Peat products have been exported since 1930s and, therefore, peat deposit development, extraction and utilisation experience is gathered.
The main product types are fuel peat which has been used in the local market and differently prepared fen type peat with low decomposition degree which has been exported and used in local market.

Peat is an organic material that forms in the waterlogged, sterile, acidic conditions of bogs and fens.
Peat has the ability to preserve materials and this has led to some remarkable finds in peat bogs, including people buried thousands of years ago and wooden artefacts that have not survived elsewhere.
Peat bogs contribute to the welfare of all living things by 'locking up' carbon that would otherwise increase the greenhouse effect.

Peat producers in Finland often claim that it is a special form of biofuel partly because of the relatively fast released CO retake rate (if the bog is forested after use ~10–15% in 100 years) and the fact that peat bog actively binds CO on a similar levels to a growing forest.

 Bog - Wikipedia, the free encyclopedia
The term peat bog in common usage is not entirely redundant, although it would be proper to call these sphagnum bogs if the peat is composed mostly of acidophilic moss (peat moss or Sphagnum spp.).
The other major use of dried peat is as a soil amendment (sold as moss peat or sphagnum) to increase the soil's capacity to retain moisture and enrich the soil.

 Peat Filters   (Site not responding. Last check: )
Peat is partially decomposed organic material with a high water-holding capacity, large surface area, and chemical properties that make it very effective in treating wastewater.
Since wastewater leaving a peat filter system is a high-quality effluent, the soil in the trench or mound soil treatment system may be better able to accept it, and the system should last longer.
Because peat filters produce cleaner wastewater, they are useful for sites with "disturbed" (compacted, cut, or filled) soil and for environmentally sensitive areas such as shoreland areas in shallow bedrock areas, aquifer recharge areas, and wellhead protection areas.

 The Star (11-Nov-97) Vital to save peat swamps
Peat fires in the region have aroused the concern of the standing committee of the Ramsar Convention on Wetlands, an international treaty on conservation and wise use of wetlands.
Peat swamps are like giant sponges that absorb and soak up excessive rain and river water, thus controlling floods during the rainy season and releasing essential water supplies during the dry season.
And because the survival of peat swamps depends on a naturally high water level to prevent the soil from drying out, the obvious thing to do is to avoid activities which require the swamps to be reclaimed.

Peat is commonly formed from sphagnum mosses (peat moss) and sedges.
Sphagnum or peat mosses are typically the dominant plant in raised peatlands, and are the most common plant to make up peat.
Eventually, water draining from the built up peat layers of the raised bog changes the way the water flows in the surrounding wetland communities, which may lead to changes in nutrient content, acidity of the water, and the types of plants that grow in these communities.
