curious about the cost of it all though, and whether it can be applicable at individual building or building complex level.
technology that is feasible at municipal level only barely interests anyone.

I recently visited a Sanitation plant in Flagstaff Arizona. The plant currently has a digester that produces Methane which is used to run a co generation plant that produces Electric power needed to operate the system. They use the heat from the methane generator to heat the digester and the system is pretty efficient.

This system is taking sludge from human waste and converting it to power. While the system does use some of the sludge after ten days the sludge is removed from the digester and buried.

The waste produced from this system has all of the necessary elements needed for algae production. It produces large quantities of water, Nutrient rich Sludge, and CO2. At the most basic level this system could be expanded to to grow algae and just put the algae into expanded digesters to increase methane output and ultimately increase the power produced by the power plant. The power plant could be expanded to provide power for others not just the Sanitation plant.

The is a basic step that I feel will be a part of the future where we look at waste as an energy source not something we must pay to get rid of.
