Macro problems from microplastics: Toward a sustainable policy framework for managing microplastic waste in Africa

Researchers critically reviewed regulatory and policy approaches to managing microplastic pollution across African countries. They found that while environmental monitoring studies demonstrate an urgent need for action, the effectiveness of existing plastic waste policies in Africa remains poorly understood. The study proposes a sustainable policy framework tailored to the unique challenges African nations face in reducing microplastic waste generation and environmental contamination.

The Kenyan ban on plastic bags : a study of attitudes and adaptation in Nairobi

This study examined how Nairobi residents adapted to Kenya's 2017 ban on plastic bags, finding that most complied with the ban but concerns remained about enforcement consistency and availability of alternatives. The research provides insights into the social dynamics of plastic bag bans that can inform other countries considering similar policies.

Quantification, characterization, and source identification of macro- and mesoplastics in the water column of Rivers Sabaki and Tana.

Researchers sampled plastic litter in the water columns of two Kenyan rivers over a full year, quantifying plastic loads and tracing their sources using statistical analysis. The findings establish baseline data on riverine plastic flux to the Indian Ocean from East Africa and showed that rainfall significantly influenced plastic transport.

Influence of Polythene Bag Alternatives on Compliance to Environmental Legislation on Polythene Bag Ban in Rongai Sub-County, Nakuru County, Kenya

This study examined whether the availability of polythene bag alternatives influenced compliance with Kenya's plastic bag ban, finding that access to alternatives supports environmental legislation. Reducing plastic bag use is an important step in cutting the volume of plastic that eventually breaks down into microplastics.

Microplastics in Kenya's marine nearshore surface waters: Current status

Researchers collected microplastics from six locations along Kenya's marine nearshore surface waters, finding a mean concentration of 0.58 MPs per cubic meter with fragments (55%) and polypropylene (52%) as the dominant type and polymer. Malindi was identified as a hotspot for microplastic pollution, providing baseline data to support policy development in the region.

The transport and fate of marine plastics in South Africa and adjacent oceans

Researchers reviewed the transport pathways and fate of marine plastic pollution in South Africa and adjacent oceans, finding that while South Africa is considered a major plastic emitter, beach standing stocks are lower than global model predictions, suggesting much plastic is transported elsewhere or buried.

Single-use Plastic Ban and its Public Health Impacts: A Narrative Review

This review examines global policies and bans on single-use plastics, finding that they have helped reduce plastic pollution in some regions. However, enforcement and public health impacts vary widely, and more consistent international policy is needed to effectively address plastic waste.

Unraveling Macroplastic Pollution in Rural and Urban Beaches in Sarangani Bay Protected Seascape, Mindanao, Philippines

Researchers surveyed macroplastic pollution on urban and rural beaches in Sarangani Bay, Philippines, finding significantly higher plastic densities in urban areas (0.66 items/m2) compared to rural beaches (0.29 items/m2), with food packaging like polyethylene bags being the most prevalent litter type.

Toward Balancing the Budget: Surface Macro-Plastics Dominate the Mass of Particulate Pollution Stranded on Beaches

Researchers found that surface macroplastics dominate beach plastic pollution by mass on a remote South African beach, even though microfibres accounted for 99.7% of items by count. The study revealed that buried litter represents 86% of macroplastic items but only 5% of macroplastic mass, and ongoing degradation of existing plastic will increase fragment counts even without new plastic inputs.

The Role of Legislation, Regulatory Initiatives and Guidelines on the Control of Plastic Pollution

This review examines existing plastic pollution regulations globally, finding that despite many proposals and national bans, the overall effectiveness of legislation is unclear and most measures focus narrowly on marine plastics or single-use items. The authors argue that laws often lag behind science and face practical limitations given how deeply embedded plastics are in daily life.
