Home News About us Sea liming Lime dispenser Lime yourself Mines Contact Campaign History Sweden has soon been liming for 40 years - so has Movab. 1977 - 78, the state, via the then Swedish Board of Fisheries, allocated SEK 50 million to be used for liming during a five-year trial period. Grants were provided with 75% of the costs and could be applied for by fishing organizations, fishing clubs and municipalities. This was the start of the organized sea liming. At the start, Movab was 50% owned by Cementa and 50% by Domänverket, now Sveaskog. Liming on a smaller scale had been carried out many years earlier on the initiative of Fisheries Conservation Associations and private individuals. Svante Odén stated as early as 1967, after several years of studies, that sulfur and sulfuric acid could be transported in the atmosphere very far. Odén also stated that this had serious consequences for land and water. The acidification was detected. The Swedish Board of Fisheries' trial period was really a trial period. Minerals such as limestone, dolomite and olivine in different fractions were tested, everything from limestone flour and agricultural lime to crushed products 50 - 100 mm. Under en 20-års period var kalkstensmjölet den helt dominerande produkten. I början av 2000-talet började man gå över till grövre och dammfriare produkter för helikopterspridning. De flesta våtmarker behandlas i dag med denna produkt och även sjöarna börjar kalkas med grovkalk från helikopter. 1982 flyttades försurningsansvaret till Naturvårdsverket och anslagen ökade snabbt. 1985 spreds över 100 000 ton och från 1993 till 2004 spreds omkring 200 000 ton per år. Ett antal mer eller mindre fantasifulla spridningstekniker har passerat genom åren. Vem kommer ihåg amfibielastbilen, amfibiebandvagnen, skogsmaskinen med pontoner, Contracid-metoden där soda harvades ner i sjösedimentet, Kalkad-metoden som pumpade kalkslurry i kilometerlånga slangar från land ut till spridarbåten. För helikopterbolagen har det mer handlat om utveckling av spridarbehållare och logistik. Doserarna har utvecklats från små vattendrivna apparater (Hälleforskalkaren tex.) och en lycksökarmarknad där väldigt lite fungerade till dagens tekniskt avancerade anläggningar med precis dosering. Skogskalkningen har under tiden haft ett antal försöksperioder med skiftande resultat. I dag förekommer ingen skogs- eller fastmarkskalkning. At present, lime is spread in just over 4,500 lakes, which means that about half of the country's acidified lakes are limed. In addition, approximately 9,000 km of watercourses are covered by ongoing liming to counteract acidification damage to wildlife. The liming is carried out with about 110,000 tonnes of lime. Movab AB In order to create a long-term sustainable natural and cultural environment, we must help nature along the way, while waiting for acidifying substances to stop leaking into our waters. Sweden has soon been liming against acidification for four decades. Movab has it too!  Address Pilåkersgatan 32 A 261 41 Landskrona  Phone 0418-43 75 50  Email info@movab.nu Copyright © Movab.
