Ghana's next Environment Minister backs CSIR push for plant-based plastics from cassava and hemp

Ghana's incoming Environment, Science and Technology Minister has thrown her weight behind a bold plan to harness local agricultural resources in the fight against plastic pollution. During her parliamentary vetting on Thursday, Dr Zanetor Agyeman-Rawlings proposed channelling increased government funding to the Council for Scientific and Industrial Research (CSIR) to develop biodegradable materials from readily available crops including cassava and hemp, positioning Ghana to turn a persistent environmental problem into an innovation opportunity.

The proposal signals a potential shift in how the country tackles its mounting plastic waste crisis—moving beyond disposal and regulation towards domestically driven technological solutions. With landfills overwhelmed and plastic pollution affecting waterways, agriculture and public health, the initiative to invest in plant-based alternatives represents a forward-thinking approach that could create economic value whilst addressing environmental degradation.

Why It Matters for Ghana

Plastic waste has become one of Ghana's most pressing environmental challenges. Cities and towns struggle with disposal, waterways are choked with non-biodegradable waste, and informal recycling sectors operate with minimal oversight or safety standards. A successful domestic research programme could yield multiple benefits: reducing Ghana's dependence on imported plastic materials, creating new industries and jobs in bioplastics manufacturing, and establishing the country as a regional leader in sustainable material innovation.

Critically, developing these alternatives from crops like cassava—which Ghana already produces in significant quantities—could integrate farmers into a new value chain, adding income diversification beyond traditional food production. This aligns with broader goals of agricultural transformation and climate resilience.

Dr Agyeman-Rawlings also emphasised the need for stronger environmental safeguards at landfills, insisting that non-permeable bases be mandatory to prevent hazardous substances and toxic chemicals from leaching into soil and groundwater. This reinforces growing international standards and protects Ghana's fragile water resources and agricultural soils from contamination.

A Whole-of-Society Approach

Beyond laboratory innovation, the minister-designate stressed that tackling plastic pollution requires coordination across government, communities and the private sector. This reflects the reality that no single intervention—whether research funding, landfill standards or individual behaviour change—can solve the problem in isolation.

• Research investment: CSIR funding for biodegradable cassava and hemp-based plastics
• Infrastructure standards: Mandatory non-permeable landfill bases to prevent soil and water contamination
• Stakeholder engagement: Coordinated national response involving government, communities and private sector

The private sector's role will be crucial—from manufacturing companies willing to adopt alternatives, to retailers redesigning packaging and supply chains. Communities must support waste segregation and responsible disposal, whilst government provides policy stability and investment.

Next Steps and Challenges

For this vision to succeed, several hurdles must be cleared. CSIR will need sustained, adequate funding and political commitment beyond a single term. Research timelines for scaling biodegradable materials to commercial viability typically span years. Consumer acceptance and price competitiveness with conventional plastics remain open questions. And enforcement of landfill standards across Ghana's many disposal sites will require resources and coordination.

Nevertheless, Dr Agyeman-Rawlings's proposals indicate a ministry willing to move beyond reactive crisis management towards proactive, innovation-led solutions. If approved by Parliament, her tenure offers an opportunity to demonstrate whether Ghana can transform its environmental challenges into competitive advantage through science and local ingenuity.
