EPS is an expanded hard material with reduced weight, derived from petroleum composed only by carbon and hydrogen atoms. It is a closed-cell structure able to retain air inside. For its production are used water vapour and pentane, which evaporates at the end of the expansion process. It is shown up in blocks, panels or formed products, consisting of small spherical beads welded.


On one hand, waste is one of the main problems of the production system, while on the other hand, the LCA approach, already during the designer’s stage, helps to define how to improve the system in order to reduce not only the environmental impact but also the economic and social ones connected to the end-of-life management. One of the ways to limit the environmental impacts is recycling, which purpose is to reuse material from waste, to bring them back to the production system (that could also be different from the initial one), so making them secondary raw material.



After a grinding phase and an eventual blending of EPS scraps with virgin material, this could be inserted in an extruder, to obtain a granulated product. The extruder consists of a cylinder with sectors of different temperatures, through which the EPS is passed, to make it homogenized without degrading.


It is a very common practice that consists of the reduction of the EPS scraps almost at the level of a single pearl and mixing them with pearls of virgin material, in different quantities depending on the desired product. Resale to our suppliers to produce new pieces.

ASTM E 84-19b – USA certification

The American Society for Testing and Materials (ASTM), is a globally recognized leader in the development and delivery of international standards.
Today, ASTM standards are used around the world to improve product quality, increase safety, facilitate market access and trade, and build consumer confidence.
The standard certifies the combustion characteristics of the surfaces of building materials.

NFPA 286-2019 – USA certification

This standard describes a method for determining the contribution of interior finishing materials to fire growth in the environment during the specified fire exposure conditions.
It is intended for the evaluation of the flammability characteristics of internal finishes of walls and ceilings, other than textile wall coverings, where such materials constitute the visible internal surfaces of buildings. This test is also known as the “corner of the room” test.
