Energy Crops in sustainable phytoremediation
Renewable & Sustainable Energy Reviews, 2016Co-Authors: Vimal Chandra Pandey, Omesh Bajpai, Nandita SinghAbstract:Phytoremediation is a holistic approach and can be used in large scale to remediate the contaminated land resources. Although the concept of phytoremediation is few decades old and has been applied on a wide range of pollutants, but their sustainability is still questioned at various scientific forums. Therefore, it is the need of the hour to remediate our valuable resources with due considerations for future generations. Such a synergistic bonding by using potential Energy Crops in phytoremediation programs would be useful to generate new bioEnergy resources along with the remediation of contaminated soil. There are several Energy Crops in the world, but four promising and dedicated Energy Crops i.e. Miscanthus, Ricinus, Jatropha, Populus have primarily considered in this review to accomplish Energy demands with their phytoremediation potential. These four Energy Crops also act as potential carbon sink and offer an additional profit as carbon tax credits.

Energy Crops in rotation. A review
Biomass and Bioenergy, 2011Co-Authors: Walter Zegada-lizarazu, Andrea MontiAbstract:The area under Energy Crops has increased tenfold over the last 10 years, and there is large consensus that the demand for Energy Crops will further increase rapidly to cover several millions of hectares in the near future. Information about rotational systems and effects of Energy Crops should be therefore given top priority. Literature is poor and fragmentary on this topic, especially about rotations in which all Crops are exclusively dedicated to Energy end uses. Well-planned crop rotations, as compared to continuous monoculture systems, can be expected to reduce the dependence on external inputs through promoting nutrient cycling efficiency, effective use of natural resources, especially water, maintenance of the long-term productivity of the land, control of diseases and pests, and consequently increasing crop yields and sustainability of production systems. The result of all these advantages is widely known as crop sequencing effect, which is due to the additional and positive consequences on soil physical–chemical and biological properties arising from specific Crops grown in the same field year after year. In this context, the present review discusses the potential of several rotations with Energy Crops and their possibilities of being included alongside traditional agriculture systems across different agro-climatic zones within the European Union. Possible rotations dedicated exclusively to the production of biomass for bioEnergy are also discussed, as rotations including only Energy Crops could become common around bio-refineries or power plants. Such rotations, however, show some limitations related to the control of diseases and to the narrow range of available species with high production potential that could be included in a rotation of such characteristics. The information on best-known Energy Crops such as rapeseed (Brassica napus) and sunflower (Helianthus annuus) suggests that conventional Crops can benefit from the introduction of Energy Crops in the rotation; furthermore, a considerable number of lesser-known Energy Crops such as biomass sorghum (Sorghum spp.), hemp (Cannabis sativa), kenaf (Hibiscus cannabinus), Ethiopian mustard (Brassica carinata) could be expected to lead to even greater benefits according to literature. Therefore, this review aimed at systematizing and reorganizing the existing and fragmentary information on these Crops while stressing major knowledge gaps to be urgently investigated.

Agronomic aspects of future Energy Crops in Europe.
Biofuels Bioproducts and Biorefining, 2010Co-Authors: Walter Zegada-lizarazu, H.w. Elbersen, Salvatore L. Cosentino, Alessandro Zatta, Efthymia Alexopoulou, Andrea MontiAbstract:The recent policies enacted by the EU foresee an increased interest in the cultivation of Energy Crops. Hence systematized information on new Energy Crops and cropping strategies is necessary to optimize their produc- tion quantitatively and qualitatively and to integrate them into traditional production systems. This kind of information will offer farmers new perspectives and options to diversify their farming activities. Some of these Crops, however, may compete for land and resources with existing food Crops, while others could be grown in marginal/degraded lands with consequent benefi cial effects on the environment. Therefore choosing the appropriate management com- ponents and species should be site specifi c and oriented to minimize inputs and maximize yields. In some cases, tra- ditional food Crops are used as dedicated Energy Crops with the advantage that their management practices are well known. On the other hand, the management of new dedicated Energy Crops, such as perennial herbaceous Crops, often demands a range of structural features and tactical management approaches that are different to those com- monly used for traditional food Crops. Most of these Crops are largely undomesticated and are at their early stages of development and improvement. In this work, state-of-the-art research and development of agronomic management and the production of a wide range of multipurpose future Energy crop species are reviewed and where possible examples of appropriate crop management practices that would enhance Energy yields are provided. Interesting lines of investigation are also suggested. © 2010 Society of Chemical Industry and John Wiley & Sons, Ltd

