Sustainability and Environmental Impacts of Sugarcane Biofuels

Abstract Ethanol produced from lignocelluloses is expected to make a major contribution on transportation fuel markets. In this paper, a life cycle assessment was carried out to assess the environmental burdens of ethanol production from wheat straw and its use as ethanol blend fuels. The production of ethanol can impact the environment both positively and negatively, depending on the production method used. Ethanol is typically produced through the fermentation of sugars by yeast, or through the hydration of ethene from petroleum. In this way, ethanol and other renewables simply recycle atmospheric carbon. Even when the energy use and emissions related to the full production process

There is a trend of reduction of environmental impacts over time, reflecting the environmental advantages due to advances on the learning curve of second-generation ethanol technology and on biomass production system. Sustainable or not? Early proponents of ethanol believed it would have a lower environmental impact than gasoline. But already in 2013, emerging research was raising concerns that increased ethanol production was increasing carbon emissions due to the cultivation of previously conserved land. The main reason for the reduction in environmental impacts is that the renewable power production shows much lower impacts than the coal based Chinese electricity mix.

Hence, to identify the environmental burdens of the bioethanol production system, a comprehensive evaluation is required. Life cycle assessment, defined according to ISO14040 and 14044 [9, 10], is mainly used to identify and measure the environmental impact towards sustainability [11]. We evaluate the fast-expanding food–energy system of double-cropped maize ethanol in the Central-West region of Brazil with respect to SDG impacts, combining life-cycle environmental and

For lignocellulosic ethanol produced from corn stover and switchgrass, a positive net energy value and reduced GHG emissions are seen when compared to gasoline. In addition to net energy results and system GHG emissions, the petroleum displacement and land use impacts for an expanding and evolving ethanol industry are also evaluated. World Resource Institute, 1990). These ecosystem and environmental implications of corn ethanol production largely have been ignored until very recently, but increased concern over global warming, sea rise, and potential threats to life on planet earth (Hansen, 2006), bring the environmental challenges more into focus.

Life Cycle Assessment of Bioethanol Production: A Review of

The Renewable Fuel Standard (RFS) specifies the use of biofuels in the United States and thereby guides nearly half of all global biofuel production, yet outcomes of this keystone climate and environmental regulation remain unclear. Here we combine econometric analyses, land use observations, and biophysical models to estimate the realized effects of the The Drawbacks of Ethanol Fuel Different Environmental Impact Though ethanol and other biofuels are often promoted as clean, low-cost alternatives to gasoline, industrial corn and soy farming still For the long-term adoption and success of the EBP, the following critical areas must be analyzed: integrated ethanol production from multiple feedstocks, demand and linkage to industries requiring ethanol, impact on the environment and revenue prospects, and evaluation of the policy measures adopted.

There is a trend of reduction of environmental impacts over time, reflecting the environmental advantages due to advances on the learning curve of second-generation ethanol technology and on biomass production system. However, the environmental impact and energy efficiency of nopal farming and ethanol production in plant-wide biorefineries are unknown. Inorganic production and the classic biorefinery cause undesirable environmental impacts that could be

In general, mechanized scenarios were associated with lower ethanol production costs and higher internal rates of return due to lower biomass production cost, higher ethanol yield, and higher electricity surplus. This paper aims to develop a life-cycle assessment (LCA) for sugarcane fuel ethanol, assess its environmental impact potential, and identify Additionally, ethanol blends can increase evaporative emissions in vehicles, contributing to the formation of ground-level ozone and smog. While the overall impact of ethanol on the climate remains uncertain, it is clear that it has

Environmental impact and energy balance assessment in ethanol production from sugarcane molasses: A life cycle analysis in southern India However, a sensitivity analysis conducted by expanding the ethanol system boundary to include the consequential effects of removing wheat straw from the field, suggested an increase in the overall environmental burdens of ethanol life cycles but certain wheat straw ethanol pathway (i.e. with steam explosion pretreatment) still remain

As the demand for renewable fuels continues to grow, it is important to evaluate the environmental impact of ethanol production using life cycle assessment (LCA). To address the high fossil energy dependency and the low-value utilization of stillage (WDGS) in conventional cassava-based ethanol production—factors that increase greenhouse gas emissions and limit overall sustainability—this study develops an integrated ethanol–biogas–CHP system that valorizes stillage and enhances energy recovery.

The policy expands the scope of raw materials for ethanol production by allowing sugarcane juice. Other sources of ethanol production are bagasse, sugar, molasses, sugar beet, sweet sorghum, corn, cassava, rotten potatoes, damaged foodgrains, surplus biomass, agricultural waste, algae, grasses, twigs, sawdust and forestry waste (Das

In fact, the study found that corn ethanol “has failed to meet the [RFS’s] own greenhouse gas emissions targets and negatively affected water quality, the area of land used for conservation, and other ecosystem processes.” But we know that ethanol’s environmental impact is even worse than this study suggests.

Ethanol production from MSW is a novel strategy that has been proposed and researched for practical use; however, MSW ethanol plants are not widely applied in practice. Thus, this study has been conducted to analyze and compare the environmental and economic performance of incineration and ethanol production as alternatives to landfilling MSW. Brewing process involves the production of a large amount of lignocellulosic residues such as barley straw from cereal cultivation and brewer’s spent grains. This study was aimed at developing a full-scale biorefinery system for generating bio-ethanol and xylooligosaccharides (XOS) considering the mentioned residues as feedstock.

According to (Ocampo Batlle et al., 2020), the integration of sugarcane and palm oil crops could increase the energy portfolio, improve performance, and thus, mitigate the environmental impact of biodiesel production systems of palm oil and sugarcane ethanol. The results of the Life Cycle Impact Assessment (LCIA) indicated that the highest impact in all the categories is from the production of bioethanol from first-generation feedstock, corn. A significant portion of this impact was found to be contributed by the field operations (feedstock cultivation and acquisition).

Ethanol produced from BOF gas at the Chinese site performs significantly better than ethanol from the regular market for most relevant environmental impacts: particulate matter (-34 %), acidification (-52%), human toxicity carcinogenic (-92 %) and land use (-93 %). Economic and environmental impacts of ethanol biorefineries with different sugarcane (Saccharum spp.) production technologies are evaluated with a focus on harvesting systems, reduced tillage Purpose The use of bagasse and trash from sugarcane fields in ethanol production is supposed to increase the ethanol yield per hectare, to reduce the energy demand, greenhouse gas emissions, and other environmental impacts. In this article, different technological options of ethanol production are investigated and quantified looking at potential environmental impacts.
