Methane Digesting Unit Design Improvement

I have been researching and trying to improve the designs of some existing methane digestors.

Here is what I've come up with so far....

Methane Digestor Units in Series

CO2 Scrubber Unit

Biodiesel from Fish Oil Byproduct

Soap Making

Use left over fat from animal processing, and glycerine from biodiesel production to make soap.

Bio-Diesel Production

Transform used cooking oil into biodiesel for powering trucks and tractors.

Government Regulations:
See: REGULATORY REQUIREMENTS FOR BIOFUEL PRODUCTION FACILITIES

a. Used Cooking Oil collection (paid for)
b. Algae (grown) (Video US Dept. of Energy: From Algae to Oil to Gas)

Methane Producing System Overview

A system where anaerobic micro-organisms digest manure in a slurry and produce methane gas in the process. Coupled to a compressor and stores Methane in tanks similar to propane tank of a gas grill.
