The onset of formulating strategies and policies regarding the bioeconomy can be, at least partly, attributed to the publication of the policy agenda on the bioeconomy by the Organisation for Economic Cooperation and Development in 2009. The aim of this study is to analyze selected national strategies and policies regarding the development of a bioeconomy and to clarify similarities and differences between them. The article presents a comparative overview of the strategies and policies for developing a bioeconomy in the EU, USA, Canada, Sweden, Finland, Germany and Australia. The documents analyzed are in most cases national strategies or policies. The structures and aims of these documents vary and the analysis is further complicated by the terms “bioeconomy” and “bio-based economy” having as yet no clear definition, a point which is discussed in some depth in this article. In the documents analyzed, strategies and policies on how to promote the bioeconomy are often presented based on the prerequisites of the country in focus; the need for increased research, development and demonstrations in the area is thus particularly stressed. The main emphasis is often to enhance the economy of a nation and provide new employment and business possibilities, whereas the aspects of sustainability and resource availability are addressed only to a limited extent in many of the documents.

Wastewater treatment plants (WWTPs) play a crucial role in mitigating microplastic (MP) release to the environment. In this paper, a WWTP of a textile manufacturing plant in Guangdong, China, was investigated to identify MP characteristics and the effectiveness of wastewater treatment within the plant. Laser Direct Infrared (LDIR) and Liquid Chromatography with Mass Spectrometry (LC-MS/MS) were applied to quantify both the number and the mass of the microplastics in the effluent of the textile manufacturing plant where most of the wastewater were from three printing and dyeing lines. The study further investigated the MP removal efficiency of each wastewater treatment process of the industry-owned WWTP and analysed the removal mechanism of each step, highlighting limitations in detecting and eliminating MPs. It is observed that (1) the results from LDIR and LC-MS/MS can be complementary to each other; (2) the MP concentration in the influent was 1730 n/L by number and 13.52 µg/L by mass; (3) the total removal efficiency of the WWTP were 99% by the number of MPs and 67.7% by the mass of MPs; (4) nine types of polymers have been identified in the influent, of which Polyamide (PA) was dominating; (5) hydrolysis acidification removed PA most; (6) aerobic tank, sand filter, and biological aerated filter (BAF) showed low removal efficiency; (7) coagulation and sedimentation tank had the highest removal efficiency to PET than any other processes.
