“…Particular analyses evaluating impacts on the environment in recent years has shown the use of biogas for production of electric energy and heat produces less greenhouse gases than the use of fossil fuels (Borjesson and Berglund 2006;Edelmann at al., 2005;Jury et al, 2010;Kimming et al, 2011). A question in this case is whether it is possible to use arable land for agricultural production as input source for production of electricity in biogas stations.…”

This paper deals with the effects of biogas stations on CO2 emissions produced within agricultural sector. In last years, owing to a positive policy of renewable energy resources a number of biogas stations in the CR has rapidly increased -actually over 350 agricultural biogas stations with the total installed power 365 MW are in operation. Concerning CO2 emissions from the agricultural sector, there is a presumption of decrease in produced emissions owing to decrease of influence of animal wastes which are processed just in the biogas stations. From the results it is obvious that CO2 emissions produced by agriculture in the CR decrease by 93.7 thousand tonnes annually. A presumption P1 that building of biogas stations will further support this trend is documented with results of a simple dynamic linear regression model. Further, elasticities of particular variables influencing the total emission from agriculture are investigated in the paper.

Lignocelluloses Feedstock Biorefinery as Petrorefinery Substitutes 349The LCF Biorefinery is a promising alternative due to the abundance and variety of available raw materials and the good position of the conversion products on the market [14]. Its profitability is also dependent on the technology employed to alter the structure of lignocellulosic biomass in order to produce high value co-products from its three main fractions i.e. cellulose, hemicellulose, and lignin [15].Currently the main feedstock for biorefineries is still based on starch. The practiced technologies in fuel ethanol industry are primarily based on the fermentation of sugars derived from starch and sugar crops, which are quite mature with little possibility of process improvements. However, using starch and sugar crops to produce ethanol also has been questioned since it draws its feedstock from a food stream. Lignocellulosic biomass is a more promising renewable resource as it is available in large quantities and does not compete with food or feed. Lignocellulosic biomass is a renewable resource that stores energy from sunlight in its chemical bonds, with great potentials for the production of affordable fuel ethanol [16,17]. Its main obstacle for a major breakthrough is the high production costs for bioenergy products.On the other hand, lignocellulosic biomass-derived products can significantly reduce green house gas emissions, compared to fossil-based products. Also, many common petrochemicals could be obtained with lower green house gas emissions from bio-based feedstocks. The maturity and economics of the conversion processes and logistics is a major challenge for lignocellulosic biomass [18].

“…Furthermore, another motivation to apply AD to treat the waste is that the producers can acquire emission reduction (CER) credits by clean development mechanism (CDM) defined in the Kyoto Protocol (International Panel on Climate Change (IPCC) Guidelines, 2006;Tong and Jaafar, 2006). Besides the environmental benefits of waste treatment (Edelmann et al, 2005), government agencies and private companies have extensively invested in AD technologies due to the increasing energy demand and environmental concerns such as global warming. Emphasis is mainly given to increase the generation of biogas, accomplish better rate of breakdown in the reactor, and subsequently minimized organic waste residue (Sonesson et al, 2000) to make the process economical.…”
