“…The main technologies include incineration, landfilling, composting, anaerobic digestion, pyrolysis, and biochemical methods, along with recent developing technologies such as hydrothermal carbonization and supercritical water gasification [88]. Another application in energy is the use of food waste for green energy vehicles in the form of fuels to be used in internal combustion engine vehicles (running on biomethane or bioethanol), fuel cell vehicles (biohydrogen), and plug-in electric vehicles using bioelectricity [89]. These papers reflect the various technological routes and applications for energy recovery from food waste.…”

Over the last decade, the circular economy (CE) has attracted attention due to the current unsustainable model of production and consumption, which involves an increased resource use and depletion. Agri-food is one of the key sectors where action must be taken to ensure the transition to a more sustainable development model in line with circular economy principles. This study aims to evaluate the potential of implementing the circular economy in the pitahaya agri-food chain in Ecuador. The research was conducted from 2019 to 2021, during which a checklist was applied that included 91 items grouped into nine dimensions: source or supply of materials, design, manufacturing, economic circle, distribution and sales, consumption/use, 4R, remanufacturing, and sustainability. The level of the circular economy evaluated in the study was low (2.14 points out of 5). Therefore, improvements are required in the agri-food management of fruit cultivation and processing. Critical points were identified and strategies were proposed to increase competitiveness, improve environmental performance, and promote the implementation of the circular economy in this production chain. A final recommendation is to explore research on the concept of CE in the sector, mainly focused on the valorization of biomass as a contribution to the bioeconomy in order to contribute to the country’s growth within the context of sustainability.

“…Then, the second bed containing Al The integrated process to produce 282.5 t per d of octanoic acid was designed and simulated as an nth plant that can be scaled up based on experimental data and operated without unanticipated performance loss. 77 Highly pure 1-octene ( purity = 76.0-87.0 wt%) was produced via the hydrogenation of bio-based octanoic acid and subsequent dehydration of octanol in a dual-bed catalyst reactor. Owing to the excessive H 2 input required to ensure high hydrogenation activity at 20 atm, a large amount of unconverted H 2 existed in the reaction mixture (stream 4 in Fig.…”

“…Unlike the greenhouse gas (GHG) emissions from the conventional petroleum-based LAO production strategy, the GHG emissions from the CHP subsystem in the developed strategies are considered as biogenic CO 2 , and the excess electricity is considered as a carbon credit. 77 The four cases were analyzed in terms of four major environmental impact categories. The results of this analysis are presented in proportion to 100%, which is the maximum value set for each impact category (Fig.…”

Bu çalışmanın amacı yeşil hastanelerin gelişimi için önem arz eden stratejik unsurların belirlenmesidir. Bu kapsamda, ilk olarak detaylı bir literatür taraması gerçekleştirilmiştir. Yapılan bu incelemeler sayesinde, enerji bazlı dört farklı faktör tespit edilmiştir. Bu kriterler karbon emisyonunun azaltılması, temiz enerji kullanımı, enerji verimliliğinin sağlanması ve düşük enerji tüketen ekipmanların seçilmesi şeklindedir. Bu kriterler arasından en önemlilerinin tespit edilebilmesi için DEMATEL yöntemiyle bir analiz gerçekleştirilmiştir. Sonuç olarak, yeşil hastanelerin gelişebilmesi için en fazla önem arz eden kriter temiz enerji kullanımıdır. Ayrıca, karbon emisyonunun azaltılması da önem arz eden diğer önemli bir faktördür. Elde edilen bu sonuçlardan anlaşılabileceği üzere, hastanelerin temiz enerji kullanımına acilen geçmeleri gerekmektedir. Bu süreçte, küçük ölçekli güneş panelleri dikkate alınabilmektedir. Bu paneller sayesinde, hastaneler hem kendi enerjilerini üretebilmekte hem de kullanılan enerji çevre dostu olabilmektedir. Bu bağlamda, yapılacak kapsamlı araştırma ve geliştirme çalışmaları sayesinde, bu enerji türlerinin maliyetlerinin düşürülebilmesi mümkün olabilecektir. Belirtilen bu hususa ek olarak, vergi indirimi ve düşük faizli kredi kullanımı gibi devlet teşvikleri sayesinde, küçük ölçekli güneş panellerinin maliyet avantajı elde edebilmesi mümkün olabilecektir.
