Co-pyrolysis of plastics and food waste mixture under flue gas condition for bio-oil production

Growing global population increased the energy demand and generation of municipal solid wastes (MSW). MSW can be utilized to produce green renewable fuels via pyrolysis technology. This study investigated the co-pyrolysis of MSW represented by mixtures of food and plastic wastes, in a downdraft pyro...