Overview of the markets for Energy Crops in EU27
Biofuels Bioproducts and Biorefining, 2010Co-Authors: Myrsini Christou, Efthinia Alexopoulou, Calliope Panoutsou, Andrea MontiAbstract:Agriculture and forestry provide a wide number of Crops that are used for a range of non-food products, such as fuels, chemicals, fibers, construction materials, lubricants, etc. The term ‘Energy Crops’ is commonly used to indicate plants grown to make Energy, such as biopower, bioheat and biofuels. Nonetheless, the development and commercialization of Energy Crops can initiate new and expand current markets for agricultural feedstocks, reduce dependence on petroleum and other imports of critical materials, diversify agriculture, and strengthen rural and sustainable development. As demand is growing steadily both from policy and from industry (which seeks environmentally friendly feedstocks) tensions have already risen among sectors about securing their future supplies. Among the key drivers that promote the development of one or other market, in the short and long term, the following can be considered as the most important: regular Energy Crops' feedstock supply and consistency in terms of quantity and quality, sustainable growth and environmental impacts, market demands and state of development, price competitiveness, and technological scale-up. Taking these issues into account, this perspective is a concise review of the state of the Energy markets in the EU27 in the light of policy demand, economic and environmentally sustainable options, and the optimum choices of Energy Crops from 2010 to 2030. © 2010 Society of Chemical Industry and John Wiley & Sons, Ltd

mineral composition and ash content of six major Energy Crops
Biomass & Bioenergy, 2008Co-Authors: Andrea Monti, Nicola Di Virgilio, Gianpietro VenturiAbstract:Abstract The chemical composition of biofuels has not received adequate attention given that it is an important aspect in the introduction of Energy Crops. In this study, the ash content and mineral composition (C, N, Al, Ca, Cl, Fe, K, Mg, Na, P, S, Si) of stems, leaves and reproductive organs of some promising Energy Crops were determined and compared with the respective recommended thresholds reported in literature. Overall, cynara exhibited the highest ash and mineral contents, which indicate high slagging, fouling and corrosion tendencies. However, cynara also showed the lowest Si content, both in leaves (4.3 g kg −1 ) and in stems (0.9 g kg −1 ). Sweet sorghum and giant reed exhibited the highest N content (up to 16 g kg −1 ), which greatly exceeded the recommended limits in leaves. Importantly, Cl always exceeded the recommended limits (up to 18 mg kg −1 in cynara), both in stems and in leaves, thus resulting in a major stumbling block for all Crops. Several significant correlations among elements were found at a single plant part; conversely these correlations were generally very weak considering different plant components, with the exception of K ( r =0.91**), P ( r =0.94**) and ashes ( r =0.64**). Generally, leaves resulted in a significant deterioration of biofuel quality when compared with stems and flower heads. Therefore, agricultural strategies aimed at reducing the leaf component (e.g. by delaying the harvest) may considerably improve the suitability of biofuels for current combustion plants.

ecosystem service tradeoffs associated with switching from annual to perennial Energy Crops in riparian zones of the us midwest
PLOS ONE, 2013Co-Authors: Timothy D Meehan, Claudio Gratton, Erica Diehl, Natalie D Hunt, Daniel F Mooney, Stephen J Ventura, Bradford L BarhamAbstract:Integration of Energy Crops into agricultural landscapes could promote sustainability if they are placed in ways that foster multiple ecosystem services and mitigate ecosystem disservices from existing Crops. We conducted a modeling study to investigate how replacing annual Energy Crops with perennial Energy Crops along Wisconsin waterways could affect a variety of provisioning and regulating ecosystem services. We found that a switch from continuous corn production to perennial-grass production decreased annual income provisioning by 75%, although it increased annual Energy provisioning by 33%, decreased annual phosphorous loading to surface water by 29%, increased below-ground carbon sequestration by 30%, decreased annual nitrous oxide emissions by 84%, increased an index of pollinator abundance by an average of 11%, and increased an index of biocontrol potential by an average of 6%. We expressed the tradeoffs between income provisioning and other ecosystem services as benefit-cost ratios. Benefit-cost ratios averaged 12.06 GJ of additional net Energy, 0.84 kg of avoided phosphorus pollution, 18.97 Mg of sequestered carbon, and 1.99 kg of avoided nitrous oxide emissions for every $1,000 reduction in income. These ratios varied spatially, from 2- to 70-fold depending on the ecosystem service. Benefit-cost ratios for different ecosystem services were generally correlated within watersheds, suggesting the presence of hotspots – watersheds where increases in multiple ecosystem services would come at lower-than-average opportunity costs. When assessing the monetary value of ecosystem services relative to existing conservation programs and environmental markets, the overall value of enhanced services associated with adoption of perennial Energy Crops was far lower than the opportunity cost. However, when we monitized services using estimates for the social costs of pollution, the value of enhanced services far exceeded the opportunity cost. This disparity between recoverable costs and social value represents a fundamental challenge to expansion of perennial Energy Crops and sustainable agricultural landscapes.
