Renewtec has made an inventory of techniques related to gasification of  Shredder Light Fraction (SLF) to a client who wants to remain confidential.

According to Swedish legislation shredder products containing more than 10% of organic carbon is not allowed to be deposited, it should be recovered (material or energy). End-of-Life products such as cars undergo a shredding process which result in shreeder light fraction containing plastic parts, textile, rubber etcetera.

SLF contains metalls, including heavy metals, but also substances that normally aren’t associated with gasification feedstock, such as bromine originating from flame retardants. SLF has normally a high content of ash and chlorine resulting in an increased risk for agglomeration, sintering, fouling, build up of depositions and corrosion.
