About bio-fuels:

 

What is a bio-fuel?   It is any substitute fuel made from renewable, non-fossil, organic materials. Using bio-fuels will not add new carbon to the atmosphere.  Fossil fuels and mineral chemicals are not bio-fuels, and burning them adds carbon to the atmosphere that has been safely captured beneath the earth's surface for millions of years.  This additional carbon as carbon dioxide in the atmosphere is the main cause of Global Warming and Climate Change. 

 

Why should I use bio-fuels?

Every time you burn mineral diesel you contribute to global warming, and add toxic wastes to the environment. By changing to a bio-fuel you will help to reduce the increase in atmospheric carbon-dioxide levels, and you will not be adding any toxic materials or heavy metals to the environment.  In our view the most beneficial form of bio-fuel is Bio-power MUVO.

 

The production of bio-fuels will take land away from growing food that is needed to feed those in poorer nations
Certainly the rush by many big companies to get into the emerging new sector of bio-fuel production is being criticised by many environmental groups because of the damage being done to prepare land for palm oil production.  Large areas of tropical rainforest in East Asia and Africa have been felled to provide new palm oil plantations.  Once land is used to grow palm oil it is very difficult to revert back to other forms of agriculture or to revert to tropical rainforest.  However, the major component of bio-power fuels is used oil that we collect form pubs, restaurants and canteens close to the area where we process the oil to make fuel, which is then sold locally to meet local needs.  We do not import vegetable oil for fuel making, and we do not ship large quantities of vegetable oil around the globe.  We try to find sustainable methods where ever we can.

 

What is the difference between BIO-DIESEL, Straight Vegetable Oil (SVO) and Modified Used Vegetable Oil (MUVO)?

    Bio-diesel is specifically Fatty Acid Methyl Ester (FAME), made by the transesterification of lipid fats.  This is a chemical process using methanol and caustic soda that shatters the lipid fat molecules to produce FAME and also waste Glycerol as a by-product.  We no longer use this method because we regard it as a wasteful and inefficient way to make bio-fuels.

 

    Straight Vegetable Oil (SVO) is any virgin (unused) vegetable oil (normally rape seed oil or corn oil) used as a fuel without modification.  Environmentally, it is the most efficient way to use bio-fuel, but it normally requires changes to the engine or the fuel delivery system.  Using food grade vegetable oil is not a responsible way to power your car, because food grade oil is highly selected and then processed specifically to be used as a food.  If this materials is used as a fuel then this simply puts up the prices of vegetable oil, and this can take the material out of economic reach for people in poorer areas of the world.

 

    Waste Vegetable Oil (WVO) is used vegetable oil as collected from pubs, restaurants and chip shops, which is the principle ingredient for our fuel.  This is the best way to power your car if you are prepared to fit the necessary equipment.

 

    Modified Used Vegetable oil (MUVO) is a special form of bio-fuel, developed by John Nicholson, founder of bio-power.   It is made from waste vegetable fat, which has been cleaned and specially treated with added organic oils and solvents so that it can be used in normal diesel engines, without significant modification.

 

Can I burn bio-fuels in any normal diesel engine?
YES, nearly all compression ignition engines will burn BIO-DIESEL without any modification.  However, rubber parts in the fuel delivery system may dissolve because FAME Bio-diesel is a very active solvent. Bio-diesel can also remove the protective coatings used in fuel tanks which then block fuel filters. 

 

All diesel engines will also burn Bio-power MWVF without any modification, but the fuel runs especially well in larger engines, indirect injection engines, and engines with turbos.  Mercedes, VW, Renault and Peugeot engines work very well on Bio-power MWVF.  Most engines will run even better on MWVF if they are fitted with our simple heat exchanger to the fuel delivery system, and this also seems to improve performance.

 

Some engines will  also burn SVO without modification (like Mercedes and Volvo), but normally a heat exchanger and / or dual fuel system is needed.

 

Can I burn bio-fuels in a petrol engine?

NO, our current range of bio-fuels are not suitable for use in spark ignition engines and will damage the engine, but we know that we can make a fuel that will run in petrol engines.  Ethanol is an alternative fuel for petrol engines, and factories are now being developed to produce ethanol in the UK, which will be blended with mineral petrol, initially at 5%.

 

Are bio-fuels dangerous?

NO, bio-fuel presents a lower fire risk than normal mineral diesel, and is about as safe as ordinary vegetable oil. Try lighting it with a match! All bio-fuels will only explode when heated and injected into highly compressed air. Spilled fat will dissolve into the ground like salad dressing.

