Tanzania has reduced plastic pollution by about 95 percent since banning plastic bags in 2019, with officials crediting the policy for cleaner cities, improved public awareness and lower environmental management costs.
Deputy Minister of State in the Vice-President’s Office for Union Affairs and Environment Reuben Kwagilwa told parliament in Dodoma on Wednesday that the nationwide ban on plastic bags has delivered “significant environmental gains” across the country.
He said the production and importation of banned plastic bags had fallen sharply since enforcement began, leading to visible reductions in waste in urban centres, waterways and coastal areas.
“The measure has contributed to a significant reduction in plastic waste across the country,” Kwagilwa said.
The policy, introduced in 2019, made it illegal to produce, import, sell or use plastic carrier bags, positioning Tanzania among a small number of African countries to implement a strict nationwide ban on single-use plastic bags.

Officials say public awareness campaigns have played a major role in the policy’s success. According to government data, awareness of the environmental impact of plastic bags has risen from below 40 percent in 2018 to more than 85 percent in 2026.
Kwagilwa said plastic waste along ocean and lake shores has fallen by around 60 percent, reducing risks to marine ecosystems and wildlife.
He also noted that municipalities are spending significantly less on clearing blocked drainage systems, with costs reportedly down by 30 to 40 percent, as plastic waste had previously been a major cause of flooding and infrastructure damage.

Environmental experts say plastic pollution has long been a major challenge in many African cities, where rapid urbanisation and limited waste management systems have contributed to widespread littering and drainage blockages.
Tanzania’s experience is being closely watched by other countries considering similar restrictions, particularly as global concern over plastic pollution continues to grow.
The government is now focusing on strengthening recycling systems to ensure long-term sustainability of the policy. Authorities plan to establish integrated waste disposal and recycling facilities in major cities, including Dar es Salaam, to further reduce environmental pressure and create economic opportunities in the waste management sector.
Officials say these initiatives are part of a broader environmental strategy aimed at improving urban resilience, protecting natural resources and promoting a circular economy approach.
While the ban has been widely praised for its environmental benefits, some industry stakeholders have previously raised concerns about the transition period for manufacturers and informal traders affected by the policy shift.
However, the government maintains that the long-term benefits outweigh the short-term disruptions, pointing to cleaner cities, reduced cleanup costs and improved public health conditions.

Tanzania’s progress adds to a growing number of African-led environmental initiatives aimed at tackling plastic pollution, particularly in coastal and tourism-dependent economies where marine litter poses economic and ecological risks.
Authorities say continued enforcement, public education and investment in recycling infrastructure will be critical to sustaining the gains achieved so far.
Tanzania’s success in reducing plastic waste follows a sweeping ban introduced in 2019 targeting single-use plastic carrier bags, one of the most visible sources of pollution in urban and coastal areas.
Before the ban, plastic bags were widely used across Tanzania for shopping and packaging, contributing to clogged drainage systems, flooding, and widespread litter in cities such as Dar es Salaam. Plastic waste also posed a growing threat to marine ecosystems along the Indian Ocean coast and to freshwater bodies such as Lake Victoria.
The government implemented one of the strictest plastic bans in Africa, prohibiting the production, importation, sale and use of plastic carrier bags, with penalties for non-compliance. The policy was backed by enforcement measures at ports of entry and public awareness campaigns encouraging citizens to switch to alternatives such as reusable cloth bags.
Tanzania’s move was part of a broader continental trend. Several African countries, including Kenya and Rwanda, have introduced similar restrictions, with Rwanda often cited as a pioneer due to its early and strictly enforced ban.
These policies reflect growing concern over plastic pollution, which has become a major environmental challenge globally. In many African cities, rapid urbanisation and limited waste management infrastructure have made plastic waste particularly difficult to control.
Plastic bags, in particular, have been identified as a key contributor to blocked drainage systems, leading to flooding during heavy rains and increasing public health risks. They also take hundreds of years to decompose, accumulating in landfills, waterways and oceans.
In response, governments have combined bans with public education campaigns to shift consumer behaviour. Tanzania’s reported increase in public awareness—from below 40 percent before the ban to over 85 percent today—highlights the importance of sustained outreach alongside regulation.
The country is now moving into a second phase of its environmental strategy, focusing on recycling and waste management. Plans to develop integrated waste disposal and recycling facilities aim to address remaining challenges and create economic opportunities in the recycling sector.
Globally, efforts to curb plastic pollution are gaining momentum, with increasing calls for circular economy approaches that reduce waste, promote reuse and improve recycling systems.
Tanzania’s experience demonstrates that strict regulation, combined with enforcement and public engagement, can deliver rapid and measurable environmental improvements—offering a potential model for other countries grappling with plastic pollution
