“…Polyethylene, the main product produced from petrochemical ethylene, performs rather poorly in this sense, as it cannot be easily selectively depolymerised to its monomer (i.e. ethylene), making chemical recycling challenging ( polyethylene can be deconstructed by pyrolysis, but this typically yields a complex mixture of products 327 ). Furthermore, polyethylene is not Table 2 Ranking of fermentation processes based on their potential to be applied for the production of bulk chemicals in the 2050 circular economy.…”

This paper examines the degradation trends of polymeric materials during heat conversion and solvolysis processes. The presence of different fractions of polymeric materials, such as PET, PP, SBR, ABS, resin, and tier waste, necessitates the use of different procedures for degradation, transformation, and further elimination from the natural environment. A significant part of the work was devoted to discussing the issue of thermal pyrolysis, taking into account the chemical composition and the possible impact of the process reaction mechanism, the type of raw material used, and the influence of the process temperature on the yields of low, medium, and high boiling products. The issue was extended to the possibility of decomposition of polymers based on the use of catalytic additives for the improvement and efficiency of the process and the structural modification of reactors. The major goal of this investigation of these various options was to generate a spectrum of accessible strategies for polymeric material degradation. The optimal technique depends on the polymer type and predicted final product qualities. Different catalysts, such as ZSM-5 (Zeolite Socony Mobil-5 one of the most efficient catalysts), ZSM-5 with ammonium groups, and ZSM-5 with 10% Ni, improved the efficiency of several heating processes. The final products after polymeric material degradation were determined by the type and conditions of the degradation processes, results of the materials characterisation, and the scale of the reactors utilised.

“…Among them, plastic residues emerge as the most economical and environmentally friendly option, because of their large consumption around the world. It is estimated that the worldwide generation of plastic-based waste is around 1.3 billion tons per year, and a value of 2.2 billion tons is expected over the next few years [162].…”

“…Spent FCC and larger-pore zeolites are suitable for obtaining liquid hydrocarbons; zeolites being especially appropriate due to large specific surface areas, thermal stability and high acidity. In addition, the cooperative action of these properties can be adjusted to promote bio-oil formation and/or to inhibit solids production [13,162].…”

The pyrolysis of lignocellulosic biomass is a promising technology for obtaining renewable chemicals and fuels to replace fossil-based products. However, due to the complexity of the lignin, cellulose and hemicellulose molecules, a large variety of compounds are often formed, making commercial implementation difficult. The use of a catalyst during reactions has been recognized as one of the major improvements in pyrolysis, allowing the production of selected compounds. Moreover, the large number of available catalysts opens up a wide range of possibilities for controlling the reaction network. Zeolites, hierarchical zeolites, alkali and alkaline earth oxides, transition metals and carbonaceous materials, among others, have been investigated in the pyrolysis of a variety of biomasses. In addition, bifunctional catalysts play a role in pyrolysis, as well as the addition of plastics as hydrogen donors. This review aims to present and discuss in detail state-of-the-art catalytic pyrolysis, focusing on the relationships between the properties of the catalysts and the obtained products. A guideline for selecting catalysts for lignocellulosic biomass is also provided.