 

Will using bio-fuel cause any damage my engine?
NO, you should find that it burns just the same as ordinary diesel, but it makes a nicer exhaust smell, and the engine may seem to run more smoothly with a grunt rather than a rattle.  Bio-diesel made as FAME is a very strong solvent and may cause damage to rubber parts in the engine or the fuel delivery system, and it can also cause blockage of fuel filters because it strips the paint or varnish from the insides of fuel tanks.  SVO and MUVO do not have these problems.

 

Can I mix bio-fuels with ordinary mineral diesel?
YES, the two types of fuel are absolutely inter-mixable, and can be burned together.  Most people mix bio-fuel with mineral diesel when they start using bio-fuels.  We recommend the mixing bio-fuels with ULSD during very cold conditions.

 

Do I need to alter the engine in any way?
FAME bio-diesel can be used in just the same way as ordinary mineral diesel, but care must be taken to prevent contact with rubber parts.  MUVO can be used in most engines without modification, but a heat exchanger improves performance.  SVO is a specialist fuel for those who are prepared to fit a new fuel delivery system.

 

Will bio-fuels be more expensive than normal mineral diesel?
At present the cost of collecting the fat, and processing it, plus the Excise Duty makes it difficult to produce BIO-DIESEL made as a Fatty Acid Methyl Ester that is competitive with mineral diesel. However, our fuel is normally between 10p and 15p per litre cheaper than ULSD in the UK.  This price includes the VAT and Duty.

 

Can I buy bio-fuels on a regular basis?
We hope that you will be encouraged to make a permanent commitment to the use of non-polluting fuels. Many organisations like the National Trust have already made a commitment to the use of non-polluting fuels. Our aim is to manufacture a range of organic fuels on a commercial scale that we can deliver to our customer’s homes. Most Bio-power agents will sell fuel in 15 litre or 20 litre returnable plastic containers, and can also deliver to customer’s storage tanks in quantities of 200 litres to 1,000 litres by pumped delivery.

 

Will burning renewable vegetable fuels provide any improvement in my engine's performance?
The tests we have so far carried out have not been conducted to any scientific standard.  But we do notice significant improvement in performance.  The improvement is greater in some engines than others suggesting there is a need for more research.  I suspect that the increased upper cylinder lubrication will give the impression of better performance.  It seems also that engines perform better when well warmed up - i.e. after about 10 to 15 minutes driving.  On a long drive I get the feeling the engine wants to 'fly' and one keeps lifting the accelerator pedal and there is no reduction in speed.  Bio-fuels also seem to provide more torque at lower revs, and so you tend to change up the gears faster, and you do not need to change down so much when you meet a hill.

 

I have plenty of waste vegetable oil which I have to pay to dispose of. Can you collect it?
YES, we will collect good quality oil from any restaurant, chip shop, or hotel in the UK.  If you have oil available then contact your nearest Bio-power Local Agent.  We can provide clean 20 litre sealed tubs for you to keep the fat until it can be collected. We do not charge for the collection, but neither do we pay for it.  We may pay up to 15p per litre for larger quantities of good quality fat, subject to contract.

 

Can I burn the vegetable oil I use to cook with as a fuel?
The government in the UK has now accepted that everyone can made 2,500 litres of bio-fuel for their own use without any need to register to pay the Excise Duty.  This is very similar to the dispensation provided to enable people to make their own wine or beer.  Many people are now using our basic method to meet their own fuel needs.  We do not recommend that home brew fuel makers buy supermarket veg oil, as this is highly selected material that is processed to be of food quality.  This processing serves no purpose if the oil is then used as a fuel.  We therefore suggest that you find a good supply of local used vegetable oil.  We find that food led pubs are the best source of clear runny oil.  The best oil is rapeseed oil, and it should look like good beer, i.e. clear and runny and a light amber to light brown colour.  Oil that is opaque or is black and bitter smelling is not suitable.

 

The use of straight unprocessed fat as a fuel does have some complications.  Diesel engines can be converted to burn unprocessed fat and waste vegetable oils, and we can provide further information about kits for most engines.  You will need to be good at adapting the basic kit to your vehicle. It is therefore a task for the enthusiast.

 

Our Bio-power MUVO is a compromise between the use of SVO but without the problems associated with Bio-diesel.  It is evident that the British Government does not want to support or encourage the use of SVO as a fuel and it is difficult to insure a vehicle that has been modified to run on SVO.  However, the use of SVO is very common in other European nations, and the use of SVO is recognised and supported by EU legislation.

 

It is also possible to make your own fuel using our method by following the steps set out in this web site.

