Biodigesters and feedstocks available in SSA were identified according to scale and application – household, community, institutional, and commercial.
The type and the capacity of the reactor, pyrolysis temperature, solid residence time, carrier gas flowrate, vapour residence time, and biomass feedstock type and size were identified as the parameters having the most influence on product yields and their properties.
Maize stover and sugar beet were identified as feedstocks with low emissions in all studies.
Other potential applications, such as biochart production, soil amelioration, and energy recovery of feedstock chars in combustion plants, were identified from a hydrothermal carbonization process.
Five counties in Sweden were identified as potential feedstock suppliers to a biorefinery processing 200 kt dry feedstock/y.
Feedstocks displaying the highest levels of lignin were identified as drupe endocarp biomass arising as agricultural waste from horticultural crops.
The 18 strains were identified and characterized for their lipid production as a feedstock for biodiesel production in the future.
Moreover, suitable feedstocks should be identified and characterized to facilitate the development of these processes.
This would make it easier to test the quality of 3-D printed objects, particularly as 3-D printing — forming an object layer by layer using plastic or other feedstock — has been identified as a way to manufacture parts in space, she added.
As microalgal derived fuels are inherently dependent on the cultivation of microalgae feedstock, a sustainable pathway for microalgae feedstock production must be identified if algal-based fuels are to become a commercial reality.
