Potential for Large Scale Ethanol Production Recent legislation by the Congress of the United States has created a mandate for 5 billion gallons of renewable fuel (notably ethanol) to be consumed annually by 2015. In light of this recent push for alternative fuels, many different biomass solutions have been considered to meet the energy need for the 200 million cars on the road. While the most efficient bio-fuels are derived from palm oil and sugarcane, the Unites States has begun to focus on the more regional corn crops to produce new renewable fuels. This program appears to have great potential towards achieving a sustainable future devoid of foreign oil dependence, until the economic implications of large-scale ethanol production are considered. With that said, it’s important for the United States Government to understand the relative inefficiency, environmental, and social cost of large-scale ethanol production in the US. Ethanol is a fuel grade form of alcohol that is produced from grain fermentation to create a clean, burnable oil alternative (Heinberg, 171). On a small scale, ethanol production appears to be a practical form of energy for farmers, but is limited by its lack of production facilities and unfavorable energy returned on energy invested. Ethanol has an extremely variable EROEI according to several net energy analyses. Cornell professor David Pimentel found a 29% net loss of energy after conducting two independent tests. Both studies found that, “the fuel cost more energy to produce than it eventually delivered to society.” (Heinberg, 173) While this study painted a negative picture for ethanol production, a USDA researcher recognized as much as a 77% energy profit; although, a ... ... middle of paper ... ... farmers needs.

and machinery is imported from Japan for both refining and manufacturing. The plant is well maintained and it’s production capacity is increased gradually. Mehran sugar mill has continuously grown since its origin and come out as a diversified leading company. Mehran Sugar mill is Pakistan’s leading producer and marketer in white and brown sugar. Further it has investments in ethanol facility and blue chip companies which are listed on the Karachi Stock Exchange. Mehran sugar mill has been awarded
make use of biofuel, solar, and geothermal resources (Brown et al. 2008, 27). The focus of this paper will concentrate on three alternative energy solutions: 1. Biofuels, 2. Solar Power, and 3. Geothermal. Biofuels will be broken down into biomass, ethanol and biodiesel. Solar energy will be divided into solar power plants, residential solar and passive solar systems. Geothermal energy is constituted of geothermal power plants, geothermal water heating and heat pumps. How biofuels could reduce Hawaii’s
processed products, including fluid milk, cream, butter and fermented dairy products like cheese and yogurt. Relative to other food sectors, dairy industries produce substantial environmental footprints at all steps of the value chain, from the production of feed for dairy cows to the distribution of milk and milk products. For instance, cheese is associated with a greenhouse gas emission of 5.9kg CO2 equivalents/kg, compared to 0.17kg CO2 equivalents/kg for peanut butter. However, the dairy industries
Global sugar production is around 176.36 million tons, every year. 80% of this global sugar production is produced from sugarcane and grown largely in tropical countries. The remaining 20% is produced from sugar beet, which is grown mostly in the temperate zones of the northern hemisphere. About 70 countries produce sugar from sugar cane, 40 countries from sugar beet and 10 countries from both. The top 10 largest sugar producing nations represent roughly 75% of world sugar production. India is one
to traditional forms of energy Even though production of biofuels, such as ethanol and biodiesel, is rapidly increasing, their contribution to total fuel consumption will remain limited. Biofuels are sources of energy produced directly or indirectly from organic material including animal waste and plant material. In order to be considered a biofuel, at least 80% of the fuel must be made from renewable materials. There are 3 main types of biofuels: ethanol, biodiesel and biojet fuel. Biofuels are considered
Although these resources are abundant, they will not always be readily available to us. That is why we need to begin searching for other renewable resources that can create more energy. Biomass is a very important renewable resource and has the potential to be our gateway to a cleaner future. What is Biomass? According to Conserve Energy Future, biomass is energy contained within plants and animals. This includes organic matter from plants, animals, and other waste products from organic sources.
yield is 1kg from 10L of milk, where the balance (9L) is whey. Hence, it is apparent that daily production of whey can amount up to several millions of litres in large cheese plants. The world whey production is over 160 million tons per year (estimated as 9-fold of the cheese production), showing a 1–2% annual growth rate (Guimaraes et al., 2010). Today, the annual global increase of whey production is equivalent to 2%, which
The most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gas
supporting industries explains that when local industries compete against one another, this spurs the emergence of cost effective and innovative inputs. This very well indicates that in the future biofuel demand will lead to more innovative, cheaper production. The last factor, firm strategy, structure, and rivalry states that over the long run more local rivalry is better since it puts pressure on firms to innovate and improve. In addition to the diamond model, the Leontief Paradox has proven that
many other countries, including Ethiopia. Sugar cane has been 1.71 billion tones cane production and 71.7 tones/ha yield in 23.9 million hectares in the World; 89.594 million tones cane production and 56.81 tones/ha yield in 1.577 million hectares in Africa and also 2.4 million tone cane production and 126.9 tones/ha yield in 19000 hectares in Ethiopia (FAOSTA, 2012). In Ethiopia average annual sugar production is 300, 000 tons which covers only 60% country`s domestic consumption, the difference
Midwest Ag Processing (MAP) is a small corn and soybean processor located in Southeastern Iowa. They provide high quality fructose corn syrup, corn starch, and soybean oils that large processing plants are unable to offer. Currently, issues with meeting shipment deadlines have been emerging. Shipments have been arriving to the customer days after the due date. This is happening because there is an increase in truck and rail congestion for biofuels. Causing transportation costs to rise, this
and they are not a renewable source of fuel. Thus it is important that we find another alternative source of fuel. The growth of Algae Oil is a recognised process due to its final products and the production of oil is a function of the selection and feeding of a specific strain of algae. The production of Algae Oil is primarily used in the process of producing biodiesel fuel. All Biofuels are made from biomass. These biofuels can all be produced from algae. Microalgae contains oil within its cell
Soil forms part of a complete ecosystem as it is a habitat for certain organisms hence its importance cannot be overemphasized. Marginal land can be referred to as low quality land that has low agricultural value. Most crops that are used for the production of biofuels are grown on marginal lands since they require less nutrients, this prevents the use of land that have good soil quality (Lian and Ghazoul, 2008). Farmers allow nutrient rich portions of the plant to decompose into the soil this helps
high ratio of yield to area required for growth. In 1960 Oswald and Golweke proposed the use of large‐scale ponds for cultivating algae on wastewater nutrients and anaerobically fermenting the biomass into methane fuel. Algae, like all bio fuels, harvests the energy from water and sunlight to produce oil which can be converted into biodiesel as well as the carbohydrate content to be fermented into ethanol (Benemann, Olst, et al. 1). The concept of using vegetal oil as an engine fuel likely dates back
to be a source of probiotic bacteria. Other potential attributes of kimchi include, lowering cholesterol, improvement of immune function, protection against oxidative and antineoplastic activity. Koreans consume kimchi in a daily basis at virtually every meal, usually as a side dish; nevertheless it can also be utilized in the compositions of other dishes, such as soups and pancakes. Although kimchi production is usually a homemade process, the large scale manufacturing is expanding at a fast pace
