Pulp Paper & Logistics


METSA GROUP 19 ¨


The biomaterial, which combines pulp fibre and plastics, can be used in the electronics and automobile industries as a substitute for plastics, for example. The plant was to be initially


integrated into Metsä Group’s Rauma pulp mill with operations starting this year in 2017, with a view to building a bigger plant in Äänekoski. Other potential bioproducts include, for example, textile fibres and lignin products. Metsä Group is studying several processes and product paths and will implement them gradually. The construction of the new bioproduct mill at Äänekoski began in May 2015. That year, the focus was on construction and installation work which started at the beginning of 2016. Production trials began on February 2017. Before the bio-product mill


started up, the old pulp mill was shut down and dismantled. Metsä Group’s main partners in the construction of the bioproduct mill project were Valmet Corporation, Andritz Oy and Sweco Rakennetekniikka Oy. Valmet supplied the recovery


boiler, drying line, lime kiln, bark gasification equipment and automation systems. Andritz supplied the fibre line, wood

Key numbers of project


● More than 13,400 people in total worked at the construction site from 2015 to 2017


● Finns represented 64 per cent of the project workforce


processing plant, evaporation plant and causticising plant. Sweco was responsible for implementation planning. Around 70 per cent of the equipment was acquired from companies in Finland, and 100 per cent of the implementation planning was carried out in Finland. Regarding the equipment acquisitions, Metsä Group was responsible for the heat exchangers, electric motors, valves, pumps, equipment installation, pipes and pipe bridge, as well as electrical installation and instrumentation installation. Valmet and Andritz were responsible for the main process equipment, reactors and tanks. The construction of the bioproduct mill was implemented through client-driven subcontracting, meaning that the


construction project and various contracts were divided into smaller parts. This enabled local and small companies to take part. Overall, the degree of Finnish origin for the entire bioproduct mill project is high: more than 70 per cent. The new Äänekoski mill will also


have an impact on logistics in the region, with the Port of Helsinki agreeing to develop Vuosaari as the export harbour of the pulp produced. Vuosaari’s central role in Finnish


foreign trade flows and its good access by both land and sea were factors favouring its choice as an export harbour. Investments into the port infrastructure and the port’s role as an export harbour of Metsä Group companies created a good foundation for building a competitive solution both for Metsä Group and the society. “Vuosaari provides us with


good opportunities to develop operations that support an efficient and competitive logistics system,” said Jari Voutilainen, senior vice president for logistics at Metsä Group. “This is an important milestone in designing the export logistics solution for the investment proposal next spring. Cost-efficient and fluent logistics are key contributors when deciding on the investment.”


● After Finns, the largest groups have come Poland, Estonia, Lithuania, Croatia and Slovakia


● Around 650 contractors were working at the site each day. During the project, more than 1,000 companies worked at the site, with Finnish businesses representing 89 per cent.
