Biochemical methane potential (BMP) of six perennial energy crops cultivated at three different locations in W-Germany

摘要: To mitigate the effects of climate change, emission greenhouse gases (GHG) should be reduced. In near future, an increased use biomass for energy production will prescribed by law in European Union (EU) to achieve target reduction. One possibility energetically is its transformation into biogas. The most widely grown crop this purpose maize. Although, maize as biogas feedstock, due generous subsidies, linked several ecological and (socio)economic problems. important are soil erosion, depletion compaction, high demand subsequent leaching fertilizers/biocides, heavy workload, competition land between food production. contrast, second-generation perennial crops (PECs) feedstock can auspicious approach improve environmental footprint Therefore, we evaluated compared biochemical methane potential (BMP) five different species (cup plant, virginia mallow, tall wheatgrass, giant knotweed, reed canary grass) a wild plant mix (composite 25 parts plants) on three sites West-Germany. terms per area, wheatgrass grass exceeded productivity under favorable conditions. Hence, recommend both Central Europe or comparable climates. Additionally, other might suitable biomethanation from overall perspective, enhance (agro)biodiversity rural areas.
