A collection of notes about making biodiesel
I've tried to develop the traditional biodiesel process, to greatly reduce the need for methanol, and to use techniques to limit its release into the environment, which is one of the most challenging ecological risks in the biodiesel process. The use of water in the purification/washing process has also been largely eliminated.
::: Processor designs - minimal methanol release, no water wasted.
- EcoSystem processor - needs no water, recovers methanol (GL 1 day system)
- Advanced Push-Pull processor. Methanol recovery from biodiesel & glycerol
::: System components
- Soldering copper pipe - a simple guide
- A safer electrical heater design
- Plumber's delight methanol recovery condenser
- Make your own vacuum venturi
- A simple pump throttle system
- Carboy filling vents
- Simple, safe stirrer for dissolving lye in methanol
- Never-overflowing wash tank
- Re-ranging a British thermostat
- Electrical control ideas for heater and pump
- Electrostatic glycerol separation videos & ideas
- Electronic dipstick to detect the glycerol or water layer
- Electronic colour detector for titrations - helps automate the process
- Simple solar detector and motor positioner
- A non-glug filler can for fuelling your car.

::: Safety notes
Making biodiesel involves poisonous, corrosive, flammable chemicals.
WEAR CHEMICAL SAFETY MASK and CHEMICAL RESISTANT GLOVES when you use Methoxide, NaOH, KOH, Methanol, H2SO4, HCL. Do not breathe methanol fumes. Wear a dust-filter mask when you use KOH flake.
Do not make biodiesel in a house or attached garage - use a lockable, ventilated out-house, with running water, suitable fire extinguishers, and suitable safety notices on all hazardous chemicals.
- Pressure testing a tank - beware!
- First aid for chemical burns
- Protect yourself from splashes and burns
- Breathing apparatus for your safety
- MSDS Safety details for Methanol

If any of this information has helped you, may I ask a BIG favour?
If you can, may I ask you to help with a donation, no matter how small, to my fund raising?
To help raise awareness and vital funds for Sue Ryder Care hospices, I am entering the solo Silverstone 24 Hour Cycling Grand Prix on 14-15 September 2013.
My target is to cycle 366 miles in one day on a normal road bicycle.
