What is the difference between Biomass Biofuel and Biogas?
Biomass is the combination of animal waste or dung, crop wastes or agricultural waste. While biofuel is the fuel or energy produced by using crop waste, the product is ethanol which is used as a fuel.
Biogas is methane which is produced by fermentation of animal dung in the fermenter or biogas plant.
What is a good prize for a school game?
Water guns, slinkies, sillybandz, stuffed animal, earphones, paint kit, candy
IT DEPENDS ON WHAT THE PRIZE IS FOR
A bio-oil is any form of automotive oil which is synthesized, as opposed to petroleum-based.
Can banana peelings be an alternative source of biofuel?
Try studying it and observing it, Conduct a study on it, like what I did to Pine Tree branches, I found out biofuel in it :)
Where and how can you obtain biodiesel fuel?
See the related link to the National Biodiesel Board's - Retailer Map.
Look there for a retailer in your state.
When shopping for biodiesel, however, make sure that they sell biodiesel that conforms to the most recent ASTM standard.
Can you use biodiesel on your John Deere 4850?
B5 or 5% biodiesel would be the limit I would use in any tractor at least at the current level of biodiesel formulations. In the winter biodiesel does cause more problems so be more careful.
Can fruits be a new source of fuel?
The best biofuels are those made from fast-growing plants that can be used in their entirety and quickly replaced.
Fruit, being the end product of a plant, is extremely energy-intensive. That means that a great deal more energy went into producing it than could possible be stored in it. One can certainly make fuel from fruit, but it would be highly inefficient.
Is it ok to use non trans fat waste oil to produce biodiesel?
Yes you can use all trans fat oils to make biodiesel
How is Bio fuel better than fossil fuel?
Biofuel is made from plants which are Renewable Resources, so it can basically be restored if it ever runs low. Fossil Fuels on the other hand take millions of years to form, and is Non-Renewable. Also, Biofuel is more Earth-friendly.
Would it harm a bio diesel engine if you used regular diesel?
Most readily available bio-diesels are about 90% diesel and 10% vegetable oil. So no, wont hurt.
How is bio fuel made and what is made from?
bio fuel consist of waste bio degradable material like paper, vegetables, cow dung, leaves, eatables, these things are decomposed in a container which leads to formation of gases that can be used as bio fuel .
The fuels that we are using at the moment is not renewable therefore, we will run out so when we do run out, our ozone layer will be damaged out of our control and we would not have any fuels left. Bio fuel is important because if we use it, then we will be damaging our ozone layer even less and there will be lots more fuel out of the dead crops that we can all use.
What are the problems created by using ethanol as a biofuel?
Since ethanol has chiefly been made from corn, this will remove corn from sale from other uses and could drive up prices. Corn requires land to grow which might be used for other crops and generally requires fertilizers because it can deplete the soil of nutrients.
Some farmers have managed to rotate corn and soybeans to allow continuous production, but this only provides half of the potential corn production for a given acreage.
Other processes have shown some promise to use lower-grade agricultural residues to create methanol or butanol, which have improved energy content.
Why kerosene you can mix with petrol and diesel?
If we dissolve kerosene in petrol running vehicle the petrol filtrer in the car will be damaged and also the pump.
How much does it cost to complete an engine conversion from gas to biofuel?
You will need to install a special fuel conversion kit, or let a professional install it. The kit will cost you a lot of money, and most kits will cost more than $2000.
Yes, but since biofuel is a substitute for diesel its only used in diesel burning cars.
They can be from a variety of naturally occurring substances. Most commercial biofuels are manufactured from grain plants. But things such as adipose tissue could make biofuel, as well. In Sweden, some several thousand dead rabbits were supposed to be converted into biofuel, for example.
Best way to dispose glycerin from bio diesel fuel?
What is left over from the extracting the gas out is bio-glycerin or bio-glycerol. Bio-glycerin is the major bi-product obtained after producing Bio-diesel. Bio-glycerin in its crude form has a many uses, starting from manufacturing soaps to various cosmetic products. Glycerin is one of the most important bi-products of bio-diesel. Now making use of it will reduce the actual cost of bio-diesel produced in any given unit. The glycerin in crude form can be used to make soap, degreaser, cosmetics, lotions, candles, etc….

What is a problem that is created by ethanol as a biofuel?
