In the business of dirty oceans: Overview of startups and entrepreneurs managing marine plastic
2021
Dijkstra, Hanna | Beukering, Pieter van | Brouwer, Roy
Plastic pollution, especially in marine environments, is a global problem that is currently inadequately managed. Solutions for marine plastic can occur through policy, behavior change and infrastructure improvements, but also through entrepreneurial ventures and technological innovations. Currently, information about these ventures and innovations is scattered and lacks coherence. This study presents the first comprehensive overview of entrepreneurial and SME led solutions for marine plastic by analyzing a database of 105 SMEs categorized into four functions: prevention, collection, transformation and monitoring. We find that small businesses are successfully commercializing goods and services to reduce the damage of plastics on the marine environment through innovative business models, with a steep growth of startups founded between 2016 and 2019. However, efforts to manage marine plastic are still underdeveloped in many areas, including microplastic management and monitoring. Practitioners, policymakers and researchers can utilize the database to identify solutions, best practices, synergies and avenues for further research, such as quantifying the environmental impacts of this industry.

Helinski, Olivia K. | Poor, Cara | Wolfand, Jordyn M.
Rivers are a major pathway for the transport of plastics into the ocean. Plastic pollution capture devices offer one way to reduce the accumulation of plastic in the environment. This paper provides a framework for selecting a device to reduce plastic pollution in freshwater, synthesizing information of forty prevailing plastic pollution capture devices. We distinguish three major components of plastic pollution technology (booms, receptacles, and watercraft vehicles) and collect details on each technology including its features, limitations, efficiency, reported costs, and maintenance requirements. A framework is developed to aid in device selection by water and waste managers, which highlights the need for a watershed assessment, an understanding of site conditions, the attainment of community buy-in, and a long-term maintenance plan. While plastic pollution capture devices can help reduce the flux of plastic waste from freshwater, management of plastic waste at the source is also needed to ultimately clean our oceans and waterways.
