“…Cultivating perennial bioenergy crops on marginal agricultural land will require sustainable fertilization strategies allowing for a successful establishment of the crops and a high biomass productivity, while avoiding nutrient leaching and potential aquifer pollution. For example, when cultivating Virginia mallow [182] in marginal sandy soil, digestate fertilization resulted in significantly less N leaching compared with NPK fertilizer but similar biomass yields and an increased soil carbon content, water holding capacity, and soil basal respiration, indicating an improved fertility of the marginal soil [132,183]. Other perennial biomass crops such as giant reed have the characteristic of leaving very low amounts of residual soil nitrate after harvest, which also helps in reducing potential N leaching over winter [184].…”

“…Furthermore, the accumulation of heavy metals within the biomass value chain (e.g., within the biogas value chain) must be avoided. This could be done by using another utilization pathway such as combustion [182,230,231]. For combustion, the heavy metal content will be highly concentrated within the ashes of the processed biomass.…”

Prospects of Bioenergy Cropping Systems for A More Social-Ecologically Sound Bioeconomy

The growing bioeconomy will require a greater supply of biomass in the future for both bioenergy and bio-based products. Today, many bioenergy cropping systems (BCS) are suboptimal due to either social-ecological threats or technical limitations. In addition, the competition for land between bioenergy-crop cultivation, food-crop cultivation, and biodiversity conservation is expected to increase as a result of both continuous world population growth and expected severe climate change effects. This study investigates how BCS can become more social-ecologically sustainable in future. It brings together expert opinions from the fields of agronomy, economics, meteorology, and geography. Potential solutions to the following five main requirements for a more holistically sustainable supply of biomass are summarized: (i) bioenergy-crop cultivation should provide a beneficial social-ecological contribution, such as an increase in both biodiversity and landscape aesthetics, (ii) bioenergy crops should be cultivated on marginal agricultural land so as not to compete with food-crop production, (iii) BCS need to be resilient in the face of projected severe climate change effects, (iv) BCS should foster rural development and support the vast number of small-scale family farmers, managing about 80% of agricultural land and natural resources globally, and (v) bioenergy-crop cultivation must be planned and implemented systematically, using holistic approaches. Further research activities and policy incentives should not only consider the economic potential of bioenergy-crop cultivation, but also aspects of biodiversity, soil fertility, and climate change adaptation specific to site conditions and the given social context. This will help to adapt existing agricultural systems in a changing world and foster the development of a more social-ecologically sustainable bioeconomy.

“…Biomass quality for combustion is defined by its moisture content, which changes with harvest time. If S. hermaphrodita is to be used for biomass combustion, delaying harvest until the end of winter allows the material to dry on the field, lowering moisture and ash content [55], achieving moisture contents of around 20% and, therefore, minimizing drying costs. In contrast, willow and poplar contain 45-60% moisture when harvested [123] and does not vary much with harvest date [124].…”

Two Novel Energy Crops: Sida hermaphrodita (L.) Rusby and Silphium perfoliatum L.—State of Knowledge

Current global temperature increases resulting from human activity threaten many ecosystems and societies, and have led to international and national policy commitments that aim to reduce greenhouse gas emissions. Bioenergy crops provide one means of reducing greenhouse gas emissions from energy production and two novel crops that could be used for this purpose are Sida hermaphrodita (L.) Rusby and Silphium perfoliatum L. This research examined the existing scientific literature available on both crops through a systematic review. The data were collated according to the agronomy, uses, and environmental benefits of each crop. Possible challenges were associated with high initial planting costs, low yields in low rainfall areas, and for Sida hermaphrodita, vulnerability to Sclerotinia sclerotiorum. However, under appropriate environmental conditions, both crops were found to provide large yields over sustained periods of time with relatively low levels of management and could be used to produce large energy surpluses, either through direct combustion or biogas production. Other potential uses included fodder, fibre, and pharmaceutical uses. Environmental benefits included the potential for phytoremediation, and improvements to soil health, biodiversity, and pollination. The review also demonstrated that environmental benefits, such as pollination, soil health, and water quality benefits could be obtained from the use of Sida hermaphrodita and Silphium perfoliatum relative to existing bioenergy crops such as maize, whilst at the same time reducing the greenhouse gas emissions associated with energy production. Future research should examine the long-term implications of using Sida hermaphrodita and Silphium perfoliatum as well as improve knowledge on how to integrate them successfully within existing farming systems and supply chains.

“…The depletion of fossil fuel sources, the wobbling prices of fuels, and the increased pressure regarding environmental and social aspects have increased the industrial focus towards renewable energy resources such as organic waste [1][2][3][4][5][6][7][8][9]. Organic residues have been considered an inexpensive, renewable, widely available, and environmentally friendly feedstock for biofuels production [10][11][12][13][14]. Currently, large quantities of biofuels are generated from first-generation resources, such as starch, corn, and sugar [15][16][17][18][19].…”

Feasibility Assessment of a Bioethanol Plant in the Northern Netherlands

et al. 2019

Due to the exhaustion and increased pressure regarding the environmental and political aspects of fossil fuels, the industrial focus has switched towards renewable energy resources. Lignocellulosic biowaste can come from several sources, such as industrial waste, agricultural waste, forestry waste, and bioenergy crops and processed into bioethanol via a biochemical pathway. Although much research has been done on the ethanol production from lignocellulosic biomass, the economic viability of a bioethanol plant in the Northern Netherlands is yet unknown, and therefore, examined. In this thesis, the feasibility study of a bioethanol plant treating sugar beet pulp, cow manure, and grass straw is conducted using the simulation software SuperPro Designer. Results show that it is not economically viable to treat the tested lignocellulosic biomass for the production of bioethanol, since all three original cases result in a negative net present value (NPV). An alternative would be to exclude the pretreatment step from the process. Although this results in a lower production of bioethanol per year, the plant treating sugar beet pulp (SBP) and grass straw (GS) becomes economically viable since the costs have significantly decreased.
