Welcome to Hummeltorp Sweden AB
A well managed family business for several generations
Hummeltorp Sverige AB was founded in 1973 by Bengt Otterström, who at the time manufactured his own soil types for sale. In the 1990s, the company also began to accept receiving excavated material for recycling.
100 years of innovation and development
On March 1, 2017, there was a generational change within the Otterström family and the company is now run by son Christer Otterström. Today, the company produces and sells the market's best growing garden and cultivation top soils, plant substrates, aggregates, circular ballast materials and newly developed special products.
Reception of excavated materials has increased, is more nuanced and has a world-leading recycling rate. Hummeltorp strives to be at the forefront of its genre with the greatest focus on recycling all excavated materials 100% and thereby benefiting our nature and future with a natural climate-smart cycle.
But our history goes back even further than that. Join us on our journey!
