IntroductionCurrent waste scenario overview
MissionFind if there is reliable biomass feedstock supply for long term productionHighlight commercially viable biomass to energy conversion approachOutline strategy for public-private partnership to develop biomass to energy Attract commercially proven developers to consider investment approach in SKN
ScopeFocused on sugarcane and municipal waste biomass availability on St. KittsFocus on liquid biofuel and electric power productionPotential for value-added products
Possible Process Overview
ChallengesEconomies of scaleModest biomass feedstock availabilityBiomass conversion technologiesLand use competitionInformation dissemination on sustainable alternativesFamiliarity with current methods of production
OpportunitiesEnvironmental/health benefitsCO2 reductionIncreased soil fertilitySanitary issuesJob provisionExistence of skilled labor force Energy securityEconomic Avoided investment cost: No need for additional landfill/waste management alternatives Decreased expenditures on electricityDiversification of economic activities
BiomassDefinition and SourcesOrganic matter, matter from any living organismAnimal/human wasteFood cropsGrassy and woody plantsResidues from agriculture or forestryOrganic component of municipal and industrial wastes
BiomassAs a renewable fuelNo net carbon emissions Carbon dioxide released when biomass is used as fuel is balanced by the carbon dioxide captured when the biomass is grown
BiomassConversion
BiomassConversions of interest
Combustion: direct-fired systems. They burn bio-energy feedstocks directly. Gasification: biomass is heated with no oxygen or only about one-third the oxygen needed for efficient combustion. Biomass then gasifies to a mixture of carbon monoxide and hydrogensynthesis gas or syngas. Biochemical: relies on the abilities of specific microorganisms to convert biomass components to useful liquids and gases, as ethanol or methane.
Bio Energy AssessmentObjective Financial and economic analysis of a potential Domestic Bio-Energy Programme to test its commercially sustainability
Bio Energy AssessmentMethodologyResource assessment (supply and demand)Technology identificationEvaluate economic and financial feasibility of technologies given the resource availability
Bio Energy AssessmentResource Assessment (1)Agricultural cropsSugarcane or palm oilCharacteristics of sugar caneYields and landCollection, processing, and transportResidues generatedStorage
