“…A component of various solid-energy-generating matrices, MBM, through combinations with coal or biomass, is a friendly solution of elimination by energy recovery for environment and quality of life [ 27 , 28 ], and this work confirms these aspects through experimental data. The choice of MBM for this study is related to the addition of this type of waste with biomass, and in the case of combustion or co-combustion of pyrolysis products, the carbon footprint is neutral [ 29 ]. Other food waste (rice, vegetables, and fish) was blended in definite ratios (70:30, 60:40, and 50:50 w/w) with polyethylene terephthalate (PET) to develop a process for producing bio-oil, char, and value-added chemicals using co-pyrolysis under controlled conditions [ 30 ].…”

The capitalization of agri-food waste is essential for the sustainability of a circular economy. This work focuses on a solution to eliminate such waste, meat and bone meal (MBM), which is produced in large quantities by the food industry and is prohibited for use as animal feed under the European directives. Therefore, with the focus of converting waste to energy, the catalytic pyrolysis of MBM in the presence of mesoporous silica nanocatalysts (SBA-3 and SBA-16 materials and metallic derivates) was investigated in a home-made reactor for the production of renewable energy. The mesoporous silica materials were synthesized using relatively simple methods and then characterized in order to determine their morpho-structural characteristics. The MBM pyrolysis behavior under different experimental conditions was examined in detail, both in the presence and absence of the new catalysts. The resulting MBM-based pyrolysis products, MBMPYOILs and MBMPYGASs, were also assessed as potential alternative fuels, highlighting comparable energy values to conventional fuels. The outcomes of this investigation offer a potential pathway to the clean production of gas and oil, thus promoting the high-grade utilization of MBM waste.

“…In agriculture, biochar can be used as a soil repairer for sustainable agricultural production [8]. Biochar can modify soil characteristics [9], stores nutrients and promotes carbon availability [10], and reduce the bioavailability of various soil toxins [11]. Although, there are potential toxicants and resulting in unintended impacts on the environment [12].…”

Lampung Selatan Regency is one of the centers of corn production in Lampung, Indonesia. Along with the increase in corn production, the resulting corn biomass waste also increases. Corn biomass waste such as cobs can be utilized into more useful products such as biochar which is useful as a soil amendment. The purpose of this research was to evaluate the quality of biochar based on its production technique. The three biochar production techniques used were traditional soil pit, closed drum kilns, and open drum kilns.. The quality of biochar was determined by the temperature and period of the pyrolysis process, which was greatly influenced by the selected production technique. The results showed that the closed drum kiln technique produces biochar with better properties for increasing soil fertility because it produces the biochar with the highest fixed carbon and CEC.

“…Bio-oil was originally supposed to be a substitute for petroleum fuels due to its similar appearance and properties. Bio-oil needed to be refined before it could be used as a drop-in fuel because of its fluidity, calorific value, and corrosiveness [10]. Researchers have developed a number of upgrading processes, including catalytic cracking, catalytic pyrolysis, hydrodeoxygenation, supercritical fluids, and esterification [11,12].…”

The properties of bio-oil distillation and product distribution are critical for parameter optimization and reaction conditions. In this work, low-reaction temperature of 96, 97, 98, 99, and 100 °C was conducted. The slow pyrolysis process at 500 °C with a 1 hour holding period yielded the coconut shell bio-oil employed in this research. The characteristic components of bio-oil were thoroughly evaluated using gas chromatography-mass spectrometry (GC-MS). The research founded that during the distillation reaction process, a similar critical point was thoroughly established, which might be attributed to the steady system created by the hydroxyl group. As a result, bio-oil distillation might be divided into 3 stages: steady, explosive, and heating. The content of acetic acid, 2-Furancarboxaldehyde, and phenol are dominated. Acetic acid yield showed an increase, followed by the distillation reaction temperature. Phenol yield was also observed as a dominant product in the bio-oil. The higher phenol yield was observed at a temperature of 98 °C is 38 %. The observed phenomena could be related to the oxidation of hemicellulose, cellulose, and lignin to form phenol, the bio-major oil component. The specific distillation properties and product distribution provide a great look at the reaction process and component enrichment patterns, which can aid formulation and parameter adjustment.
