Plastics recovered from kerbside collection of recyclables are generally an ideal feedstock for Thermo Fuel. However, given the appreciable market value of PET these are generally sorted and removed first. The commingled plastics that remain after undesirable and other use plastics have been recovered, can be processed easily by Thermo Fuel. Once PET and PVC are removed, there is generally no need to identify plastics by type for it to be suitable for Thermo Fuel processing. It is worth noting that the majority of unsuitable feedstock plastics are generally very rare in the common waste stream. Contamination such as organic matter or paper can be tolerated, but these will have an effect on yield and sulphur levels and should be less than 10% by weight.
