Carbon-based waste only.... that's how it works. Oh...... "global warming" is caused by water vapor and solar activity...... but that's detailed in another thread. Carbon dioxide is plant food, not a polutant.
Coal-burning power plants, automobile exhausts, factory smokestacks, and other waste vents of the human environment contribute about 22 billion tons of carbon dioxide and other greenhouse gases into the earth's atmosphere each year. Animal agriculture, manure, natural gas, rice paddies, landfills, coal, and other sources contribute about 250 million tons of methane each year. About half of human emissions have remained in the atmosphere. The atmospheric concentrations of CO2 and CH4 have increased by 31% and 149% respectively above pre-industrial levels since 1750. This is considerably higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores. From less direct geological evidence it is believed that CO2 values this high were last attained 40 million years ago. About three-quarters of the anthropogenic emissions of CO2 to the atmosphere during the past 20 years is due to fossil fuel burning. The rest is predominantly due to land-use change, especially deforestation.

This site reports that greenhouse gasses are at the highest levels in over half a million years. Its time we stopped turning away from this fact and started doing something about it.
As for TDP, the federal Energy Policy Act now grants a dollar per gallon tax incentive on turkey biodiesel. This technology will see success sooner in Europe than anywhere else because of the Kyoto Protocol. Also, the US government is behind this, having provided half the construction funds for an entire plant.
