“…Today, maize is the main co-substrate for the biogas plant of the EPH but there is already a notable share of cup plant as biogas substrate. Cup plant has only recently been discovered as an energy crop for biogas production, 72,73,96,97,[102][103][104][105] and long-term data on its performance are still missing. The large-scale use of cup plant at EPH is somewhat unexplored.…”

Excessive cultivation of maize (Zea mays L.) as a biogas substrate has fired debate about potential land‐use change effects of bioenergy cropping systems. Cup plant ( Silphium perfoliatum L.) is a perennial biogas crop that provides more environmental services than maize. This study investigated (i) how to replace maize with cup plant as a biogas substrate in a large‐scale biogas plant located in southwest Germany, and (ii) how to optimize the energy and material cycles of such a biogas plant given the new feedstock. The biogas plant produces 1000 m3 biogas per hour with plans for it to be combined with a large dairy farm (1000 dairy units). It was found that the substitution of maize with cup plant as a biogas substrate results in a methane yield reduction of 10% to 20% due to lower biomass yields. However, there exists a strong potential to increase both biomass yields and biogas substrate quality of cup plant by optimizing establishment procedures and better genotypes. Furthermore, cup plant provides food and shelter for open land animals, including birds and insects, and could hence be a suitable alternative to maize for large biogas plants, being more environmentally beneficial. Extracting proteins from cup‐plant biomass could also help replace soy with locally produced protein for feeding cattle. Hydrothermal carbonization is a promising tool for closing nutrient cycles and for extracting phosphate from digestate, but more research is needed before it can be put into practice. © 2020 The Authors.

“…For pellet production, the milled herbaceous energy plants were granulated in a small-capacity (100 t ha -1 -120 kg h -1 ) granulator with a horizontal granulator matrix. The diameter of the pellets was 6 mm [18]. The mill was granulated in the traditional way: before the mill entered the granulator, the mill was mixed thoroughly to achieve homogeneity.…”

Three unconventional herbaceous energy plants -sida (Sida hermaphrodita Rusby), elephant grass (Miscanthus giganteus) and reed canary grass (Phalaris arundinacea) -were grown and investigated in the experimental fields of Aleksandras Stulginskis University, and the technical means of plant preparation and usage for energy purposes were investigated. The physical-mechanical characteristics (moisture content, density, flow angles) of chopped and milled unconventional energy plants were investigated. These characteristics are required to project and choose the supply, transportation and storage equipment. In evaluating the quality of plant chopping and milling, the fractional compositions of reed canary grass, sida and elephant grass chaff as well as the mill were determined. The largest chaff fraction was found in a sieve with 8-mm diameter holes (from 52.0 to 62.7%), and the largest mill fraction was found in a sieve with 0.5-and 0.63-mm diameter holes (from 37.6 to 46.4%). The pellet moisture content was sufficiently low and varied from 6.7% to 9.6%. The highest density was determined in reed canary grass pellets (1035.1±63.9 kg m -3 DM), and the lowest density was in elephant grass pellets (653.6±67.1 kg m -3 DM). The emission of harmful gases was determined when various unconventional energy plants were burned. The highest concentration of carbon monoxide (CO) was observed when burning elephant grass (2294.7 ppm), and the smallest concentration of CO was observed when burning reed canary grass (905.2 ppm). The most carbon dioxide was detected when burning sida (7.9%), and the smallest when burning elephant grass (5.2%). The nitrogen oxide emissions differed only insignificantly; the values ranged from 176.2 ppm (Reed canary grass) to 216.1 ppm (Elephant grass). a prime cost of 0.12 EUR/kg. When energetic grasses were dried using dispergation, the primary cost increases to 0.13 EUR/kg.

The research investigations with a short rotation energy plant -black poplar (Populus Nigra L.) have been carried out at the Institute of Agricultural Engineering and Safety of Vytautas Magnus University. A chopper with a conical screw was selected for the energy plants chopping. This type of woody plant choppers is the most appropriate to use because these choppers cut plants by a conical screw with a sharpened outer edge and, therefore, can cut long enough and high quality chaff. The biometric characteristics of black poplar stems and thephysical-mechanical characteristics of the plant chaff were assessed: moisture content, bulk destiny, fall and natural crumble angles, chopped mass fractional composition, ash content and calorific value. The determined bulk destiny of the plant chaff varied from 112.3 to 218.5 kg·m -3 DM (dry matter). Black poplar chopping quality, characterized by fractional composition, was also determined ,. It was estimated that the largest part of fraction was concentrated on the sieves with a diameter of 8 and 16 mm holes -from 53.9 % to 71.8 %, and very small amount of dust was formed -from 0.04-0.09 %. The research results of the black poplar ash content and calorific value show that the ash content was relatively low and reached only 2.5 %. It shows that the chaff of black poplar burns relatively well and, in comparison with other sorts of energy plants, the determined lower calorific value of black poplar chaff dry mass is relatively high -18.5 MJ·kg -1 . The presented research results show that the usage of black poplar for biofuel is justified very well.
