Analysing alternative options of using existing sludge digesters, e.g. using other feedstock.
Moreover, supply chains for biomass are still being developed, so the availability of feedstock will change.Research is continuing into using other micro-organisms, such as yeast, which might be engineered to create similar metabolic pathways.
Because of this, different pretreatment and saccharification conditions are likely to be needed, compared to those used with other feedstock.
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.
Morrell says it includes safeguards to make sure wood and other feedstocks used are sustainable, as well as to preserve biodiversity and to give work to local people.
Global demand for food, as well as for corn and other feedstocks used to make ethanol, mean boom times for farmers.
HTL conducted at 300 °C resulted in lower solids than at 240 °C, which is in good agreement with studies using algae [ 7] and other feedstocks [ 22, 25, 27].
The relative benefit of producing biochar compared with bioenergy is greatest when biomass crops are used as feedstocks (Fig. 7b), because avoided CH4 emissions from the use of manure, green waste and rice residues occur regardless of whether these other feedstocks are used for energy or biochar.
M&G plans to use wheat straw, nonfood crops and other feedstocks, while Fiberight plans to use municipal solid waste.
Owing to these drawbacks one speaks of first-generation biofuels in contrast to second-generation biofuels which rely on the use of lignocellulose or other feedstocks that do not directly compete with food, and reduce the need for agricultural land [ 13].
