Likewise, conversion of dehydrated ethanol to biogasoline surely takes some extra energy, dropping energy efficiency still further. Finally, in small fractions, ethanol can be mixed easily with gasoline without any deleterious effect for the engine and even benefiting the environment. Biogasoline or biopetrol (British English) is a type of gasoline produced from biomass such as algae. Like traditionally produced gasoline, it is made up of hydrocarbons with 6 ( hexane ) to 12 ( dodecane ) carbon atoms per molecule and can be used in internal-combustion engines . Biogasoline (gasohol or E10 blend) is an ethanol-gasoline blend with 10 v/v % of ethanol. Ethanol is being produced by fermentation of sugarcane, maize, wheat or cassava crops.

The environmental impact categories presented in this paper are the ones commonly included in environmental product declarations (EPDs): Potential impact on global warming, stratospheric ozone depletion, photochemical oxidant formation, acidiﬁcation potential, and eutrophication potential.

Scientists are using information from NASA’s Earth-observing satellites, on-the-ground sensors and computer-based datasets to study the environmental, economic and societal impacts of the COVID-19 pandemic. We’re facing up to the future, doing more for our clothes, our suppliers, their communities and our impact on environment. We’ve looked hard both inside and outside our business, and come up with a plan that will help us be ready for the future.
in the planning phase and when environmental permits for biogas plants are awarded. Moreover, the project will promote the sustainable and safe utilisation of nutrient-rich digestates, created in biogas production, as recycled fertilizers. With regard to the EEG’s aim of preventing or reducing the negative effects on the environment as much as possible by promoting the use of biogas for the sustainable generation of energy, the use of green cuttings and agricultural and forestry waste is also essential.

Introduction The world is presently confronted with the twin crises of fossil fuel depletion and environmental degradation. Argonne researchers show that compared to gasoline, biofuel from energy crops can reduce emissions by 101 to 115 percent.

However, in comparison Biofuel feedstocks include many non-GHG environmental impacts, Feb 11, 2019 Biofuels are considered an important solution to climate change, yet research has shown that many biofuels may actually emit more greenhouse Jun 29, 2019 In this chapter, the environmental, social, and economic impacts of bioethanol produced from sugarcane are discussed in the context of May 8, 2019 Analyses of a fuel supply chain enable evaluation of the cumulative environmental impacts resulting from all steps (e.g., the impact of feedstock Biogas plants significantly curb the greenhouse effect: the plants lower methane emissions by capturing this harmful gas and using it as fuel.
