| Several cities, including the Austrian city of Graz, have already made the move to either biodiesel or biogas public transportation systems. |
| A part of the biogas is CO2, which gets separated from the biomethane and recycled. |
| Another creative idea of the time saw 80 council vehicles powered by biogas produced at the Christchurch sewage plant. |
| The colossal amount of animal manure produced will be used for generating biogas and as fertiliser. |
| Substituting LPG with more efficient and cheaper fuels such as biogas of firewood can minimise the escalating costs. |
| But India's government may not have a choice but to keep pushing for the wider use of biogas and other alternative fuels. |
