What are biofuels
If we’re talking about liquid fuels for transport they’ll essentially be split into two forms: Biodiesel and Bioethanol.
Biodiesel can be used as a mix with petroleum derived diesel or as a one hundred% fuel. It contains better amounts of oxygen and thus burns extra efficiently, has higher lubricity and decreased polyols/toxic emissions. In its pure kind it has a decrease Cetane worth (a measure of the combustible worth of the diesel fuel) than petroleum based fuels but this can be simply improved by the small addition of terpene hydrocarbons which doesn’t add any toxicity.
Bioethanol can be used as a mix up to 85% with regular unleaded petrol. Restrictions, so far, primarily centre round warranties from engine manufacturers, although many now allow unrestricted use of biodiesel and manufacturers are producing petrol kind engines specifically designed to run on 85% blends of bioethanol. The best on-going downside with bioethanol is the fact that being hydrophilic it has been discovered to be to fairly corrosive to certain alloy inside elements of the engine. Engine manufacturers at the moment are beginning to have second thoughts about approving its use even at malim petroleum & machinery sdn bhd director a ten% addition stage. It’s not an insurmountable downside and will be overcome by the addition of dimer or dicarboxylic acids derived from timber and used is an anticorrosive. The query, as always, is one of price.
How are they produced
Biodiesel could be manufactured from any vegetable or animal (incl. fish) oil. As well as unrestricted amounts of reclaimed oils may be added to the process (used frying oils, rolling oils, slicing oils, leather tanning oils etc.) The process is just not reliant on the product being prime, it generally is a by-product from the edible oil refining trade, industrial vegetable/animal oil refining trade or just waste recovery. It may even be extracted from used coffee grounds (forty% oil), of which thousands of tonnes every year go both to landfill or animal feed.
The method yields a precious by-product within the form of 80-eighty five% purity crude Glycerine which is either utilized in its crude kind or further refined to be used in hundreds of other products.
Bioethanol is an alcohol and is the most generally used biofuel on this planet as we speak. Starch crops (wheat, corn, sugar cane and beet and cellulose derived from waste forestry and agricultural products.) In a brewing course of the starch is converted to sugars, which ferment into ethanol (ethyl alcohol). Strictly speaking only the ethanol made from cellulose should be referred to as bioethanol and I am certain this point will likely be argued by HM Customs.
What are the advantages
Biodiesel is essentially a fatty acid alkyl ester in which the unique oil must bear a process referred to as transesterification (more commonly generally known as simply esterification) where the oils are reacted with an alcohol (ethanol or methanol (methyl alcohol or wooden alcohol)) to form a fatty ester which may then be used as a blend or a straight gasoline. Biodiesel contributes little to the environment within the form of pollution, every tonnes of biodiesel burned saves 3 times its personal weight in CO2 from getting into the ambiance. If we additionally perceive that rising the oilseed crop in the first place additionally consumes CO2 and gives oxygen, it has a double profit. Once burned its particulate emissions are now not carcinogenic, unlike diesel derived from petroleum. From the engines viewpoint it supplies more oxygen, permitting a cleaner burn and significantly improved lubricity.
Bioethanol has all of the above advantages and likewise improves the octane value of the petrol/bioethanol blend, but, as talked about, is now a corrosive downside.
Extra recently work has been quite successful in extracting oil from algae.
In addition since 2004 a renewable liquid gas derived from the by-products of the timber industry has been imported into the UK to substitute heavy gas oil in power generations. That is now the oil fuel of alternative in combind oil/coal energy stations and is getting used to allow old coal fired stations to burn a renewable oil along with wood chip which reduces its toxic output to virtually zero.
Why is the UK the only nation with no sustainable transport fuels coverage
The reply is kind of easy – the use of transport fuels within the UK is governed by the 1979 Hydrocarbons Act, which refers only to “mineral oils”. In an effort to comply with directive ninety two/eighty one, HM Treasury widened the scope of the Finance Act 1993 (part 10) to “mineral gas substitutes” and this was utilized by HMC on 1st December 1995.
Nevertheless, Directive 92/81 also states – that member states can cut back the charges within their own territories for pilot projects, significantly for fuels from renewable sources.
