In the case of recycling, we often include the numbers of the recycled materials. Number 1 is soda and water bottles, number 2 is laundry detergent and other containers, and number 4 is plastic bags. There is also foam # 6, which consists of packaging materials for electronics and furniture, trays and containers for food, foam cups, egg cartons, peanuts, and medical coolers, all made of polystyrene. This type of foam is also commonly called polystyrene, polystyrene or EPS foam.
Polystyrene is one of the most common forms of plastic. The material is a mixture of approximately 98% air and only 2% polystyrene; it is resistant to water and heat, making it an excellent insulator. Due to its popularity, the global demand for EPS and its production is increasing, and hence the demand for recycling methods.
While foam peanuts can be recycled by reusing them, all other EPS materials must undergo a recycling process that reduces their volume. To recycle it, the material must be checked and all other contaminants removed. The foam is then fed to recycling machines for cold or thermal thickening. The foam can be compacted to reduce the volume with a compactor, without the use of heat. The result is dense logs or bricks that achieve a volume reduction of 98%. In the case of the thermal method, the foam is fed to the compacting machine. The thickener uses heat and friction to melt the foam. The machine then uses pressure to force the material into a small hole and then extrude it into long, narrow strands. As soon as the recycled foam has cooled, it is cut into granules that facilitate transportation. The recycled foam is then shipped to other manufacturers to create new plastic products.
Number 6 Recycled Foam is a great resource for creating new, cost-effective materials and products. For example, it can be used to create photo frames, pens and office supplies, clothes hangers, curtain poles, garden furniture, CD boxes, toys and pony packaging for growing and transporting seeds and plants. It is used to create interior and exterior architectural moldings, decorative interior decorations and SIPS (Structural Insulated Panels). Recycling EPS can also be mixed with wood or concrete to serve as an excellent building insulation agent as it is resistant to water, mold and rot, or can be used to produce additional foam packaging material.
There are many advantages to using recyclable foam instead of the original raw material to create new products. It saves natural resources, reduces littering and pollution, saves space in landfills and uses less energy. Recycled foam has real value for new product manufacturers looking to pay well for their recycled material. Recycling of foam has become much easier and more efficient in recent years due to technological advances; Recycling equipment now reduces foam volume by up to 95% from its original size and requires significantly less work than in the past. Recycling essentially reduces the amount of landfill and creates a more sustainable, green environment for all of us.
