Recycling EPP (expanded polypropylene) foam produced by the automotive industry can be achieved through physical methods, involving EPP recycling machines such as EPP compactors. EPP foam recycling requires the establishment of a dedicated collection and sorting system to ensure that EPP foam is separated from other waste materials, which may involve dedicated collection points at automobile manufacturers or cooperation with waste management companies.
The specific steps of EPP foam recycling are as follows:
Collection: Collect used EPP foam from automobile production plants, repair workshops or scrap vehicle processing sites.
Sorting and cleaning: Sort the collected EPP foam to remove impurities and non-EPP materials. And remove contaminants such as tapes and stickers on the EPP foam, which is conducive to the purity of the recycled materials in the EPP foam recycling process.
Crushing and compaction: The EPP compactor will first crush the EPP foam into uniform fragments and compact them into compact foam blocks. This can increase the efficiency of subsequent transportation and storage space management by 50 times.
Regranulation: The EPP granulator remelts the EPP granules into a reshapeable state through high temperature, extrude them into long and thin strips, and cuts them into tiny EPP granules for the production of new EPP products, forming an EPP foam recycling closed loop.
EPP is a completely recyclable foam that can be reused through recycling. In the EPE foam recycling process, the EPP compactor is mainly a device for reducing the volume of the foam. The GREENMAX EPP compactor can compact the foam into compact blocks at a ratio of 50:1. At the same time, in order to prevent the foam from expanding from the inside, the EPP recycling machine adds surface hot melt technology to melt the surface of the EPP blocks and solidify quickly.
The EPP compactor mainly uses physical extrusion technology, so it will not change the properties of the EPP foam blocks, which is convenient for the subsequent reuse of recycled materials. Compacting the EPP material makes the material easier to handle and manage, speeds up the material flow in the production process, and reduces the unit transportation cost. EPP foam recycling helps to effectively recycle and reprocess waste EPP, in line with the requirements of environmental protection and sustainable development.