Germany, France, Italy, Belgium, Austria, Sweden and Norway have all taken benefit of subsequent EEC legislation which permits a “pilot quantity” of 5 million mt to be produced.
On November 8th 2000 the Chancellor invited industry to develop “environmentally friendly” different highway fuels and that he would make main reductions in duty charges in the budget of 2001. A full report of this can be read on BABFO web site. The top outcome was a pathetic 20p per litre cut in responsibility which left biodiesel with 25p per litre responsibility, making it significantly costlier than the hydrocarbon derived product. A lot of the blame for this was due to misleading info from DEFRA who stated “that a rise in oilseed rape may battle with Authorities targets to reduce the decline in farmland birds”. This was immediately opposite to statements from RSPB who suggested that given the suitable management more rape may profit chook populations and reduce greenhouse emissions.
Different EU nations have reduce responsibility rates to zero in recognition of the worth of this fuel and newest (2008) figures are as follows:
Figures are expressed in thousands and thousands of litres per yr.
France: ………………991………………………………. 578
Germany: …………..3180 ………………………………730
Austria: ……………….252 ……………………………..<100
Italy: ……………………n/a ………………………………..n/a
USA: …………………2650 ………………………………36300
Holland: ……………..1372 ………………………………..n/a
Spain:………………… 926 …………………………………578
United Kingdom: …..347 …………………………………153
Canada:……………… 100 …………………………………870
Other than the inflexibility of HM Customs to embrace new “green” know-how, one reason might be that none of the international locations mentioned above (besides USA, Canada and UK) are hydrocarbon oil producers. Because the bottom worth of the vegetable oil is higher than that for crude hydrocarbon oil and since the pump costs must be the same, for each varieties, the Chancellor will obtain considerably much less revenue from gasoline tax. We should therefore draw the conclusion that, once more, revenue is taken into account much more necessary than, emissions, well being, international warming or diminishing stocks of fossil fuels.
That is a vast topic with many implications, not least the prosperity of our agricultural industry and future national health.
Very small scale utilization.
Should you run a diesel powered automobile or truck (the older the better) you may put used cooking oil instantly into the tank. All that needs to be performed is to filter any meals particles from the oil and, preferably add to some existing mineral diesel within the tank. Moreover this ought to be executed during the summer season when the night temperature doesn’t drop too low otherwise the vegetable oil might thicken. During the winter the veg oil must be added at the rate of 1 gallon to three gallons of mineral oil.
For these of you who are mechanically minded you may run on pure veg oil all 12 months spherical by looking for out a gas pump from an older Peugeot in a scrap yard (guarantee it’s the version that preheats the gasoline)
A work colleague of mine used to go to the local Sainsbury supermarket when they had a promotion on veg oil and purchase several 3 litre malim petroleum & machinery sdn bhd director containers of the cheapest veg oil available which he poured straight into his diesel Land-Rover Discovery. It labored absolutely wonderful with only a gentle scent of cooking doughnuts.
Motor manufacturers will disagree with this and i settle for no duty (whilst I do know it really works advantageous). I’d counsel you begin small with just a litre or so to half a tank of mineral diesel. If the engine coughs or misses (which I doubt very much) then discontinue as some delicate excessive efficiency diesel engines could protest. I take advantage of it in my trendy common rail turbo-charged diesel Land-Rover with no problems at all. Being within the chemical business I sometimes add a litre or so of d’limonene, dipentene or turpentine which acts as a centane enhancer and removes any gum construct-up.
Farmers – With out them the place would all our meals come from
Farming today is driven by the requirements of politics not the needs of the patron. The contribution of the farmer is crucial to our very existence. With out them we’d starve, grow to be in poor health and reside in deprivation .

I am not sure how diesel gasoline derived from vegetable stands as opposed to mineral fuel. Vegetable gas is such low toxicity that petrol is a far better pollutant (in my view even higher than mineral diesel) However, there are some political issues creeping in right here, perhaps backed by the motor and gas manufacturers. Personally, I would like to put up with a number of particulates than the very toxic benzene fumes from petrol. There isn’t a excuse for the large clouds of smoke from buses and the like which can simply be cured by setting the injectors appropriately and proper upkeep.

Thank you JSChams
I notice it needs a little bit tidying up because it did not switch correctly.
Kind regards Peter
