Process integration is an interesting option to reduce costs and improve the economic viability of new processes in sugarcane mills. Brazil has a prolific sugar‐energy sector, with hundreds of sugarcane mills that could possibly act as sources of carbon, energy, and water for annexed plants. While many studies analyze the integration of new technologies into sugarcane biorefineries as greenfield plants, the assessment and establishment of integrated processes into existing plants will help detecting process bottlenecks and enabling the required levels of integration to be better understood prior to designing a full‐scale, greenfield biorefinery. The present review provides an overview of the possibilities for sugarcane mills to diversify the portfolio of products from sugarcane biomass – beyond ethanol, sugar, and electric energy. The work initially considers the integrated production of market‐ready sugarcane‐derived products, such as animal feed, industrial salts, and hydrocarbons in existing Brazilian plants. Finally, the study outlines the prospects for future integration of non‐traditional process alternatives in sugarcane mills, namely bioplastics, organic acids, molecular hydrogen, and advanced lignocellulosic compounds. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

Summary The economic, social, and environmental aspects are important that should be notable before the selection of a method for the production of energy. Various renewable energy sources are used like hydropower, biomass, biofuel, geothermal energy, and wind energy for the production of sustainable energy that are excellent approaches to fulfill energy environmental energy demands. Renewable sources of energy give an excellent chance to extenuate the gas emission in greenhouse and reduction of global warming with the help of renewable sources of energy. The importance and utilization of the variety of renewable sources of energy are elaborated in this article. The emerging and exploring technique for the production of energy is the photocatalysis. In photocatalysis, solar spectrum is the extraneous source that is used with water to produce hydrogen energy (green energy) by the water splitting under the shower of the solar spectrum. The solar spectrum contains heat and intensity of light from which light spectrum is the abundantly used for the splitting of water. The photocatalyst is the key factor to initiate the reaction depending upon the energy band gap by absorbing the energy from the spectrum of the sun. Semiconducting materials having lower forbidden energy band gap are the basic requirements to use them as a photocatalyst for photocatalysis. Copper vanadate and their composites are the promising materials that are used as photocatalyst for the production of hydrogen energy. Copper vanadate is the focusing material that can be used as photocatalyst. It is an n‐type semiconducting material with 2 eV indirect energy band gap having monoclinic structural phase which is tuned by the doping of metals like chromium, molybdenum, and silver to reduce the grain size and energy band gap and increase the surface area and optical absorption of solar light only to enhance the photocatalytic performance towards the production of hydrogen energy by water splitting in the presence of solar light.

This paper assesses the biojet fuel production potential in Brazil. It evaluates feedstock availability by applying a georeferencing analysis, and determines the cost-effectiveness and greenhouse gas (GHG) emissions of selected production routes throughout their entire life cycle. This study identifies and locates Brazilian hotspots in terms of bioenergy availability and proximity to the main sites of fuel consumption and handling in the country. Findings show that the biomass availability for each crop in the hotspots would be sufficient to feed the biojet conversion plants proposed in this study. The biojet production potential in the hotspots would represent 48% of the country's jet fuel consumption in 2014, allowing the current certificated 50% blend with conventional fuel. The major biomass hotspots are close to airport and fuel logistic basis. However, even with a US$ 200.tCO -1 2 tax, hydroprocessed esters and fatty acids (HEFA) biojet is far from being competitive with petroleum-based jet fuel, whereas the Fischer-Tropsch synthetic paraffinic kerosene (FT-SPK) route may produce a competitive biojet. One possible pathway to incentivize biojet fuel production in Brazil would be, first, to implement carbon taxes that would allow the development of smaller plants. Then, with technological learning and larger production scales, it would be possible to reduce or even eliminate the carbon taxes.
