Case Study: From Waste to Quality Education – How an Educational Institution Transformed into a Circular Campus with Zero Waste Technology
Executive Summary
The International School of Educational Excellence (ISEE), located in Bamenda, North West Cameroon, leveraged the Green Waste Center (GWC) solution to transform into a circular campus. These efforts have not only positioned ISEE as a leader in sustainable education but have also provided the school with the tools to mitigate environmental challenges while advancing quality education in a post-crisis area.
Over a span of just two years, the school achieved remarkable results:
- Diverted 100 tons of organic waste from landfills annually.
- Reduced monthly energy costs by 80%.
- Enhanced canteen offerings and educational programs.
- Increased crop yields by 30-60%.
- Provided hands-on sustainable waste management training to 240 students.
- Generated a sustainable revenue stream through organic fertilizer sales.
The Challenge: Quality Education in a Post-Crisis Area
ISEE, located in Mile 3, Bamenda, faced numerous challenges, compounded by a lack of infrastructure and resources due to the post-crisis context.
ISEE Profile
- Location: Mile 3, Bamenda, North West Cameroon
- Waste Generation: 200 kg/day (from canteen, kitchen, poultry, pigsty, fish farming, and garden)
Critical Problems Faced
Environmental Crisis
- Lack of waste collection systems leading to illegal dumping and contamination.
- 150 kg of organic waste disposed of daily in landfills.
- Declining soil health from overuse of chemical fertilizers.
- Water quality degradation due to waste and runoff.
Economic Burden
- Weekly energy costs for cooking: 7,000 – 10,000 XAF.
- Limited offerings in the school canteen due to high operational costs.
- Annual fertilizer and pesticide expenses: 150,000 – 300,000 XAF.
- Rising post-COVID fertilizer costs reduced agricultural output.
Knowledge Gap
- Limited understanding of sustainable waste management among staff and students.
- No integrated climate action course or focus on organic farming.
- Lack of awareness of waste-to-resource possibilities.
The Solution: Green Waste Center (GWC) solution
ISEE’s transformative journey began when its director, Mr. Sengka, discovered the GWC solution at the Israel-Cameroon Seminar in Yaoundé in 2023. Intrigued by the potential to turn organic waste into valuable resources, he decided to implement this technology on campus.
Key Features of GWC Technology
- Biodigester System: Processes 50 tons of organic waste annually.
- Daily Output: 50 liters of high-quality organic fertilizer.
- Energy Production: Biogas covers 80% of canteen cooking needs.
- Waste Processing: 100% of ISEE’s organic waste is now recycled.
