What You'll Learn
Reduce plastic use
To reduce plastic use and prevent plastic pollution in our rivers, it is essential to understand the sources and impacts of plastic pollution. Rivers are natural pathways that carry nutrients and sediments from the land to the oceans, and they play a significant role in transporting plastic waste into the marine environment. According to research, a significant portion of the plastic found in rivers comes from mismanaged plastic waste upstream, as well as urban and stormwater runoff, littering, and industrial activities.
One of the most effective ways to reduce plastic pollution in rivers is to minimise the use of single-use plastics. Single-use items such as plastic bags, plastic wrap, disposable cutlery, straws, and coffee cup lids contribute significantly to plastic waste. By choosing reusable alternatives, we can significantly reduce the amount of plastic that ends up in our rivers and oceans. For example, instead of using plastic bags, opt for reusable cloth bags or baskets when shopping. Refuse plastic straws and disposable coffee cups, and bring your own reusable water bottles and food containers. These simple choices can have a significant impact in reducing plastic pollution.
Another way to reduce plastic use is to support legislation and initiatives that aim to reduce plastic production and improve waste management. At the international level, the United Nations has enacted a global plastics treaty, and organisations like IUCN support ambitious reductions in plastic production and the phasing out of harmful products and chemicals. At the national and local levels, advocate for policies that promote extended producer responsibility (EPR) legislation, making plastic producers and distributors responsible for their products' end-of-life disposal and packaging. Support initiatives that focus on urban coastal areas, implementing improved litter collection, street litter removal, and river cleanup programmes to prevent plastic waste from reaching the oceans.
In addition to legislative efforts, it is crucial to support circular economy solutions. This involves increasing the circularity of supply and value chains, encouraging reuse and refill options, and investing in infrastructure that supports the full lifecycle of plastics. By extending the life of plastic products and materials, we can reduce the demand for new plastic production and minimise waste. Individuals can contribute by choosing second-hand or refurbished items whenever possible and supporting businesses that offer repair and refurbishment services.
Lastly, education and awareness are key components of reducing plastic use. Learning about the impacts of plastic pollution on ecosystems and human health can motivate individuals to make more sustainable choices. Share information about plastic pollution with your community, friends, and family, and encourage others to reduce their plastic consumption and properly manage their waste. By working together and making conscious choices, we can significantly reduce plastic pollution in our rivers and protect our environment for future generations.

Reduce plastic waste
Plastic pollution is a pressing issue, threatening wildlife, ecosystems, and human health. To reduce plastic waste and its harmful impact on our rivers, several measures can be implemented:
Reduce Plastic Consumption
The first step is to reduce plastic use. This involves a shift away from single-use plastic items such as bags, bottles, straws, and disposable cutlery. Opt for reusable alternatives whenever possible. Governments and industries should work together to reduce plastic production and promote sustainable practices.
Proper Waste Management
Mismanaged plastic waste is a significant contributor to river pollution. Proper waste management systems are essential, including improved litter collection, street litter removal, and prevention. This involves investing in infrastructure and services to ensure effective waste collection and disposal.
River Cleanups
Focusing on urban coastal areas and river cleanups can be highly effective in reducing plastic waste entering our rivers and oceans. Technologies such as The Ocean Cleanup's Interceptors can be deployed to extract waste from rivers and prevent it from flowing into the oceans. These interventions can be tailored to specific rivers, considering factors like river width, depth, flow speed, and debris composition.
Public Awareness and Education
Raising public awareness about the impacts of plastic pollution is crucial. Educating communities about proper waste disposal, the environmental consequences of plastic waste, and the importance of reducing plastic consumption can drive behavioural changes. Encouraging participation in river cleanup initiatives and promoting sustainable alternatives can also help reduce plastic waste.
Policy Changes and Global Cooperation
Addressing plastic pollution requires policy changes at the national and international levels. A global plastics treaty can help reduce plastic production, phase out harmful subsidies, and adopt strong national plans for plastic waste reduction. Policies should also encourage circular economy solutions, such as reuse and refill programs, to minimize plastic waste generation.
By implementing these measures, we can significantly reduce plastic waste and its impact on our rivers, protecting ecosystems, wildlife, and human health for future generations.

Improve litter collection
Improving litter collection is a critical step in reducing plastic pollution in our rivers and, subsequently, our oceans. Rivers are a significant pathway for debris and litter from human communities to ocean systems. Thus, implementing effective litter collection strategies can substantially reduce plastic pollution in these water bodies.
One approach to improving litter collection is to focus on urban coastal areas. Small urban rivers are major sources of riverine litter, particularly macroplastics, which eventually reach the ocean. By enhancing litter collection efforts, street litter removal, and river cleanups in these areas, the amount of plastic waste entering oceans can be significantly reduced. This strategy is supported by studies that identified small urban rivers as significant contributors to river-transported plastic pollution.
Additionally, addressing litter in freshwater systems is vital. Data collection and research on plastic pollution in freshwater environments, such as rivers and lakes, can help improve understanding and management of the issue. For instance, the consistent methodology developed by Rech et al. (2014) and applied in Chilean rivers can enhance knowledge about the degradation of litter in riverine systems. Furthermore, initiatives like the Chilean citizen science program, Científicos de la Basura, which involves teachers and schoolchildren in investigating environmental litter pollution, can be replicated to raise awareness and encourage community participation in litter collection efforts.
Moreover, implementing waste management infrastructures and recovery systems can help prevent the emission of riverine litter into the sea. For instance, giant bar screens placed over rivers can collect litter from the water column. While such systems may not entirely eliminate riverine litter, they can significantly reduce the amount bypassing into the sea during heavy rainfall.
Finally, it is essential to recognize that litter dynamics in rivers are complex and influenced by various factors, including rainfall and geographic location. Therefore, a combination of manual litter collections on riverbanks and the use of passive technical devices can help address the issue more effectively.
