About This Conference
Plastics are ubiquitous in all aspects of modern life, including food packaging, health care and household products. There has been a massive increase in plastics production over the past several decades and there has been serious attention paid to managing plastic wastes, particularly focused on recycling/reuse. However, as of the present time it has not been feasible, either technically or economically, to achieve a fully circular system. Those plastic materials that are not processed for reuse, known as end-of-life plastics, end up in landfills or in other waste processing systems (e.g., incineration) or advanced recycling (e.g., pyrolysis) or directly disposed of in the environment. Here, micro- and nano-plastic (MNP) may be generated through incomplete decomposition of the materials. These MNP enter the air, soil and water environments where plants, animals, and humans may be exposed. The widespread occurrence of plastic globally, including in the ocean environment, has caused concern in the scientific community. Recently, there have been reports of MNP being found in drinking water supplies of major cities, raising additional concerns over potential public health risks.
As an example of focus on MNP, the US National Science Foundation (NSF) has identified the need for fundamental research in the areas of characterizing and separating plastics and decomposing them into environmentally benign or useful molecules. Ideally, any transformations would be accomplished prior to plastic reaching the environment, e.g., possible technological advances in the design of water and wastewater treatment systems may offer some viable solutions. Notably, the plastics industry is devoting considerable resources to address this issue.
This ECI conference will present timely research and technological advancements in the area of MNP in the environment while considering impacts on the ecosystem and human health. University researchers, representatives from the plastics industry, and representatives of governmental and non-governmental institutions will present critical MNP information as will policy makers, funding agencies and financial institutes. Among the focus areas that will be addressed by keynote speakers and presenters are the following:
- History and evolution of the MNP problem
- Governmental and legislative initiatives
- Characterization of environmental and human health related MNP
- Analytical methods of MNP detection
- Scientific and technological advancements to cure the problem, e.g. source reduction, water/wastewater treatment, recycle
- Prevention, e.g., packaging changes, material substitutions
The full scope of the MNP issue will be addressed, that being; characterization of MNP, cures to mitigate environmental and human health impacts, and preventive strategies going forward. Achieving a circular economy for plastics is being analyzed and debated on the global stage, but it is evident that MNP are widespread in the environment and mitigation of potential risks is a public health priority.

General Information About ECI
Engineering Conferences International (ECI) is a not-for-profit, global engineering conferences program, originally established in 1962 that provides opportunities for the exploration of problems and issues of concern to engineers and scientists from many disciplines. Over 2000 interdisciplinary conferences have been held.
The format of the conference provides morning and late afternoon or evening sessions in which major presentations are made. Poster sessions will be scheduled for evening discussion as well. Available time is included during the afternoons for ad hoc meetings, informal discussions, and/or recreation. This format is designed to enhance rapport among participants and promote dialogue on the development of the meeting. We believe the conferences have been instrumental in generating ideas and disseminating information to a greater extent than is possible through more conventional forums.
All participants are expected both to attend the entire conference and to contribute actively to the discussions. The recording/photographing of lectures and presentations is forbidden. As ECI conferences take place in an informal atmosphere, casual clothing is the usual attire.
Smoking is prohibited at ECI conferences and conference functions.
