Introduction

Today we burn around 80% of all the waste that is collected directly at homes. By recycling more, we can prolong the useful life of many of the materials that otherwise would be wasted.

Plastic currently comprises 12% of the total waste collected from Danish homes, and with approx. 2.5 million tons of household waste, a lot of valuable resources are being incinerated.

At Lendager Group we have developed and designed acoustic ceiling panels from PET-plastic in the shape of PET-felt. We wanted to use PET-felt as an acoustic element, because of its acoustic properties, aesthetic potential and the obvious reduction of plastic waste in the environment.

For every kilogram of plastic reused, the environment is spared 1.5 kilograms CO2. This is why it makes such good sense to reuse and recycle plastic.

Upcycling

Huge amounts of PET bottles are collected, washed, colour sorted and subsequently granulated, heated and extruded to raw PET fibres. A mashine puts layer after layer of PET fibres in the same direction and felts the individual fibres together to form larger felt areas. The very thin PET felt latyers are then pressed onto each other in thicker layers to create a stable and robust sheet of PET felt, ready for subsequent processing.

PET felt is an environmentally friendly material since it consists of 100% recycled bottles. PET felt has a very soft, felt texture with a slightly rough surface.

Design

For the project Copenhagen Towers in Ørestad, Copenhagen, Lendager Group were asked to raise the sustainability profile of the project by covering the interior surfaces with upcycled materials. Not only should the materials be sustainable, they should also fit seamlessly into a high-end, exclusive office setting.

The background for the development of the acoustic panels and their design was the assignment to create a suspended ceiling made of recyclable materials. It should act as acoustic regulation, have aesthetic qualities and be visibly as well as measurably sustainable.

The specially developed acoustic ceiling panels consist of a back plate onto which PET felt is mounted in an optimized geometry with high acoustic performance. In section the panels display a compressed sine-wave shape.

The PET felt that we use for the acoustic panels has both sound dampening and sound absorbing properties. The felt can be used for acoustic regulation in office settings, institutions as well as in homes. The felt in itself has strong aesthetic and tactile qualities, and our supplier works to ‘cradle-to-cradle” standards.
