Fossil fuels have provided humans with an enormous and stable primary energy source to rapidly develop advanced technologies, increasingly efficient machines industries, as well greater varieties of consumer products. While enjoy the conveniences modern world, critical global issues also been created, such exponential hike in waste generation, rapid depletion finite fossil fuels, environmental pollution, climate change. Two major anthropogenic wastes are biomass plastic waste. Each year, 464 million tonnes generated globally, only 20% recycled, 25% incinerated, while 55% landfilled. Likewise, 140 billion from agriculture sector 181.5 lignocellulosic forestry agricultural residues produced worldwide annually, 40% 4.5% reuse respectively. This mountainous underutilised presented a good opportunity for recycling into biofuels instead landfilling or open dumping, thus promoting circular bioeconomy. Pyrolysis stands out promising thermochemical route synthesize biofuels, co-pyrolysis benefits synergistic interactions between both feedstocks, enhancing yield quality biofuels. Therefore, this review, mechanism is described, recent advances field comprehensively presented. The importance applying bioeconomy frameworks on highlighted.

Biodiesel is a renewable alternative biofuel to conventional fossil fuel. can be produced through esterification and transesterification reactions mainly catalyzed by acid, alkali, enzyme catalysts. Among all of these catalysts, catalysts are more advantageous than chemical (alkali acid catalysts) due their high selectivity, mild reaction conditions, lower energy consumption, yielding good quality products with no side reactions. However, because the costs enzymes, there limit on use enzymatic operation an industrial scale. The cost enzymes reduced improving lifespan Over last few decades, significant developments in enzyme-based biodiesel synthesis have been attained both laboratory scale, production also reduced. This review gives overview immobilized lipase-catalyzed lipase-inorganic hybrid nanoflowers production, including economic viability idea about different reactors which used for reaction.

It is no longer unfamiliar to the world that usage of fossil-derived fuel accompanied by several downsides, including environmental fatality associated with toxic gas emissions from diesel engines and recurring surging price fuel. The concern regarding exploitation natural resources subsequent threats has caught attention all nations. Therefore, scientists have stepped forward come up most suitable alternative conventional They utilized abundance oil feedstocks performed transesterification reactions short-chain alcohols produce less toxic, eco-friendly termed Biodiesel which was considered be a viable substitute. In order carry out reaction feasibly, certain homogeneous heterogeneous catalysts were employed. Heterogeneous got more recognition among researchers; however, many these did not attain large-scale production. Among catalysts, calcium oxide (CaO) appeared one solid base for biodiesel synthesis. CaO can derived chemically as well sources such chicken eggshells, snail shells, biont shells more. exhibits high catalytic activity perform reactions. Additionally, cheap catalyst also used support material various systems. Constructing effective CaO-based industrial production unlocks scope process advancements in this area.
