production) should be doubled, because a gas cleaning module and compression plant will be<br />
added. There is no data available on the producers who make motor fuels from the landfill gas,<br />
but the data of pilot plant (in the Jyväskylä landfill) cannot be used for the comparison.<br />
Based on some BGP feasibility calculations by the authors, it can be stated that considering<br />
the energy prices and state subsidized schemes in Estonia at the level of 2007, it would be<br />
feasible to build the biogas fired CHP plants at larger landfills (burning landfill gas) and at<br />
larger wastewater treatment plants (based on the sludge) if the gained energy (heat, electricity)<br />
can be completely used (power network, DH network, production processes, etc.).<br />
The production of energy from the agricultural manure will also be feasible when the share of<br />
methane in the gained biogas exceeds 55% (it can often be reached only with adding fats or<br />
corn flour, e.g.) and with the precondition that the total amount of energy can be sold or used<br />
effectively in the site (e.g., a subsidiary to BGP where energy is used in the production<br />
process). Also the benefit from environmental protection and improvement of the social<br />
climate in the region should be considered indirectly as a part of feasibility.<br />
There is no information about any profound studies on the BGP based on herbaceous biomass<br />
as the main raw material in Estonia up to now, because the necessary initial data is not<br />
available, there are no concrete developers and sites known. Anyway, a herbaceous biomass<br />
based BGP that operates in the complex with CHP (built within 10 km radius) should have<br />
the electrical capacity of at least 500 kW el , and considering the yield of Estonian fields, there<br />
should be at least 400-500 ha of field. The feasibility of building these BGPs depends highly<br />
on the grain and fodder prices in the world market. When considering the prices and state<br />
subsidies in 2007, construction of herbaceous biomass based BGPs will not be apparently<br />
feasible.<br />
Production potential of biofuels for transport: acceptable technological solutions,<br />
capacities and sites<br />
Up to now the high production cost of biofuels has remained a critical barrier for their wider<br />
use. The competitiveness of biofuels will be improved with the advance of the oil price and<br />
that of other fossil fuels. So far the competitiveness of biofuel is depending on the concessions<br />
and subsidies provided.<br />
In 2003 the Biofuels Directive was adopted in the European Union where a goal was set for<br />
biofuels and other renewable fuels to reach the indicative share of 5.75% (calculated by the<br />
energy content of fuels) among the diesel and petrol fuels available for the transport in the<br />
market to 2010. It will remain for a member state to decide either the biofuel is exported or<br />
produced on site. The directive set an advisory, not a mandatory target.<br />

According to the EU Directive 2003/30/EC, in 2010 the amount of used biofuels must replace<br />
54 thousand tons of fossil fuels in Estonia, or due to the lower energy content of biofuel, 25<br />
thousand tons of bioethanol and 42 thousand tons of biodiesel has to be marketed.<br />
