My research deals with energy and material applications and the feasibility of renewable energy technologies in industry. Areas of activity include pyrolysis of forest-based biomass and industrial by-products, pelleting and energy economics.

Forskning

Utilisation of Organic Sludge in Metal Industry - OSMet S2

The OSMet S2 Project aims to utilise various pulp & paper mill sludge in metallurgical applications with the goal of reducing fossil fuel dependence and associated emissions. Project partners include Swerea MEFOS AB, SSAB Merox AB, SP Processum, Volvo GTO, Outokumpu Stainless AB, The Royal Institute of Technology (KTH) and Stora Enso.

Valorisation of Organic Fines and Sewage Sludge Using Pyrolysis (OF-PYR)

The project investigates the feasibility of pyrolysis conversion for bio-based industrial feedstock to syngas and biochar production in Ireland. Partners: University of Limerick, The Irish Environmental Protection Agency, Irish Water Ltd. and the Irish Research Centre for Resource Efficiency.

Substance Flow and Transformation in Biorefinery Processes

This project investigates flows and transformation of potentially undesirable substances, heavy metals and persistent organic pollutants for example, in relevant biochemical and thermochemical processes. 

BioHub ( www )

The BioHub Project aims to serve the emerging biorefining industry in Sweden and Finland and to facilitate the transition to bioeconomy in the Botnia-Atlantica area. Methods and business models for forest terminals will be developed to increase the value of the forest-based resources. Partners include Natural Resources Institute Finland (Luke), Biofuel Region and the University of Vaasa.

Mobile Flip  (www)

The Mobile Flip Project aimed at developing and demonstrating mobile processes for the treatment of forest and agricultural based biomass resources into products and intermediates. Key technologies included pelleting, torrefaction, slow pyrolysis and carbonization. The 12 Project partners from five European countries included VTT (Finland), RISE (Sweden) and CEA (France).
