Summary of some criteria used for the selection of biomass for bioenergy.

Applications	Criteria	Sub-criteria	References
Selection of the most appropriate crops	Irrigation demands, Fertilizer demands, Crop yield production, Labour, Energy plant calorific value		[14]
Sustainable biomass crop selection	-Economic -Environmental -Social	-Seeding, biomass yield, production and harvesting, transportation and storage, conversion rate, robustness to risk, equipment & knowledge -Soil quality, carbon emission, Water quality/requirement, biodiversity and wildlife, invasiveness -Technological development, workforce requirement, energy safety and welfare, food competition	[15]
Sustainable energy crop selection	Photosynthesis type, soil carbon sequestration, water adaptation, N input requirement, erosion control, the yield of dry materials, energy yield		[16]
Selection of biomass materials for bio-oil yield	Lignin, cellulose, hemicellulose, volatile matter, fixed carbon, moisture content, and ash content		[17]
Appropriate biomass resources for energy production selection	Creating technical side jobs, reserving non-renewable energy resources, the relative advantage of biofuel productivity, the complexity of the biofuel production process, cost of the biomass conversion process, biomass reusability, cost of biomass supply, environmental impacts of biomass accumulation, adaptability of the biofuel production process to the size of biomass production units and the attitude and knowledge of the producers, and energy self-sufficiency of the biomass producer		[7]
Microalgal biomass selection for biofuel production	-Technological -Environmental -Economic -Social	-Energy content, energy efficiency, ease of harvesting, primary energy ratio, biomass content, oil content, lipid content, fatty acid profile, growth rate, reliability, Safety, availability of nutrients -Land/waterbody use, water quality requirement, biodiversity and aquatic life, CO2 sequestration ability, Cultivation methods, pollution, chemical usage, light intensity, resistance to contamination, particles emission, impact on ecosystems, visual impact -Microalgae cost, investment cost, cost of cultivation, cost of harvesting, co-utilization, robustness, storage cost, transportation cost, payback period -Competition for food, technological development, sustainable development, social acceptability, job creation, social benefits	[18]
Biomass production from crops residues	-Economic -Environmental	-Gross Margin, income, variable cost -Biomass production, production of thermal energy, production of electrical energy	[19]
Biomass type selection for boilers	Efficiency, fuel price, ease of operation, global warming potential, and acidification potential		[20]
