Carlos Buttner, former teacher at the Faculty of Chemistry, he had a small detergent plant named HARDY, now he added a small Biodiesel production facility, it is production capacity less than 2 ton/day. I know he is building another bigger one. There were some articles on the local newpapers after the Mayor of Asuncion anounced that the he wants the bus companies to use BD 20 as a means to diminish the pollution from petroleum diesel particles and the cost of the fuel. One of those bus companies is the Line 25, they were testing the performance of BD 20 in their busses. After this I talked to Buttner and he told me he was very bussy doing BD at this moment for that bus company. In fact it is cheaper to use here BD 20 or even better BD 100 compared to petroleum diesel, and the some agricultural cooperatives that produces and exports large quantities of soybeams (Paraguay in year 2000 ranked fourth 2.5 Millio Metric Tons in soy beams exports after US, Brazil and Argentina; Soy Stats 2001 p. 44 on SoyGrowers.com ) are interested to produce large quantities for their tractors, the aim is to reduce the fuel cost, see: http://www2.uhora.com.py/vida/vida_219/diesel.htm It is in Spanish but I think all of you could do a Google translation to read it in you own language. One newpaper from Peru has some news on the same: http://www.elcomercioperu.com.pe/Online/Html/2002-09-29/OnlEconomia4175. html Buttner is using 100% Ethanol produced at the state owned Petroleos Paraguayo's Ethanol Plant in Mauricio Jose Troche, it has a big alcohol distillery, it was designed for the production of E95 and anhydrous ethanol to use as a mixt with gasoline at 8 - 10% Ethanol. Others, like a recycling company is preparing a bigger BioD plant and maybe that will be ready in the near future. http://www.ecoindustria.com/recicladats.html Reciclajes del Paraguay, S.A.

Sorry, I asked among some of my friends working with organics sweetners and I could not find if there is someone to attend that International Organic Conference. About organic food exports to Japan, there was a front page report in the Diario ABC from Sunday, September 8, 2002; it says in Spanish "Indigenas del Chaco exportan al Japon". It translated means: "Aborigins from the Paraguayan Chaco exports to Japan" It is about the export of 650 metric Tons of sesame seed with an income for them of US $ 226,605. It stated with only 68 Ha. in 98's with 166 producers and now there are 2300 Ha. and 1351 producers in one the dryest region of my country (this week max. temperatures were in the 40 -43 Celsius range).
