Production of substrate for the cultivation of mushrooms
Walkro was founded in Belgium in 1991 and has grown into one of the largest producers of substrate for the mushroom industry. Walkro produces 8,500 tons of substrate per week at its production facilities in Maasmechelen (Belgium), Blitterswijck (the Netherlands) and Wallhausen (Germany). With more than 235 employees, Walkro sources its own raw materials (mainly horse and poultry manure), produces best in class substrate and takes care of transport to mushroom growers all over the world.
At the end of 2011, Walkro was acquired by operating partner Monaghan Mushrooms, together with financial investor Gimv and Walkro’s management team. Since then, Walkro’s turnover has grown to just over EUR 75 million (2017), making Walkro one of the largest producers of mushroom substrate in the world. In December 2018, co-shareholder Monaghan buys out both Gimv and management, becoming the group’s sole shareholder.
