Types of Waste for gasificationHazardousWasteBiodegradableorganic waste• Are verypolluting• High humiditycontent, >70%Non-Biodegradableorganic wasteUsed tires

Advantages of the gasificationElimination of most of theincoming waste•Elimination between 80% and 98% ofthe waste depending of its nature.•The resultant ash, minimum volume,are inert•Easy to recycle or treat. Possibility torecover heavy metalsReducing the emission of gases•A 40% CO2 and 100% CH4•High filtration efficiency: it avoidsthe emission of toxic gases•SO2, SO3 and NOx (promoters of acidrain)•Dioxins and furans (carcinogens)High efficiencyand profitability• Lower cost per kWhgeneratedAbundance of fuel• No dependence onforeign• Usable in separateareasTo eliminate waste To generate electricity
Gasification advantages over othertechnologiesIncineration BiogasPlasmaGasificationPyrolysisGasification is the best technology for waste to energy from biomass and organic waste
Advantages of the gasificationfront of the incineration• In gasification, emissions ofhazardous compounds (dioxins andfurans) are 1.000 items smaller• The energy efficiency of thegasification is higher thanincineration, getting electricity andheat.• It generates 40% of CO2 less per kWhproduced.• Gasification allows smaller plants(from 0,5 MW)
Advantages of the gasificationfront biodigestionBiodigestionremoves 20% of theresidues, comparedto 90% of thegasification.The digesters areuseful with wetwaste.They can becomplementarytechnologies.
Advantages of the gasificationfront of the plasma gasificationThe plasma gasification works at 6.000ºCThe “classic” gasification requires lessinvestment and lower cost of operation andmaintenance as well be getting more profitable.
Advantages of the gasificationfront of the pyrolysisPyrolysis is only recommended whenthe proportion of organic matter inthe waste to value is low.