 

 

About the taxation of bio-fuels:

Is it illegal to use bio-fuels?
NO, the government is keen to encourage the use of non-pollution fuels, so long as the relevant Excise Duties are paid. Duty is included in the charge for our fuels which is 20 p less than the rate charged on Derv.  In Germany, Italy and Poland there is no Duty on our form of bio-fuel.  As stated above there is now provision to allow people to make their own bio-fuel without paying Excise Duty.  

 

I want to make my own fuel and am having great difficulty getting the necessary forms to register to pay tax from HM Customs. What should I do?

The forms required to register for the payment of duty are published in the download section of this web site, together with guidance on how to register to pay the tax on your own home made bio-fuel.  However, it is not necessary to do this unless you plan to work on a commercial scale.

 

Do I have to pay Excise Duty on bio-fuel used in my tractor, boat or stationary engine?
NO, Excise Duty is only charged on fuel used for transport purposes. We do not charge duty on fuel sold to bona-fide users of red diesel for non-transport use. The quality of the fuel is exactly the same.  However, technically there is no provision yet in place for a marked or tax rebated form of a bio-fuel in UK.

 

What happens if I am stopped by the police, or asked about the strange smell of the fuel I am using?
Tell the police that you are using bio-fuel, and show them a receipt provided by BIO-POWER with each consignment of fuel. Give them our address and ‘phone number. North Wales Police are aware of our work in providing alternative forms of fuel for vehicular use. Car stickers are available explaining that you are using a new form of fuel.  Don't be ashamed to be using bio-fuels to protect the future of the planet.  Please contact us at once if ever you are stopped and the issue of using a bio-fuel is raised.  So far we have no record of anyone being challenged by the police or by HMRC.

 

About home heating:

The cost of kerosene (28 second heating oil) has increased enormously in the last few years.  Why is this?

The cost of kerosene has increased at a faster rate than the cost of petrol and mineral diesel because it does not carry the same rate of tax.  Any increase in the basic price of crude oil is therefore reflected directly in the retail price.  It is very likely that the cost of kerosene will continue to increase dramatically.

 

Can I use vegetable oil in my heating burner?

There are basically two types of kerosene burner used in most domestic heating installations, the drip feed system, and the fan assisted jet burner.  If you heating goes off when there is a power cut then you probably have a fan assisted system, and if the heating stays on when there is a power cut then you probably have a drip feed system.  Vegetable oil cannot be used directly in the drip feed system, because it will soon clog up the evaporation channels with unburned long hydrocarbon chains.  But it is possible to replace the burner with a vege oil burner.  I do heat our whole house and provide the hot water using a very simple home made drip feed system, which consists of two frying pans, one larger than the other, so the smaller one is placed inside the larger one.  The gap between them is maintained by a block of steel about 20 mm thick.  I simply pour the veg oil (all our rubbish oil) from a pyrex jug into the top frying pan.  It is lit with a briquette or wax based firelighter or small pieces of cardboard and paper, dipped in veg oil.  Once the oil is well lit it is simply a matter of refilling the top frying pan every twenty minutes or so.  The bottom frying pan is there as a safety measure to capture any spillage from the top one and allow it to burn without setting the house on fire.

 

Likewise veg oil can be used in fan assisted systems, but it is necessary to replace the burner head or adapt the burner significantly.  I have done this many times now, and it generally takes me two or three days to complete the task, and ensure the whole system is working reliably.  I am not a Corgi registered gas engineer and I do not take any responsibility for the safety of this equipment.  But it can work.  There is a need to provide a heated fuel tank, and I normally achieve this by converting an old copper water cylinder.  I turn it upside down so the dome on the top becomes a sump at the bottom.  I cut the bottom to provide a thistle funnel shape to pour the oil into.  I fit a tap to the outlet pipe to drain out any water and sediments.  The copper coil inside is used to heat the veg oil.  The immersion heater can also be used to heat the system from cold.

 

It is necessary to use a high pressure fuel delivery pump to provide the necessary backpressure to the fuel line.  I have found the high pressure pump made by Dunphy of Rochdale to work well.

 

I make a special fuel delivery pipe from the boiler to the fuel tank that has a 25mm copper pipe for the oil feed, which is inside a wider plastic pipe to carry water from the boiler to the fuel tank.  I separate the two pipes with a winding of fencing wire like a spring.  This keeps the two pipe concentric, and also ensures the hot water maintains maximum heat loss to the central copper pipe so the fuel gets hotter and hotter as it gets closer to the boiler. 

 

I then convert the boiler by fitting a super heating coil of 8mm thick gage pipe inside the burning chamber.  I find two and a half turns to be sufficient.  The pipe is then formed into another heating coil outside the burning chamber, formed around a 25 broom handle.  The pipe must be filled with oil or water under pressure to make a clean coil without any crimping.  This pipe then leads very hot or vaporised fuel to the burner head. 

