Biocrete – Carbon negative concrete
Sverre Smeplass (NTNU), April 29th, 9-10 CEST
Each year, 1 million ton of wood waste are generated in Norway. About 300 000 ton are from the building industry, and 94 % of it are being combusted. In total, over 5 % of the woody material entering a construction site leave as waste. In addition to that, there is a noteworthy amount of chippings, sawdust and other waste from the production of woody construction materials.
“Biocrete” is a new, carbon-negative concrete, which has been developed as a cooperation between Con-Form, Skanska, Norsk biokullnettverk, Betong Øst AS (Nordic Concrete Group), Opplandske Bioenergi, NTNU and Snøhetta. Biocrete contains biochar with a carbon content of around 90 %. The biochar is produced from wood waste that would otherwise have been combusted and the production takes place at Oplandske Bioenergi, who is running Norway’s first industrial pyrolysis plant since January 2021. The plant produces biochar and heat for the district heating network.
Sverre Smeplass is chief advisor at Skanska Teknikk and professor II at NTNU.

Biochar sorbents: can we use waste to stop contamination?
Erlend Sørmo (NGI), February 25th, 2022
Erlend Sørmo from the Norwegian Geotechnical Institute (NGI) talks about the large innovation and research project that NGI is carrying out together with several academic and industrial partners, to explore the process of making biochar from different types of contaminated organic waste. The goal is to use the biochar as a sorbent to clean water, or remediate contaminated soil. In this way, troublesome waste fractions can be safely handled and turned into useful products with environmental benefit. Two important questions have to be answered however: 1) What happens to the contaminants in the pyrolysis process?, and 2) Is it at all possible to make efficient biochar sorbents from the poor quality materials that the various organic waste fractions usually are considered to be?
Helsingborg: Biochar from garden waste
Ludvig Landen (NSR), Victor Norberg (2050 Consulting), December 3rd, 2021
As part of the Interreg Öresund-Kattegat-Skagerrak project Greater Bio, you will hear about the new biochar production plant in Helsingborg which will be inaugurated in spring 2022 and the biochar market development in Sweden and Denmark. The case partners are NSR, a public waste management company in Helsingborg, 2050 Consulting and Roskilde University in cooperation with project management partners Sustainable Business Bub and Gate21. The project is running until September 2022.
Helsingborg decided in 2019 to invest in a biochar production plant as a way of turning garden waste into biochar. This will make the city greener, bring district heating to 700 houses annually, and create a local carbon sink.
Program & speakers:
- Introduction: NSR, 2050 Consulting, Roskilde University, Sustainable Business Hub
- Biochar production in Helsingborg: Ludvig Landen, R&D Director, Environmental Director at NSR

