“…The NIR-based prediction models provide an indirect fast, inexpensive, and simple way to predict the BMPs of various feedstocks (Godin et al, 2015). The method has been used for estimating the BMP of meadow grasses (Raju et al, 2011), fibrous plant biomasses (Triolo et al, 2014), numerous organic substrates (Lesteur et al, 2011;Doublet et al, 2013), and Miscanthus giganteus, switch grass, spelt straw, fibre sorghum, tall fescue, and fibre corn (Godin et al, 2015). However, before the NIR is operated, many barriers need to be overcome, especially with respect to uncertainty due to the poor standard error of laboratory of the reference method (Ward, 2016).…”

“…This can be done economically within a short period of time. The chemical composition analysis is a more rapid and cheaper method than the BMP test, provided appropriate models are developed and applied (Godin et al, 2015). Rath et al (2013) has provided empirical evidence to show that the chemical composition of corn (lignin, total soluble sugars, hemicelluloses, and lipids) gives a consistent model for estimation of BMP.…”

Renewable Energy from Wildflowers—Perennial Wild Plant Mixtures as a Social‐Ecologically Sustainable Biomass Supply System

A growing bioeconomy requires increasing amounts of biomass from residues, wastes, and industrial crops for bio‐based products and bioenergy. There is much discussion about how industrial crop cultivation could promote social–ecological outcomes such as environmental protection, biodiversity conservation, climate change adaptation, food security, greenhouse gas mitigation, and landscape appearance. In Germany, maize (Zea mays L.) is the main biogas substrate source, despite being associated with problems such as erosion, biodiversity losses, an increase in wild boar populations and lowered landscape diversity. The cultivation of perennial wild plant mixtures (WPM) addresses many of these problems. Despite being less developed than maize, WPM cultivation has received notable attention among scientists in Germany over the past decade. This is mainly because WPMs clearly outperform maize in social–ecological measures, despite their methane yield performance. This review summarizes and discusses the results of 12 years of research and practice with WPMs as a social‐ecologically more benign bioenergy cropping system.

Against this backdrop, industrial crop cultivation, is far more promising. [20] There exists a wide range of industrial crops, many of which with well documented and researched cultivation techniques and utilization pathways (Table 1). [19,[22][23][24][25][26][27][28][29] Second, the potential cultivation area for industrial crops reaches from the tropics to the northern Atlantic and continental zones. [19,[30][31][32][33][34] Furthermore, industrial crop cultivation can mitigate greenhouse gas (GHG) emissions through bio sequestration [35] and through bioenergy to carbon capture and storage (BECCS) strategies. [1] This is because the below-ground fraction of the crop (the root system) remains in the soil and contributes to humus accumulation. [1,24,[36][37][38][39] In the long-term, humus accumulation even promises to rehabilitate degraded land and make it suitable for food crop cultivation again. [38,[40][41][42][43] For both algae cultivation and the use of residues from agriculture and wood industry, neither BECCS nor the recovery of degraded land is practicable. Consequently, biomass supply from industrial crops seems a more reasonable solution from a broader perspective-but how can industrial crop cultivation be expanded without compromising environmental and social needs?From an ethical perspective, industrial crop cultivation should generally not compete with other land uses such as food crop cultivation and natural successions, so that neither food security nor biodiversity conservation are threatened. [147][148][149][150][151][152][153][154] Both food security and biodiversity conservation are high on the agenda of the United Nations' sustainability development goals. [155,156] These can be realized through both land saving and land sharing approaches. [151,152] The utilization of favorable agricultural land for industrial crop cultivation should be restricted to social-ecologically sustainable land sharing concepts, e.g., wide crop rotations including both food crops and industrial crops. [23,[157][158][159][160][161][162] The land saving concept, i.e., cultivating industrial crops on unfavorable agricultural land-so-called "marginal agricultural land" [163] -thus saving the favorable agricultural land for food crop cultivation, is limited by biophysical constraints such as adverse rooting conditions and climatic conditions or economic challenges such as inconvenient field shapes and long field-farm distances. [19,25,88,89,[164][165][166][167] Additionally, the intensive (industrial) cultivation of common cash crops such as sugar cane, oil palm, rape seed, and maize often requires high off-farm inputs such as nitrogen (N) fertilizer herbicides, or insecticides. [1,153,[168][169][170] Intense usage of these A growing bioeconomy requires increasing amounts of biomass from residues, wastes, and industrial crops for bio-based products and bioenergy.
