In short, it has enabled the UK Government to completely phase out truly unsustainable biofuels, like those made from monoculture palm oil, while bringing forward the really good biofuels, such as wheat bioethanol and biodiesel from used cooking oil UCO. The Vivergo and Ensus plants in the North East are good examples, producing over million litres of wheat bioethanol and over , tonnes of animal feed per year, with greenhouse gas savings equivalent to taking , cars off the road. Along with other renewables, biofuels are helping regions like Humberside and the North East become engines of British industry once again, reawakening the exceptional science and engineering expertise which is part of the heritage of these regions.
So many of my predictions have been correct. Biofuel targets driving global hunger crisis. The great biofuels scandal. Biofuels are helping our agriculture too. These products help reduce dependence on animal feed imports from overseas, where environmental regulations are often weaker than in the UK. The obligation to demonstrate sustainable crop-sourcing for the biofuels market means that farmers who send crops for both food and fuel production have to raise their environmental standards to remain competitive.
What ILUC is really about is the anticipated emissions of the food industry bringing more land into cultivation as crops from existing farmland are diverted to biofuels. While it is true that demand for biofuels is changing the dynamics of internationally traded commodities, it is unfair to demonise bio-based energy, which helps fight climate change, while food, cosmetics and textile applications are somehow considered "natural".
Ecofys and the World Bank have both shown that crude oil prices, stock-to-use ratios and exchange rate movements are the principal causes of higher food prices — not demand for biofuels. The question is: how do we use our natural bio-based resources most efficiently to meet the interlinked challenges of climate change, population growth and energy and food security? The answer is not to simply force the newest entrant out of the market by making the biofuels industry pay for the emissions of the food industry, but to ensure that all crop-based industries — from food to textiles to cosmetics — are held to the same high environmental standards as the EU biofuels industry.
Sustainable biofuels produce food and fuel while raising environmental standards and arable productivity in farming around the world. They bring growth and industry back to the UK and support our agriculture.

Abstract Bioethanol is one of the most important alternative renewable energy sources that substitute the fossil fuels. Method overview Energy consumption has increased steadily over the last century as the world population has grown and more countries have become industrialized. Methodological protocols Material The sugarcane bagasse was collected from sugar industry and cleans it by distilled water to remove impurity.
Steam pretreatment Pretreatment is one of significant step for maximum conversion of ethanol, Fig. Acid hydrolysis In acid hydrolysis cellulose and hemicellulose of biomass were converted into glucose. Fermentation The supernatant from dilute acid hydrolysis of lignocelluloses can contain both six-carbon hexoses and five-carbon pentoses sugars if both cellulose and hemicellulose are hydrolyzed. Distillation A distillation system was used to separates the bioethanol from water in the liquid mixture.
Experimental design and data analysis The central composite design CCD was employed to fit a second-order polynomial model and to obtain an experimental error. Table 1 Minimum and maximum value of parameters. Table 2 Numeric values of parameters in hydrolysis according to factorial design.
Determination of ethanol concentration The ethanol concentration was determined by gas chromatography.
Method validation Fitting of second-order polynomial equation The RSM have several classes of designs, with their own properties and characteristics. Effect of temperature and time The effect of temperature and time is represented in Fig. Effect of acid concentration and time The effect of acid concentration and time is represented in Fig. Effect of temperature and acid concentration The effect of temperature and acid concentration is shown in Fig.
Optimization of hydrolysis parameters The optimization of hydrolysis criteria for ethanol production from SCB using dilute acid treatment are summarized in Table 3. Characterization of bagasse The chemical analysis of sugarcane bagasse done for determination of cellulose, hemicellulose lignin ash and other composition which mention in Table 4.
Table 4 Optimization criteria for optimum yield of ethanol. No Components Weight percentage 1 Total organic matter Outcomes The outcome of this research methodology is that sugarcane bagasse is promising lignocellulosic feedstock for bioethanol production.