The Leader Gute Project: Biochar fertilizer in a commercial asparagus plantation
Anne and Sebastian Meyer (Waila AB), October 22nd, 2021
For our “one-year-webinar-anniversary”, Sebastian and Anne Meyer from WAILA AB talk about the soil fertility and yield related results of a field test with biochar fertilization on a commercial asparagus farm carried out in Gotland betwen 2018 and 2020.
The Swedish company WAILA AB cooperates with customers and partners across Europe. The goal is to jointly realize and optimize projects with a positive impact on the climate and/or biodiversity.
The results of this project are soon to be published in the Journal of Soil Science and Plant Nutrition, in a paper titled “Biochar-fertilizer blends – a valuable soil amendment for asparagus cultivation?”
Turning biorefinery side streams into high value carbon materials
Tomi Miikkulainen (Fifth Innovation Oy), August 27th, 2021
Our first webinar after the summer break led us once again to Finland, and we will learn about the biochar based “IKI” carbon material.
Fifth Innovation Oy is developing a biochar based material called IKI Carbon. IKI Carbon is almost pure carbon and as such, the material can be activated to function as a filter that captures impurities from air or water. The word “iki” means eternal in Finnish, and that is what the company is aiming for, restoring carbon from the atmosphere back to solid form, for good. Until now, the potential in biorefinery side streams has been largely overlooked and underutilized. What is often lacking is a meaningful way to use these leftover materials. With IKI Carbon, the company is aiming to create a big environmental impact as well as a significant new value out of these side streams.
Tomi Miikulainen is Chief Technology Officer of Fifth Innovation Oy. You can read more about IKI Carbon material here. The recording of the webinar will be uploaded soon.
OxyPower Hydrothermal Carbonization
Peter Axegård (C-Green), June 18th, 2021
In this webinar will go once again beyond the traditional “dry” pyrolysis and into hydrothermal carbonization.
Peter Axegård, CTO at C-Green, will talk about the OxyPower technology and introduce the first industrial OxyPower HTC plant. The presentation will include technical aspects, such as the opportunities to recover excess heat, as well as an overview on the properties of the hydrochar produced from different sources such as biogas digestate and wastewater sludge, and its possible uses for fertilization and carbon sequestration.
Peter Axegård has a master’s degree in engineering, a doctor of technology and an associate professor, KTH, Stockholm. He was a driving force in the elimination of chlorine gas used for bleaching pulp which resulted introduction of “dioxin free” industrial ECF bleaching. For several years he was director for pulping technology research at STFI, Stockholm. He was later responsible for biorefining at STFI / RISE . From 1996 to 2003, he was program manager for the first Swedish MISTRA project “Ecocyclic pulp mill”, which laid the foundation for e.g. The LignoBoost process for production pure kraft lignin, Cd removal from pulp mill effluent and other technologies. Since 2017 he is working in the C-Green team developing and implementing the OxyPower HTC process.
Investigation of CO2 on pyrolysis of spruce wood and bark
Liang Wang (SINTEF Energy Research), April 16, 2021
Biochar produced from pyrolysis of biomass has great potentials to be used the agricultural sector. With unique properties, use of biochar in agronomy can improve soil fertility, increase crop yields and sequestrate carbon as well. Production conditions have considerably effects on yield and property of biochar and gas and liquid by-products. In this work, the impacts of atmosphere (CO2 and N2), highest treatment temperature (HTT) and feedstock on yield of solid, liquid and gas products from pyrolysis of spruce wood and bark are evaluated, together with characteristics of the produced biochar. The findings in this study indicate that the carbon neutral biomass and CO2 could be co-utilized as feedstock and influencing carrier gas with multi benefits for biochar production, energy generation and waste management.
Liang Wang is Research Scientist at SINTEF in Trondheim, Norway and holds a doctoral degree in Thermal Energy from the Norwegian University of Science and Technology (NTNU) in Trondheim. Liang’s main research focuses are characterization and conversion of biomass and wastes using combined analytical instruments and techniques, advanced biomass carbonization technology, experimental and kinetic study of thermal conversion of biomass and charcoal and ash chemistry during biomass and waste thermal conversion.

The European Biochar Certificate
Hans-Peter Schmidt (Ithaka Institute) and Mattias Gustafsson (EcoTopic), January 14, 2021
Our first webinar in 2021 is a joint event with the Finnish Biochar Association and the Norwegian Biochar Network. We look into biochar certification. Hans-Peter Schmidt from Ithaka Institute presents the European Biochar Certificate. The EBC has been developed in order to limit the risk of using biochar, especially in agricultural applications. It is a voluntary industry standard in most of Europe, in Switzerland, it is obligatory for all biochar sold for use in agriculture. Since 2020, the EBC is the first to certify the carbon sink value of biochar which makes it a tradable asset for CO2eq offsets. In this webinar, Hans-Peter Schmidt talks about the importance of certification, the European Biochar Certificate, C-Sink markets, its requirements and how to obtain it. Mattias Gustafsson rounds off the seminar by presenting his work on adapting the EBC for the Swedish market.
Hans-Peter Schmidt is head of Ithaka Institute for carbon intelligence, an international non-profit organization and network for carbon strategies. Hans-Peter has long experience in working with biochar, especially in agricultural applications with numerous projects around the world. Especially his contributions to biochar standardization and certification as well as in the sustainable production and use of biochar have made him a stable and important part of the international biochar community. Mattias Gustafsson is co-founder of EcoTopic, a Swedish constulancy company focussing on biochar. Mattias is working actively towards developing a biochar industry and has contributed to a number of important biochar activities, among them the Stockholm biochar project.
