In this research article, design and fabrication of material separation machine is discussed with the objective to decrease the time, money, and labor required to separate waste materials from one location to another, the design and manufacture of material separation machines are explored in this study. The fundamental concept was inspired by the development and application of artificial intelligence as well as the motion of robotic arms. The Material Separation machine's design places an emphasis on separating recyclable and usable waste from the accessible trash while using less energy and scientific approaches to separate the valuable material. The device is helpful for the efficient use of time and human labor, as well as for areas where a lack of manpower is a concern. Compared to other existing Material Separation machines, our machine utilizes cheap, readily available materials in the best way possible to produce an effective outcome in a predetermined amount of time.

Renewable form of energy is becoming more curious for researchers. Biofuel can be used in different sectors to meet energy demands and provides less dependency on fossil fuels. Many countries in the world are capable to produce biofuels from biomass and other sources. Generations of biofuels are important for the development of bio-based fuels. Biodiesel is produced by the three-step process or transesterification process. Some parameters directly affect the production of biofuels. Biofuels have emerged as a promising alternative to conventional fossil fuels, offering potential solutions to environmental and energy security challenges. The production and utilization of biofuels involve various influencing parameters that affect their characteristics and performance. The cost of the feedstock, food security, use of catalyst, and some other parameters are to be considered for the production of biodiesel. This article provides information about feedstock available in different countries for production and also suggests the use of additives can also enhance the properties of first, second, and third-generation biofuels.

The depletion rate of fossil fuels are very high as well as they put negative impact on the environment. So the alternate fuels are required to meet the demand of the world. The bio based fuels and blends are the source which can be help for the sustainable development. The mild negatives of biodiesel, like its increased nitrogen oxide emissions, inconsistency with winter conditions, and frequent replacement cycles for engine parts like fuel filters, fuel tanks, and fuel lines owing to clogging, exceed its many advantages. By using nanoparticles as fuel additives, there is still room to improve the qualities of fuel and address its shortcomings. The role of nanoparticles additives increases the thermos-physical properties of the pure fuel, bio based fuel and blends. They directly affect how well the diesel engine performs. There are various nanoparticle additions that play diverse roles in the operation and emission process of the diesel engine. The common nanoparticles additives such as cerium oxide, aluminium oxide, magnesium, carbon nano tubes are the common additives which are directly used. This review article analyses the performance, emission traits, fuel characteristics, and issues with the nanoparticle additions. Additionally, this work aids researchers in their investigation of potential nanoparticle additions in the future.
