  • Patent number: 7507265
    Abstract: A method is disclosed for producing horticultural or fuel peat, in which the peat is removed from a bog, the removed peat is transferred from the bog to a drying field a distance away, in which the moved peat is dried, mainly by exploiting direct solar energy, so that the peat dries due to the effect of the solar radiation and the wind, after drying, the peat is moved from the drying location to further use or storage. The drying field is a special surfaced field, essentially impermeable to water, created for drying, and the peat is spread on the field as a thin 1-15 cm layer of a high-consistency mass, with a solids content of 8-30%.

  • Patent number: 5905039
    Abstract: A logistic method for transporting and handling materials in a tunnel composting plant, as well as the plant itself includes bringing materials for tunnel composting to the plant. The materials are unloaded into intermediate collection points and compostable material is treated from the materials brought also according to the current recipe. The composting materials are transferred to a composting tunnel that is free at the time, and after composting the composted material is transferred from the composting tunnel to a heap of finished material at its own collection point. Composted material is transported from the heap of finished material to the desired point of use. According to the method, essentially all of the handling of all the materials at the plant is carried out using a wheeled loader, equipped with a mixing and crushing bucket.
