Kärcher turns to Technyl® 4earth® on the path to a sustainable future

As more and more companies recognize the benefits of recycling and re-use of materials, demand for recycled plastics for commercial applications is growing. Whether spurred by regulation or the market, manufacturers in the building and construction, automotive and electronics sectors, in particular, are turning to recycled polyamide for use in their sustainable product designs.

Kärcher, the leading manufacturer of cleaning technology, is one such company that is strongly committed to increasing its use of recycled materials in its pressure-washer and other products. This is why the company was one of the first major international OEMs to evaluate and embrace Solvay’s Technyl® 4earth® premium recycled polyamide technology.

Sustainability and environmental protection are firmly rooted in our company philosophy and actions,” says Daniel Carmine MANOCCHIO, Manager of the group Material Technology at Kärcher’s Central Research and Development. “After adopting Technyl® 4earth® as a component of our resource-conserving solutions, we have already manufactured more than 1 million high-pressure spray lances molded using this remarkable recycled polyamide.


A sustainable alternative

The spray lances must meet a range of demanding requirements, including high pressure resistance, hydrolytic stability, very high impact strength, printability and compatibility with cleaning agents. After comprehensive testing, Kärcher selected a 30% glass fiber reinforced Technyl® 4earth® compound precisely because it meets these criteria.

It behaves exactly as comparable virgin PA6.6 both in terms of physical in-use properties and processability, without compromising the superior quality and safety of our equipment,” MANOCCHIO adds. “After switching the first production plant completely from virgin Technyl® to Technyl® 4earth® we are now evaluating its further use throughout our extensive portfolio.

We are proud to have such a globally renowned brand manufacturer as Kärcher recognizing the value of Technyl® 4earth®,” says Richard BOURDON, Move4earth® Project Director for Solvay. “The spray lance is a perfect example of the demanding applications we are targeting while exploring new opportunities and partnerships with customers seeking to foster sustainable design and increase the recycled plastic content in their products.


Consider the environment

Technyl® 4earth® is a range of PA6.6 engineering plastics born out of the Move4earth® project supported by the European Commission (LIFE+ program). A patented process transforms stable sources of technical fabrics, such as automotive airbag cushions, into prime quality polyamide. Technyl® 4earth® offers properties comparable to those of equivalent virgin PA6.6 and can significantly reduce the environmental impact in terms of CO2 emissions, water consumption, and use of non-renewable energy.

Technyl® 4earth® is commercially available in various grades with up to 50% glass content. Solvay’s proprietary recycling technology ensures both consistent material quality and security of supply to meet fast-growing demand for more sustainable high-performance applications in a wide range of markets, from automotive components to electrical appliances, and consumer and industrial goods.
