“…The biggest contributor to this waste is the non-biodegradable plastic packaging utility and the unavoidable use of plastic in daily life as well. An issue of particular consideration is that wasted plastic reaches 26,500 tons per day in Indonesia [3]. The waste causes carbon storage reduction of the seas as well as severe damage to many living things.…”

Nowadays, it is important to reduce and replace plastic in the food manufacture industry. However, the development of new material is less than satisfactory. This paper aims to analyze the key factors for the development of new material for the food production package. A survey was conducted to gather data to test the factors in the development of new material for food production package identified by literature review, expert interviews, and distribution questionnaires to respondents. The questionnaire uses a Likert scale and the cluster sampling method. The analytical tool used is factor analysis. The results show that the key success factors are different from the developed country. The government was expected to have a significant effect on the development of new material, the public or consumer placed second.

“…Naturally occurring silica‐rich zeolites, such as clinoptilolite and mordenite, are studied as potential catalyst materials because they are readily available and inexpensive [99] . Natural zeolites in the protonated form have been used for PP, HDPE, LDPE, PS, PP/HDPE, EVA, and PET degradations and have shown moderate cracking ability and improved yields of liquid product, while also increasing char production [98,99,107,111,112,182–194] . However, catalyst efficiency has been strongly correlated to p/c ratio [191,192] .…”

“…For example, higher temperatures can increase the aromatization of alkanes and the production of hydrogen gas (Figure 10). [27,109,128,187,231,242] In addition, higher temperature has been found to reduce char production while increasing liquid yield [187] . Along with operating temperature, heating rates have been found to impact polymer degradation.…”

, respectively. Her graduate research focused on the fundamental understanding of deoxygenation mechanisms for biomass probe molecules on single crystals and thin films. During her graduate career, she received the DOE Science Graduate Student Research (SCGSR) award (2019) and conducted surface science research at Brookhaven National Lab. She now is a postdoctoral researcher at the University of Wisconsin-Madison. Her research focuses on surface spectroscopy and controlled design of heterogeneous catalysts. Melissa C. Cendejas received her B.A. (2016) in Chemistry and English from Williams College. There, she worked on the synthesis of conjugated organic molecules and phosphorusbased surfactants. She then started her PhD in Chemistry at the University of Wisconsin-Madison under the supervision of Prof. Ive Hermans. She studies active site formation on boron-based catalysts. She received the DOE Office of Science Graduate Student Research (SCGSR) award (2020) to perfrom in situ x-ray spectroscopy of catalysts at Stanford Synchrotron Radiation Lightsourse. Prof. Dr. Ive Hermans obtained his Ph.D. from KU Leuven University in Belgium in 2006. In addition to his scientific education, he also holds a postgraduate degree in Business Administration (KU Leuven, 2006). After postdoctoral research on in situ spectroscopy and reaction engineering with Prof. Alfons Baiker, he became assistant professor for heterogeneous catalysis (spring 2008) at ETH Zurich in Switzerland. January 2014, Prof. Hermans moved to the University of Wisconsin-Madison, holding a dual appointment in the Department of Chemistry and the Department of Chemical and Biological Engineering. His group focuses on the mechanistic understanding of catalytic technology using a variety of techniques.

“…Spouted bed reactors have been applied successfully for pyrolysis of polymers like PS, PE, PP, and PET due to their low bed segregation and low attrition in comparison with bubbling fluidized beds [120] . The CSBR design is relatively simple, and it is suitable for the pyrolysis of waste plastics without segregation of the wastes [126] . The CSBR is suitable for the pyrolysis of waste plastics without defluidization.…”

Recent Trends in the Pyrolysis of Non‐Degradable Waste Plastics

Waste plastics are non‐degradable constituents that can stay in the environment for centuries. Their large land space consumption is unsafe to humans and animals. Concomitantly, the continuous engineering of plastics, which causes depletion of petroleum, poses another problem since they are petroleum‐based materials. Therefore, energy recovering trough pyrolysis is an innovative and sustainable solution since it can be practiced without liberating toxic gases into the atmosphere. The most commonly used plastics, such as HDPE, LDPE (high‐ and low‐density polyethylene), PP (polypropylene), PS (polystyrene), and, to some extent, PC (polycarbonate), PVC (polyvinyl chloride), and PET (polyethylene terephthalate), are used for fuel oil recovery through this process. The oils which are generated from the wastes showed caloric values almost comparable with conventional fuels. The main aim of the present review is to highlight and summarize the trends of thermal and catalytic pyrolysis of waste plastic into valuable fuel products through manipulating the operational parameters that influence the quality or quantity of the recovered results. The properties and product distribution of the pyrolytic fuels and the depolymerization reaction mechanisms of each plastic and their byproduct composition are also discussed.
