The disposal of UFO is a global and major environmental issue due to the straightforward dumping of the UFO into drains. Waste management issues are getting worse and endangering environmental preservation. Recycling UFOs could relieve disposal issues, but more importantly, it would improve the efficient usage of agricultural and food reserves. Most of the UFO's hazardous chemicals are oxidation products of free fatty acids (FFA), particularly polyunsaturated fatty acids. One of the main issues in the refinement of edible oil is the FFA concentration. It has also frequently been used to describe the oil's quality and suitability for food purposes. FFA is derived from triacylglycerol by cleavage of ester bonds due to the action of high temperature, oxygen and moisture. To reduce FFA, UFO is pre-treated by physical filtration, adsorption, heating, neutralisation, degumming, bleaching (whitening) and chemical treatment. In a base-catalysed system, it is preferable to have less than 1% of FFAs by weight of oil, or it will interact with the catalyst and produce soap. To enhance the quality of frying oil and UFO, numerous active filtering methods, or adsorption procedures have been researched. Bio-adsorption is economical, easily designable, environmentally friendly and is even an effective technique in the presence of competitive ions. Ions and molecules physically attach to or connect with surfaces during adsorption. The sorption capacity depends on the type of bio adsorbent and the nature of the oil. This review paper discusses the potential of four types of bio adsorbents which are coconut shell, palm kernel shell, rice husk, and bagasse in reducing FFA content in UFO. These materials possess a large surface area, which provides ample site for adsorption. The interaction and adsorption of FFAs are made easier by the presence of active sites such as hydroxyl (-OH) and carboxyl (-COOH) groups on the surface.

Since indoor farming uses artificial environment, it faces many difficulties such as getting the right amount of water, light, temperature, and humidity that are required by crops. These factors highly affect the proper growth and development of crops, its quality, and the output yield. There are existing indoor vertical farming facilities that can mimic the natural environment but don’t address the efficiency and cost of the overall system. In this study, an existing indoor vertical farming was modified by designing a low-cost smart monitoring and control system that uses machine learning technique to autonomously control the actuators such as the cooling fans, water valve, and LED lights based on the following descriptors: temperature, humidity, soil moisture level, and the health status of the Lactuca sativa L. or commonly known as lettuce. The modified system achieved a better growth compared to the traditional method. The height, length and width of the lettuce is found to be better by 20 % and the color of the system’s output is greener than the usual. The cost incurred is 54 % and 19 % cheaper with regards to the energy consumption and the water consumption. © 2023, AIDIC Servizi S.r.l.}, year = {2023}, eissn = {2283-9216}, pages = {535-540} } @article{MTMT:34541397, title = {Improving the Sustainability of Acetone Recovery}, url = {https://m2.mtmt.hu/api/publication/34541397}, author = {Hégely, László and Karaman, Ömer Faruk and Láng, Péter}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {105}, unique-id = {34541397}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {295-300} } @article{MTMT:34487709, title = {Capacity Expansion for Sustainable Development in Family Businesses – Recyclable Packaging Materials in Food Industry}, url = {https://m2.mtmt.hu/api/publication/34487709}, author = {Nemes, Kinga and Konczosné Szombathelyi, Márta}, doi = {10.3303/CET23107031}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34487709}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {181-186} } @article{MTMT:34487529, title = {The Theoretical Framework of Sustainable Financial Development Through Literature Outlook}, url = {https://m2.mtmt.hu/api/publication/34487529}, author = {Szalai, István and Feketéné Czakó, Katalin}, doi = {10.3303/CET23107100}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34487529}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {595-600} } @article{MTMT:34487453, title = {Identifying Driver Behaviours Contributing to Road Safety Among Different Modes at Road Junctions, Peri-Urban Areas, Thailand}, url = {https://m2.mtmt.hu/api/publication/34487453}, author = {Pawinee, Iamtrakul and Makó, Emese and Sararad, Chayphong}, doi = {10.3303/CET23107099}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34487453}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {589-594} } @article{MTMT:34487253, title = {Optimizing Topology of Structures Considering FatigueResistance}, url = {https://m2.mtmt.hu/api/publication/34487253}, author = {Habashneh, Muayad and Movahedi Rad, Majid}, doi = {10.3303/CET23107103}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34487253}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {613-618} } @article{MTMT:34487005, title = {Introducing the Walkability Index, an Index That Measures the Walkability of Public Spaces}, url = {https://m2.mtmt.hu/api/publication/34487005}, author = {Hideg, Viktória and Makó, Emese}, doi = {10.3303/CET23107098}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34487005}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {583-588}, orcid-numbers = {Hideg, Viktória/0009-0007-3681-7935} } @article{MTMT:34486955, title = {Overview of XBRL Taxonomy Usage for Structured Sustainability Reporting in European Filings}, url = {https://m2.mtmt.hu/api/publication/34486955}, author = {Suta, Alex and Pintes, Orsolya and Péter, Molnár and Bence, Lukács and Loránd, Kedves and Tóth, Árpád}, doi = {10.3303/CET23107097}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34486955}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {577-582} } @article{MTMT:34486874, title = {Cooperation and Sustainability in Last-Mile Logistics Sector: Behavioural Aspects of Courier Express Parcel Service Providers}, url = {https://m2.mtmt.hu/api/publication/34486874}, author = {Bartucz, Csilla and Süle, Edit}, doi = {10.3303/CET23107095}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {107}, unique-id = {34486874}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {565-570} }
