EPS Melting Machine: An Effective Solution for Maine’s Construction Waste Landfill Problem

In the 192nd legislative session and throughout previous sessions, Maine has decided to close a local landfill and refuse to accept construction waste from Massachusetts. This decision stems from the fact that 200,000 tons of construction waste occupy a significant portion of Maine’s landfills each year. Consequently, Maine will also reject waste shipments from other states to conserve landfill space.


The Challenge of Foam in Construction Waste

A substantial portion of construction waste consists of foam. EPS foam and XPS foam are two prevalent types of construction waste. These foams are typically mixed with cement and used as insulation boards in buildings. The complaints about the large volume of construction waste are justified, as foam materials contain 98% air, occupying significant landfill space.


Recycling Inefficiencies

Many types of waste are not efficiently recycled, partly due to ineffective waste classification and outdated recycling technologies. For example, polystyrene foam, a common plastic foam, has long been advocated for recycling in the U.S., but its recycling rate remains below 50%. Common sources of polystyrene foam waste include the restaurant, fishing, and agricultural industries. Much of this waste ends up in landfills or incinerated, posing risks to the environment and human health.

The Role of EPS Melting Machines

Therefore, people will focus on the foam compactors, EPS compactors are specifically designed to solve the large volume of foam difficult to store and recycle.The process begins with shredding the waste foam materials into uniformly sized pieces in the machine’s crushing chamber. The pieces are then melted into a liquid gel using a hot melt unit. This is then extruded through a screw, which compresses the foam to 1/50 of its original volume.

We recommend the Qinfeng EPS Compactor,CF-HM400 Melting Machine. The CF-HM400 uses four-axis crushing blades and is suitable for medium-sized recycling centers. It can process materials such as EPS, EPE, and EPP (with an optional frequency converter), reducing waste volume by 80-90%. This equipment is efficient, space-saving, environmentally friendly, and operates without emissions, avoiding secondary pollution.

Benefits for Maine

By implementing such technology, Maine can effectively and conveniently address its landfill capacity issues, significantly mitigating the environmental impact of construction waste,promoting sustainable waste management practices.
