Lewandowska, Joanna Norkko, Jonna Piiparinen, Jukka Seppälä, Mari Vanharanta, Anu Vehmaa, Pasi Ylöstalo, Timo TamminenClimate change is projected to cause brownification of some coastal seas due to increased runoff of terrestrially derived organic matter. We carried out a mesocosm experiment over 15 days to test the effect of this on the planktonic ecosystem. The experiment was set up in 2.2 m3 plastic bags moored outside the Tvärminne Zoological Station at the SW coast of Finland. We used four treatments, each with three replicates: control (Contr) without any manipulation; addition of a commercially available organic carbon additive called HuminFeed (Hum; 2 mg L−1); addition of inorganic nutrients (Nutr; 5.7 µM NH4 and 0.65µM PO4); and a final treatment of combined Nutr and Hum (Nutr+Hum) additions. Water samples were taken daily, and measured variables included water transparency, organic and inorganic nutrient pools, chlorophyll a (Chla), primary and bacterial production and particle counts by flow cytometry.Peer reviewe

Unlocking circular business:A framework of barriers and drivers

Circular economy increasingly attracts the interest of business, policy makers and academia in the search for answers to sustainability challenges. While earlier studies have presented drivers that support the introduction of new business concepts for circular economy, as well as barriers that hinder the rate of innovation in the field, no systematic categorizations of such factors have been brought forward. Drawing on current literature, a framework of drivers and barriers is introduced, including seven distinct areas: environmental, economic, social, political and institutional, technological and informational, supply chain, and organizational factors. The appearance and content of these areas in practice have been examined in four case organizations by conducting thirty-six qualitative, semi-structured interviews. Empirical illustrations of the potential barriers and drivers provide managerial implications for better execution of circular business.publishedVersionPeer reviewe
