Diverse opportunities and environmental impacts could occur from a potential move towards waste-to-energy (WtE) systems for electricity generation municipal solid waste (MSW) in Lagos Abuja, Nigeria. Given this, the purpose of this study is to use life cycle assessment (LCA) as primary analytical approach order undertake comparative analysis an impact perspective different WtE scenarios, along ...

Background Biofuels from hydrothermal liquefaction (HTL) of abundantly available forest residues in British Columbia (BC) can potentially make great contributions to reduce the greenhouse gas (GHG) emissions from the transportation sector. A life-cycle assessment was conducted to quantify the GHG emissions of a hypothetic 100 million liters per year HTL biofuel system in the Coast Region of BC....

The purpose of this study is to determine the energy use efficiency and greenhouse gas (GHG) emissions in peach production that took place Kırklareli province Turkey during 2020-2021 season. This includes calculations input, output, efficiency, specific energy, productivity, net input types, GHG ratio. Survey, observation data are related obtained from were collected 16 different farms (reachab...

This study assessed the environmental performance and energy efficiency of electricity generation from rice straw using a combined gasification internal combustion engine (G/ICE). A life cycle assessment (LCA) was performed to consider conversion straw, production which based on Philippine farming practice. Rice is treated as milled coproduct assumes an burden allocated by mass. The results imp...

the purpose of this paper is multi-objective optimization of refrigeration cycle by optimization of all components of the cycle contains heat exchangers, air condenser, evaporator and super-heater. studied refrigeration cycle is compression refrigeration cycle of unit 132 third refineries in south pars that provide chilled water for cooling refinery equipment's. cycle will be performed by ...

• A novel system is proposed and evaluated for biocrude production. N, O, S content decreased via ozone-air flotation catalytic HTL. Biocrude aliphatic compounds doubled vs sedimentation. The NER value bio-jet fuel was half than jet-fuel. carbon footprint three times lower use of microalgae harvesting investigated, in terms its environmental feasibility determined by the Net Energy Ratio (NER) ...

Microalgae are rapidly being employed in carbon fixation due to their benefits over other crops for energy needs, such as high photosynthetic efficiency, massive biomass production and rapid development. Spirulina maxima is a microalgae whose based on cultivation with favorable growing conditions. Within the Life Cycle Analysis, steps that fed into Impact 2002 system included assembly cultivati...
