Yes, absolutely yes, and it's being done here in the City of Christchurch, New Zealand. (Co-incidentally the same city which was hit simultaneously by two major eathquakes of magnitude 7.4 and 7.1 just over a month ago, and has so far received over 1400 aftershocks up to magnitude 5.6, and counting...)
Christchurch is a city of roughly 500,000 people and every household has been given 3 wheelie bins - a green one for organic garden waste which is used for composting and bio-fuel production using locally designed and built massive anerobic digesters and other processes
- a yellow one for recyclable materials like paper, cardboard and plastic
- a red one for other waste which goes to the landfill
Check out the first link below and follow other links from there about the green and yellow bins.
PLUS, Christchurch has a pilot development in progress to produce bio-crude oil from the city's sewerage, using High Rate Algal Pond (HRAP) technology, also locally developed. Yet another local development is the Super Critical Water Reactor technology being used. This bio-crude can be processed into a wide variety of fuel products, including ethanol for example.
High Rate Algal ponds with CO2 addition require only a fraction of the land area of conventional open "oxidation" ponds (less than 20%), and have the added bonus of being able to produce bio-crude oil using simple gravity-based harvesting techniques. This bio-crude can be used to produce transport fuels.
Check out second the link below. NIWA is New Zealand's very progressive National Institute of Water and Atmospheric Research.
Exciting stuff! And I absolutely agree it would be criminal if organic waste from your city is simply being dumped in a landfill.