Growing corn can be bad for the soil (APEX)
biomass burning is perceived as being a sensible form of energy generation. ... So the potential is there for a substantial fraction of our energy budget to come from biomass burning.
What are the disadvantages of biofuels?
- The disadvantage of biofuels is that despite being a renewable source of energy the levels of power/energy it produces are not high enough (compared to fossil fuels) to be used commerically i.e. for industry, power stations etc.
- Despite the many positive characteristics of biofuels, there are also many disadvantages to these energy sources. The main issue is producing biofuels in a sustainable way. This means an emphasis on agricultural practices that do not use rainforests / other endangered habitats or food crop producing land or extensive irrigation or fertilization. Some Biofuels are more harmful than others.
Rainforest and natural habitat destruction:
- Palm oil can be especially damaging but is cheaper than other alternatives. Most palm oil is produced on destroyed rainforest habitat.) Unilever is the world's biggest purchaser of palm oil. The Center for Orangutan Protection concluded orangutans there could be extinct in Borneo by 2011.
Greenhouse gas reduction:
- Rapeseed may produce more CO2 than fossil fuels - (link below).
- Shell is working to develop the fuel ethanol from wheat straw to reduce waste and emissions - (link below).
- It takes 840 years for a palm oil plantation to soak up the carbon emitted when rainforest is burnt to plant the crop.
- Modern agriculture uses a lot of farm machinery and a lot of petroleum-based fuel to run that machinery, so that the fuel invested to create biofuel can offset any possible savings from using biofuel as a substitute for petroleum-based fuels.
- Several studies have been conducted to analyze the carbon footprint of biofuels, and while they may be cleaner to burn, there are strong indications that the process to produce the fuel - including the machinery necessary to cultivate the crops and the plants to produce the fuel - has hefty carbon emissions.
- Biofuels have a lower energy output than traditional fuels and therefore require greater quantities to be consumed in order to produce the same energy level.
Affect on existing agriculture and water supplies:
- Biofuel production can adversely affect food and water supplies to poorer communities and income from agriculture for those communities. It can contribute to deforestation and soil erosion.
- Also, because land ownership is so important to survival, human rights are often very sensitive to any change in land use.
- As demand for food crops such as corn grows it could also raise prices for necessary staple food crops. Malaysia & Indonesia currently meet about 87% of global palm oil demand. China is currently the world's largest importer of palm oil, accounting for one third of all global trade. Biofuel is made from things such as corn, which may be more needed in the form of food than they are as fuel.
they are more labour intensive and take longer to make . they are also less popular.
well biofuels are great because they use less fossil fuels. but the problem is that they cause food prices to go up, which will affect us and the the poorest countries in the world, especially those people that already cant afford food. in my own experiance, they caused my millage to be way lower then usual, i went from 22 mpg in my truck to about 12 or 13, maybe in the future they will fix these problems, but for now i dont support biofuels, we would be trading one problem for another.
You can by cars made for biofuels. The Saab 9-3 is avalible with an E85 model (for not much more) that uses 85% ethonal. This means the car is cheaper to run, uses less fossil fuel and also runs better. E85, however had limited avalibility. For example it is avalible in the UK but only at a few places in Australia. So if you live in Europe it could be worth it, these cars can run on regular petrol too.
Limited in the quantity of electricity it can produce on the global scale.
There is little or no control on the rate of gas production, although the gas can, to some extent be stored and used as required.
There are other factors as well. Check the Wikipedia page on Issues relating to biofuels for more details.
The two biggest obstacles to bio-fuel are:
1. It take up space - the amount of space required to produce 1 barrel of biodiesel from vegetable (soy bean) oil is 2/3rds of an acre. It would take therefore 880,000 acres to produce in one year the amount of oil produced by drilling, in the state of Texas, in one day. or more succinctly it would take an area twice the size of Texas to replace the oil produced there.
2. It is costly: It costs $2.80 per gallon to produce 1 gallon of bio-diesel. It costs $0.75 per gallon to produce diesel from petroleum.
** statistics for corn oil are higher, and for rapeseed oil are slightly lower.
A third disadvantage would be soil depletion, growing a single crop on a given property depletes essential nutrients for that crop.
That being said, biodiesel produced as a part of a more diversified renewable energy plan is not a bad idea.
Plants used for biofuels could be used for food.
What is biofuel combined with regular gasoline called?
Ethanol,a type of alcohol is produced mostly from corn,but other organic substances can also be used.
