their lives worth and what is sulfur used for?
