The international cooperation project "electricity-driven low energy and chemical input technology for accelerated bioremediation" (abridged as "ELECTRA") is jointly supported by National Nature Science Foundation of China (NSFC) and European Commission (EC). The ELECTRA consortium consists of 5 research institutions and universities from China and 17 European research institutions and universities, as well as high-tech companies of EC countries. ELECTRA focuses on researches of biodegradation of emerging organic compounds (EOCs) and novel environmental biotechnologies of low-energy and low-chemical inputs. The project has been successfully operated for 2 years, and has made important progresses in obtaining EOCs-degrading microbes, developing weak-electricity-accelerated bioremediation, and 3D-printing techniques for microbial consortium. The ELECTRA has promoted collaborations among the Chinese and European scientists. In the future, ELECTRA will overcome the negative impact of the COVID-19 pandemic and fulfill the scientific objectives through strengthening the international collaboration.

Humanity shares the common interest to protect the environment and to maintain a healthy global ecosystem. International collaboration is key in this context, to advance the necessary science and technology. The National Science Foundation of China (NSFC) and European Commission (EC) have agreed to collaborate in innovative knowledge and technology in the field of bioremediation of polluted environments and biodegradation of plastics. In this context, projects on bioremediation of soils, wastewater and sediment matrices and on microbial degradation of plastics were supported. This special issue aimed to introduce these projects and their progresses in the related fields. In total, 23 papers have been collected in this issue, covering both fundamental and applied researches.
