Today, waste plastics represent a promising source both for energy production and chemicals. One way to use their potential is pyrolysis under well-defined conditions. This work presents a suitable method for treat-ment of waste polyethylene terephthalate (PET) using low-temperature pyrolysis realized by heating rates of 5 °C min-1 (slow pyrolysis) or 25 °C min-1 (fast pyrolysis) up to final temperature of 400 °C. Under these con-ditions, the valuable products were formed, namely solid fuel with HHV 31-33 MJ kg-1 and liquid mixture containing mainly ethylene glycol and aldehydes. While slow pyrolysis provides mainly solid fuel, ethylene glycol and aldehydes, main products of fast pyrolysis are solid fuel and paraldehyde.
