Abstract: Sheet of insulating plates comprising successively placed lamellae of insulating plates attached to each other at their edge side which is cross directional in relation to the longitudinal direction of the sheet of insulating plates, alternately at the upper corners and lower corners of the cross directional edge sides, whereby thus formed uniform sheet of insulating plates comprising several lamellae of insulating plates can be folded into accordion-like folded stack of lamellae of insulating plates and unfolded again into a uniform sheet of insulating plates, which sheet of insulating plates has an upper surface and a lower surface. The upper surface of the sheet of insulating plates comprises a surface layer which is arranged in the longitudinal direction of the sheet of insulating plates alternately attached to and detached from the lamellae of the insulating plates in groups of two successive lamellae of insulating plates.

Abstract: The present invention relates to the fields of industrial biotechnology, renewable raw materials and production of organic acids. Specifically, the invention relates to a method of producing an organic acid or a salt thereof. Still, the present invention relates to a mixture comprising legume molasses and calcium hydroxide or a mixture obtained by combining a carbon substrate composition comprising legume molasses and an aqueous suspension comprising calcium hydroxide, for producing an organic acid or a salt thereof by a microorganism, and use of said mixture for producing an organic acid or a salt thereof. Still further, the present invention relates to a method of producing one or more products selected from the group consisting of polymers, polyesters and polylactic acids.

Abstract: A solar panel system wherein solar panels are arranged on the soil, substantially in parallel with the ground surface, and at least some interspaces between the solar panels are provided with a board or boards of thermal insulation material substantially in parallel with the ground surface. A cooling pipework of the solar panel system is arranged underneath the solar panels and the boards of thermal insulation material in the soil. A cooling pipework is further arranged in at least some of the boards of thermal insulation material on the ground surface, and/or is connected to heat distribution boards on top of the boards of thermal insulation material on the ground surface.

Abstract: A method for recycling polystyrene in a dissolution recycling process, in which method 1,3-dioxolane or isoamyl acetate is used as a solvent for dissolving polystyrene.

Abstract: A thermal insulation plate (1), which is manufactured from cellular plastic, and the upper surface of which comprises grooves (5a, 5b), which are arranged in two directions over the area of the entire surface. The thermal insulation plate comprises at least in part of the groove (5a, 5b) intersections a spacer (6, 6a, 6b) for installing reinforcement, which is formed from thermal insulation material as a fixed part of the thermal insulation plate.
