Peat Production and Utilization for Horticultural and Chemical Purposes in Finland

摘要

In Finland, approximately one million cubic meters of peat is utilized annually for non-energy purposes. At the moment the main forms of peat use are horticultural and growing purposes. Nearly one half of production has been exported. The utilization of peat for environmental purposes is increasing, and the production of biological active compounds and mixtures also seems to be attractive. Before reaching the actual fuel peat layer a great deal of light, weakly decomposed surface peat has to be removed or produced. The material may be refined for soil improvement and sorbent purposes, litter, and compost. At the moment peat is used in environmental technology for sludge treatment and dewatering (filtering), as litter and sorbent for oil, liquid and odorous compounds. Production takes place alongside with fuel peat.
