Dispose of Styrodur causes different costs depending on the age


The disposal of Styrodur is difficult due to a flame retardant that has been fire retardant in the past. After the toxicity became known, Styrodur, which contains this HBCD, was declared a hazardous waste in 2016. Newer Styrodur is made with another harmless flame retardant. That depends on the cost.

With or without toxic flame retardant

After discovering in 2013 that Styrodur contains the flame retardant hexabromocyclododecane (HBCD), which presumably produces dioxin during combustion, the foam boards were declared hazardous waste. Since summer 2015, alternatively, the agent polymer is used. All HBCD-containing panels must be disposed of in hazardous waste facilities. The procedure must also be documented in writing and in full.

In small quantities Styrodur is assigned to residual waste without HBCD and may be disposed of accordingly. In larger units, such as those incurred in a renovation or demolition, must be calculated with about twenty euros fee for each cubic meter of varietal Styrodur. Since adhesions of adhesives neutralize purity, the price quintuples for the resulting mixed waste.

Special waste is expensive

In recent years, the disposal costs for Styrodur have multiplied with HBCD. At the end of 2017, the average price was around eight euros per kilogram. The re-declaration of hazardous waste has created large bottlenecks that have led many incinerators to stop accepting old Styrodur.

The builder or renovating homeowner needs a takeover slip issued by the disposal company. If a craftsman disassembles the Styrodur, the client receives a copy. The path of the material must be completely documented from the place of origin to the final "delivery" at a waste incineration plant with special approval.

How the type of flame can be recognized

The manufacturer BASF has introduced several indications describing the type of flame retardant used:

  • A black rectangle on the label indicates HBCD-free Styrodur
  • In the batch number printed on the edge of the plate, the years 15 and 16 (second and third place after the prefix XX) indicate polymer
  • There is no separate notice box under the signature line on the technical explanatory sheet if polymer is included

Tips & Tricks

Sort not only the types of materials, but also different Styrodure, if available. Disposal companies always calculate the most expensive component in the case of mixed waste, which leads to expensive special waste rates, even for normal waste parts.
