In Europe, each citizen generates an average of 1.78 tons of construction waste per year, being this industry responsible for one third of all global waste. And the main reason are the materials used, most of them not recyclable. This is why at Honext we have developed and patented a process, product and application, which transforms the primary sludge generated by the paper industry into a new cellulose-based material, sustainable, versatile, with excellent properties (reaction to fire, moisture, acoustics, mechanical resistance, non-toxic) to be used as interior partitions in construction. The material is recyclable and we obtained the Cradle-to-Cradle silver certificate.

We have finished the implementation of the first production factory, located in a Waste Treatment Center in Vacarisses (Barcelona), and we are now ready to commercialize the product. It has an annual production capacity of 2,000 m3 of panels. The manufacturing process, in addition to using the sludge from paper mills as raw material, incorporates water coming from the landfill leachate, as well as methane and electricity generated from waste.
