Osa biopohjaisten muovien raaka-aineista tuotetaan kasvattamalla öljykasveja pelloilla. Kasvatuksen, sadon korjuun ja kuljetuksen sekä raaka-aineeksi …

Ovatko biopohjaiset muovit fossiilisista raaka-aineista valmistettuja muoveja parempia vaihtoehtoja, jos tarkastellaan asiaa ympäristövaikutusten kannalta? Read More »

Authors: Laua Wiman, Kirsi Immonen & Anna Leinonen, VTT Plastics are troubled by several sustainability challenges. Most plastics are produced from finite fossil raw materials. When they are incinerated after use, they emit greenhouse gases, and when they are not incinerated, they too often end up in the environment. Biobased plastics, made from renewable sources …

Authors (in alphabetical order): Rosa Ballardini (University of Lapland), Corinna Casi (University of Lapland), Esko Hakanen (Aalto University), Anna Leinonen (VTT), Jaakko Siltaloppi (Tampere University) and Katri Valkokari (VTT) The development and effective implementation of innovations that enable more sustainable solutions often require collaboration among multiple partners. These new forms of knowledge co-production create a …

Are we collaborating to make plastics more sustainable? Read More »

Authors: Kirsi Immonen, Anna Leinonen & Katri Valkokari VTT To foster a more sustainable and resilient plastics ecosystem, the ValueBioMat project defined three transformation pathways to describe the necessary transformation from the current plastic system towards the desired target state. Our previous blog post entitled Evolution of problem framing: How to enhance transition towards sustainable …

Authors: Esko Hakanena, Jan Holmströma, Teemu Mikolaa, Kirsi Immonenb, Jukka Niskanenc, Hannu Ilvesniemid, Corinna Casie, Kirsi Kukkof, Jouni Partanenf  Plastics are often portrayed as a problem when tackling climate change. Plastic products made from fossil raw materials also deplete non-renewable resources. Moreover, plastics are commonly incinerated at the end of their life, to avoid microplastics …

Can Plastics Be a Solution to Climate Change? Read More »

Author: Teemu Mikola In recent years, the environmental problems related to plastic materials have been gaining increasing attention. Although plastic materials deliver many benefits, such as durability, light weight, and low cost, they depend on fossil resources and create emissions and harmful waste in many stages of their value chain. To address these challenges, the …
