Only in that the methane is going to be produced in an anaerobic environment anyways. If the wastes were disposed of in an aerobic environment, it biodegrade more quickly without the methane production or the other unpleasantness of anaerobic digestion such as hydrogen sulfide. So it's only efficient in terms of our current inefficient means of waste disposal.
You would get more burnable gas more quickly by gasification of the waste into syngas plus syngas can synthesize liquid hydrocarbons such as gasoline and diesel and if the charcoal byproduct of gasification is used as biochar then carbon is sequestered and the fuels are carbon negative. Biogas is not the most environmentally friendly or efficient means available despite what many activists will claim.
As was mentioned by Chuckles, biogas is efficient depending on the feedstock, source, and the method of production. It can be extracted from a wide range of feedstocks each with varying levels of impact and efficiency.
For an accurate breakdown please see the paper I have referenced below.

Biogas produced from agricultural plants is a huge waste of good farmland. People starve as you drive your obscene SUV nowhere every day!
yes, is an efficient form of energy because biogas comes from manure of animals.
not especially
we're still burning stuff
and of course that which we're burning has to be grown, processed and transported
the most efficient leans towards energy as produced through utilising wind, solar, tide and other forms yet to be explored
Bio Gas is methane. It is efficient or not depending on how you produce it.
Yes its efficient. Its also much better than coal, petrol and other fossil fuels.
best is petrol, **** efficiency, get your self a 6.8liter engine and it must have at least 600horsepower , then you will get what im saying.
its good alternative but it cannot be said most effective and efficient
Meaning it can produce the maximum amount of bi-product with the least amount of waste (not including left over biomass because that is re-usable/decomposable).
