Effective Waste Management for a Healthier Sao Tome and Príncipe

Sao Tome and Príncipe, a parliamentary republic located in the Gulf of Guinea, is known for its breathtaking rainforests, pristine beaches, and rich cultural heritage. However, the island nation also faces challenges in managing its waste effectively. Improper waste management practices not only impact environmental health but also pose significant health risks to the local population. To address these challenges, effective waste management is essential for creating a healthier Sao Tome and Príncipe and safeguarding the island’s natural beauty.
