3 ways to fight climate change

May 4, 2016

There are as many ways to combat climate change as there are people on the planet. We can all find our own way to make a difference. These are the five steps Walki recommends. We hope they inspire you as well.




The use of synthetic materials affects the environment in many ways. In reality, materials made from fossil fuels – such as plastic – are easily replacable.


The basis of 4E Antenna products is a renawable and recyclable fiber-based material. Many are unaware of how advanced lamination techniques can turn paper, cardboard and fiberboards into moisture, grease, UVA and freeze-resistant packaging.


Billions of RFID tags are based on plastic substrates. All of them could easily be replaced with our paper-based 4E Antenna product.




Many of us associate the word ’recycling’ with collecting and sorting old, used packaging. Reusing old materials is just as important.


So far, recycled materials containing ink have been dangerous to reuse as the remnants of chemicals can absorb into food and then the body.


Luckily, 4E Antenna has a solution to offer. 4E Antenna uses paper as a base material för the antennas. The technology offers a well-researched, safe way to reuse materials and avoids hazardous, environmental dangerous, materials.




Digitalisation is a breakthrough that will increase efficiency, productivity and reduce environmental impact. The most interesting technologies revolve around the IoT, Internet of Things.


With the IoT, countless things and objects will be personalised, recognised and controlled digitally with RD

IF antennas. The antennas provide a link between the reader and product, packaging and tags. This is where Walki enters the picture.


4E Antenna has developed a new, patented and award-winning technology for flexible circuit boards. The laser technology is far more eco-friendly than the traditional etching. Yet it is just as efficient. In fact, 4E Antenna is the most advanced option: more precise, 10 times quicker in production, cheaper and recyclable, it’s compatible with nearly every material.
