Philippine Case Studies #4 & #5

Garbage Trucker sounds like a smart guy.

Could those tree cuttings also produce gas as they are composting down.. (Also heat...but I don't s'pose they need any more heat in Manila?)
This report makes garbage collection sound actually exciting...

Ernie,

Both fall directly into the bio-digestion area but in different ways.

Case #4 would use a bio-digester like as proposed in Case #3 for barn cleanup after Goats and pigs. It would be difficult to collect free range chicken droppings unless the roost at night in a "hen house". The effluent from the manure bio-digestion is an excellent fertilizer for his trees and is equal to the composted manure he is currently using.

As for the "cured" coffee bean shells, they too can be collected and digested, but it might be better to use a Siemens type gas generator. This would also work for the downed trees, tree trimmings and weeds collected in the coffee and coconut plantation. You do not say whether the farmer processes the coconuts, but the coconut shells could also be passed through the gas generator. Since the gas generator works by putting high pressure steam at 1000°F or there abouts to "reform" the carbohydrates to produce hydrogen, methane, and carbon monoxide, I would suggest you obtain a Siemens type SOFC and use the heat generated to drive the gas generator. This is very similar to the schema I am proposing to the City of Houston, Texas with my HARP-SEProject. I am sure that the people with Agro-Biogenics can work out the material and heat balance for you or you can contact Siemens and ask them for a quote/bid on the system.

For case #5, the same principles apply, for the kitchen wastes (also human and animal wastes)can be made quite safe with a properly designed bio-digestion system. With this schema, again, the effluent can be made it to a high quality and marketable fertilizer. If designed correctly, the effluent can then be drained into the Laguna lake, however, the effluent should be tested on a regular basis to be sure that there is no upset in the system.

For the solid wastes, after the Materials Recovery Facility, the solid organics such as paper, baby diapers, tree limbs, grass clippings, etc. can go into a gas generator and SOFC/GT Hybrid system for electric power generation power generation. Again, you can ask the Agro-Biogenics Corporation for details or you can ask Siemens or other similar companies for quote/bids.

Charles,

Thanks for your inputs. Regards.
