The Corporation For Future Resources (CFR) is dedicated to the efficient conversion of biomass (vegetation) under anaerobic fermentation conditions into renewable resources methane rich gas containing on the average 60% methane and 40% carbon dioxide as well as outstanding compost-fertilizers.
Our proprietary technology is most applicable to tropical and semi-tropical regions that historically support agriculture to be used for energy-compost-fertilizer purposes.
² CFRs renewable energy technology, evaluated as meritorious by USDOE,
² Includes the production of outstanding compost-fertilizers
² Uses a giant legume, leucaena; or
² Whole unburned sugarcane and thus 15 to 30% more biomass than burned cane;
² ( Sugarcane URL: http://wire0.ises.org/entry.nsf/E?Open&project&00031306 )
² In both instances, the biomass is harvested and cut and
² Processed to increase particle area using a corn silage harvester or similar harvester
² Biomass so treated is logistically easy to move;
² Since digester sites are located within less than a mile of biomass fields;
² The technology involves very low capital costs
² In the case of sugarcane nitrogen is needed in anaerobic processing
² Legume providing nitrogen -- our legume of choice is, again, leucaena.
² Product gas -- 60% methane and 40% carbon dioxide
² Is piped to a central location and used either directly or separated
² Providing methane for any energy as an exact substitute for natural gas
² Plus carbon dioxide that, if economically feasible, is separated as a liquid for freezing, carbonation and other uses.
² The organic compost-fertilizers -- liquid -- as a foliar or ground spray and a
² Solid -- an organic compost-fertilizer.
² On average, 60-70% of the feedstock dry mass goes in the energy direction
² While the included water and remaining dry mass moves in the fertilizer direction
² Substantial carbon sequestration is continuously obtained overall
Energy-Crop Anaerobic Fermentation
Leucaena, as a legume, possesses leaves that are very rich in nitrogen -- the young plants find use as a cattle feed. Similarly, nitrogen is an essential ingredient in methanogenic anaerobic fermentation. Under our conditions, however, Leucaena that is relatively young, three to six months old, is the preferred fermentation feedstock. Leucaena can be cultivated as separately spaced trees, next photo, or as closely placed bushes, following two photos. The bush growth pattern follows when plants are placed close together and are harvested frequently. The best harvest conditions are found when plants are separated by about 6 inches. This is the case in the third photo, below. In our experience, the six-inch configuration, with alleys between rows, leads to convenient harvesting with a Claas harvester, fourth photo, below.
Leucaena grown as closely spaced trees. The photo, above shows a 4-year old planting with trees 3 on center.
Leucaena is a perennial whose yields generally increase after cuttings. Above, Leucaena growing on central Florida sand about 16 months after first cutting. Yield, on planted area, was 25 dry/ton/acre/year
Leucaena, grown on clay-settling areas, reclaimed phosphate lands, in Polk County, FL. This three-acre, gross, area had been cut in March 2000. Above, photo shows growth after three months.
Leucaena, at three months after first cutting as shown in previous photo -- harvested and processed using a Claas corn silage harvester-processor, above.
This growing-harvest strategy can result in yields as high as 25 dry tons per acre-year.
Leucaena, harvested and processed, prepared for use as the anaerobic fermentation feedstock. This product affords an economically feasible basis for energy crop based project development under suitable climatic conditions that exist in may applicable areas of the world.
