Peat belongs to nonrenewable natural resources, and its commercial production involves some environmental problems. Peat mining and use as a source of fuel began on the European continent as early as the 17th century. Peatland development is only possible after preliminary drainage of bogs, and the steady decline in the area of such bogs conditions rising environmental concerns. Peat mining to be efficient also needs that peat beds are sufficiently thick. The lack of macro- and micro-elements required for the successful cropping on mined-out peatlands dictates introduction of these elements together with mineral fertilizes, which increases the peat production cost and aggravates the ecological impact. For this reason, it is most promising to use minedout peatlands for the forest regeneration under condition of the minimized ecological impact, including preliminary treatment of the peatlands and their further maintenance. The ranges of the effective use of peatlands dropped-out of commercial operation are assessed. It is emphasized that production of biomass for the power-generating purposes is the most effective trend. The environmental benefits of this approach include the efficient usability and biological reclamation ability of low-productive mined-out peatlands; reduction in greenhouse gases emission; maintenance of species diversity in the mined-out peatlands. Its shown that biological reclamation of mined-out peatland is possible with both maintenance of natural bog plant communities and creation of manmade short-cycle plantations of tree crops. It is found that production of renewable biomass with further pelletizing is an economically efficient trend both in using natural plant communities and in creation of manmade osier plantations.
