Thursday last week (31/10), Björn and Cecilia from the Environmental Engineering group visited Västerås and presented about waste management using insects in the seminar held in Honour of Professor Erik Dahlquist. Erik Dahlquist is Professor in Energy Technology at the Mälardalen University and has with the help of his long experience in improvements of process efficiency development co-developed the ventilation system used in the fly larvae treatment system. We got to listen to other very interesting presentations on the batteries needed for our fossil free future and we got to listen to the tale of the development of the collaborative robot YuMi at ABB. Erik finished the seminar presenting the development of energy production and usage in primely Sweden from the 1950s till today and gave a prognoses of what can be expected up till 2090. Very interesting! Erik is to be retired but will work part time as Senior Professor from the start of next year. We hope for continued great collaboration and wish Erik good luck in future and more time with family and his triathlon endeavours.
