Catalytic pyrolysis of plastic waste: Moving toward pyrolysis based biorefineries
R. Miandad,Mohammad Rehan,Mohammad Abou El-Fetouh Barakat,A.S. Aburiazaiza,Hizbullah Khan,Iqbal M.I. Ismail,Jeya Dhavamani,Jabbar Gardy,Ali Hassanpour,Abdul-Sattar Nizami +9 more
TL;DR: In this paper, the catalytic pyrolysis of different types of plastics waste (PS, PE, PP, and PET) as single or mixed in different ratios in the presence of modified natural zeolite (NZ) catalysts was carried out in a small pilot scale pyro-lysis reactor, where the NZ was modified by thermal activation (TA-NZ) at 550°C and acid activation with HNO3 to enhance its catalytic properties.
Journal ArticleDOI
Food waste to biochars through pyrolysis: A review
TL;DR: In this article, the potential opportunities for food waste pyrolysis focusing on the conversion of food waste to biochar products were evaluated. But the authors did not consider the food waste composition and the process conditions.
Journal ArticleDOI
Bio-based fertilizers: A practical approach towards circular economy.
TL;DR: In order to effectively implement technologies based on biological resources, it is necessary to construct small wastes solubilization or fertilizer installations at the site of waste generation, which will solve the problem of waste transport or sanitary hazards.

Top Value Added Chemicals from Biomass: Volume I -- Results of Screening for Potential Candidates from Sugars and Synthesis Gas
Todd A Werpy,G. Petersen +1 more
TL;DR: In this paper, the authors identified twelve building block chemicals that can be produced from sugar via biological or chemical conversions, and the twelve building blocks can be subsequently converted to a number of high-value bio-based chemicals or materials.

Production of first and second generation biofuels: A comprehensive review
Satya Narayan Naik,Satya Narayan Naik,Vaibhav V. Goud,Vaibhav V. Goud,Prasant Kumar Rout,Ajay K. Dalai +5 more
TL;DR: In this paper, a review of cost effective technologies and the processes to convert biomass into useful liquid bio-fuels and bioproducts, with particular focus on some biorefinery concepts based on different feedstocks aiming at the integral utilization of these feedstocks for the production of value added chemicals.
Journal ArticleDOI
An overview of second generation biofuel technologies.
TL;DR: The biochemical route, being less mature, probably has a greater cost reduction potential than the thermo-chemical route, but here a wider range of synthetic fuels can be produced to better suit heavy truck, aviation and marine applications.
