Join our Biochar Webinar Series

In October 2020, we launched an ongoing webinar series on various biochar-related topics. We have one webinar every other month and each session consists of a presentation and the possibility to ask questions and discuss. The webinars are free of charge and open to everyone, but sign-up is required. Below, you find information about our next webinar, including a link to sign-up. We record our webinars, so you can watch them again or share them with others. All of our previous webinars are available on this page.

April 16, 9-10 (CET)

Investigation of CO2 on pyrolysis of spruce wood and bark

Liang Wang, SINTEF Energy Research

Our new board member Liang introduces himself with a presentation about his work:

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.

Dr. 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. Dr. Wang’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. He works as project manager and principle researcher in several international, Nordic and National R&D projects on bioenergy, waste to energy and biofuel. He is now actively involved several projects on production and utilization biochar for different applications. He has collaboration with key industrial partners, 20 universities and institutions and 6 scientific councils worldwide. Dr. Wang is author of 87 publications indexed by Scopus with an h index of 21 based on 1403 citations.

The recording of this webinar will be uploaded soon on this page.

Piloting sludge pyrolysis – Sludge char reserach and the new pilot facility in Helsinki region

Aino Kainulainen (Helsinki Region Environmental Services Authority), February 12, 2021

In our second webinar in 2021, Aino Kainulainen presented the results of a recently completed research project on the pyrolysis of sewage sludge. The presentation includes a short virtual tour of the pilot facility that has recently been installed at HSY.

Aino Kainulainen is waste management R&D portfolio manager at the Helsinki Region Environmental Service Authority (HSY).

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.

Utilization of wastewater sludge based on superheated steam drying and pyrolysis

Henning Schmidt-Petersen (AquaGreen), December 11, 2020

The Danish company AquaGreen has – in collaboration with the Technical University of Denmark – developed small and medium scale units for steam drying and pyrolysis of various organic materials. In our second webinar, AquaGreen will introduce the technology, present key results and give examples of recent projects, both academic and commercial.

Henning Schmidt-Petersen is owner and COO of the Danish Company AquaGreen.

Biochar in Urban Green Spaces

Ann-Mari Fransson (SLU), October 23, 2020

Our first webinar gave insight into the project “Rest till Bäst”. The project considers the entire chain from feedstock, biochar production and applications. Three different feedstocks have been tested in a full scale pyrolysis plant. Biochar have been tested in different urban applications like urban tree plantation, green roofs, storm-water systems and green walls. Preliminary results will be shown. Biochar is currently used in urban tree plantations and Blue, Green, Gray solutions and the Swedish market is growing.

Ann-Mari Fransson is an associate professor at the Swedish University of Agricultural Sciences (SLU), where she focusses on sustainable urban vegetation.
