Lassila & Tikanoja Plc is a Finland-based circular economy company specializing in environmental management and support services. Founded in 1905 in Vaasa by Josef Lassila and Frithjof Tikanoja as a wholesale business, it has evolved through strategic transformations, particularly in the early 1990s, into a leader in waste management, recycling, and sustainable operations across Finland and Sweden. The company operates through key segments including Environmental Services, Industrial Services, and provides facility services, offering comprehensive solutions such as hazardous waste treatment, remediation, industrial process cleaning, water treatment, sewer maintenance, property technology, and energy management to extend asset lifecycles. With approximately 2,300 employees, Lassila & Tikanoja Plc manages around one million metric tonnes of waste annually, leveraging extensive infrastructure like 1,200 vehicles and 174,000 work sites to deliver nationwide services and economies of scale. Following a partial demerger effective December 31, 2025, it focuses exclusively on circular economy operations, transforming waste streams into valuable raw materials and supporting societal infrastructure for material reuse. This positions it as a market leader in Finland's fragmented waste management sector, addressing megatrends in sustainability.
