A variety of products in carton packaging, from milk, until the juices, producing very large volumes of waste.
Packaging used can be processed into a multifunctional building materials.
Separate the layers.
From landfills, Tetra Pak carton packaging collected. Tetra Pak cartons consisted of 75% cardboard, aluminum and 25% polyethylene, separated on the constituent materials.
Layer of cardboard is sent to paper mills, while a layer of aluminum and polyethylene is processed. Mixture of both materials is then destroyed by machines into small pieces and then heated (200-2550 degrees Celsius) and pressed into a sheet panel.
No need for glue to bring together the pieces. This is because the protection of polyethylene (PE) is a type of plastic will melt and become adhesive. It also makes a panel called polyboard and polyroof be strong and supple.
Indeed, aluminum and polyethylene layers on the packaging does not decompose. Precisely because of that, how this material can be fully utilized by other functions, namely as building materials. When the production process, as for the rest of the pieces that can be blended back into a new sheet panels.
Installation is easy.
The panel that produced the company in Indonesia is made up of 2 models. The first is polyboard, a 6-14 mm thick flat panels, which can serve as wall panels, partitions, or ceilings.
The second is called polyroof, a corrugated sheet that serves as a roof. There are two types of waves, big and small. Than asbestos sheets, polyroof has a lighter weight. The comparison, of the same size, asbestos sheets weighing 11 kg, while polyroof only 5-6 kg.
Panels are in pairs by way of screwed or nailed to a wooden or metal frame, just like the installation of asbestos or gypsum. Because the material is flexible, as he nailed not susceptible to rupture. Even this panel can be connected by cement, among others, in relation roof (not edges). If necessary cut, simply use a chainsaw.
The display of polyroof and polyboard panel is colored gray with tiny granules of silvery aluminum layer of epidermis are destroyed. If you want different colors, these panels can be painted. For maximum results, use oil paints.
Changing perceptions.
As a roofing material, the panel recycled cardboard packaging is ideal to use in the tropics. The content of aluminum in it can reflect the heat so as to reduce the heat of 20-40%. In addition, this material can also muffle the sound, so the sound of rain that falls I roof can be reduced.
In a region prone to earthquakes, lightweight material is advantageous because the risk of injury can be reduced. In eastern Belitung (Indonesia) has built homes of fishermen polyboard material. During a fire, non-flammable material that makes the occupants had escaped.
But there are still a tough task to be performed, namely changing the public perception of the material from recycled waste. According to the study, in Brazil was 30-year project from waste-packaging material were developed.
