The production of fuels and chemical products must focus on a sustainable energy transition where all actors in society must be more responsible for the technologies and processes implemented in a current post-consumer market. There are various emerging technologies such as pyrolysis that focus on the treatment of different types of biomasses and plastic wastes which can be treated independently or by mixtures of two or more products and called as co-pyrolysis. The biofuels and bioproducts production from algae, lignocellulosic biomass and wastes may provide viable options in the value chain with good economic benefits. This review presents the variables that affect the pyrolysis process and the new emerging technologies in the production of biopropane and turquoise hydrogen (biomass hydrogen), as well as a review focused on their life cycle analysis. Some emerging technologies such as biomass intermediate pyrolysis polygeneration (BIPP) or Fluidized Catalytic Cracking to obtain biofuels for the electrical and thermal energy generation, as well as for the production of Bio-LPG, biofuels for ships, renewable propylene, and hydrocarbons biological aromatics (BTX: benzene, toluene, and xylene), are by instance essential for rubber production. Decarbonization helps to reduce emissions of CO2 and other greenhouse gases (GHG). The energy system takes biomass as a viable option to transform it into energy, based on two technologies: pyrolysis and gasification, where biomass plays a twice important role, that is, it is an energy producer and serves as a raw material to capture the CO2 emitted towards the atmosphere.
