“…Biomass is considered a renewable energy resource as green plants receive power from sunlight to initiate chemical reactions that store energy. The consequence of these chemical reactions results in the generation of numerous types of energy-rich resources, including plants and trees, forestry residues, fruits and vegetable residues, and animal wastes (Maletta & Díaz-Ambrona, 2020). Technologies used for biological conversion of organic matter are combustion, gasification, pyrolysis, anaerobic digestion, and microbial fermentation, and the biofuels obtained as a result are syngas, bio-oil, bio-diesel, charcoal, biogas, methanol, and ethanol (Gao et al, 2018).…”

The world is facing a serious energy crisis and environmental pollution problems due to a sharp increase in the world population. Bioenergy is an eminent solution to these problems. Anaerobic digestion is a green energy technology used worldwide for the conversion of organic waste to biogas. It is reported that organic wastes are hard to digest and need some technical improvement in the anaerobic digestion process to improve biogas yield. Iron-based additives, due to their electron acceptance and donation capabilities, have been emphasized as being exceptional in improving anaerobic digestion process efficiency amongst all other enhancement options. This study reviews the major available types of iron-based additives, their characteristics, and their preparation methods. The preferred iron-based additive that has a significant effect on the enhancement of biogas yield is also discussed. The use of iron-based additives in the anaerobic digestion process with varying dosages and their impact on the biogas generation rate is also being studied. Substrates, operating parameters, and types of anaerobic digesters used in recent studies while researching the effects of iron-based additives are also part of this review. Lastly, this study also confirms that iron-based additives have a significant effect on the reduction rate of the volatile suspended solids, methane content, biogas yield, and volatile fatty acids.

“…Switchgrass is another warm-season, perennial, rhizomatous, C 4 grass, native to North America. This species is a leading candidate among herbaceous species to be developed as a bioenergy feedstock for cellulosic ethanol production, direct combustion for heat, and other technologies [16]. There are two ecotypes, lowland and upland.…”

“…There are two ecotypes, lowland and upland. The lowland ecotypes are preferable for the warm regions of Europe, whereas the upland ecotypes could be also grown in the cooler climatic zones [16]. In Greece, Alexopoulou et al [10] found that the lowland ecotypes yielded 14.9 t DM ha −1 y −1 while upland ecotypes yielded 13.9 t DM ha −1 y −1 .…”

Weed Management Practices to Improve Establishment of Selected Lignocellulosic Crops

et al. 2021

View full text Add to dashboard Cite

Lignocellulosic biomass is one of the dominant renewable energy resources suited for the production of sustainable biofuels and other energy purposes. This study was focused on weed management strategies that can improve the establishment of six lignocellulosic crops. The studied crops included: giant miscanthus, switchgrass, giant reed, cardoon, sweet sorghum, and kenaf. Delayed planting, increased planting densities, and mulching techniques can suppress weeds in giant miscanthus. Weed competition is detrimental for switchgrass establishment. Seedbed preparation and cultivar selection can determine its ability to compete with weeds. Giant reed is unlikely to get outcompeted by weeds, and any weed control operation is required only for the first growing season. Competitive cultivars and increased seeding rates maximize the competitiveness of cardoon against weeds. Several cultural practices can be used for non-chemical weed management in sweet sorghum and kenaf. For all crops, pre-emergence herbicides can be applied. The available safe post-emergence herbicides are limited. Mechanical weed control during crucial growth stages can provide solutions for sweet sorghum, kenaf, and perennial grasses. Further research is required to develop effective weed management strategies, with emphasis on cultural practices, that can improve the establishment of these prominent lignocellulosic crops.

“…The increased request of inputs will likely cause an increment of production costs, especially intensifying the competition between rural and urban areas for water use during summer [9,10]. Within this framework, new supply chains and processes have been developed and tested worldwide at lab and/or small scale in order to reduce the fossil fuel dependency through a responsible use of resources, while preserving the income of stakeholders of the energy sector [11][12][13][14][15].…”

Giant reed is a promising perennial grass providing ligno-cellulosic biomass suitable to be cultivated in marginal lands (MLs) and converted into several forms of renewable energy. This study investigates how much energy, in the form of biomethane, bioethanol, and combustible solid, can be obtained by the cultivation of this species in marginal land of two Italian regions, via the spatially explicit application of the Arungro crop model. Arungro was calibrated in both rainfed/well-irrigated systems, under non-limiting conditions for nutrient availability. The model was then linked to a georeferenced database, with data on (i) current/future climate, (ii) agro-management, (iii) soil physics/hydrology, (iv) land marginality, and (v) crop suitability to environment. Simulations were run at 500 × 500 m spatial resolution in MLs of Catania (CT, Southern Italy) and Bologna (BO, Northern Italy) provinces, characterized by contrasting pedo-climates. At field scale, Arungro explained 85% of the year-to-year variability of measured carbon accumulation in aerial biomass. At the provincial level, simulated energy yields progressively increased from bioethanol, to biomethane, and finally to combustible solid, with average values of 92-115-264 GJ ha−1 in BO and 105-133-304 GJ ha−1 in CT. Mean energy yields estimated for 2030 remained unchanged compared to the baseline, although showing large heterogeneity across the study area (changes between −6/+15% in BO and −16/+15% in CT). This study provides site-specific indications on giant reed current productions, energy yields, and natural water consumption, as well as on their future trends and stability, ready-to-use for multiple stakeholders of the agricultural sector involved in bioenergy planning.
