17th Annual Meeting of the Northern European Network for
Wood Science and Engineering

Kaunas University of Technology


About conference

Northern European Network for Wood Science and Engineering

The aim of the network is to contribute to the optimization of the resources spent individually and by society on research projects within Wood Science and Engineering in the EFI NORD area. The goal is to coordinate Northern European research in this field by maintaining a network between senior researchers, PhD students and industrial representatives.  The network targets wood and wood based products and their production and use in constructions.

Established in 2004, the Northern European Network for Wood Science & Engineering currently involves 10 partner countries. A network board consisting of one representative from each participating country are established: Erik Larnøy (Norway); Magnus Wålinder, (Sweden); Marketta Sipi (Finland); Jaan Kers (Estonia); Bruno Andersons (Latvia) Emil Engelund Thybring (Denmark), Kristina Ukvalbergiene (Lithuania), Christian Brischke (N Germany), Dan Ridley Ellis (N UK) and Bartłomiej Mazela from Poland.

The 17th Annual Meeting of the Northern European Network for Wood Science and Engineering (WSE 2021), 14-15 October 2021, Kaunas, Lithuania.

Conference themes:

  • Wood physics and mechanics
  • Wood protection and modification, durability
  • Wood engineering
  • Engineered wood products & composites
  • Application of wood-based materials

This year the focus of the conference is in wood in the future products. Besides a one day PhD course will be arranged for the PhD students and early stage researchers before the conference, 13th October.

Kaunas Railway Station is located right in the city centre, a 15-minute walk from the Old Town. Kaunas University of Technology can be reached by trolleybus lines no. 5, 7, 16 or bus lines no. 28, 39. Take the trolleybus at the stop near Railway Station and go till stop „Breslaujos str.“  (the third stop) It is aprox. 800 m walking distance from the stop „Breslaujos str.“ to the Kaunas University of Technology, Santaka Valley.
  • By Bus. There is a direct bus connection from Vilnius to Kaunas. The journey takes 1.5-2 hours. Kaunas Bus Station is close to the railway station. Kaunas University of Technology, Santaka Valley can be reached by bus line no. 3 (more information in section “Transportat in Kaunas”), departing from bus stop near Bus Station which will take you to stop “Studentų str.” It is aprox. 800 m walking distance to the Santaka Valley.

The cheapest and easiest way to travel in Kaunas is to use a public transport. All needed information regarding tickets and routed you may find on the website: https://visit.kaunas.lt/en/plan/transport/public-transport/

Kaunas has 67 trolleybus and bus routes, generally running from 4:30 AM until 10:30 PM. There are night buses on weekends and festive days.

Note: Passengers must get on the bus through the front door and validate e-tickets or buy a single-use ticket from the driver.

Tickets can be bought from the driver for 1 EUR.

Note: due to the COVID-19, you may be not able to buy a single ticket directly from the driver, but there is a possibility to use a prepaid travel card or to use a smartphone app “Žiogas” (https://kaunoziogas.lt/en/). Smartphone app is the recommended method for occasional use.
