“…The average spring-harvested RCG yield reported here, 6500 kg DW ha −1 , was not the highest yield reported for mineral soil sites in Finland. The RCG yield for mineral soils in Finland has ranged from 6400 to 7700 kg DW ha −1 (Pahkala and Pihala, 2000). However, we expect that the above-and below-ground biomass of the crop at our mineral soil site will further increase with the crop age.…”

Carbon dioxide exchange of a perennial bioenergy crop cultivation on a mineral soil

Abstract.One of the strategies to reduce carbon dioxide (CO 2 ) emissions from the energy sector is to increase the use of renewable energy sources such as bioenergy crops. Bioenergy is not necessarily carbon neutral because of greenhouse gas (GHG) emissions during biomass production, field management and transportation. The present study focuses on the cultivation of reed canary grass (RCG, Phalaris arundinacea L.), a perennial bioenergy crop, on a mineral soil. To quantify the CO 2 exchange of this RCG cultivation system, and to understand the key factors controlling its CO 2 exchange, the net ecosystem CO 2 exchange

Esitetään Jyväskylän yliopiston matemaattis-luonnontieteellisen tiedekunnan suostumuksella julkisesti tarkastettavaksi yliopiston Ylistönrinteellä salissa YAA303 syyskuun 27. päivänä 2013 kello 12.Academic dissertation to be publicly discussed, In this thesis, the methane production potential of traditional and novel energy crops was evaluated in boreal conditions. The highest methane yield per hectare was achieved with maize (4 000-9 200 m 3 CH4 ha -1 a -1 ) and the second highest with brown knapweed (2 700-6 100 m 3 CH4 ha -1 a -1 ). Recently, the most feasible energy crop, grass, produced 1 200-3 600 m 3 CH4 ha -1 a -1 . The specific methane yields of traditional and novel energy crops varied from 170-500 l kg -1 volatile solid (VS). The highest specific methane yields were obtained with maize, while the novel energy crops were at a lower range. The specific methane yields decreased in the later harvest time with maize and brown knapweed, and the specific methane yield of the grasses decreased from the 1 st to 2 nd harvests. Maize and brown knapweed produced the highest total solid (TS) yields per hectare 13-23 tTS ha -1 , which were high when compared with the TS yields of grasses (6-13 tTS ha -1 ). The feasibility of maize and brown knapweed in co-digestion with liquid cow manure, in continuously stirred tank reactors (CSTR), was evaluated. According to the CSTR runs, maize and brown knapweed are suitable feeds and have stable processes, producing the highest methane yields (organic loading rate 2 kgVS m -3 d -1 ), with maize at 259 l kgVS -1 and brown knapweed at 254 l kgVS -1 . The energy balance (input/output) of the cultivation of the grasses, maize and brown knapweed was calculated in boreal conditions, and it was better when the digestate was used as a fertilizer (1.8-4.8 %) than using chemical fertilizers (3.7-16.2 %), whose production is the most energy demanding process in cultivation. In conclusion, the methane production of maize, grasses and novel energy crops can produce high methane yields and are suitable feeds for anaerobic digestion. The cultivation managements of maize and novel energy crops for biogas production require further research.

“…RCG has been considered not only for energy purposes but also as raw material for pulp and paper production (Finell 2003;Thykesson et al 1998). The chemical composition of RCG differs depending on the harvesting time (Pahkala and Pihala 2000). The main chemical components are given in Table 1.…”

“…Most research in this area has been on wheat straw (Azizi et al 2011;Boquillon et al 2004;Frounchi et al 2007;Mo et al 2003;Wang and Sun 2002) and rice straw (Jarusombuti et al 2009;Li et al 2010), but other monocotyledon materials have also been used (Balducci et al 2008;Nikvash et al 2012;Pan et al 2006;Schopper et al 2009). Compared to wood particles, particles of monocotyledons exhibit a high heterogeneity that depends on the part of the plant from which they originate (e.g., the leaf, leaf sheath, or stem) (Finell 2003;Pahkala and Pihala 2000). The chemical composition between external and internal surface areas also differs (Wiśniewska et al 2003) because the plants have a special external surface which consists of cuticles and epicuticular waxes (Barthlott and Neinhuis 1997).…”

As a supplier to the furniture industry, the particleboard industry is searching for opportunities to reduce costs, weight, and formaldehyde emissions. One such opportunity is to use monocotyledons such as straw and hemp, as well as grasses like reed canary grass. A major problem when using reed canary grass or other monocotyledons in combination with wood is the difference in their surface properties, leading to poor reactivity and wettability with adhesives such as melamine urea formaldehyde. To this end, either the surface of the particles must be modified in some way, or different adhesives must be used. The purpose of this paper is to present adhesives, surfactants, coupling agents, and pre-treatment methods that can be used in combination with monocotyledons to improve compatibility with wood. Some of the methods have been tested on reed canary grass. The results show a wide range of strength values for the joint between wood and untreated or pre-treated reed canary grass glued with different adhesives, with and without a surfactant and a coupling agent. Isocyanate-based adhesives provided relatively strong bonds, and polyvinyl acetate, acryl, and epoxy adhesives were also effective. The most effective method was pre-treatment followed by adhesives in combination with a coupling agent.