 

The final part of the conversion is to identify the electric circuit that is operated by the thermostat.  This type of burner normally operates until the water is hot enough and then it closes down.  When the water gets too cool the burner is relit and drives until the water is hot again.  However, vege fuels will not want to be re-lit.  It is therefore necessary to swap between a full blast and pilot mode.  The burner will say alight when in the pilot mode.  This is achieved by inserting a suitable rheostat into the motor circuit on the off mode, so the fan motor remains running but the flame is smaller.  This rheostat is adjusted until the flame laps the coil sufficiently to transmit most of the heat to vaporising the fuel.  The system is started by heating the external coil with a gas torch for 15 minutes or more so there is a good flow of vaporised fuel coming from the burner jet.  The system is then switched on and the spark should light the flame.  You may need to keep heating the coil until the flame provide sufficient heat to maintain continuous burning.  The coil will have to be positioned carefully to achieve this.  I find about 15 to 20mm above the flame is generally sufficient.  When the water is up to temperature and the boiler switches to pilot mode it is necessary to adjust the rheostat to maintain the right amount of air flow to the jet.  The flame will lift as the jet is slower and thus more heat is transferred to the coil.

 

When everything is working well I seal the aperture into the boiler with fire cement.

 

Bio-power can also provide new German made burner heads that are designed to run on veg oil fuels.  Further information is available.

 

Can I convert my own burner to run on veg oil?

Yes, but it is not a project we recommend unless you are very committed, and can source your own fuel supply.  Palm oil obtained from traditional Fish & Chip shops is the best form of fuel for home heating.  Further information is available.

 

 

About Bio-power Seminars:

 

How can I get more involved with Bio-power network?
The first step is to get on our mailing list as a supporter or an  ordinary member.  You will then receive Bio-power News - our regular magazine in pdf format. The next stage is to come on one of our Introductory Seminars, which are held at least once every month.  This provides a thorough background to the workings of the Bio-power Network, the techniques we use, and an overall view of all the regulations that must be followed if you are to set up to make fuel on a commercial scale.

 

Having attended a Seminar it is possible to access to the Bio-power members web site and to our technical resources.  You will be able to attend our regular meetings of the Maker's Forum, that are convened about every three months, and also Regional Cell meetings in your locality and meet other people who are supporters, members or developing fuel makers.

 

You may then be invited to apply for full membership of the company, which will enable you to gain access to the Members web site, and technical meetings on a wide range of subjects that are open only to full members.

 

How are the Introductory Seminars run?
We normally run the Introductory Seminars at least once every month.  The first is on the second full weekend in each calendar month.  The second is held two weeks later if there is sufficient demand and we do not have other meetings or technical workshops that weekend.  We aim to have between 6 and 10 people attending each Seminar.  However, because of illness I have been unable to run many seminars over the last three years and we now have a considerable backlog.  The best thing is to get on our pre-seminar mailing list and you will then receive news as soon as the program is started again.

 

Can I come to a Seminar with my partner or other people from my company?
Yes, we encourage you to bring as many eyes and ears as you can, and every extra person is charged at a reduced rate.  The same rate applies if anyone re-attends the Seminar, which a number of people have done and found doubly beneficial!

 

How do people get on the seminar program?
When people express an interest in attending a Seminar we put their details on a rolling list called the pre Seminar list.  Details of the venue of each Seminar is then sent to everyone on that list about 2 weeks prior to each Seminar, with a booking form.  Bookings are accepted on the return of a copy of the booking form with a deposit.  The deposit is not returnable in the event that the person does not attend.

 

But I can't afford the seminar fee plus the cost of travelling and accommodation.
The seminar fee is kept as low as it can be for the quality of the service we wish to provide.  We only make any profit if there are more than 8 people attending.  However, the fee is not meant to become a barrier to participation in Bio-power.  We therefore keep a rolling fund to help support people who otherwise would not be able to attend the seminar, and this is prioritised to people from overseas.  If there are genuine reasons why you can't afford the fee, then let us know before you place a booking.

 

If I have attended an Introductory Seminar, can I then become a Bio-power Agent?
Not immediately.  You must first be accepted into the Bio-power Makers Community, and if there are other people setting up in your geographical area then we seek to achieve the best use of resources by helping people to work co-operatively.  Decisions about the inclusion of new agents in a region are decided by all those affected at a Regional Cell meeting.  People becoming a local agent must meet the criteria we set in terms of the quality of the fuel produced, the method used, and the way the company is presented.
