Welcome to Wood Chemistry and Pulp Technology

Head of division

Professor Monica Ek, head of Wood Chemistry and Pulp Technology.

Pulp technology deals with the processes and techniques used to expose the fibers from wood. The fibers are mainly used as raw material for pulp and paper, but also other products such as the pharmaceutical industry. Wood chemistry investigate the chemical reactions that occur in these steps, as well as the morphological and chemical structure of the fibers of wood and products.


Water filters for refugee camps

On 21 March 2017, our division developed a portable, effective, and eco-friendly filter to deal with the drinking water safety issue in the tons of refugee camps all over the world. The wood fiber based filter can capture and kill the bacteria efficiently by a simple shake in the water, and the anti-bacteria technique has no problem with toxic chemical leaching compared with the conventional water purification methods.

1st Swedish Lignin Workshop 2017

During 16-17 March 2017, we organized the 1st Swedish Workshop on Lignin Chemistry, Processing and Valorization at RISE, Stockholm. The idea is to create a national forum for the young researchers and supervisors working within area of Lignin Chemistry research,and provide a platform to interact and cooperate. Contact: Olena Sevastyanova ( olena@kth.se) or Monica Ek ( monicaek@kth.se).


During 7-9 March 2017, our division and COST-European Cooperation in Science and Technology organized the COST Action FP1205 Conference on Cellulosic material properties and industrial potential at KTH, Stockholm, Sweden. The topic involved in Dissolution and regeneration of cellulose, Science and uses of nanocellulose,& Cellulose foams and films.

Best Poster winners in COST ACTION CONFERENCE 2017

Tiinamari Seppänen, a master student at our division, won the 1st Best Poster Prize in COST ACTION CONFERENCE 2017. Congratulations!

Biofiber Chemistry course study tour 2016

On 13 December 2016, our division organized a study tour of Biofiber Chemistry course, and we hoped the students can have the opportunity to learn about forest industry-one of Sweden’s most important base industries. 

Study visit-Tumba Papermill Museum

On 6 December 2016, we organised a study tour in Tumba Papermill Museum. Students had the chance to know about the traditional papermaking process and development of the Swedish forest industry.

Top Prize in the KTH Materials Day 2016

On 11 November 2016, Anna Ottenhall(PhD student) got the Top Prize(10,000 kr) in the PhD student pitch competition at KTH Materials Day 2016 as a result of her best performance to introduce her project-drinking water sterilization by antibacterial fibers.

 Best Poster Award in the Guangzhou Papermaking Conference 2016

On 9 November 2016,Tianxiao Huang(PhD student) won the Best Poster Award in the 5th International Symposium on Papermaking .He evaluated Hydrophobic Coating on Textile by Bark Extractives, which explored the value-added application of a side stream product from forest industry.

2nd place in Young Researchers Competition 

On 10 October 2016, Anna Ottenhall(PhD student)got the 2nd place in the Young Researchers Pitch Competition during the Marcus Wallenberg Prize 2016 Conference. She introduced an easy and cheap way to sterilize drinking water using antibacterial fibers. Learn more-abstract of her poster

Our novel nanocrystalline cellulose technique won the Entrepreneur Program

On 14 October 2016, researchers at our division won the KTH's new accelerator program for entrepreneurs - Bicky Chakraborty Entrepreneur Program, because we have developed a new process for the inexpensive and efficient production of nanocrystalline cellulose (NCC), a renewable material with application areas as reinforcement, barriers or filler in package or automotive industries. This technique contributes to a startup of the company Fine Cell . Team members: Dongfang Li, Jonathan Henschen and Monica Ek.

American Chemical Society Conference

We participated in the 251st ACS National Meeting & Exposition in San Diego, California during March 13-17, 2016.Nicola Giummarella and Selda Aminzadeh presented their projects about lignin from wood resources. Besides, Jonatan Henschen showed his research results about anti bateria materials and demonstrated a poster “Water purification using eco-friendly antibacterial fibres”. Monica made two presentations about recent projects “Biointeractive Fibers with Antibacterial properties” and “WOBAMA Wood Based Materials”.

New PhD

On 18th March 2016, Ran BI defended her PhD thesis(Lignocellulose Biodegradation by Soil Microorganisms). Congratulations!
