The recycling of foam boards has always been a headache. This kind of waste is usually very large, not only used to make foam insulation boards, but also contains some waste packaging. For example, the packaging of large furniture also contains many foam boards. The Environmental Protection Agency estimates that we produce more than 3 million tons of polystyrene every year and unfortunately, most of this is not recycled when it could be! And this kind of large foam board is more difficult to recycle than small packaging and leftovers.

The process of recycling foam board mainly involves the recycling of two types of foam, EPS foam board and XPS foam board. According to the major types, both types of foam belong to PS, but the materials used in the manufacturing process are different. EPS mainly adopts foaming process, and XPS adopts extrusion process. However, there is no doubt that the two have one thing in common, that is, both can be 100% recycled by foam densifier. As for why some foam boards are discarded at will, it may be due to disregard for environmental protection and failure to find suitable tools for recycling.

Foam densifier has a remarkable effect on the heating, melting and recycling of EPS foam board or XPS foam board. Put the foam board into the GREENMAX foam densifier. First, the sharp knife in the crushing device will directly break the waste into small pieces , and then enter the heating device part for heating and melting, and finally extruded and cooled to become dense ingots, the compression ratio can reach 90:1.

Generally, the foam recovered by hot-melt technology has relatively high compression, and the selling price is also the highest. Usually, the sales of foam ingots are several times that of loose foam, which is one of the main reasons for the popularity of GREENMAX foam densifier. The foam processed by this equipment is usually used as a valuable recycled material mixed with new materials and put into new manufacturing link.
