Hello James Previously you were talking of WVO, I presume you mean that rather than SVO. "UVOME (biodiesel from waste vegetable oils): The maximum feasible production is smaller, at around 100,000 tonnes per annum, unless there is a significant increase in the amount of waste vegetable oils recovered from small retail establishments and domestic households." -- THE ROLE FOR RENEWABLE TRANSPORT FUELS IN THE UK Andrew Short. DETR, Great Minster House, Room 4/17, 76 Marsham Street. London SW1P 4RD. E-mail andrew_short@ detr.gsi.gov.uk Transport, Environment and Taxation Division Department of Environment, Transport and the Regions December 2000 However, a British biofuels campaigner commented to me at the time: "Wrong, we only collect that much but per-capita usage is 35kg per annum of which 15kg to 20kg is used in fryers. That works out at the thick end of 1 million tonnes per annum. We may not get all of that, but certainly a lot more than 10% of it." So there you go - anywhere between 100,000 and a million tonnes a year, close your eyes and chuck a dart. Also, you may be able to extrapolate from this: "Waste cooking oil from the catering industry: Over 100,000t of oils and fats are imported into Ireland each year (Central Statistics Office, 1997). The usage of oils and fats amounted to 35.4 kg per capita in 1995, below the EU average of 41.9 kg(Anon, 1997). Trade sources estimate that about 45-50,000t (15 kg per capita) of this material is used for cooking, mainly in households or in catering. No estimate is available of the amount of waste cooking oil that is potentially collectible for recycling, but about 5000t is collected at present, mainly from the catering trade. Estimates of collectible waste cooking oil from other countries vary from 13 kg per capita per year in Belgium to 5 kg per capita per year in Austria (Pelkmans 1996, Mittelbach 1996). Mittelbach also shows that 41% of the waste oil in Austria arises from catering and industrial use, which is relatively easy to collect (Mittelbach, 1996). "If the Austrian data is applicable to Ireland, it suggests that about 10,000t of waste oil could be collected from catering and industrial users. If the same holds throughout the EU, then the total amount of readily collectible waste cooking oil exceeds 1 million tonnes. The use of this material for bio-diesel would allow the production of the industry to be more than doubled from its present level. The end user of the collected product throughout the EU at present is almost exclusively the animal feed industry. There is a risk that tightening controls on animal feed quality may eventually put an end to this usage; this has already happened in Austria and Germany. It is likely that the uncollected waste oil is being dumped into sewage systems or land-fill sites, thereby generating additional waste disposal problems. "Waste oil collectors do not usually make any payment for the oil, but collection and cleaning costs are high. The price available from the animal feed industry in Ireland has varied between ĢIR140 and ĢIR220 per tonne in recent years The quality of this material may be expected to vary between countries, depending on the vegetable oil used, and variations in cooking practices and waste oil storage and collection systems." - from Bio-diesel Production based on Waste Cooking Oil: Promotion of the Establishment of an Industry in Ireland ALTENER CONTRACT No. XVII/4.1030/AL/77/95/IRL Final Report, Sept 1997 W.

We'd appreciate a progress report, or some sort of feedback.
