Biochemical methane potential (BMP) of solid organic substrates: evaluation of anaerobic biodegradability using data from an international interlabor…

2011

Background: This paper describes results obtained for different participating research groups in an interlaboratory study related to biochemical methane potential (BMP). In this research work, all experimental conditions influencing the test such as inoculum, substrate characteristics and experimental conditions were investigated. The study was performed using four substrates: three positive control substrates (starch, cellulose and gelatine), and one raw biomass material (mung bean) at two different inoculum to substrate ratios (ISR). Results: The average methane yields for starch, cellulose, gelatine and mung bean at ISR of 2 and 1 were 350 ± 33, 350 ± 29, 380 ± 42, 370 ± 36 and 370 ± 35 …

Charakterystyka Palczatki Gerarda (Andropogon gerardi) jako rośliny energetycznej

2017

Celem przeprowadzonej analizy jest charakterystyka palczatki Gerarda jako rośliny energetycznej. Jest to trawa preriowa fotosyntezy typu C4, która nie jest popularnym gatunkiem w Polsce. Artykuł ma charakter przeglądowy i niniejsze opracowanie dotyczące Andropogon gerardi ma na celu zaprezentowanie możliwości jej przydatności w polskich warunkach środowiskowych jako biomasy do produkcji bioenergii na podstawie doniesień z literatury. Powolne tempo wzrostu po okresie zimowym oraz łatwość zachwaszczania plantacji powoduje, że Andropogon gerardi stanowi mało opłacalną roślinę energetyczną w warunkach polskich. Dodatkowo, zostały porównane koszty założenia plantacji w stosunku do wierzby krzewi…

Giant reed as energy crop for Southern Italy: An economic feasibility study

2016

Abstract Among renewable sources giant reed has attracted a growing interest as energy crop especially in Southern Europe, thanks to its low agronomic input requirements. This paper aimed at evaluating the economic feasibility of introduction of giant reed plantation as energy crop in the Southern Italy. In particular, an economic and financial analysis was performed by comparing giant reed (both for woodchip and chopped forage production) with traditional crops (pluriannual and annual) that are currently cultivated in the same area, such as wine grape, melon and tomato. Results showed the highest profitability of giant reed respect to other crops with current market prices. In particular, …

Energia zapomnianego topinamburu

2017

Zainteresowanie znalezieniem alternatywy dla energii z paliw kopalnych zwiększa się i kieruje uwagę na rośliny, które mogą być źródłem biomasy. Szczególnie cenne jest uprawianie roślin bioenergetycznych na glebach o mniejszej przydatności rolniczej, ugorach i terenach rekultywacyjnych. W tym względzie, wśród dużej grupy roślin, wielki potencjał ma słonecznik bulwiasty (Helianthus tuberosus L.). Jest on gatunkiem wszechstronnym, użytecznym jako surowiec w wielu gałęziach przemysłu, tradycyjna żywność dla ludzi i zwyczajowa pasza dla zwierząt. Obecnie, w Polsce bylinom tym nadal nie poświęca się wystarczającej uwagi. W artykule omówiono wybrane zagadnienia związane uprawą słonecznika bulwiast…

Bioagronomic and energy potential of Carthamus tinctorius L. in the Mediterranean area

2011

In recent years, interest in dedicated energy crops, in particular oilseed crops, in the Mediterranean area has risen. This is due both to an increase in energy demand in various sectors and the need to meet the objectives set by the European Union. The agro-energy sector may become an important economic opportunity for farms, especially when considering the use of the whole plant – the oil-rich seeds and the lignocellulosic crop residues. However, in economic terms, further study is needed in the management, quantification and subsequent use of crop residues. This research looks at the productive and energy potential of the seed and crop residues of safflower with the aim of introducing th…

Economic assessment of Eucalyptus (spp.) for biomass production as alternative crop in Southern Italy

2015

The increase in energy prices and the stagnation of sales prices of the main agricultural commodities required a rethinking of farm production strategies. Since during the last years, thanks to a series of policies aimed at promoting renewable sources it has been a rapid diffusion of lignocellulosic biomass species, this paper aimed at evaluating the economic feasibility of the introduction of eucalyptus (Eucalyptus spp.) as energy crop for farmers of Southern Italy, by comparing it with traditional crop rotations. In particular, economic analysis has been carried out in a representative case study located in the Sicilian hilly hinterland where, in 2013, it has been built a biomass plant fo…

Assessment of available potential of agro - biomass and energy crops phytomass for biofuel production in Ukraine

2017

Przedstawiono analizę publikacji wyświetlających problem wykorzystania biomasy jako odnawialnego źródła energii na Ukrainie. Wykorzystanie biomasy w systemie paliwowo -energetycznym kraju jest bardzo ważnym zadaniem. Celem badań była ocena dostępnego potencjału biomasy rolnej oraz fitomasy z upraw energetycznych do produkcji biopaliwa. Przedstawiono technikę oceny, określono potencjał i obliczono efektywność energetyczną wykorzystania biomasy na Ukrainie. Udowodniono, że wykorzystanie biomasy rolniczej do celów energetycznych w Ukrainie pozwala zmniejszyć zależność energetyczną kraju od nieodnawialnych źródeł energii.

Sulla (Hedysarum coronarium L.) leaves and stems as a potential biofuel feedstock

2014

Sulla (Hedysarum coronarium L. syn., Sulla coronaria [L.] Medik.) is a short-lived perennial legume native to the Mediterranean basin, where it is extensively grown as a 2-year forage crop playing a key role in cereal-based systems of semi-arid regions thanks to its versatility, (e.g., used for grazing, hay and silage production, and grazing associated with hay production), good-quality forage, and environmental benefits. To date, sulla has not been considered as a bioenergy crop. This research aimed to evaluate the potential of sulla biomass as a biofuel feedstock; in addition, due to the possibility to separate the leaves from the stems as suggested for alfalfa, the biomass composition wa…
