Systeeminen muutos kohti muovin kestävää valmistusta ja käyttöä edellyttää uudentyyppisten materiaaliratkaisujen kehittämistä sekä arvoverkoston roolien uudistamista. Uusien ratkaisujen syntymistä voidaan tukea varmistamalla, että yhteiskunnallinen ja taloudellinen ohjaus tukevat toinen toisiaan. Systeemisiä ongelmia ratkaistaan kokeilemalla, vuorovaikutuksella ja epävarmuutta paremmin ymmärtämällä, siksi tarvitaan ekosysteemitason tarkastelua muutoksen ajureista. ValueBioMat projektin tutkijat Jaakko Siltaloppi Aalto-yliopistosta ja Markus Jähi VTT:ltä …

Authors: Frans Silvenius, Marjatta Vahvaselkä and Hannu Ilvesniemi / Luke When performing a life-cycle assessment (LCA), data is collected from all relevant parts of different production systems related to the whole value chain covering the raw material, manufacturing, transport and waste management phases. This essential and time-consuming task can be done by using different data …

Authors: Niklas Kretzschmar, Sergei Chekurov and Jouni Partanen / Aalto University Even though additive manufacturing (AM), also known as industrial 3D printing, is already there for some decades facilitating the manufacture of new design variations and legacy parts, it is still considered as a set of new production technologies. For numerous technical reasons, AM hasn’t …

Authors: Katri Valkokari , Peter Ylen (VTT) & Rosa Ballardini and Juha Vesala (University of Lapland) A transition towards renewable and circular plastic ecosystems is a systemic challenge. In this regard, there is an obvious need to find the appropriate bundle of policy measures, incentives and regulation instruments to enhance the transition to a sustainable and …

Authors: Jukka Seppälä, Laura Äkräs, Kasper Dienel / Aalto University Plastics are central in our modern life and have plenty of good properties that advance sustainability. However, they have recently received a lot of negative and contradictory attention. But what materials are considered as plastics? This has been one of the key questions when preparing …

Authors: Satu Salminen, Jaakko Siltaloppi / Aalto University The transition from fossil-based to bio- and circular economy is emerging as one of the major necessary societal transitions of the coming decades. While bio-based and recycled plastics are increasingly perceived as opening future business opportunities, as we have identified in the ValueBioMat project, in practice only …

Author: Lars Vilen, Jaakko Siltaloppi / Aalto University The current linear economy model of plastics production and consumption entails a number of issues, including the leakage of plastics waste into the environment. Certainly the most salient issue from a political perspective, the environmental problems with plastics have induced a variety of political actions especially in …

Authors: Hannu Ilvesniemi and Frans Silvenius / Luke The carbon-cycle of bio-based plastics occurs mainly in natural carbon balance: the raw materials are mainly plant-based products, and the carbon content of them has been taken from atmosphere, and when they decompose, the carbon taken from atmosphere returns back. The carbon balance is different when the …
