[SIZE=1][SIZE=2]No sarcasm intended below. Just plain INFO that we can learn from. Yesterday my post mentioned how the Dutch (Netherlands) allotted Four Million Euro for biogas-run buses. Below is an excerpt about how 11,500 vehicles in Sweden run on biogas and the practice is growing.[/SIZE] [/SIZE]
[SIZE=1]Biogas has been used as vehicle fuel since the beginning of the 90´s in Sweden. So far there are 30 upgrading plants in operation or construction phase, which makes Sweden a world leader in this area. Today there are over 11 500 vehicles that use methane fuel in the country. Biogas is used in large scale systems and in several cities like Kristianstad and Linköping all of the city buses run on biogas. The market for biogas as vehicle fuel is growing in Sweden and the sales increased with almost 50 % 2006 compared with 2005. [/SIZE]
It is very easy to make biogas (in the Philippines where the temperature is ideal) using animal waste from large and small pigfarms that are very abundant. The effort also helps prevent Global Warming bigtime because biogas is a very POTENT greenhouse gas.
Or, until technologies are developed for turning algae (another abundant, easy to propagate and Global Warming-friendly feedstock) into biofuels, it can be used to make biogas.
